内网离线-使用百度原生地图

须知

1.首先先阅读文件介绍了解之后,把项目运行测试之后在修改

2.详细讲解:csdn博客:https://blog.csdn.net/weixin_53579656/article/details/135140866?spm=1001.2014.3001.5501

文件介绍-public/static-百度地图压缩资源文件,迁移到别的项目时整个文件直接搬过去
  • images:地图中图标,例如:树、建筑物等
  • modules: 所需要的js模块
  • bmap_offline_api_v3.0.min.js: 创建地图,包含各种地图上操作的api等
  • m4.png: 聚合图标,上图中的紫色图
  • map_load.js: 初始化一些全局变量,包括文件路径,瓦片图加载路径,动态加载bmap_offline_api_v3.0.min.js文件等
  • MarkerClusterer_min.js: 实现点聚合
  • TextIconOverlay_min.js: 点聚合相关
文件介绍-public/index.html-引入上面地图资源包,迁移到别的项目时整个文件直接搬过去(3个)
  • 不引入会报错windows.BMap
文件介绍-utils工具文件-map-resource/压缩包-地图瓦片图下载程序
  • 直接解压-默认会在c盘下添加一个MapDownload文件夹
  • 解压之后-打开文件夹-点击imaps.exe打开程序
  • 打开程序-左上角-地图-选择自己需要地图
文件介绍-utils工具文件-map-image/压缩包-下载好的瓦片图
  • 文件太大-放在csdn:

  • win+r-打开cmd-npm全局安装serve

  • npm install -g serve
  • 解压压缩包-进入baidumaps文件夹-上面打开cmd窗口运行命令-serve

  • serve
  • 看到端口号-运行成功

优缺点-须知
须知

1.内网离线情况下我们访问不了百度数据资源,所有只有把数据资源下载在本地启动服务才可以解决这个问题

2.确实可以满足基本的需求

3.地图放大,缩小,控件,定位

4.加载那里的地图我们首先要下载地图瓦片图,然后地图中心点定位在哪里就会加载的地图

5.地图的放大等级我们要控制起来,因为是下载的瓦片图要对应

6.瓦片图下载等级最好下载,11-15,刚好铺满全屏,再多就下载很慢

7.开发时候我们用npm下载serve,把地图资源从本机运行起来(直接serve)

8.所有地址最好写127.0.0.1和localhost方便测试(因为你后续直接断开网线测试时候,你就只能访问自己)

瓦片图加载报错-404解决

1.瓦片图,就是把一个地图区域根据放大等级分割成等额大小图片进行加载

1.首先确定地图中心点经纬度和下载地图瓦片图是否是一致的

2.瓦片图下载等级和代码地图限制放大等级是否一样(比如地图放大19级,但是下载地图没有19级图片也会报错)

3.用serve启动好本地图片资源后-查看map_load.js文件(一般默认不用改)

4..把404图片路径复制到本机浏览器看是否能访问

优点

1.引入项目比较轻便-确实在内网情况下可以使用(不能访问外网情况下-离线)

缺点

1.鼠标滚动的时候,会调用百度的api报错,但不影响使用

2.百度api会失效,比如逆地址解析,没有建立百度资源连接带身份(就是没有在public/index-正常引入百度地图)

3.如果单纯地图展示看,定位-可以,要使用api不满足-目前还没找到解决方案
