1.get請求:

/** * *okhttp get請求 * */public class MainActivity extends AppCompatActivity {    private static final String TAG = "MainActivity";    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        /**         * 建立okhttpClient對象         * */        OkHttpClient mOkHttpClient = new OkHttpClient();        /**         *建立Request對象         **/        final Request request = new Request.Builder()                .url("http://v.juhe.cn/toutiao/index?type=top&key=3f8238bb55566d2b3f0d2204a5e9631f")                .build();        /**         * new Call         * */        Call call = mOkHttpClient.newCall(request);        /**         * 請求調度         * */        call.enqueue(new Callback()        {            @Override            public void onFailure(Call call, IOException e) {                Log.e(TAG, "onFailure: "+e.toString());            }            @Override            public void onResponse(Call call, Response response) throws IOException {                String htmlStr =  response.body().string();                Log.d(TAG, "onResponse() called with: " + "call = [" + call + "], response = [" + htmlStr + "]");            }        });    }}

2，post請求：

/** * * okhttp  post請求 * */public class MainActivity extends AppCompatActivity {    private static final String TAG = "MainActivity";    /**     * 請求地址     * */    String URL = "這裡為請求地址";    JSONObject obj = new JSONObject();    String sss;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        /**         * post請求體為json字串         * */        try {            obj.put("name", "123");            obj.put("pwd", "456");            sss = obj.toString();            post(URL, sss);        } catch (Exception e) {            e.printStackTrace();        }    }   public void post(String url, String json) throws IOException {        OkHttpClient client = new OkHttpClient();        MediaType JSON = MediaType.parse("application/json; charset=utf-8");        RequestBody body = RequestBody.create(JSON, json);        Request request = new Request.Builder().url(url).post(body).build();        client.newCall(request).enqueue(new Callback() {            @Override            public void onFailure(Call call, IOException e) {                Log.e(TAG, "onFailure: "+e.toString() );            }            @Override            public void onResponse(Call call, Response response) throws IOException {                Log.i(TAG, "onResponse*: "+response.body().string());            }        });            }}
