Question

调查OKHttp并希望尽可能使用文档声明：“它支持同步阻塞调用和带回调的异步调用”。

但是如何设置回调，或者在收到响应后需要执行一大块代码？我在他们的网站上找不到任何东西。

我应该将呼叫嵌套到Async线程中，如：

AsyncTask.execute(new Runnable() {
@Override
public void run() {
//TODO your background code

    Request request = new Request.Builder()
        .url("http://publicobject.com/helloworld.txt")
        .build();

    client.newCall(request).enqueue(new Callback() {
      @Override public void onFailure(Call call, IOException e) {
        e.printStackTrace();
      }

      @Override public void onResponse(Call call, Response response) throws IOException {
        try (ResponseBody responseBody = response.body()) {
          if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

          Headers responseHeaders = response.headers();
          for (int i = 0, size = responseHeaders.size(); i < size; i++) {
            System.out.println(responseHeaders.name(i) + ": " + responseHeaders.value(i));
          }

          System.out.println(responseBody.string());
        }
      }
    });

如何使用OKHttp进行异步调用和回调？
