HttpURLConnection如何输出全部服务器响应结果

可以通过以下步骤来输出全部服务器响应结果：

1. 获取HttpURLConnection对象的输入流，即服务器响应内容的流：

InputStream inputStream = httpURLConnection.getInputStream();

2. 使用BufferedReader读取输入流中的内容，并将其输出到控制台或文件中：

BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
String line;
while ((line = bufferedReader.readLine()) != null) {
    System.out.println(line);
}

3. 关闭输入流和连接：

bufferedReader.close();
inputStream.close();
httpURLConnection.disconnect();

完整代码示例：

URL url = new URL("http://www.example.com");
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setRequestMethod("GET");
InputStream inputStream = httpURLConnection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
String line;
while ((line = bufferedReader.readLine()) != null) {
    System.out.println(line);
}
bufferedReader.close();
inputStream.close();
httpURLConnection.disconnect();
