【英文标题】：Create Attachment in Azure Project is not working

【问题描述】：

。在开始时创建附件。但现在使用相同的代码和相同的图像在每次调用时创建黑色图像。 https://docs.microsoft.com/en-us/rest/api/azure/devops/wit/attachments/create?view=azure-devops-rest-6.0#examples

代码示例

$data = fopen("test.png", 'rb');
$size = filesize($file);
$contents = fread($data, $size);
fclose($data);
$encodedData = base64_encode($contents);
        
$url = "https://dev.azure.com/OrganizationName/ProjectId/_apis/wit/attachments?fileName=test.png&uploadType=simple&api-version=6.0";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$header = array("Authorization:Basic ".base64_encode($params['username'].":".$params['token']),"Content-Type:application/octet-stream");
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
if ($params['request']) 
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($encodedData));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);

回应是

stdClass Object
    (
    [id] => f1f55c9e-8f48-4408-90f0-69ebb3c4d0ff
    [url] => https://dev.azure.com/muhammadhaneef0757/749218ab-92a7-4ed1-86d8-738d8c3888e8/_apis/wit/attachments/f1f55c9e-8f48-4408-90f0-69ebb3c4d0ff?fileName=test.png
    )
when i check url in browser there is showing black image

已解决的代码示例

$data = fopen("test.png", 'rb');
$size = filesize($file);
$contents = fread($data, $size);
fclose($data);
        
$url = "https://dev.azure.com/OrganizationName/ProjectId/_apis/wit/attachments?fileName=test.png&uploadType=simple&api-version=6.0";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$header = array("Authorization:Basic ".base64_encode($params['username'].":".$params['token']),"Content-Type:application/octet-stream");
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $contents);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

$response = json_decode($response);

$postRequest = [];
$postRequest[] = ["op"=>"add",
"path"=> ("/relations/-"),
'from' => null,
"value"=> ["rel"=>"AttachedFile",
            "url"=>$response->url
            
            ]
];
$url = "https://dev.azure.com/OrganizationName/ProjectId/_apis/wit/workitems/workitemId?api-version=6.0";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$header = array("Authorization:Basic ".base64_encode($params['username'].":".$params['token']),"Content-Type:application/json-patch+json");
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PATCH");
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($postRequest));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
