OkHttp使用实例

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'
• json处理包
  • 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();
                  }
              });
          }
      }
  
  }
