1 public class HttpBaseService { 2  3     private OkHttpClient client = new OkHttpClient(); 4     private static final MediaType JSON = MediaType.parse("application/json; charset=utf-8"); 5     public String sendGetRequest(String url){ 6         Request request = new Request.Builder().url(url).build(); 7         Response response = null; 8         try { 9             response = client.newCall(request).execute();10             if (response.isSuccessful()) {11                 return response.body().string();12             }13         } catch (IOException e) {14             e.printStackTrace();15         }16         return "";17     }18 19     public int sendDelRequest(String url){20         Request request = new Request.Builder().url(url).delete().build();21         return sendOperateRequest(request);22     }23 24     public int sendPostRequest(String url,String json){25 //        RequestBody formBody = new FormEncodingBuilder()26 //                .add("platform", "android")27 //                .add("name", "bug")28 //                .add("subject", "XXXXXXXXXXXXXXX")29 //                .build();30         RequestBody body = RequestBody.create(JSON,json);31         Request request = new Request.Builder().url(url).post(body).build();32         return sendOperateRequest(request);33     }34     public int sendPutRequest(String url,String json){35         RequestBody body = RequestBody.create(JSON,json);36         Request request = new Request.Builder().url(url).put(body).build();37         return sendOperateRequest(request);38     }39 40     private int sendOperateRequest(Request request){41         Response response = null;42         try {43             response = client.newCall(request).execute();44             if (response.isSuccessful()) {45                 return 0;46             }47         } catch (IOException e) {48             e.printStackTrace();49         }50         return -1;51     }52 }
