okhttpClient 使用示例

 1  @Autowired
 2     private OkHttpClient okHttpClient;
 3 
 4     @PostMapping("testOkHttp")
 5     public Result testOkHttp(@RequestParam("code") String code) throws IOException {
 6         Result result = new Result(Code.INTERNAL_SERVER_ERROR, null, "fail");
 7 
 8         //1. 获取参数 access_token string 接口调用凭证
 9         Result getReqParam = getAccessToken();
10         Map<String, String> map = (Map<String, String>) getReqParam.getData();
11 
12         if (null == map) {
13             String phoneURL = "https://api.weixin.qq.com/wxa/business/getuserphonenumber?access_token=" + map.get("access_token");
14 
15             JSONObject code1 = new JSONObject();
16             code1.put("code", code);
17             String content = JSONObject.toJSONString(code1);
18             RequestBody body = RequestBody.create(content, okhttp3.MediaType.parse("application/json"));
19             Request request = new Request.Builder()
20                     .url(phoneURL)
21                     .method("POST", body)
22                     .addHeader("Accept", "application/json")
23                     .addHeader("Content-type", "application/json")
24                     .build();
25             Response response = okHttpClient.newCall(request).execute();
26             System.out.println("response = " + response);
27         }
28         return result;
29     }
