基于jdk11和基于apache-httpclient的http请求工具类

1.基于apache-httpclient

需要引入依赖

  <dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.3.5</version></dependency>

//        Map<String, String> loginParamMap = new HashMap<>();
//        loginParamMap.put("username", "admin");
//        //密码admin 密码MD5加密32位
//        String password = DigestUtil.md5Hex("admin");
//        loginParamMap.put("password", password);
//        //String res = HttpUtil.sendGet(WVP_URL + WvpVideoUrlEnums.登录.getUrl(), HttpUtil.asUrlParams(loginParamMap));
//        String res = get("http://10.1.7.33:38080" + WvpVideoUrlEnums.登录.getUrl(), loginParamMap);
//        System.out.println("登录结果----->" + res);
//    }}

说明:写这两个工具类的起因是客户端发起请求登录服务端成功后，后续请求需要携带服务端返回的响应头cookie会话信息来鉴权，否则后续请求会报401
