出于某种原因，我不知道POST请求无效。我很确定问题出在POST字符串"POST /profile.php HTTP/1.1\r\nid=2323\r\nContent-Length: \r\n\r\n"上。 GET请求正常运行，但POST请求无效。
我使用TLS VER 1.0通过端口443连接到服务器
这里是我从服务器获得的错误代码。编辑：我正在尝试编辑此帖子以对其进行修复，它告诉我我的帖子主要是代码，但我希望不再是。

代替发出POST请求，您可以只使用GET请求并执行此操作
"GET /profile.php?id=2323 HTTP/1.1\r\nConnection: close\r\n\r\n"
主要取决于您要连接的服务器，因此，如果这不起作用，请尝试使用HTTP v1.0
"GET /profile.php?id=2323 HTTP/1.0\r\nConnection: close\r\n\r\n"
如果仍然不起作用，则可能必须指定主机，主要是在您尝试从看起来像https://en30.picwebsite.com的网站上获取图像时>
"GET /profile.php?id=2323 HTTP/1.1\r\nHost: en30.picwebsite.com\r\nConnection: close\r\n\r\n"
同时尝试HTTP v1.0和v1.1
如果所有方法均无效，请确保您正在使用SSL / TLS进行连接。如果您愿意，请尝试使用一个简单的主页GET请求"GET / HTTP/1.1\r\nConnection: close\r\n\r\n"以及HTTP v1.0和v1.1
如果还是不行，那可能是您的Socket / TLS实现或服务器出现问题。
