到底该用哪个接口，微软这么说，api方式：功能齐全，不过调用复杂些；com接口，调用简单，属于一个封装，有部分功能缺失。https://msdn.microsoft.com/zh-cn/library/aa383158(v=vs.85).aspx

	C/C++ API	COM interface
Advantages	Responses can be processed in chunks, which is more efficient. POST operations can also be processed in chunks, speeding processing time. AutoProxy support. Access to the full feature set of WinHTTP. Binary data can easily be handled.	Creating an application is easy and requires fewer lines of code than the C/C++ API. The interface can be used by scripting languages.
Disadvantages	Processing is more complex. The C/C++ API requires more steps than the COM interface to perform the same actions. Setting up a request takes more code.	The COM interface does not provide access to the full feature set of WinHTTP. It is difficult to handle binary data types in some scripting languages, such as VBScript and JScript. The COM interface does not support AutoProxy. Applications must use the COM APARTMENT_THREADED model. Before a response can begin being processed, the entire response must first be received and buffered.
