Split String by Carriage Return C

Question

I am having a problem where I am trying to split an HTTP request by a carriage return for a web proxy. The request does not seem to split.

Here is an example request: GET /pub/WWW/TheProject.html HTTP/1.1\r\nHost: www.w3.org\r\n

My attempt is:

char* split_request;
split_request = strtok(request, "\r\n");

But it never gets split? I am not sure what I am missing. It seems to split when I am using wget or the browser to test the web proxy, but doesn't with telnet.

Answer 1

Are you doing this way?

#include <stdio.h>
#include <string.h>

int main (void)
{
    char str[] = "GET /pub/WWW/TheProject.html HTTP/1.1\r\nHost: www.w3.org\r\n";
    char* pch = NULL;

    pch = strtok(str, "\r\n");

    while (pch != NULL)
    {
        printf("%s\n", pch);
        pch = strtok(NULL, "\r\n");
    }
    return 0;
}

Output:

GET /pub/WWW/TheProject.html HTTP/1.1   
Host: www.w3.org
