Post a not empty file to Dspace with Curl - json

Question

I am posting a file to dspace through dspace api, I am doing this with an action in php. With postman I send a form-data with the file, filename, bitstream id and token.
I am getting the temp file path with $_FILES and sending it by postfields curl option, but the file uploads empty, or with weird data, without its content.
public function actionSubirBitstream()
{
if (Yii::$app->request->isPost) {
$body = $_POST;
$prefijo = '/rest/items/';
$host = ConfiguracionDspace::find()->where("clave='host'")->one()->valor;
$puerto = ConfiguracionDspace::find()->where("clave='puerto'")->one()->valor;
$token = $body['token'];
$id = $body['id'];
$final = '/bitstreams';
$name = $body['name'];//nombre del archivo sin espacios
$params = "?name=$name";
$url = $host . ':' . $puerto . $prefijo . $id . $final . $params;
$file = $_FILES['file']['tmp_name'];
//$path = $body['path'];
//$file = new CURLFILE("$path");
$headers = array("Content-Type: application/json", 'Accept: application/json', "rest-dspace-token: " . $token);
$curl = curl_init($url);
$options = array(
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => array('file'=> $file,'name' => $name),
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => $headers
);
curl_setopt_array($curl, $options);
$response = curl_exec($curl);
curl_close($curl);
return $response;
}
}

Answer 1

CURLOPT_CUSTOMREQUEST => 'POST',
CURLOPT_POSTFIELDS => array('photo'=> new CURLFILE('/C:/Users/pfile3.jpeg'),'name' => $name),
this is the example of uploading a file with form key as photo and another key name
in your screen shot you have id and token in form data but in code its not inside POSTFIELDS
in postman you can generate equalent code of request in any language , try generating the PHP equalent code and see if it works:
To do this just click code link under the request url after saving the request

Answer 2

I already post the file by the $_FILE variable, But what I needed to do was to use CURLFILE to create a new file, and give it the temp path of the file in the server
$file = $_FILES['file']['tmp_name'];
and this in the postfields
CURLOPT_POSTFIELDS => array('file'=> new CURLFile("$file"),'name' => $name),
Thanks for the help friends
Here the code:
public function actionSubirBitstream()
{
if (Yii::$app->request->isPost) {
$body = $_POST;
$prefijo = '/rest/items/';
$host = ConfiguracionDspace::find()->where("clave='host'")->one()->valor;
$puerto = ConfiguracionDspace::find()->where("clave='puerto'")->one()->valor;
$token = $body['token'];
$id = $body['id'];
$final = '/bitstreams';
$name = $body['name'];//nombre del archivo sin espacios
$params = "?name=$name";
$url = $host . ':' . $puerto . $prefijo . $id . $final . $params;
$file = $_FILES['file']['tmp_name'];
//$path = $body['path'];
//$file = new CURLFILE("$path");
$headers = array("Content-Type: application/json", 'Accept: application/json', "rest-dspace-token: " . $token);
$curl = curl_init($url);
$options = array(
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => array('file'=> new CURLFile("$file"),'name' => $name),
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => $headers
);
curl_setopt_array($curl, $options);
$response = curl_exec($curl);
curl_close($curl);
return $response;
}
}
The posted files with the rigth size(finally)
The form data I send by Postman, no need to use the field path
