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 did not send a valid Content-Type header or that the protocol used does not 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(3) on the corresponding CURL handle.

PROTOCOLS

HTTP(S)

EXAMPLE

CURL *curl = curl_easy_init();
if(curl) {


  curl_easy_setopt(curl, CURLOPT_URL, "https://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);
}
