本文整理了Java中com.android.volley.Request类的一些代码示例，展示了Request类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Request类的具体详情如下：
包路径：com.android.volley.Request
类名称：Request

Request介绍

[英]Base class for all network requests.
[中]所有网络请求的基类。

代码示例

@Override
  public HttpResponse performRequest(Request<?> request, Map<String, String> additionalHeaders)
      throws AuthFailureError {
    mLastUrl = request.getUrl();
    mLastHeaders = new HashMap<String, String>();
    if (request.getHeaders() != null) {
      mLastHeaders.putAll(request.getHeaders());
    }
    if (additionalHeaders != null) {
      mLastHeaders.putAll(additionalHeaders);
    }
    try {
      mLastPostBody = request.getBody();
    } catch (AuthFailureError e) {
      mLastPostBody = null;
    }
    return mResponseToReturn;
  }
}
