Xamarin Azure Blobストレージが返品/承認されていません

Question

私はXamarin Storageスニペットをすべて試しましたが、Azureは何も返さず、何も保管しません。それはしばしば例外をスローしませんが、それは見えるコードの多くを無視します。

私がダウンしてこれらの午前：

public async Task<string> TestStorage() 
{ 
    CloudBlobContainer container = new CloudBlobContainer(new Uri(Settings.StorageContainerUrl), new StorageCredentials(Settings.StorageAccountName, Settings.StorageAccountKey)); 
    //CloudBlockBlob blob = container.GetBlockBlobReference("mytest2"); 
    //await blob.UploadTextAsync("This is newly uploaded data"); 
    CloudBlockBlob blob = container.GetBlockBlobReference("mytest"); 
    string data = await blob.DownloadTextAsync(); 
    return data; 
} 

私はそれを間違ったStorageContainerUrlまたはStorageAccountNameを与える場合は、アズールは、エラーがスローされます。これまでのところ、その情報は接続して検証する必要があります。また、存在しないBLOB名を使用するとAzure Storageがスローすることを確認しましたStorageException：指定されたBLOBが存在しません。

しかし、私がそれに悪いStorageAccountKeyを与えると、例外はスローされません。

さらに、DownloadTextAsyncコマンドは、既存のBLOBに対しては何も返しません。実際には返されず、文字列データは設定されません。最終的には例外がスローされます。私はUploadTextAsyncのコメントを解除した場合

が、それはまた、何もしないし、何のブロブは、Azureの上で作成されません。

私はおそらく単純なエラーをコミットしていますが、CloudStorageAccount.Parse、CreateCloudBlobClientなどのすべての組み合わせを試しました。私はそれが悪いURLやアカウントを与える場合私はAzureから取得している例外のために私は正しい軌道にいると思う。

Answer 1

例外はまだXamarinでは実装されていないハッシュ関数によるものと思われます。詳細は、問題を参照してください。https://github.com/Azure/azure-storage-net/issues/387

解決策は、修正するまでAzure Storage 7.2.1に戻すことです。
