OkHttp完美封装，用一行代码搞定外部请求，使用起来很方便

OkHttp

OKHttpUtil在JAVA的世界中 ， Http客户端之前一直是Apache家的HttpClient占据主导 ， 但是由于此包较为庞大 ， API又比较难用 ， 因此并不使用很多场景 。而新兴的OkHttp、Jodd-http固然好用 ， 但是面对一些场景时 ， 学习成本还是有一些的 。
很多时候 ， 我们想追求轻量级的Http客户端 ， 并且追求简单易用 。而OKHttp是一套处理 HTTP 网络请求的依赖库 ， 由 Square 公司设计研发并开源 ， 目前可以在 Java 和 Kotlin 中使用 。
对于 Android App来说 ， OkHttp 现在几乎已经占据了所有的网络请求操作 ， 对于服务器端请求外部接口也是必备的选择。针对OKHttp ， OkHttpUtil做了一层封装 ， 使Http请求变得无比简单 。
OKHttpUtil 功能

  • 根据URL自动判断是请求HTTP还是HTTPS ， 不需要单独写多余的代码 。
  • 默认情况下Cookie自动记录 ， 比如可以实现模拟登录 ， 即第一次访问登录URL后后续请求就是登录状态 。
  • 自动识别304跳转并二次请求
  • 支持代理配置
  • 支持referer配置
  • 支持User-Agent配置
  • 自动识别并解压Gzip格式返回内容
  • 支持springboot 配置文件
  • 极简的封装调用
OKHttpUtil使用maven引入

GET最简单的使用莫过于用HttpUtil工具类快速请求某个接口：
Response response = HttpUtil.get("https://github.com/search", Pair.of("q", "okhttp"));System.out.println("response = " + response);POST一行代码即可搞定 ， 当然Post请求也很简单：
# JSON 格式的bodyResponse post = HttpUtil.post("https://oapi.dingtalk.com/robot/send?access_token=27f5954ab60ea8b2e431ae9101b1289c138e85aa6eb6e3940c35ee13ff8b6335", "{"msgtype": "text","text": {"content":"【反馈提醒】我就是我, 是不一样的烟火"}}");System.out.println("post = " + post);# form 请求Map<String, Object> formParams = new HashMap<>(16);formParams.put("username", "admin");formParams.put("password", "admin123");Response response = HttpUtil.postForm("http://192.168.1.13:9100/auth/login",formParams);System.out.println("response = " + response);返回格式为JSON的 可以使用 HttpJsonUtil 自动返回JsonObject
JSONObject object=HttpJsonUtil.get("https://github.com/search",Pair.of("q","http"),Pair.of("username","agonie201218"));System.out.println("object = "+object);文件上传File file=new File("C:\Users\andanyang\Downloads\Sql.txt");Map<String, Object> formParams=new HashMap<>();formParams.put("key","test");formParams.put("file",file);formParams.put("token","WXyUseb-D4sCum-EvTIDYL-mEehwDtrSBg-Zca7t:qgOcR2gUoKmxt-VnsNb657Oatzo=:eyJzY29wZSI6InpoYW56aGkiLCJkZWFkbGluZSI6MTY2NTMwNzUxNH0=");Response response=HttpUtil.upload("https://upload.qiniup.com/",formParams);System.out.println(response);下载文件HttpUtil.down("https://gitee.com/admin4j/common-http","path/");HttpRequest 链式请求# getResponse response=HttpRequest.get("https://search.gitee.com/?skin=rec&type=repository").queryMap("q","admin4j").header(HttpHeaderKey.USER_AGENT,"admin4j").execute();System.out.println("response = "+response);# post formResponse response=HttpRequest.get("http://192.168.1.13:9100/auth/login").queryMap("q","admin4j").header(HttpHeaderKey.USER_AGENT,"admin4j").form("username","admin").form("password","admin123").execute();System.out.println("response = "+response);post form 日志
