无法获得HTTP POST请求以正常工作 [英] Can't get HTTP POST request to work properly
问题描述
我正在尝试使用HTTP POST请求将正在处理的游戏的文件发送到游戏的网站.当我使用HTML页面上的表单发送文件时，它可以正常工作.但是，我无法在游戏中模拟相同的事物.我收到的响应代码为200，表明请求已成功执行，但是，上载脚本表明它已接收到GET请求，并且$ _FILES和$ _POST数组为空.我已经在Wireshark中查看了HTML表单的POST和游戏的POST的输出，但是无法检测到两者之间的任何有意义的区别. (如果我知道如何精确地复制HTML表单的POST方法，那么可以，但是我认为这是不可能的.)
I'm trying to send a file from a game I'm working on to the game's website using an HTTP POST request. When I send the file using a form on an HTML page, it works fine. However, I have been unable to simulate the same thing inside the game. I am receiving a response code of 200 indicating that the request went successfully, however, the upload script indicates that it received a GET request, and the $_FILES and $_POST arrays are empty. I have looked at the output of both the HTML form's POST and the game's POST in Wireshark, but have been unable to detect any meaningful differences between the two. (If I knew how to duplicate the HTML form's POST method exactly, I would, but I don't think that's possible.)
无论如何，这是我用来发送它的代码.谢谢！

推荐答案
我尝试早些回答，但我想它没有通过.无论如何，我觉得很傻.现在工作正常.它不起作用的原因是因为我将InternetOpen()的第二个参数设置为"wrackgame.com"，而不是"www.wrackgame.com".我不知道为什么会阻止它运行-特别是考虑到我的上传脚本/leaderboard/upload_file.php正在执行.并不是说流量没有到达服务器.奇怪.
I tried to answer this earlier, but I guess it didn't get through. Anyway, I feel pretty silly. It's working perfectly now. The reason it wasn't working is because I had the second parameter of InternetOpen() as "wrackgame.com", instead of "www.wrackgame.com". I have no idea why that prevented it from working - especially considering that my upload script, /leaderboard/upload_file.php, was being executed. It's not like the traffic wasn't reaching the server. Strange.
无论如何，谢谢大家的帮助！
