我正在尝试使用 HTTP POST 请求将我正在开发的游戏的文件发送到该游戏的网站。当我使用 HTML 页面上的表单发送文件时,它工作正常。但是,我一直无法在游戏中模拟同样的事情。我收到一个 200 的响应代码,表示请求成功,但是,上传脚本表示它收到了 GET 请求,并且 $_FILES 和 $_POST 数组为空。我在 Wireshark 中查看了 HTML 表单的 POST 和游戏的 POST 的输出,但无法检测到两者之间有任何有意义的差异。 (如果我知道如何准确复制 HTML 表单的 POST 方法,我会的,但我认为那不可能。)
无论如何,这是我用来发送它的代码。谢谢!

最佳答案
我之前试图回答这个问题,但我想它没有通过。反正我觉得挺傻的。它现在工作得很好。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”。我不知道为什么这会阻止它工作 - 特别是考虑到我的上传脚本/leaderboard/upload_file.php 正在执行。这不像流量没有到达服务器。奇怪。
无论如何,感谢大家的帮助!
