Yes, but not with wxHTTP. CURL is very useful, full featured, easy and works well with wxWidgets. There is also a wx wrapper called wxCurl, but i can't testify to it's usefulness as i just use CURL directly.

is curl platform independent?

Yes, I'm not sure every platform it builds on but I've used it fine on linux and msw.

I have a wxHTTPPost class

Also, wxCurl is pretty good - and easier than using curl directly (as I've done both approaches)

Hope this helps

i tried it now with curl directly - its really easy to use, but it looks for me like i made an error. maybe you find quickly whats wrong here.

i try to upload an image with curl - by using a php file.

curl code:

Code: Select all

	CURL *easyhandle = curl_easy_init(); 
	curl_easy_setopt( easyhandle, CURLOPT_URL, "http://url.com/upload.php" );
char *error = new char[CURL_ERROR_SIZE];
curl_easy_setopt(easyhandle, CURLOPT_ERRORBUFFER, error);

	curl_httppost *post = NULL;
	curl_httppost *last = NULL;
	curl_slist *headers = NULL;
	
	headers = curl_slist_append( headers, "Content-Type: image/png");

	curl_formadd( &post, &last, CURLFORM_COPYNAME, "user", CURLFORM_COPYCONTENTS, "990", CURLFORM_END );
	curl_formadd( &post, &last, CURLFORM_COPYNAME, "pic", CURLFORM_FILECONTENT, "unknown.png", CURLFORM_CONTENTHEADER, headers, CURLFORM_END);

	curl_easy_setopt( easyhandle, CURLOPT_HTTPPOST, post );
	curl_easy_perform( easyhandle );

	curl_formfree( post ); 
	curl_slist_free_all( headers );

the php code:

Code: Select all

$fp = fopen( $_POST['user'].".png", "wb+" );
fwrite( $fp, $_POST['avatare'] );
fclose($fp);

data is uploaded and everything works fine, except that the uploaded data is not the same as the original one - the image gets corrupted. maybe you have an idea. kind regards
