Problem with uploading files

[melvinchia]

I'm able to list files and read file contents from Azure File Storage, so I'm pretty sure my connection string is fine.
When I try to write/update a file, I get the following error:

403: Fail: Code: 403 Value: Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature. details (if any): <?xml version="1.0" encoding="utf-8"?><Error><Code>AuthenticationFailed</Code><Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature. RequestId:33698f74-a01a-005c-7ab3-6f6a14000000 Time:2020-08-11T07:48:02.1835762Z</Message><AuthenticationErrorDetail>The MAC signature found in the HTTP request 'l+Lz9lBDaKq9VZ3k9zoBozQ5j9prREu0VkO9i/LxzxU=' is not the same as any computed signature. Server used following string to sign: 'GET application/x-www-form-urlencoded Tue, 11 Aug 2020 07:48:02 GMT x-ms-request-id:5f324d322c9eb x-ms-version:2016-05-31 /sjlmsib/s3ib/smarthub_sync/new/ restype:directory'.</AuthenticationErrorDetail></Error>.

I'm able to write to the file using the same connection string, but Microsoft API's createFileFromContent function, so I'm sure that my access rights allow me to create and write the destination file.

For reference, this works (it creates the file in the Azure File Share)
$microsoftFileClient->createFileFromContent('share', 'test.csv', $testdata);

And this doesn't work (it produces the error above)
$azureFileAdapterClient->write('test.csv', $testdata);

Any way to fix?

Sorry, only just spotted this.

I did get a similar error and thought I had fixed it. The error message is a bit of a misnomer, and just means the request is malformed, and it happened after an MS library update. Could you include some PHP and related package versions for me to check please.

Is it a stream you are uploading, orca file from disk?

[melvinchia]

I tried a file from disk, and just a data array/stream, neither worked.

I'm on PHP 5.6.40, and consilience/flysystem-azure-file-storage is at 0.1.4. league/flysystem is at 1.0.70.

I'm using a later version of PHP (7.3 and 7.4) and not seeing a problem writing files.

I'm using academe/laravel-azure-file-storage-driver to deliver the config settings from a Laravel filesystem to this package. The setting looks like this:

        'my-uploads-filesystem' => [
            'driver' => 'azure-file-storage', // This driver.

            'storageAccount' => env('AZURE_FILE_STORAGE_ACCOUNT'),
            'storageAccessKey' => env('AZURE_FILE_STORAGE_ACCESS_KEY'),

            // The file share.
            'fileShareName' => env('AZURE_FILE_STORAGE_NAME', 'name-of-azure-file-share'),

            // Optional settings
            'disableRecursiveDelete' => true,
            'driverOptions' => [],

            'root' => env('MY_ROOT', 'uploads'),
        ],

You may not be using Laravel, but those are the assential settings that are mapped to the driver. I'm not sure what could be happening to cause the MAC signature error, other then the authentication details. The access key I am using is a string of mixed case alpha-numeric characters with "==" at the end.

I get exactly the same error with incorrect authenticarion details just listing files in a directory, if that helps.

I'm unable to use PHP7, due to other dependencies on the project and server..

But since I'm able to list and read the file contents of a test file I put up, it shows that something is working, and something isn't correct? 😅
