Android Okhttp POST提交键值对

以前的项目网络连接那块一直坚持使用HttpClient，总是会出现一些莫名奇妙的问题，现在新的项目使用了OKHttp网络框架，发现超级好用，上网再了解下，发现OkHttp口碑真的不错，对比之下HttpClient简直就是弱爆啦，今天就OKHttp post方式提交键值对的使用提出来，一者为了总结所学的知识，然后也是为了日后项目的偷懒，OKHttp的官方介绍地址，还有OKHttp的github源码,一开始我使用的是2.3的版本，post提交键值对也没啥问题，但是在图片上传方面遇到了bug怎么都解决不掉，再加上我这人喜新厌旧，一怒之下就把OKHttp的版本升到最高的3.4.1版本，升级之后发现变化特别大，在2.3版本中有的类和方法在3.4.1版本中根本就不存在啦，比如说FormEncodingBuilder（）方法，真是没办法啦，只能找文档啦。

现在来说，还使用eclipse作为Android开发Android的童鞋，只能说你太怀旧啦，这里就不说eclipse怎么导入OKHttp啦，对于使用studio的童鞋来说，导入OKHttp特别简单，只需要在gradle中添加两行代码就行。

我们可以在全局变量中初始化一个OKHttpClient并且配置一些比如连接时间的配置，我们就可以不用每向服务器请求一次数据就初始化一个OKHttpClient啦。

 package com.example.keranbin.okhttpdemo;

 import android.app.Application;

 import java.io.File;

 import java.util.concurrent.TimeUnit;

 import okhttp3.Cache;

 import okhttp3.OkHttpClient;

 /**

  * Created by keranbin on 2016/7/26.

  */

 public class APP extends Application {

     public static OkHttpClient okHttpClient;

     public static APP app;

     @Override

     public void onCreate() {

         super.onCreate();

         app=this;

     }

     public static OkHttpClient OkHttpInstance() {

         if (okHttpClient == null) {

             okHttpClient = new OkHttpClient().newBuilder()

                     .connectTimeout(500, TimeUnit.MILLISECONDS)

                     .readTimeout(1000,TimeUnit.MICROSECONDS)

                     .writeTimeout(1000,TimeUnit.MICROSECONDS)

                     .cache(new Cache(app.getExternalCacheDir(), 10 * 1024 * 1024))

                     .build();

             return okHttpClient;

         } else {

             return okHttpClient;

         }

     }

 }

我们不可能每请求一次数据就一个一个的往builder里面add个不停，想了下，干脆把这一块的代码提出来，调用的时候传个Map进来，一个for循环搞定，同时也把Handler传进来，那我们在Activity中不就直接可以操作请求回来的数据了吗。

     public static void Params(Map<String, Object> map, final int code, final Handler handler) {

         Log.i("参数map",map.toString());

         FormBody.Builder builder = new FormBody.Builder();

         if (map != null) {

             for (Map.Entry<String, Object> entry : map.entrySet()) {

                 Log.i("参数:" , entry.getKey() + ":" + entry.getValue());

                 builder.add(entry.getKey(), entry.getValue().toString());

             }

         }

         RequestBody requestBody = builder.build();

         Request request = new Request.Builder().url(URL)

                 .header("Cache-Control", " max-stale=600")

                 .post(requestBody)

                 .build();

         okHttpClient.newCall(request).enqueue(new Callback() {

             @Override

             public void onFailure(Call call, IOException e) {

                 Log.i("网络错误" ,e.toString());

             }

             @Override

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

                 String s = response.body().string().toString();

                 Log.i("数据请求结果:" , s);

                 Message message = handler.obtainMessage();

                 message.what = code;

                 message.obj = s;

                 handler.sendMessage(message);

             }

         });

     }

 }

再看看MainActivity中怎么调用，把封装的Map，还有Code，Handler传过来就OK，就这么简单。

 package com.example.keranbin.okhttpdemo;

 import android.app.Activity;

 import android.os.Bundle;

 import android.os.Handler;

 import android.os.Message;

 import android.widget.TextView;

 import android.widget.Toast;

 import java.util.HashMap;

 import java.util.Map;

 public class MainActivity extends Activity {

     private Handler handler=new Handler(){

         @Override

         public void handleMessage(Message msg) {

             super.handleMessage(msg);

             switch (msg.what){

                 case 0x123:

                     Toast.makeText(MainActivity.this,msg.obj.toString(),Toast.LENGTH_SHORT).show();

                     break;

                 default:

                     break;

             }

         }

     };

     @Override

     protected void onCreate(Bundle savedInstanceState) {

         super.onCreate(savedInstanceState);

         setContentView(R.layout.activity_main);

         Map map=new HashMap();

         //这里只是举个例子，具体的操作要视服务器端需要的数据哈

         map.put("tid","KQ_XjjbglMobileCBS_getJbInitData");

         map.put("ryId","3423423243243243");

         HttpCon.Params(map,0x123,handler);

     }

 }
