使用 Azure 服务总线生成 RSS 源

Question

我希望让客户使用 RSS Reader.

订阅 Azure 服务总线上的主题

我似乎找不到有关如何开始从服务总线动态生成提要的文档

谁能给我指点一下？

Answer 1

Service Bus 在命名空间的根部自行生成一个 ATOM 提要，称为“服务注册表”。它位于 https://yournamespace.servicebus.windows.net，当您使用浏览器。

要探索命名空间提要（它是 ATOM 提要的嵌套结构），您需要在 "Authorization" 或 "ServiceBusAuthorization" 中为命名空间的根提供一个 SAS token with "Manage" access header 的 HTTP GET 请求。标准 "RootManageSharedAccessKey" 规则具有该权利。

    class Program
    {
        static void Main(string[] args)
        {
            // for connection string: 
            // Endpoint=sb://[[yournamespace]].servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=[[key]]

             var tp = TokenProvider.CreateSharedAccessSignatureTokenProvider("RootManageSharedAccessKey", "[[key]]");
            var token = tp.GetWebTokenAsync("http://[[yournamespace]].servicebus.windows.net/", string.Empty, true, TimeSpan.FromHours(1))
                .GetAwaiter()
                .GetResult();
            Console.WriteLine(token);
        }
    }

在控制台应用程序中使用上面的代码片段（使用 SB NuGet 包），您将获得所需的令牌字符串以放入 HTTP header。

当我在 HTTP "Authorization:" header 中将该令牌与我在 Fiddler 的作曲家中的一个命名空间一起用于根目录上的 HTTPS GET 时，我得到

并且在遵循测试队列的 link 时（但使用 HTTPS 来保护令牌），我得到
