CURLINFO_CONTENT_TYPE explained

NAME

CURLINFO_CONTENT_TYPE - get Content-Type

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_TYPE, char **ct);

DESCRIPTION

Pass a pointer to a char pointer to receive the content-type of the downloaded object. This is the value read from the Content-Type: field. If you get NULL, it means that the server didn't send a valid Content-Type header or that the protocol used doesn't support this.

The ct pointer will be NULL or pointing to private memory you MUST NOT free it - it gets freed when you call curl_easy_cleanup on the corresponding CURL handle.

PROTOCOLS

HTTP(S)

EXAMPLE

CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
 
  res = curl_easy_perform(curl);
 
  if(!res) {
    /* extract the content-type */
    char *ct = NULL;
    res = curl_easy_getinfo(curl, CURLINFO_CONTENT_TYPE, &ct);
    if(!res && ct) {
      printf("Content-Type: %s\n", ct);
    }
  }
  curl_easy_cleanup(curl);
}
