客戶端服務器Visual C++中的通信套接字編程

下面的代碼創建一個服務器與客戶端進行通信。此代碼可以在HTTP上正常工作，但在HTTPS中無法正常工作。建議一個方法或網絡功能需要包含在ssl上正常工作。客戶端服務器Visual C++中的通信套接字編程

Socket是一個比http和https-http和https運行在頂層的更低級別的協議。您使用套接字的評價應該可以與https協同工作 - 但您將獲得原始的加密數據 - 這可能不是您想要的。

我建議你看看使用更高級別的類 - 比如WinInet：http://msdn.microsoft.com/en-us/library/3w2azyt6.aspx
