Error inserting image into mailchimp

[mstdmstdd]

Hello,Making adding of files to mailchimp  as it is written here:

https://developer.mailchimp.com/documentation/mailchimp/reference/file-manager/files/

I do like :

$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_USERPWD, 'user:mykey' );
curl_setopt( $ch, CURLOPT_HTTPHEADER, [ 'Content-Type: application/json' ] );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_TIMEOUT, 10 );
curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, 'POST' );
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fileInfo ) );
$newFile = json_decode( curl_exec( $ch ) );

$fileInfo = [
'name' => $file_name,
'folder_id => 5673,
'file_data'=> $file_data
];

$file_name - is name of file like '0001.jpg', 5673 - id of folder and $file_data is content of file I read using lines like

$fd = fopen($file_name, "rb");
$contents = fread($fd, filesize($file_name));
fclose($fd);

 

$url is https://us7.api.mailchimp.com/3.0/file-manager/files

I got error

[message] => Schema describes object, NULL found instead

 

I am sure tha $url - is right and it has value - I get list of files using GET method for $url

https://us7.api.mailchimp.com/3.0/file-manager/files

 

What can the resason of this error? Is it wrong format of source file ?

 

  Thanks!

You did define $fileInfo before the cURL call, right? And in the same scope?

 

And

$fd = fopen($file_name, "rb");
$contents = fread($fd, filesize($file_name));
fclose($fd);

that is silly. I don't understand why people keep doing that.

[mstdmstdd]

Yes, $fileInfo  was defined before cURL call, in the same scope.

I also tried to use file_get_contents for - but the same error. But file_get_contents for - also returned string?

 

I thought the right way was to get bytes from image and for that I used 

fopen($file_name, "rb");

If there is a way to set example image as image text ? I mean just any small image just to check if the error was in wrong data format ?

[requinix]

The right way to get the contents of a file is with file_get_contents(). Dealing with a file handle and manually reading from the file is a chore. And swapping out the fopen/fread/fclose with file_get_contents will not affect anything with the API call.

 

The error says that the request body was null. That would mean json_encode() returned "null", which means $fileInfo was null. Probably.

 

What's the full code, uninterrupted, between defining $fileInfo and the cURL stuff?

I read file content

		$filename = '0001.jpg';
		$filename_content= file_get_contents($filename_path);
		$appMailchimp= new appMailchimp();
		$newMailChimpFile=$appMailchimp->addFile($filename, $filename_content);

and

public function addFile( $file_name, $file_data ) {
$is_debug = true;
$url = $this->m_base_url .'file-manager/files' ;

$fileInfo = [
'name' => $file_name,
'folder_id'=> 5673,
'file_data'=> $file_data
];
echo '<pre>-2 addFile $url::'.print_r($url,true).'</pre>';
if($is_debug) echo '<pre> -1 addFile $fileInfo::' . print_r( $fileInfo, true ) . '</pre>';


$ch = curl_init( trim($url) );
curl_setopt( $ch, CURLOPT_USERPWD, 'user:' . $this->m_mailchimp_api_key );
curl_setopt( $ch, CURLOPT_HTTPHEADER, [ 'Content-Type: application/json' ] );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_TIMEOUT, 10 );
curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, "POST" );
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );

curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fileInfo ) );
$newFile = json_decode( curl_exec( $ch ) );
var_dump($newFile);

and error :

Schema describes object, NULL found instead

According to the documentation, file_data is not simply the raw contents of the file. Take a look. Do you know what you need to do to fix that? It could be MailChimp is trying to un-

the file_data, comes up with nothing valid, and responds with that error message.
