Http's Gorgeous Client

Define HttpClient's Abstract Interface And Provide Multiple Implementations

introduction

本项目针对http协议定义了所有http实现之上的接口来描述一个http请求,使用者只需要面对同一套语义化的接口, 如果需要切换http的实现,可以做到完全无代码修改。支持GET、POST、文件上传下载等,目前适配了以下项目: OKHttp3、ApacheHttpComponents、HttpURLConnection、Jodd-Http

这一套接口基本覆盖了一个Http请求的所有参数,接口的使用也是简单的、统一的、一致的、连缀的。对URL、Header、Body、Form、文件上传提供最大的支持。

uni既作unique,是一个比较特别的项目。 又作unify,希望统一http的请求方式,统一市面上的http客户端实现。

项目的两个亮点:

  1. http语义化的接口设计,简单的、统一的、一致的、连缀的接口使用体验
  2. 可以做到无代码修改切换Http请求的实现,而无需散弹式修改

features

  • SmartHttpClient接口体系:基于Request(HttpRequest)-Response,可以通过设置一个特定过程的组件替换默认实现
  • SmartHttpClient接口继承于HttpRequestHttpClientSimpleHttpClient,前者提供基于HttpRequest的请求,后者提供简单点的参数请求方式

how to import it?

源码使用

下载本项目,gradle clean build得到的jar包引入工程即可。本项目依赖于utils

项目管理工具导入

项目已经发布至 jcentermavenCentral (2.0.1之前)和jitpack(v2.0.2开始)

Gradle:

【mavenCentral和jcenter】

compile 'top.jfunc.network:unihttp-jdk:${version}'
compile 'top.jfunc.network:unihttp-apache:${version}'
compile 'top.jfunc.network:unihttp-okhttp3:${version}'
compile 'top.jfunc.network:unihttp-jodd:${version}'

【jitpack】

compile 'com.gitee.xxssyyyyssxx.unihttp:unihttp-jdk:${version}'
compile 'com.gitee.xxssyyyyssxx.unihttp:unihttp-apache:${version}'
compile 'com.gitee.xxssyyyyssxx.unihttp:unihttp-okhttp3:${version}'
compile 'com.gitee.xxssyyyyssxx.unihttp:unihttp-jodd:${version}'

SpringBoot环境下更简单,引入相应的starter即可,就可以直接使用SmartHttpClient的实例,当然你可以配置一些参数。

how to use it?

面向SmartHttpClient

  1. 可以使用HttpUtil获取一个实现(基于ServiceLoader加载),或者自己实例化一个;
  2. 在SpringBoot项目中,用Bean注入;
  3. HttpUtil实现了对接口SmartHttpClient的完全静态化代理,一句话实现Http请求。
  4. 定义接口并标注HttpService注解,配置后直接注入接口即可(类似Retrofit、Mapper)
@Configuration
public class HttpConfig {

    @Bean("smartHttpClient")
    public SmartHttpClient smartHttpClient(){
        //如果要更换http的实现或者做更多的事情,可以对此bean进行配置
        SmartHttpClient smartHttpClient = new JdkSmartHttpClient();
        // new OkHttp3SmartHttpClient();
        // new JoddSmartHttpClient();
        // new ApacheSmartHttpClient(){
                //重写某些方法
        };
        smartHttpClient.setConfig(Config.defaultConfig()...);//设置baseUrl...
        retrun smartHttpClient;
    }

当拿到实例之后,就可以使用接口定义的所有的方法用于http请求。

https://gitee.com/xxssyyyyssxx/unihttp/blob/master/unihttp-apache/src/test/java/top/jfunc/http/MultiRequestTest.java https://gitee.com/xxssyyyyssxx/unihttp/blob/master/unihttp-jdk/src/test/java/top/jfunc/http/MultiRequestTest.java https://gitee.com/xxssyyyyssxx/unihttp/blob/master/unihttp-jodd/src/test/java/top/jfunc/http/MultiRequestTest.java https://gitee.com/xxssyyyyssxx/unihttp/blob/master/unihttp-okhttp3/src/test/java/top/jfunc/http/MultiRequestTest.java

下面演示几种用法:

  1. Request代表所有请求的变量,支持链式编程
  2. SmartHttpClient接口的实现类完成真正的请求
  3. Response代表返回信息,可以根据需要转换为字节数组、字符串。。。

GET:

Response response = http.get(Request.of(url).setIgnoreResponseBody(false).setIncludeHeaders(true).addHeader("saleType" , "2").setResultCharset("UTF-8"));
System.out.println(response);
System.out.println("headers:" + response.getHeaders());

String s = http.get(url);
System.out.println(s);

Request request = Request.of(url).addParam("xx" , "xx").addParam("yy" , "yy").addHeader("saleType" , "2").setResultCharset("UTF-8");
byte[] bytes = http.getAsBytes(request);
System.out.println(bytes.length);
System.out.println(new String(bytes));

request = Request.of(url).setFile(new File("C:\\Users\\xiongshiyan\\Desktop\\yyyy.txt"));
File asFile = http.getAsFile(request);
System.out.println(asFile.getAbsolutePath());

POST:

Request request = Request.of(url).setIncludeHeaders(true).addHeader("ss" , "ss").addHeader("ss" , "dd").setBody("{\"name\":\"熊诗言\"}").setContentType(JSON_WITH_DEFAULT_CHARSET).setConnectionTimeout(10000).setReadTimeout(10000).setResultCharset("UTF-8");
Response post = http.post(request);
System.out.println(post.getBody());
System.out.println(post.getHeaders());

String s = http.postJson(url, "{\"name\":\"熊诗言\"}");
System.out.println(s);

request = Request.of(url).addParam("xx" , "xx").addParam("yy" , "yy").setContentType(FORM_URLENCODED);
Response response = http.post(request);
System.out.println(response.getBody());

UPLOAD:

FormFile formFile = new FormFile(new File("E:\\838586397836550106.jpg") , "filedata",null);
Request request = Request.of(url).addHeader("empCode" , "ahg0023")
        .addHeader("phone" , "15208384257").addFormFile(formFile).setIncludeHeaders(true);
Response response = httpClient.upload(request);
System.out.println(response.getBody());
System.out.println(response.getHeaders());

多文件及带参数的上传:

FormFile formFile = new FormFile(new File("E:\\838586397836550106.jpg") , "filedata",null);
FormFile formFile2 = new FormFile(new File("E:\\BugReport.png") , "filedata2",null);
Request request = Request.of(url).addHeader("empCode" , "ahg0023")
        .addHeader("phone" , "15208384257").addFormFile(formFile2).addFormFile(formFile).setIncludeHeaders(true);

request.addParam("k1", "v1").addParam("k2" , "v2");
Response response = httpClient.upload(request);
System.out.println(response.getBody());
System.out.println(response.getHeaders());

对SmartHttpClient设置全局默认参数

http.setConfig(Config.defaultConfig()
            .setBaseUrl("https://fanyi.baidu.com/")
            .addDefaultHeader("xx" , "xx")
            .setDefaultBodyCharset("UTF-8")
            .setDefaultResultCharset("UTF-8")
            .setDefaultConnectionTimeout(15000)
            .setDefaultReadTimeout(15000)

    //.....
   );

类似MyBatis接口使用方式

1.配置HttpService接口扫描 2.定义如下一样的接口

    @Configuration
    public class SomeConfiguration{
        @Bean
        public SmartHttpClient smartHttpClient(){
            Config config = Config.defaultConfig().setBaseUrl("xxxxx);
            SmartHttpClientImpl smartHttpClient = new SmartHttpClientImpl();
            smartHttpClient.setConfig(config);
            return smartHttpClient;
        }
        //以下配置可以扫描 top.jfunc.network.controller.client 包下的标注 @HttpService 注解的接口
        @Bean
        public HttpServiceCreator httpServiceCreator(SmartHttpClient smartHttpClient){
            return new HttpServiceCreator().setSmartHttpClient(smartHttpClient);
        }
        @Bean
        public HttpServiceScanConfigure httpServiceScanConfigure(){
            HttpServiceScanConfigure httpServiceScanConfigure = new HttpServiceScanConfigure(httpServiceCreator(smartHttpClient()));
            httpServiceScanConfigure.setAnnotationClassScan(HttpService.class);
            httpServiceScanConfigure.setScanPackages("top.jfunc.network.controller.client");
            return httpServiceScanConfigure;
        }
    }
    



@HttpService
public interface InterfaceForTestHttpService {

    @GET
    Response request(HttpRequest httpRequest);

    @GET("/get/{q}")
    Response list(@Path("q") String q, @Query("xx") int xx);
    @GET("/get/query")
    Response queryMap(@QueryMap Map<String, String> map);
    @GET
    Response url(@Url String url);

    @GET("get/query")
    Response header(@Header("naked") String naked);

    @Headers({"xx:xiongshiyan","yy:xsy"})
    @GET("get/query")
    Response headers(@Header("naked") String naked);

    @GET("get/query")
    Response headerMap(@HeaderMap Map<String, String> map);



    @GET("/get/query")
    Response download();

    @POST("/post/{id}")
    Response post(@Path("id") String id, @Body String xx);

    @Multipart
    @POST("/upload/only")
    Response upload(@Part FormFile... formFiles);
    @Multipart
    @POST("/upload/withParam")
    Response uploadWithParam(@Part("name") String name, @Part("age") int age, @Part FormFile... formFiles);

    @FormUrlEncoded
    @POST("/post/form")
    Response form(@Field("name") String name, @Field("age") int age);
    @FormUrlEncoded
    @POST("/post/form")
    Response formMap(@FieldMap Map<String, String> params);
}

建议的最佳实践为:

  1. 设置body的同时应该设置Content-Type
  2. 针对同一组请求可以使用一个SmartHttpClient,可以对他进行一些参数设置
  3. 使用拦截器而非复写父类方法达到拦截目的

更多用法等待你探索,本人才疏学浅,难免有考虑不周到的地方,请不吝赐教。

提供了服务端和客户端的测试工程,可以clone下来运行。

https://gitee.com/xxssyyyyssxx/http-client-test

如果你想实现自己的,只需要继承 top.jfunc.http.smart.AbstractSmartHttpClient , 参考top.jfunc.http.smart.DemoImpl实现抽象方法即可。实现方法可以参考httpclient-jdk、apache、okhttp3、jodd等。

http模块的架构设计和使用方式见 CSDN博客

一个http请求工具类的接口化(接口设计)

一个http请求工具类的接口化(多种实现)

项目采用双接口并行设计模式,一种是面向接口实现者的 HttpTemplate-SmartHttpTemplate 功能接口 ,主要的功能是模拟Http的参数、header等;一种是面向终端用户调用者的 HttpClient-SmartHttpClient 用户接口 。具体实现类通过实现两组接口,后者接口实现最终调用前者的接口实现。这样做的好处是互不影响,实现者可以无限优化 HttpTemplate、SmartHttpTemplate 的实现类,而对使用者几无影响。

HttpTemplate、HttpClient接口基于方法来模拟Http的参数、header等;SmartHttpTemplate继承于HttpTemplate,SmartHttpClient接口继承于HttpClient,且基于Request来模拟Http的参数、header,这样更容易优化、更容易使用。
