Question

如何在Xamarin.Android中使用Microsoft Azure存储模拟器？我已下载Microsoft Azure存储模拟器和Microsoft Azure存储资源管理器。我试图在微软网站上关注教程，但我仍然遇到身份验证问题。当我在免费试用期间使用真实订阅时，一切正常。

我知道我必须使用SAS密钥。但是当我在存储资源管理器中创建表存储然后在那里生成SAS时，它仍然是错误的。也许有人已经这样做了，可以粘贴他的代码或步骤来重现与存储模拟器的连接。

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");

感谢您的时间。

我相信您收到此错误是因为您在模拟器中运行此代码。由于模拟器的IP地址为127.0.0.1，因此请求实际上并未访问存储模拟器，而只是您的设备模拟器。这就是为什么你得到这个连接拒绝错误。有关详细信息，请参阅此主题：https://forums.xamarin.com/discussion/1199/how-to-make-our-remote-host-127-0-0-1-reachable-from-android-device-monoandroid-using-vs2010。

我建议您使用实际的云存储帐户而不是存储模拟器来测试您的代码。当您使用实际存储帐户时，请使用下面的代码（显然适当地更改连接字符串）。它应该工作：

        var connectionString = "http://127.0.0.1/devstoreaccount1/Testowa?st=2015-07-31T11%3A50%3A00Z&se=2017-0‌8-01T11%3A50%3A00Z&sp=raud&sv=2015-04-05&tn=testowa&sig=UEbinBTgpEGwy1ts0hwmSfELM‌1lYCBItLHgWpWSgvE4%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");
