WebClient in C++

Question

I'm writing a program that needs to be able to read in HTML source code into a string.

I've read about WebClient for C# but I need to write my program in C++ and I'm not sure how to do that (I've never used WebClient before).

Can anyone give me a simple C++ example program showing me how to get HTML source code into a string using WebClient? (or any better method)

Thanks.

What do you have to do with the HTML once you have it in memory? Is it really just reading it, or do you need to parse the structure? — john.pavan, Mar 03 '13 at 13:29
I'm reading it into a string and searching through the string for numbers (but i'm fine with that part) its just getting the source code into the string that i don't know how to do — user2054823, Mar 03 '13 at 13:30
Straight off the web into a string, or straight off the web into a file — user2054823, Mar 03 '13 at 13:55
2 people have already answered how to go from a file into ram, you can use curl to get it from the web into a file: http://curl.haxx.se/docs/httpscripting.html — john.pavan, Mar 03 '13 at 13:57

See this page, A Fully Featured Windows HTTP Wrapper in C++:

http://www.codeproject.com/Articles/66625/A-Fully-Featured-Windows-HTTP-Wrapper-in-C

Sample code from that page, looks like what you want:

void ProgressTest(void)
{
    // Set URL and call back function.
    WinHttpClient client(L"http://www.codeproject.com/", ProgressProc);
    client.SendHttpRequest();
    wstring httpResponseHeader = client.GetResponseHeader();
    wstring httpResponseContent = client.GetResponseContent();
}

I don't know what webclient for c# is. To read a file into a string-:

 std::ifstream ifs("webpage.html");
 std::string str;
 str.assign((std::istreambuf_iterator<char>(ifs)),
            (std::istreambuf_iterator<char>()));

as the question title suggests, the op wants to access the file using a http request, hence the need to get a webclient. – diego.martinez May 29 '18 at 15:40
