Post function donnot have the implement which only has path, header

[fengmao31]

I post the request to server microsoft azure token server to access the tts service. But I find the source code have no implement which only has path, header. I need the header part. when I set body or param nulptr, I find it throw a error.
of course, it is easy to make a new implement function of Post similar to other implement. But I donnot want to change the source code to take the risk to maintain a different version from the public git repository.

I have the same problem.

do not use nullptr, use empty string e.g. std::string()

@fengmao31, I added the Post method. (Also @PixlRainbow's comment should work.)
