前言

winhttp与winInet主要区别有以下几点：

1. winHttp被设计为主要应用再服务器端应用程序的场景下，让服务器端应用程序访问HTTP服务器。winINet被设计为一个HTTP客户端平台，用来交互式桌面应用程序。服务器端应用程序要求HTTP客户端服务使用winHttp，客户端则使用WInet。
2. WinHTTP也可以用于系统服务以及基于HTTP的客户端应用，但是对于那种需要使用到FTP协议，cookie保存，缓存cache，自动证书对话框处理，IE兼容，或者下载平台支持的应用则应该使用WinINet。
3. WinINet是WinHTTP的一个超集。按照Microsoft的说法，在这两者之间做选择的时候最好选择WinINet，除非你是计划运行一个服务器或者是一个能够仿造请求及session隔离的类似于服务器的进程。

一、winInet接口

官网地址：https://learn.microsoft.com/zh-cn/windows/win32/wininet/portal

二、客户端介绍

该客户端工程基于VS2019下，使用winInet进行实现。主要功能是通过Get和Post与服务器进行交互，认证采用了basic认证。服务端实现程序可以参考我的另一篇博客：https://blog.csdn.net/linyibin_123/article/details/129562224。

三、核心代码

HttpClient.h

#pragma onceint myprint(const char* msg, ...);class HttpClient

};
