来自一个HttpURLConnection的多个请求 [英] several requests from one HttpURLConnection

问题描述

如何使用Java在一个HttpURLConnection中执行几个请求?

How can I do several request in one HttpURLConnection with Java?

 URL url = new URL("http://my.com");
 HttpURLConnection connection = (HttpURLConnection)url.openConnection();
 HttpURLConnection.setFollowRedirects( true );
 connection.setDoOutput( true );
 connection.setRequestMethod("GET"); 

 PrintStream ps = new PrintStream( connection.getOutputStream() );
 ps.print(params);
 ps.close();
 connection.connect();
 //TODO: do next request with other url, but in same connection

谢谢.

推荐答案

来自Javadoc:

每个HttpURLConnection实例用于发出单个请求.

Each HttpURLConnection instance is used to make a single request.

该对象显然不打算重复使用.

The object apparently isn't meant to be re-used.

除了一点内存混乱和效率低下外，为您要发出的每个请求打开一个HttpURLConnection并没有什么大问题.但是，如果您想要大规模高效的网络IO，最好使用专门的库，例如 Apache HttpClient .

Aside from a little memory thrashing and inefficiency, there's no big problem with opening one HttpURLConnection for every request you want to make. If you want efficient network IO on a larger scale, though, you're better off using a specialized library like Apache HttpClient.
