1.5 功能介绍:

 本博客简单实现了博客展示、后台管理、发布博客还有评论等功能,其中后台管理、发布博客和评论功能要在用户登录后才可使用,而后台管理的某些功能普通用户只有查看的权限,并没有分配增删改的权限。

1.6 博客介绍

 由于博客是由博主一人完成的,所以暂且只做了一些简单的功能,部分地方还是有不完善的地方甚至有bug,欢迎各位在本篇博文下评论处指出。

1.7 Tips

 1.7.1

 编写博客的markdown编辑器在文章过长时,编写栏和预览栏可能会有错位,此时可手动拉动预览栏滚动条)

 1.7.2

 暂未设置图片上传功能,涉及图片的上传和使用建议使用网络地址。推荐的图片地址(https://picsum.photos/images#1),使用的时候,将右侧链接的(https://unsplash.it/100/100?image=1002) 1002 改成自己的图片id即可,100/100是图片的尺寸,即长宽。

 1.7.3

 前端的请求没有用baseURL封装到一个js里。

 1.7.4

 由于笔者偷懒,没有使用vuex存储某些共享数据,用的都是sessionstorage。

二.前端开发:

2.1 简介:

 ***https://github.com/asiL-tcefreP/blog-vue***(前端源码地址)  采用了vue.js,前端框架采用了semantic-ui和element-ui,此外还有一些关于页面动态和渲染的js和css类似(animate.css,pricsm等)。此外,需要说明的是,本人后端狗一枚,页面样式是基于网上部分模板样式的修改,其余开发是独立完成的。

2.2 项目介绍

 项目结构采用的是vue-cli3,值得一提的是其中用到的插件还是不错的。

编辑器 Markdown

内容排版 typo.css

动画 animate.css

代码高亮 prism

目录生成 Tocbot

滚动侦测 waypoints

平滑滚动 jquery.scrollTo

二维码生成 qrcode.js

弹幕效果 vue-baberrage

背景的彩带效果 ribbon

统计图 echarts

音乐播放器 vue-aplayer

三.后端开发:

3.1 简介:

 ***https://github.com/asiL-tcefreP/blog***(后端源码地址)

  • 大致框架采用了SpringBoot+MybatisPlus+SpringCloud(Eureka)+ElasticSearch完成的,用redis做缓存中间件,采用微服务的架构。
  • 安全方面采用了SpringSecurity和BCEncrypt
  • 用了jwt来请求访问接口
  • 利用RSA算法对前端发送的重要参数进行加密,经过网关解密后把参数发送到后端服务器。
  • 由于服务器内存和配置的原因,服务器只上线了四个模块 在这里插入图片描述 在这里插入图片描述

项目是由八个模块组成的,

  • blog-common: 博客服务端的实体类
  • blog-encrypt: 博客的服务代理类(从前端接收请求,网关RSA解密后转发给服务端接口)
  • blog-eureka: 微服务注册中心server
  • blog-server: 主体服务端
  • blog-extension: 拓展服务端(留言和友链功能),上线的版本集成了blog-search-api模块,因为阿里云服务器内存太小了
  • blog-search-api: ElasticSearch的服务端,分出一个模块是为了更清晰的展现微服务架构,但是服务器内存太小,所以集成在上述模块中,自己开发可以直接使用本模块
  • blog-article-crawler:爬虫和人工智能模块,用的webmagic框架爬取数据,deeplearning4j做文本分类
  • blog-ai:里面的服务类调用了py脚本来实现古诗词生成

3.3 开发中遇到的一些问题:

3.3.1 关于jwt与zuul

 本人使用自定义注解@LoginRequired来对某些类或者接口进行jwt验证,但是在一开始加入网关微服务的时候,发现后端用了jwt验证的接口一直访问不通过。在浏览器看,发的请求的请求头明明都带上了token,这是一开始百思不得其解的地方之一。

 后来才得知,原来是在网关转发前端的请求后,再把请求转发给后端服务器时,请求头中的token丢失,于是只能在网关filter里面,在转发请求给后端前,手动的把token加到头部。

            //对加密后的数据进行解密
            if (!Strings.isNullOrEmpty(s2)) {
                try {
                    decryptData = rsaService.RSADecryptDataPEM(s2, RsaKeys.getServerPrvKeyPkcs8());
                } catch (BadPaddingException e) {
                    System.out.println("网关发送的是明文数据");
                }
                System.out.println("解密后" + decryptData);
            }

            if (!Strings.isNullOrEmpty(decryptData)) {
                byte[] bytes = decryptData.getBytes();

                //使用RequestContext进行数据的转发

                ctx.setRequest(new HttpServletRequestWrapper(request) {

                    @Override
                    public String getHeader(String name) {
                        return token;
                    }

                    @Override
                    public ServletInputStream getInputStream() throws IOException {
                        return new ServletInputStreamWrapper(bytes);
                    }

                    @Override
                    public int getContentLength() {
                        return bytes.length;
                    }

                    @Override
                    public long getContentLengthLong() {
                        return bytes.length;
                    }
                });
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        return null;
    }
}

3.3.2 关于RSA解密与Json

在这里插入图片描述  获取到前端的加密请求参数时,还有对其进行URLdecode解码,然而加密后的数据中的空格依旧没有转换成加号,此时就得自己用字符串替换。前端传来的数据要进行解码否则就会有%2F,%3D等出现,其次base64编码的+号会变成空格,要对字符串进行处理重新变为+号,关于转码问题可以参考: 这篇文章在这里插入图片描述

3.4 有意思的插件

  • captcha:自动生成验证码
  • commonmark:将markdown格式的文章转换成html格式的显示在页面
  • NeteaseCloudMusicApi:网易云音乐后台数据的api接口

3.5 关于ELK

 之前一直没做项目关于ElasticSearch的整合,是因为不知道项目如果采用了ES后,对数据库的操作该怎么实现。

例如:当我更改数据库的数据时,还要同步ES索引中的数据,这也未免太过繁琐。此外,数据库中的多对多、一对多关系在ES索引中该如何表示?Linux系统下该怎么部署ES?

 后来查阅资料,才明白不一定要把数据库表的所有字段都存在索引中,只需要存我们需要的字段即可,ES的查询速度比mysql确实快的不止一星半点,并且还有IK分词器对搜索词分词,然后进行得分排序显示查询出来的结果。 在这里插入图片描述  然后要说的就是Logstash了,就是他完成了数据库和索引的实时同步(最快就是一分钟同步一次),不过只能实现增量同步。 具体关于ELK的配置,还请各位点击我的这篇文章,其中有详细说明。

3.6 关于AI和爬虫模块

  用了三千篇从csdn上爬取下来的文章做训练集。总共迭代了二十次,词向量维度是200, 在这里插入图片描述 在这里插入图片描述

可以看到的是在第一个Epoch,准确率只有65%,但是在第二个Epoch的时候已经有了明显提升。

第十次Epoch,loss值在0.6左右

第二十次Epoch,loss值在0.4左右

第三十次Epoch,loss值在0.2几左右,但是此时准确率已经达到了96.7%。

在这里插入图片描述

第四十次Epoch,loss值约在0.2,准确率达到97.6%。 训练完成后,用ModelSerializer.writeModel方法将模型持久化即可。 在这里插入图片描述 在这里插入图片描述

  根据爬取下来的三千篇文章的内容和标题做的分词,以及词向量分析,算法就不在此细说了,用的都是别人的,源码中都有。   值得一提的是,在使用webmagic根据页面元素的Xpath获取指定数据的过程还是挺有趣的

在这里插入图片描述

  项目涉及增删改查的部分还是挺好理解的,各位看看源码应该都能理解,所以笔者在此不再赘述。  如果这篇文章对你有帮助,麻烦点个赞,并star一下仓库,有问题请在评论处指出,感谢各位支持!

GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. <one line to give the program's name and a brief idea of what it does.> Copyright (C) <year> <name of author> This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. <signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.
