如何在不使用 Laravel 中的任何库的情况下将文件上传到 Azure Blob 存储？

Question

我对一些图书馆的停办感到困惑和忧伤。

我想将文本文件上传到Azure Blob Storage。但是这个功能不起作用。

    private static function output($path, $text): bool
    {
        $accountName = config('filesystems.disks.azure.account_name');
        $containerName = config('filesystems.disks.azure.container_name');
        $sasToken = config('filesystems.disks.azure.sas_token');
        $uri = "https://{$accountName}.blob.core.windows.net/{$containerName}/{$path}";
        $version = '2024-05-04';

        $checkUri = "{$uri}?{$sasToken}";
        $checkResponse = Http::withHeaders([
            'x-ms-version' => $version,
            'x-ms-date' => gmdate('D, d M Y H:i:s T'),
        ])->head($checkUri);
        
        if ($checkResponse->status() == 404) {
            $createUri = "{$uri}?{$sasToken}";
            $createResponse = Http::withHeaders([
                'x-ms-blob-type' => 'AppendBlob',
                'x-ms-date' => gmdate('D, d M Y H:i:s T'),
                'x-ms-version' => $version,
            ])->put($createUri);
            
            if (!$createResponse->successful()) {
                throw new \Exception('Failed to create new blob: ' . $createResponse->body());
            }
        }

        $appendUri = "{$uri}?comp=appendblock&{$sasToken}";
        $response = Http::withHeaders([
            'Content-Type' => 'application/octet-stream',
            'x-ms-date' => gmdate('D, d M Y H:i:s T'),
            'x-ms-version' => $version,
        ])->put($appendUri, $text);
        
        if ($response->successful()) {
            return true;
        } else {
            throw new \Exception('Failed to append content: ' . $response->body());
        }
    }

错误信息 我不知道这个错误的原因。

Failed to create new blob: <?xml version="1.0" encoding="utf-8"?><Error><Code>InvalidHeaderValue</Code><Message>The value for one of the HTTP headers is not inn the correct format.
Time:2024-05-08T02:04:08.7165841Z</Message><HeaderName>Content-Length</HeaderName><HeaderValue>2</HeaderValue></Error>

Answer 1

encoding="utf-8"?><Error><Code>InvalidHeaderValue</Code><Message>The
value for one of the HTTP headers is not in the correct format.
Time:2024-05-08T02:04:08.7165841Z</Message><HeaderName>Content-Length</HeaderName><HeaderValue>2</HeaderValue></Error>

出现上述错误是因为您没有在 API 请求中使用

'Content-Length'

标头。

注意： 根据此 MS-Document 仅当使用

Append Block

设置为

x-ms-blob-type

创建 Blob 时才允许

AppendBlob

操作。

在我的环境中，我有一个名为

testblob.txt

的附加 blob，如下所示：

传送门：

现在，使用下面的代码，它将 blob 添加到我的文本文件中。

代码：

 private static function output($path, $text): bool
    {
        $accountName = config('filesystems.disks.azure.account_name');
        $containerName = config('filesystems.disks.azure.container_name');
        $sasToken = config('filesystems.disks.azure.sas_token');
        $uri = "https://{$accountName}.blob.core.windows.net/{$containerName}/{$path}";
        $version = '2024-05-04';

        $checkUri = "{$uri}?{$sasToken}";
        $checkResponse = Http::withHeaders([
            'x-ms-version' => $version,
            'x-ms-date' => gmdate('D, d M Y H:i:s T'),
        ])->head($checkUri);
        
        if ($checkResponse->status() == 404) {
            $createUri = "{$uri}?{$sasToken}";
            $createResponse = Http::withHeaders([
                'x-ms-blob-type' => 'AppendBlob',
                'x-ms-date' => gmdate('D, d M Y H:i:s T'),
                'x-ms-version' => $version,
            ])->put($createUri);
            
            if (!$createResponse->successful()) {
                throw new \Exception('Failed to create new blob: ' . $createResponse->body());
            }
        }

        $appendUri = "{$uri}?comp=appendblock&{$sasToken}";
        $length = strlen($text);
        $response = Http::withHeaders([
            'Content-Type' => 'application/octet-stream',
            'Content-Length' => $length,
            'x-ms-date' => gmdate('D, d M Y H:i:s T'),
            'x-ms-version' => $version,
        ])->put($appendUri, $text);
        
        if ($response->successful()) {
            return true;
        } else {
            throw new \Exception('Failed to append content: ' . $response->body());
        }
    }

我提供了

$text='The cat sat on the mat. The quick brown fox jumps over the lazy dog.'

。附加 blob。

输出：

以上执行并追加成功。

通过从 blob 存储下载文件进行验证。

文件：
