okhttp3.2版本使用总结

POST提交json数据

 String url = "http://123.56.153.172:8801/NewSheet/NewSheet";//需要提交到的接口

                    .writeTimeout(30, TimeUnit.SECONDS)//写入超时
                    .build();

                        public void onFailure(Call call, IOException e) {
                            handler.post(new Runnable() {//必须要有这行  一切操作都放在Runnable代码块里
                                @Override

                        public void onResponse(Call call, final Response response) throws IOException {

                            System.out.println("--------json-------" + objInfo.toString());
                            handler.post(new Runnable() {

                                    }
                                }
                            });
                             }
                        });
        } catch (JSONException e) {
            e.printStackTrace();
        }

注意：这里面需要结合下handler使用 

//okhttp使用时必须要先获取到looper
private Handler handler = new Handler(Looper.getMainLooper());

get提交

new Thread(){
    @Override
    public void run() {
        //获取请求对象
        Request request = new Request.Builder().url(url).build();
        try {
            //获取响应体
            ResponseBody body =  clientget.newCall(request).execute().body();
           String s =  body.string();
            System.out.println("返回的数据："+s);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}.start();

post提交字符串

  RequestBody requestBody = RequestBody.create(MediaType.parse("text/x-markdown; charset=utf-8"),"dsahsadsdashjkjdashd");

                Request request = new Request.Builder()
                        .url("http://192.168.1.149:8801/NewSheet/NewSheet")
                        //使用header(name, value)可以设置唯一的name、value。如果已经有值，旧的将被移除，然后添加新的。使用addHeader(name, value)可以添加多值（添加，不移除已有的）。
                        // .addHeader("","")
//                        .header("User-Agent", "OkHttp Headers.java")
//                        .addHeader("Accept", "application/json; q=0.5")
//                        .addHeader("Accept", "application/vnd.github.v3+json")
                        .post(requestBody)
                        .build();
                final Call call= client1.newCall(request);
                handler.post(new Runnable() {
                    @Override
                    public void run() {

                            public void onFailure(Call call, IOException e) {
                                Toast.makeText(MainActivity.this, "请求失败", Toast.LENGTH_SHORT).show();
                            }

                            @Override
                            public void onResponse(Call call, Response response) throws IOException {
                                String s = response.body().string();
                                System.out.println("请求成功" + s);
                            }
                        });
                    }

                });
