You may want to check C++ REST SDK (codename "Casablanca"). http://msdn.microsoft.com/en-us/library/jj950081.aspx

With the C++ REST SDK, you can more easily connect to HTTP servers from your C++ app.

Usage example:

#include 
#include 

using namespace web::http;                  // Common HTTP functionality
using namespace web::http::client;          // HTTP client features

int main(int argc, char** argv) {
    http_client client("http://httpbin.org/");

    http_response response;
    // ordinary `get` request
    response = client.request(methods::GET, "/get").get();
    std::cout << response.extract_string().get() << "\n";

    // working with json
    response = client.request(methods::GET, "/get").get();
    std::cout << "url: " << response.extract_json().get()[U("url")] << "\n";
}

The C++ REST SDK is a Microsoft project for cloud-based client-server communication in native code using a modern asynchronous C++ API design.
