Google摒弃HttpClient之后 OKHttp第三框架

OkHttp在api 4.4之后替换了HttpClient网络交互，4.4之后看到的就是OkHttp，相信大家使用过api 4.4以后的都知道了吧。

1）OkHttp的Get调用方法

   //初始化，或得一个OkHttp对象

  OkHttpClient client = new OkHttpClient();

  //声明一个Request对象，传入一个request对象返回一个Response对象

   public String run(String url) throws IOException {

    Request request = new Request.Builder()

        .url(url)

        .build();

    try (

Response response = client.newCall(request).execute()) {

        return response.body().string();

    }

  }

2）OkHttp的Post调用方法

        //声明一个JSON的头文件

public static final MediaType JSON= MediaType.parse("application/json; charset=utf-8");

//初始化OkHttp对象

        OkHttpClient client = new OkHttpClient();

       public  String post(String url, String json) throws IOException {

         RequestBody body = RequestBody.create(JSON, json);

         Request request = new Request.Builder() .url(url) .post(body) .build();

         try (Response response = client.newCall(request).execute()) {

         return response.body().string();

       }

   }

// 构造一个json串，作为调用时传入的参数

  public String bowlingJson(String player1, String player2) {

    return "{'winCondition':'HIGH_SCORE',"

        + "'name':'Bowling',"

        + "'round':4,"

        + "'lastSaved':1367702411696,"

        + "'dateStarted':1367702378785,"

        + "'players':["

        + "{'name':'" + player1 + "','history':[10,8,6,7,8],'color':-13388315,'total':39},"

        + "{'name':'" + player2 + "','history':[6,10,5,10,10],'color':-48060,'total':41}"

        + "]}";

  }
