Question

我有一个本地的websphere服务器，我想用来从网页中提取内容。当我向服务器发出get请求时，我收到了很大的错误。它似乎是通过从连接获取输入流来触发的。

这是我的代码（实际上并没有尝试从谷歌中读取它只是一个占位符）

URL url = new URL("https://google.ca");

URLConnection conn = url.openConnection();

BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));

只有在我进入第三行时才会中断，我收到此错误

可能是防火墙问题，google.ca的TCP connect（）超时了。您可能会遇到相同的结果如果您可以在同一系统上的应用程序服务器之外进行测试。
