So my current employer wants our existing MFC application to interface with some web services exposed by our new website (sorry, need to stay hush-hush about it at the moment). Now, while the MFC side of things is turning out to be a bitch, I threw together some classes to make life easier for me. The source is here.
CppHttp.h is a simple class to do GET and POST requests through. Currently, it does NOT do multi-part requests, but I promise to update this when I get to that. To consume the responses, I'm using TinyXML. I looked at some other libraries, including using the MsXml stuff, but they were WAY overboard what I needed. I included a sample class that calls a stock market thing I found on xmethods.net. The Find method in there is particularly useful when getting, say, a DataTable back and wanting to go straight to the nodes.
Anyway, hope this is useful. Let me know your thoughts.
