Binary data parameter in cURL

Question

I need to send a binary data parameter via cURL in php.
This is the command: curl -D - -u user:password -X PUT -H "Content-Type: text/plain" --data-binary "data-id=2010-10-01_15-15-53" https://someurl . This works in the console, now I have to do it in php.

This is the code I have:

  $this->_curl = curl_init(); curl_setopt($this->_curl, CURLOPT_USERPWD, $this->_loginUser . ":" . $this->_loginPassword); curl_setopt($this->_curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($this->_curl, CURLOPT_HEADER, 1); curl_setopt($this->_curl, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($this->_curl, CURLOPT_TIMEOUT, 30); curl_setopt($this->_curl, CURLOPT_URL, $this->_serviceUrl);//https://someurl curl_setopt($this->_curl, CURLOPT_HTTPHEADER, array('Content-Type: text/plain')); curl_setopt($this->_curl, CURLOPT_CUSTOMREQUEST, 'PUT'); curl_setopt($this->_curl, CURLOPT_POSTFIELDS, array('data-id' => $dataId));//d'2010-10-01_15-15-53' $response = curl_exec($this->_curl); //$response = HTTP/1.1 201 Created curl_close($this->_curl); 

the call is accepted by the server, but it does not recognize the data-id parameter:

The data identifier property is not defined in the trigger 2010-10-01_15-15-53

Any idea what I am missing?

Answer 1

You need to convert the string to stream first.

You can simply do this with this piece of code.

 $YourString = 'data-id=2010-10-01_15-15-53'; $stream = fopen('php://memory','r+'); fwrite($stream, $YourString ); $dataLength = ftell($stream); rewind($stream); 

Then, having your own stream, you can send it using curl.

 $curl = curl_init(); curl_setopt_array( $curl, array( CURLOPT_CUSTOMREQUEST => 'PUT' , CURLOPT_URL => 'https://someurl' , CURLOPT_HTTPHEADER => array( 'Content-Type: text/plain' ) , CURLOPT_RETURNTRANSFER => 1 // means output will be a return value from curl_exec() instead of simply echoed , CURLOPT_TIMEOUT => 15 // max seconds to wait , CURLOPT_FOLLOWLOCATION => 0 // don't follow any Location headers, use only the CURLOPT_URL, this is for security , CURLOPT_FAILONERROR => 0 // do not fail verbosely fi the http_code is an error, this is for security , CURLOPT_SSL_VERIFYPEER => 1 // do verify the SSL of CURLOPT_URL, this is for security , CURLOPT_VERBOSE => 0 // don't output verbosely to stderr, this is for security , CURLOPT_INFILE => $stream , CURLOPT_INFILESIZE => $dataLength , CURLOPT_UPLOAD => 1 ) ); $response = curl_exec($curl); $http_code = curl_getinfo($curl, CURLINFO_HTTP_CODE); curl_close($curl); echo($response.'<br/>'); echo($http_code.'<br/>'); 

That should work. The lines that will help you are highlighted below:

CURLOPT_INFILE => $ stream

CURLOPT_INFILESIZE => $ dataLength

CURLOPT_UPLOAD => 1

Answer 2

Why do you want to pass plain text as binary?

 --data-binary "data-id=2010-10-01_15-15-53" 

On this line, you say that you want to convey plain text, not binary:

 curl_setopt($this->_curl, CURLOPT_HTTPHEADER, array('Content-Type: text/plain'));

Anyway, I think your main problem is to use the PUT method. ( fooobar.com/questions/59752 / ... )

I recommend using the POST method this way:

 curl_setopt($this->_curl, CURLOPT_HTTPHEADER, array( 'Accept: */*', 'Connection: Keep-Alive', // this allows you transfer binary data through POST 'Content-type: multipart/form-data' )); curl_setopt($this->_curl, CURLOPT_POST, 1); curl_setopt($this->_curl, CURLOPT_POSTFIELDS, http_build_query(array('data-id' => $dataId)));
