How do you make a HTTP request with C++?

Question

Is there any way to easily make a HTTP request with C++? Specifically, I want to download the contents of a page (an API) and check the contents to see if it contains a 1 o

Answer 1

You can use ACE in order to do so:

#include "ace/SOCK_Connector.h"

int main(int argc, ACE_TCHAR* argv[])
{
    //HTTP Request Header
    char* szRequest = "GET /video/nice.mp4 HTTP/1.1\r\nHost: example.com\r\n\r\n"; 
    int ilen = strlen(szRequest);

    //our buffer
    char output[16*1024];

    ACE_INET_Addr server (80, "example.com");
    ACE_SOCK_Stream peer;
    ACE_SOCK_Connector connector;
    int ires = connector.connect(peer, server);
    int sum = 0;
    peer.send(szRequest, ilen);
    while (true)
    {
        ACE_Time_Value timeout = ACE_Time_Value(15);
        int rc = peer.recv_n(output, 16*1024, &timeout);
        if (rc == -1)
        {
            break;
        }
        sum += rc;
    }
    peer.close();
    printf("Bytes transffered: %d",sum);

    return 0;
}
