如何在Xamarin中使用Microsoft Azure存儲模擬器？

Question

如何在Xamarin.Android上使用Microsoft Azure存儲模擬器？ 我已經下載了Microsoft Azure存儲模擬器和Microsoft Azure存儲資源管理器。我試圖在Microsoft網站上關注教程，但仍然遇到了身份驗證問題。當我在免費試用期間使用real時，一切正常。

我知道我必須使用SAS密鑰。但是，當我在存儲資源管理器中創建表存儲並在那裏生成SAS時，它仍然是錯誤的。也許有人已經這樣做了，可以粘貼他的代碼或步驟來重現與存儲模擬器的連接。

const string connectionString = "SharedAccessSignature=sv=2015-04-05&sr=c&sig=91HcGtCMxWM6%2B13mRDH1kej5Wq1a8gRk4WCFd6CeLuk%3D&se=2016-08-01T12%3A16%3A55Z&sp=rwdl;TableEndpoint=http://127.0.0.1:10002/devstoreaccount1"; 

CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionString); 
CloudTableClient tableClient = storageAccount.CreateCloudTableClient(); 
CloudTable table = tableClient.GetTableReference("Test"); 
bool exists = await table.ExistsAsync(); 
if (exists) 
    System.Console.WriteLine("Exists"); 
else 
    System.Console.WriteLine("Doesnt exist");

謝謝您的時間。

我相信你得到這個錯誤是因爲你在模擬器中運行這段代碼。由於模擬器的IP地址爲127.0.0.1，請求實際上並不是實際觸及存儲模擬器，而只是您的設備模擬器。這就是爲什麼你得到這個連接拒絕錯誤。請參閱此主題了解更多詳情：https://forums.xamarin.com/discussion/1199/how-to-make-our-remote-host-127-0-0-1-reachable-from-android-device-monoandroid-using-vs2010。

我會推薦的是，您使用實際的雲存儲帳戶而不是存儲模擬器來測試您的代碼。當您使用實際的存儲帳戶時，請使用下面的代碼（顯然請適當更改連接字符串）。它應該工作：

 var connectionString = "http://127.0.0.1/devstoreaccount1/Testowa?st=2015-07-31T11%3A50%3A00Z&se=2017-0‌​8-01T11%3A50%3A00Z&sp=raud&sv=2015-04-05&tn=testowa&sig=UEbinBTgpEGwy1ts0hwmSfELM‌​1lYCBItLHgWpWSgvE4%3D"; 
     CloudTable table = new CloudTable(new Uri(connectionString)); 
     bool exists = await table.ExistsAsync(); 
     if (exists) 
      System.Console.WriteLine("Exists"); 
     else 
      System.Console.WriteLine("Doesnt exist");
