Ahojte,
mam v premennej ulozene binarne data obrazku a potrebujem pomocou php vytvorit http request na server pomocou jeho jeho api, pricom budem posielat ten obrazok. Content-type musi byt multipart/form-data . Cize potrebujem v podstate v phpcku vytvorit request asi taky, aky vytvori prehliadac ked potvrdim form s atributom enctype="multipart/form-data".
Viete niekto, ako na to ? Dik

Toto som zatial vyskusal podla toho, co som vycital z dokumentacie. Myslel som si, ze mi bude treba binarne data ale teraz poskytujem ten obrazok ako resource:

Kód:

$url = 'tu_mam_web_api_url';
$input = fopen('delfin.jpg','r');        
$header = array('Content-Type: multipart/form-data');
$resource = curl_init();
curl_setopt($resource, CURLOPT_URL, $url);
curl_setopt($resource, CURLOPT_USERPWD, "meno:heslo");
curl_setopt($resource, CURLOPT_HTTPAUTH, CURLAUTH_ANYSAFE);
curl_setopt($resource, CURLOPT_HTTPHEADER, $header);
curl_setopt($resource, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($resource, CURLOPT_BINARYTRANSFER, true );
curl_setopt($resource, CURLOPT_INFILESIZE, 61631);
curl_setopt($resource, CURLOPT_INFILE, $input);
$result = curl_exec($resource);
curl_close($resource);
var_dump($result);

Ja este neviem ako presne ma vobec vyzerat odpoved zo servera, no zatial mi to hadze len http status 405, chyba: The specified HTTP method is not allowed for the requested resource ().
zrejme musim ten obrazok posielat nejak inak. Ako som napisal, potrebujem asi taky request, ako ked prehliadac odosiela ten obrazok z formu s atributom enctype="multipart/form-data". Ja tym requestom prilis dobre nerozumiem.

Mam to vyriesene. Ak chcete poslat post request s typom multipart/form-data s obrazkom v poli files:

Kód:

    $url = "cesta_k_serveru";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_VERBOSE, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_USERPWD, "meno:heslo");
    curl_setopt($ch, CURLOPT_POST, true);
    $post = array(
        "uploadedFile"=>"@/cesta/k/suboru/delfin.jpg;type=image/jpeg",
    );
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    $result = curl_exec($ch);
    curl_close ($ch);

Ak post request s typom multipart/form-data s obrazkom v poli post ako binarne data (nie som si isty, ci je toto spravne):

Kód:

$localFile = 'delfin.jpg';
$ch = curl_init();
$fp = fopen($localFile, 'r');
$url = "cesta_k_serveru";
curl_setopt($ch, CURLOPT_USERPWD, "meno:heslo");
curl_setopt($ch, CURLOPT_URL, $url);
$data = 'POST tu_cesta_na_serveri HTTP/1.0
Host: nieco.com
Content-type: multipart/form-data, boundary=AaB03x
Content-Length: '.filesize($localFile).'

--AaB03x
content-disposition: form-data; name="delfin.jpg"; filename="delfin.jpg"
Content-Type: image/jpeg
Content-Transfer-Encoding: binary

'.file_get_contents('delfin.jpg').'
--AaB03x--';
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
curl_close($ch);

Ak put request:

Kód:

$url = "cesta_k_serveru";
$localFile = 'delfin.jpg';
$fp = fopen($localFile, 'r');
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERPWD, "meno:heslo");
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data"));
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 86400);
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localFile));
$result = curl_exec($ch);
curl_close ($ch);
