重试拦截器：
注意：两处while是因为如果请求中出现异常，也能进行重试，比如超时，后面会有例子。
网络拦截器，打印请求、响应时间、响应状态码，响应内容
1、带参数的get请求
测试:
String url = "http://localhost:8080/test/12346/query";Map params = new HashMap<>();params.put("aaa","111");params.put("bbb","222");HttpUtils httpUtils = HttpUtils.getInstance();httpUtils.get(url,params);打印日志如下：[main][2019-09-21 10:19:02.072] [INFO] [NetworkIntercepter.intercept:40] responseTime= 62, requestUrl= http://localhost:8080/test/12346/query?aaa=111&bbb=222, params=, responseCode= 200, result= {"result_code":"success","data":{"aaa":"111"},"path":"/test/12346/query"}
2、不带参数的get请求
测试：
String url = "http://localhost:8080/test/12346/query?ccc=1&ddd=2";HttpUtils httpUtils = HttpUtils.getInstance();httpUtils.get(url);打印日志如下：[main][2019-09-21 10:25:46.943] [INFO] [NetworkIntercepter.intercept:38] responseTime= 11, requestUrl= http://localhost:8080/test/12346/query?ccc=1&ddd=2, params=, responseCode= 200, result= {"result_code":"success","data":{"aaa":"111"},"path":"/test/12346/query"}
测试：
Gson gson = new Gson();String url = "http://localhost:8080/test/12346/query";Map params = new HashMap<>();params.put("aaa","111");params.put("bbb","222");Map bodyMap = new HashMap<>();bodyMap.put("name","zhangsan");bodyMap.put("age",15);HttpUtils httpUtils = HttpUtils.getInstance();httpUtils.post(url,params,gson.toJson(bodyMap));打印日志[main][2019-09-21 10:37:04.577] [INFO] [NetworkIntercepter.intercept:38] responseTime= 304, requestUrl= http://localhost:8080/test/12346/query?aaa=111&bbb=222, params={"name":"zhangsan","age":15}, responseCode= 200, result= {"result_code":"success","data":{"aaa":"111"},"path":"/test/12346/query"}
2、post发送json
测试：
Gson gson = new Gson();String url = "http://localhost:8080/test/12346/query";Map bodyMap = new HashMap<>();bodyMap.put("name","zhangsan");bodyMap.put("age",15);HttpUtils httpUtils = HttpUtils.getInstance();httpUtils.post(url,gson.toJson(bodyMap));
打印日志：
[main][2019-09-21 10:44:00.835] [INFO] [NetworkIntercepter.intercept:38] responseTime= 17, requestUrl= http://localhost:8080/test/12346/query, params={“name”:”zhangsan”,”age”:15}, responseCode= 200, result= {“result_code”:”success”,”data”:{“aaa”:”111″},”path”:”/test/12346/query”}
3、post发送表单
测试：
String url = "http://localhost:8080/test/12346/query";Map params = new HashMap<>();params.put("aaa","111");params.put("bbb","222");HttpUtils httpUtils = HttpUtils.getInstance();httpUtils.post(url,params);打印日志：[main][2019-09-21 10:49:54.136] [INFO] [NetworkIntercepter.intercept:38] responseTime= 21, requestUrl= http://localhost:8080/test/12346/query, params=aaa=111&bbb=222, responseCode= 200, result= {"result_code":"success","data":{"aaa":"111"},"path":"/test/12346/query"}
1、404重试
测试：
String url = "http://localhost:8080/test/12346/query2";Map params = new HashMap<>();params.put("aaa","111");params.put("bbb","222");HttpUtils httpUtils = HttpUtils.getInstance();httpUtils.post(url,params);日志打印：
[main][2019-09-21 10:56:20.495] [INFO] [NetworkIntercepter.intercept:38] responseTime= 26, requestUrl= http://localhost:8080/test/12346/query2, params=aaa=111&bbb=222, responseCode= 404, result= {“timestamp”:1569034580,”status”:404,”error”:”Not Found”,”message”:”Not Found”,”path”:”/test/12346/query2″}
[main][2019-09-21 10:56:20.506] [INFO] [NetworkIntercepter.intercept:38] responseTime= 4, requestUrl= http://localhost:8080/test/12346/query2, params=aaa=111&bbb=222, responseCode= 404, result= {“timestamp”:1569034580,”status”:404,”error”:”Not Found”,”message”:”Not Found”,”path”:”/test/12346/query2″}
[main][2019-09-21 10:56:20.512] [INFO] [NetworkIntercepter.intercept:38] responseTime= 4, requestUrl= http://localhost:8080/test/12346/query2, params=aaa=111&bbb=222, responseCode= 404, result= {“timestamp”:1569034580,”status”:404,”error”:”Not Found”,”message”:”Not Found”,”path”:”/test/12346/query2″
重试了2次，共请求3次
2、超时重试
日志打印：
[main][2019-09-21 10:59:30.086] [ERROR] [NetworkIntercepter.intercept:33] timeout
