Problems with implementing HTTP/HTTPS post in C/C ++

It is really unpleasant to use Microsoft's set of things. Writing a Small HTTP/HTTPS post function is all crazy.

Connection, send, and close.

The API httpsendrequest is used for sending, but the body of this method (that is, the 4th parameters must be multi-Char), so you are currently using Unicode, it must be converted to multi-Char.

What are the consequences of not converting? The result is that the post data is incomplete. In addition, post data only has one letter.

Unfortunately, msdn does not explain this API clearly. This will make people do not know the reason.

Continue to think about the fact that MFC actually encapsulates the underlying API. Does the sendrequest of chttpfile have a similar problem? The answer is yes. The solution is described above.
