c socket http get request code example
Example: how to make a get request over socket c
char sendline[MAXLINE + 1], recvline[MAXLINE + 1];
char* ptr;
size_t n;
/// Form request
snprintf(sendline, MAXSUB,
"GET %s HTTP/1.0\r\n" // POST or GET, both tested and works. Both HTTP 1.0 HTTP 1.1 works, but sometimes
"Host: %s\r\n" // but sometimes HTTP 1.0 works better in localhost type
"Content-type: application/x-www-form-urlencoded\r\n"
"Content-length: %d\r\n\r\n"
"%s\r\n", page, host, (unsigned int)strlen(poststr), poststr);
/// Write the request
if (write(sockfd, sendline, strlen(sendline))>= 0)
{
/// Read the response
while ((n = read(sockfd, recvline, MAXLINE)) > 0)
{
recvline[n] = '\0';
if(fputs(recvline, stdout) == EOF)
{
printf("fputs() error\n");
}
/// Remove the trailing chars
ptr = strstr(recvline, "\r\n\r\n");
// check len for OutResponse here ?
snprintf(OutResponse, MAXRESPONSE,"%s", ptr);
}
}
