azure - 如何将 Microsoft Azure 存储模拟器与 Xamarin 结合使用？

Question

如何将 Microsoft Azure 存储模拟器与 Xamarin.Android 结合使用？ 我已下载 Microsoft Azure 存储模拟器和 Microsoft Azure 存储资源管理器。我尝试按照 Microsoft 网站上的教程进行操作，但仍然遇到身份验证问题。当我在免费试用订阅期间使用 real 时，一切正常。

我知道我必须使用 SAS key 。但是当我在存储资源管理器中创建表存储然后生成 SAS 时，它仍然是错误的。也许有人已经这样做了，并且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");

感谢您的宝贵时间。

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 地址是 127.0.0.1，因此请求实际上并未到达存储模拟器，而仅到达您的设备模拟器。这就是您收到此连接被拒绝错误的原因。请参阅此线程了解更多详细信息: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。当您确实使用实际存储帐户时，请使用下面的代码(显然适本地更改连接字符串)。它应该有效:

        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");
