CURLOPT_MIMEPOST explained

Name

CURLOPT_MIMEPOST - send data from mime structure

Synopsis

#include <curl/curl.h>
 
curl_mime *mime;
 
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MIMEPOST, mime);

Description

Pass a mime handle previously obtained from curl_mime_init.

This setting is supported by the HTTP protocol to post forms and by the SMTP and IMAP protocols to provide the email data to send/upload.

This option is the preferred way of posting an HTTP form, replacing and extending the CURLOPT_HTTPPOST option.

When setting CURLOPT_MIMEPOST to NULL, libcurl resets the request type for HTTP to the default to disable the POST. Typically that would mean it is reset to GET. Instead you should set a desired request method explicitly.

Protocols

HTTP, SMTP, IMAP.

Example

 curl_mime *multipart = curl_mime_init(handle);
 curl_mimepart *part = curl_mime_addpart(multipart);
 curl_mime_name(part, "name");
 curl_mime_data(part, "daniel", CURL_ZERO_TERMINATED);
 part = curl_mime_addpart(multipart);
 curl_mime_name(part, "project");
 curl_mime_data(part, "curl", CURL_ZERO_TERMINATED);
 part = curl_mime_addpart(multipart);
 curl_mime_name(part, "logotype-image");
 curl_mime_filedata(part, "curl.png");
 
 /* Set the form info */
 curl_easy_setopt(handle, CURLOPT_MIMEPOST, multipart);
 
 curl_easy_perform(handle); /* post away! */
 
 curl_mime_free(multipart); /* free the post data */
