Etsy API 图片上传错误

我有一个 oauth 连接 - 它可以很好地处理所有其他请求，但有一个： 上传列表图像。 这是代码：

$connection = $this->getEtsyConnection();

$imageApiUrl = 'https://openapi.etsy.com/v2/listings/'.$listingId.'/images';
$mimeType = mime_content_type($source_file);
$filesize = filesize($source_file);

$params = ['@image' => ''.$source_file.';type='.$mimeType, 'rank'=>1, 'overwrite'=>true, 'listing_id'=>intval($listingId) ];
$header = [
            'Content-Type' => 'multipart/form-data',
          ];
try {
    if ( file_exists( $source_file ) ) {                                      
        $connection->fetch($imageApiUrl, $params, OAUTH_HTTP_METHOD_POST, $header);
        $json = $connection->getLastResponse();
        print_r( json_decode($json, true) );
    }                            
} catch (\OAuthException $e) {
    $json = $connection->getLastResponse();
    print_r( $json );
    print_r( $params );
    print_r( $header );
    print_r( $connection->debugInfo );
    print_r( $e->getMessage() );
}

但是，得到的回应是：

我缺少什么？文件未上传，出现上述错误。

经过多次尝试，我找到了使用curl的解决方法。我想我应该分享它，这样任何有同样问题的人都可以使用它。

$oauth = new OAuth($api_key, $api_secret, OAUTH_SIG_METHOD_HMACSHA1, OAUTH_AUTH_TYPE_URI);
$oauth->setToken($access_token, $access_token_secret);

$url = "https://openapi.etsy.com/v2/listings/864452611/images";
$method = "POST";
$image_path = "/path/to/image.jpg";

$file = new \CURLFile($image_path, mime_content_type($image_path), basename($image_path));

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array('image' => $file));
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'method' => $method,
    'header' => 'Content-Type: multipart/form-data; boundary=' . microtime(true),
    'header' => 'Authorization: ' . $oauth->getRequestHeader($method, $url)
));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec($ch);
print_r(json_decode($server_output, true));

curl_close ($ch);
