Android网络请求

首先添加相关库

compile 'com.google.code.gson:gson:2.3.1'
compile 'com.squareup.okhttp3:okhttp:3.2.0'
compile 'com.zhy:okhttputils:2.6.2'

默认情况下，将直接使用okhttp默认的配置生成OkhttpClient，如果你有任何配置，记得在Application中调用initClient方法进行设置

     OkHttpClient okHttpClient = new OkHttpClient.Builder()
            //  .addInterceptor(new LoggerInterceptor("TAG"))
              .connectTimeout(10000L, TimeUnit.MILLISECONDS)
              .readTimeout(10000L, TimeUnit.MILLISECONDS)
              //其他配置
             .build();
    OkHttpUtils.initClient(okHttpClient);

自定义CallBack

import com.google.gson.Gson;
import com.zhy.http.okhttp.callback.Callback;
import okhttp3.Response;
/**
 * Created by linqinbin on 2017/3/26.
 */
public abstract class LoginCallback extends   Callback<LoginResponse> {
  @Override
  public LoginResponse parseNetworkResponse(Response   response, int id) throws Exception {
      String string = response.body().string();
      LoginResponse loginResponse = new Gson().fromJson(string,   LoginResponse.class);
      return loginResponse;
  }
}

自定义modal

public class LoginResponse implements Serializable {
  public int user_id;
  public String sid;
  public String access_token;
}

异步请求（baseRequest请求的参数对象modal）

                  OkHttpUtils
                    .postString()
                    .url("http://120.26.106.68:8282/api_v1.php")
                    .content(new Gson().toJson(baseRequest))
                    .mediaType(MediaType.parse("application/json; charset=utf-8"))
                    .build()
                    .execute(new LoginCallback() {
                        @Override
                        public void onError(Call call, Exception e, int id) {
                            println(e.getMessage());
                            Toast.makeText(MainActivity.this,"error",Toast.LENGTH_LONG).show();
                        }

                        @Override
                        public void onResponse(LoginResponse response, int id) {
                            println(response.toString());
                            Toast.makeText(MainActivity.this,response.user_id+response.access_token+response.sid,Toast.LENGTH_LONG).show();

                        }
                    });

同步请求

Response response = OkHttpUtils
.get()//
.url(url)//
.tag(this)//
.build()//
.execute();
//execute方法不传入callback即为同步的请求，返回Response。
