如何从Java代码调用PHP脚本？

正如标题所示……当用户单击Java Swing应用程序中的按钮时,我尝试使用以下代码执行PHP脚本：

URL url = new URL( "http://www.mywebsite.com/my_script.PHP" );
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.connect();

但没有任何反应……有什么不对吗？

解决方法:

我想你错过了下一步,例如：

InputStream is = conn.getInputStream();

HttpURLConnection基本上只打开连接上的套接字,以便做一些你需要做的事情,比如调用getInputStream()或更好的仍然是getResponseCode()

URL url = new URL( "http://google.com/" );
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
if( conn.getResponseCode() == HttpURLConnection.HTTP_OK ){
    InputStream is = conn.getInputStream();
    // do something with the data here
}else{
    InputStream err = conn.getErrorStream();
    // err may have useful information.. but Could be null see javadocs for more information
}
