Hello,
I adapted the sample program postit2.c and am trying to do
a simple post. I am using tcpdump to examine the
communication to the web server, and everything looks good
except the HTTP headers. I specifically set 3 headers but
they do not appear when I perform the POST. Any ideas how
to do this? It seems very simple, but I haven't been able
to figure it out. Here is the source code below.
Thanks,
Tim.
#include <stdio.h>
#include <string.h>
#include <curl/curl.h>
#include <curl/types.h>
#include <curl/easy.h>
int main(int argc, char *argv[])
{
CURL *curl;
CURLcode res;
struct curl_httppost *formpost=NULL;
struct curl_httppost *lastptr=NULL;
struct curl_slist *headerlist=NULL;
curl_global_init(CURL_GLOBAL_ALL);
/* Fill in the file upload field */
curl_formadd(&formpost,
&lastptr,
CURLFORM_COPYNAME, "sendfile",
CURLFORM_FILE, "postit2.c",
CURLFORM_END);
/* Fill in the filename field */
curl_formadd(&formpost,
&lastptr,
CURLFORM_COPYNAME, "filename",
CURLFORM_COPYCONTENTS, "postit2.c",
CURLFORM_END);
/* Fill in the submit field too, even if this is rarely
needed */
curl_formadd(&formpost,
&lastptr,
CURLFORM_COPYNAME, "submit",
CURLFORM_COPYCONTENTS, "send",
CURLFORM_END);
curl = curl_easy_init();
headerlist = curl_slist_append(headerlist,
"FILE_SIZE=3130");
headerlist = curl_slist_append(headerlist,
"FILE_NAME=postit2.c");
headerlist = curl_slist_append(headerlist, "ID=123");
headerlist = curl_slist_append(headerlist, "Expect:");
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL,
"http://myserver.com:19602/sec-cgi/receiver.cgi";);
curl_easy_setopt(curl, CURLOPT_HTTPHEADER,
headerlist);
curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost);
res = curl_easy_perform(curl);
if (res != CURLE_OK)
printf("CURL error, trying to perform the
http post.\n");
/* always cleanup */
curl_easy_cleanup(curl);
/* then cleanup the formpost chain */
curl_formfree(formpost);
/* free slist */
curl_slist_free_all (headerlist);
}
return 0;
}
