1.首先在gradle里配置文件
dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:24.2.1' compile 'com.squareup.okhttp3:okhttp:3.0.1' }
2.mainfast加权限
<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
3.贴代码
下面是utils请求类
package com.yueniu.myokhttputil; import java.io.IOException; import java.util.Map; import java.util.concurrent.TimeUnit; import okhttp3.Call; import okhttp3.Callback; import okhttp3.FormBody; import okhttp3.OkHttpClient; import okhttp3.Request; import okhttp3.RequestBody; import okhttp3.Response; /** * Created by maoshenbo on 2017/3/9 9:07. */ public class OkHttp3Util { private static int TimeOut = 120; //单例获取ohttp3对象 private static OkHttpClient okHttp = null; public static synchronized OkHttpClient getInstance(){ if(okHttp == null){ okHttp = new OkHttpClient.Builder() .readTimeout(TimeOut, TimeUnit.SECONDS) .connectTimeout(TimeOut, TimeUnit.SECONDS) .writeTimeout(TimeOut, TimeUnit.SECONDS) .build(); } return okHttp; } /** * 自定义callback */ static class MyCallBack implements Callback { private OkHttpCallBack okHttpCallBack; public MyCallBack(OkHttpCallBack okHttpCallBack) { this.okHttpCallBack = okHttpCallBack; } @Override public void onFailure(Call call, IOException e) { okHttpCallBack.onFailure(e); } @Override public void onResponse(Call call, Response response) throws IOException { okHttpCallBack.onSuccess(response); } } /** * 接口方法 */ public interface OkHttpCallBack{ void onFailure(IOException e); void onSuccess(Response response); } /** * post请求 * @param url * @param map * @param callback */ public static void doPost(String url, Map<String, Object> map, OkHttpCallBack callback){ MyCallBack myCallback = new MyCallBack(callback); FormBody.Builder formBody = new FormBody.Builder(); //解析转化map if (null != map && map.size()>0) { for (Map.Entry<String, Object> entry : map.entrySet()) { formBody.add(entry.getKey(), entry.getValue().toString()); } } RequestBody requestBody = formBody.build(); Request request = new Request.Builder() .url(url) .post(requestBody) .build(); okHttp.newCall(request).enqueue(myCallback); } /** * get请求 * @param url * @param callback */ public static void doGet(String url, OkHttpCallBack callback){ MyCallBack myCallback = new MyCallBack(callback); Request request = new Request.Builder() .url(url) .get() .build(); okHttp.newCall(request).enqueue(myCallback); } }
使用方式
package com.yueniu.myokhttputil; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import java.io.IOException; import java.util.HashMap; import java.util.Map; import okhttp3.Response; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); OkHttp3Util.getInstance().doGet("", new OkHttp3Util.OkHttpCallBack() { @Override public void onFailure(IOException e) { } @Override public void onSuccess(Response response) { } }); Map<String, Object> map = new HashMap<>(); map.put("www", "eeee"); OkHttp3Util.getInstance().doPost("", map, new OkHttp3Util.OkHttpCallBack() { @Override public void onFailure(IOException e) { } @Override public void onSuccess(Response response) { } }); } }
这是单纯的okhttp3的简单封装，学习使用
