# OkHttp使用实例 #

### 依赖 ###

*  OkHttp包
    
     *  compile 'com.squareup.okhttp3:okhttp:3.6.0'
 *  OkHttp依赖包
    
     *  compile 'com.squareup.okio:okio:1.11.0'

     *  compile 'com.google.code.gson:gson:2.8.0'
 *  图示

### 具体例子【封装的两个类，可以直接调用】 ###

*  get方式为例【重在理解原理】
    
    #  #
    
        import android.app.Activity;
        import java.io.IOException;
        import okhttp3.Call;
        import okhttp3.Callback;
        import okhttp3.OkHttpClient;
        import okhttp3.Request;
        import okhttp3.Response;
        
        public class OkHttpManager extends Activity {
            private Activity activity;
        
            public OkHttpManager(Activity activity) {
                this.activity = activity;
            }
        
            public void get(String url) {
                OkHttpClient client = new OkHttpClient();
                Request request = new Request.Builder().get().url(url).build();
                Call call = client.newCall(request);
                call.enqueue(new Callback() {
                    @Override
                    public void onFailure(Call call, IOException e) {
                        ToastUtil.showToast(activity, "Get 失败");
                    }
                    @Override
                    public void onResponse(Call call, final Response response) throws IOException {
                        final String responseStr = response.body().string();
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                ToastUtil.showToast(activity, responseStr);
                            }
                        });
                    }
                });
            }
        }
 *  弹出框辅助类
    
    #  #
    
        import android.app.Activity;
        import android.util.Log;
        import android.widget.Toast;
        
        public class ToastUtil {
        
            public static void showToast(final Activity activity, final String message) {
                if ("main".equals(Thread.currentThread().getName())) {
                    Log.e("ToastUtil", "主线程!");
                    Toast.makeText(activity, message, Toast.LENGTH_SHORT).show();
                } else {
                    activity.runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            Log.e("ToastUtil", "不在主线程！");
                            Toast.makeText(activity, message, Toast.LENGTH_SHORT).show();
                        }
                    });
                }
            }
        
        }
