如何通过PHP上传图片到Azure存储？

Question

我正在尝试通过使用 PHP.

构建的 API 将图像上传到我的 blob 存储

目前我有这个，base64 字符串正在通过 JSON Post.

发送

//The base 64 string
$displayPictureBase64 = $this->ValidateParameter('DisplayPicture', $this->param, STRING);
//Decode it to byte array.
$displayPicture[] = base64_decode($displayPictureBase64);
//Name of the blob
$blobName = "MyBlobName";

//New BlobStorage class.
$blob = new BlobStorage;
$blob->AddBlob('user-display-pictures', $blobName, $displayPicture);

这会调用函数 AddBlob...

public function AddBlob($containerName, $fileName, $fileToUpload)
{
//Upload blob
$this->blobClient->createBlockBlob($containerName, $fileName, $fileToUpload);
}

(PS。我有 blobClient 的凭据，只是没有在此处包含它以节省不必要的 space。)

我遇到的问题是函数 blobClient->createBlockBlob 采用这些参数...

 * @param string                          $container The name of the container.
 * @param string                          $blob      The name of the blob.
 * @param string|resource|StreamInterface $content   The content of the blob.

所以我遇到的问题是我发送的第三个参数是数组类型，但根据此它应该是字符串。这是我得到的 PHP 错误...

PHP Fatal error: Uncaught InvalidArgumentException: Invalid resource type: array in D:\home\vendor\guzzlehttp\psr7\src\functions.php:116

如何将图像作为字符串上传到 blob 存储？这里的docs只说明了如何上传文本文件，而不是图片文件。谢谢！

我通过执行以下操作修复了它...

//The base 64 string
$displayPictureBase64 = $this->ValidateParameter('DisplayPicture', $this->param, STRING);

//Convert the file to stream
$fileToUpload = fopen('data:image/jpeg;base64,' . $displayPictureBase64,'r');
//Name of the blob
$blobName = "MyBlobName";

//New BlobStorage class.
$blob = new BlobStorage;
$blob->AddBlob('user-display-pictures', $blobName, $fileToUpload);
