公司内部一般都是用自研的rpc pigeon

但是涉及到第三方合作都会使用http请求，如果你尝试使用httpclient你又会被众多的版本和不同的api所困扰，经常忘记设置线程数，忘记设置超时时间等。

就算你搞定了httpclient，你会发现与第三方定义的请求方式和描述难于维护，交于第二个维护的时候代码不容易阅读，于是基于javaAPI来请求http请求的想法萌生，就有了如下的微框架。

本框架有如下优势：

1. 基于httpclient, 仅暴露常用的配置, 填掉了常见的坑
2. 接口设计参考jsoup, 简易的语法让人耳目一新
3. 支持所有的请求方法:GET,POST,PUT,DELETE,PATCH,HEAD,OPTIONS,TRACE
4. 出参入参对json极为友好, 自动解析返回对象to pojo
5. 可以像rpc一样基于java api发送http请求, 代码更加规范稳定, 易于管理
6. 当返回值为HttpResult时, 调用失败也不会抛出异常.
7. 支持返回值取json path, 例如:msg.user.id/msg.user[1].id 参考测试包下 ResultJsonPathTest
8. 支持设计重试次数, 建议get请求都有重试机制, 参考测试包下 RetryTest
9. 支持上传各种类型的文件, 支持File/InputStream/byte[]/base64上传, 参考测试包下 UploadFileTest
10. 支持@PathVariable 如 http://.com/{key}/info -> http://.com/xiaojie.chen/info, 参考测试包下 SimpleTest
11. 支持自定义httpclient, 参考 CustomHttpClientTest
12. 自定义请求拦截器可以作于自定义授权
13. 日志清晰，排查case十分方便
14. 支持自定义植入监控，如大众点评的cat
15. 开发者正处壮年，有问题立即反馈~~哈哈哈

使用入门：

最简单的实例，先定义个httpapi

public interface SimpleHttpApi {      //get     @RequestMapping(value = "/simple/{loginId}", method = HttpMethod.GET)     Response<UserLoginModel> getByLoginId(@PathVariable("loginId") int loginId,                                           @RequestParam(value = "employeeId") String employeeId,                                           @RequestParam(value = "employeeName") String employeeName,                                           @RequestParam(value = "ad") String ad);       //post     @RequestMapping(value = "/{path}", method = HttpMethod.POST)     HttpResult<Response<UserLoginModel>> addUser5(@RequestBody UserLoginModel userLoginModel,                                                   @PathVariable("path") String path,                                                   @RequestParam(value = "employeeId") String employeeId,                                                   @RequestParam(value = "employeeId") String employeeId2,                                                   @RequestParam(value = "employeeId") String employeeId3,                                                   @RequestParam(value = "employeeName") String employeeName,                                                   @RequestParam(value = "ad") String ad);               //upload     @RequestMapping(value = "/{path}", method = HttpMethod.POST)     HttpResult<Response<String>> upload(@RequestFile("a1.png") InputStream in,                                         @RequestFile("a2.png") File file,                                         @RequestFile("a3.png") byte[] fileBytes,                                         @RequestFile("a4.png") String base64,                                         @PathVariable("path") String path,                                         @RequestParam(value = "employeeId") String employeeId,                                         @RequestParam(value = "employeeId") String employeeId2,                                         @RequestParam(value = "employeeId") String employeeId3,                                         @RequestParam(value = "employeeName") String employeeName,                                         @RequestParam(value = "ad") String ad);          //retry     @RequestMapping(value = "/simple/{loginId}", method = HttpMethod.GET, retryTimes = 1)     HttpResult<Response<UserLoginModel>> getByLoginId(@PathVariable("loginId") String loginId,                                                           @RequestParam(value = "employeeId") String employeeId,                                                           @RequestParam(value = "employeeName") String employeeName,                                                           @RequestParam(value = "ad") String ad);               //jsonPath     @RequestMapping(value = "/simple/list", method = HttpMethod.GET, retryTimes = 1, resultJsonPath = "data[1].employeeName")     String queryUsers();  }

通过java方式调用

HttpInvocationHandler httpInvocationHandler = new HttpInvocationHandler(); httpInvocationHandler.setRequestUrlPrefix(Consts.URL);  SimpleHttpApi simpleHttpApi = (SimpleHttpApi) Proxy.newProxyInstance(Thread.currentThread().getContextClassLoader(),         new Class[]{SimpleHttpApi.class},         httpInvocationHandler);  UserLoginModel userLoginModel = new UserLoginModel(); userLoginModel.setLoginId(1); userLoginModel.setEmployeeId("0016004"); userLoginModel.setEmployeeName("陈孝杰"); userLoginModel.setAd("xiaojie.chen");  Response<UserLoginModel> response = simpleHttpApi.addUser(userLoginModel);  System.out.println(response.getData());
