通过Java中的IP地址将HTTP GET请求发送到目标

Question

I have an Apache web server launched on another computer in my local network, that have a .php file in its root folder, so I can send my requests from browser using addresses like "192.168.1.5/connect.php?param1=value1&param2=value2". I really need to do that from my java code (by using HttpUrlConnection), but by some reason it works only with url, not with the IP address, I mentioned above. Is there a way to make it work with IP instead of url?

Answer 1

HttpUrlConnection可以完美地用于主机名HTTP连接和IP地址HTTP连接：

HttpURLConnection conn = (HttpURLConnection) new URL("http://192.168.1.5/connect.php?param1=value1&param2=value2").openConnection();

Answer 2

Please read and understand the URL syntax as described here https://www.ietf.org/rfc/rfc1738.txt

Having said that, the http scheme allows hostnames or ip addresses.

http://192.168.1.5/connect.php?param1=value1&param2=value2

is a valid URL.
