c ++ winhttp / wininet包装器发布表单和上传文件没有mfc / atl [英] c++ winhttp/wininet wrapper to post forms and upload files without mfc/atl

问题描述

有人可能有人指向我一个winhttp / wininet基于c ++包装，这将不需要mfc / atl？所以我可以在MSVC express中使用它。

我想通过HTML形式使用GET，POST和上传文件。 p>

我已经在codeproject.com中检查过几个，但是找不到合适的包装器。

帮助我？

解决方案

在这里，我给你一个让你开始。如果你使用MSVC，你应该学会如何通过dll的挖掘和找到导出的功能。 DLL导出查看器是我用于此目的。你就需要找到WININET。 dll位于您的计算机上，并相应地更改代码。我希望这有帮助。所以这里是我的WinInetRTW类（运行时包装）。

could somebody point me to a winhttp/wininet based c++ wrapper which would not require mfc/atl? So that I might get it to work in MSVC express.

I'd like to be able to use GET, POST and upload files too through HTML-form.

I've checked several in codeproject.com but had trouble finding a suitable wrapper.

Is there something that could help me?

解决方案

Here I made you one to get you started. If you are using a MSVC you should learn how to dig down through dll's and find exported functions. DLL Export Viewer is what I used for this. You'll need to find where wininet.dll is located on your machine and alter the code accordingly. I hope this helps. So here is my WinInetRTW class (Run Time Wrapper).
