本文整理了Java中java.net.HttpURLConnection.getErrorStream()方法的一些代码示例，展示了HttpURLConnection.getErrorStream()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。HttpURLConnection.getErrorStream()方法的具体详情如下：
包路径：java.net.HttpURLConnection
类名称：HttpURLConnection
方法名：getErrorStream

HttpURLConnection.getErrorStream介绍

[英]Returns an input stream from the server in the case of an error such as the requested file has not been found on the remote server. This stream can be used to read the data the server will send back.
[中]在远程服务器上未找到请求的文件等错误的情况下，从服务器返回输入流。此流可用于读取服务器将发回的数据。

代码示例

@Override
public InputStream getBody() throws IOException {
  InputStream errorStream = this.connection.getErrorStream();
  this.responseStream = (errorStream != null ? errorStream : this.connection.getInputStream());
  return this.responseStream;
}

HttpURLConnection httpConn = (HttpURLConnection)_urlConnection;
InputStream _is;
if (httpConn.getResponseCode() < 400) {
  _is = httpConn.getInputStream();
} else {
   /* error from server */
  _is = httpConn.getErrorStream();
}
