无法使用 CreateTopicAsync 在 ServiceBus 中创建新主题

Question

我正在尝试使用库 Microsoft.Azure.ServiceBus.Management 的方法 CreateTopicAsync 创建一个新主题（然后是订阅）。连接字符串正确，如果我通过 Azure 门户创建主题，我可以发送和接收消息。我究竟做错了什么？感谢任何帮助。

var managementClient = new ManagementClient(ServiceBusConnectionString);
bool topicExists = await managementClient.TopicExistsAsync(TopicName).ConfigureAwait(false);
if (!topicExists) {
    TopicDescription td = new TopicDescription(TopicName);
    td.MaxSizeInMB = 1024;
    td.DefaultMessageTimeToLive = new TimeSpan(2, 0, 0, 0);
    await managementClient.CreateTopicAsync(td).ConfigureAwait(false);
}

尽管服务总线 ConnectionString 可能是正确的，但要使您的应用程序能够创建主题，它需要具有 Manage 权利（声明）。

取自Service Bus access control with Shared Access Signatures:

For each authorization policy rule, you decide on three pieces of information: name, scope, and rights. The name is just that; a unique name within that scope. The scope is easy enough: it's the URI of the resource in question. For a Service Bus namespace, the scope is the fully qualified domain name (FQDN), such as https://.servicebus.windows.net/.

The rights conferred by the policy rule can be a combination of:

'Send' - Confers the right to send messages to the entity

'Listen' - Confers the right to listen (relay) or receive (queue, subscriptions) and all related message handling

'Manage' - Confers the right to manage the topology of the namespace, including creating and deleting entities

The 'Manage' right includes the 'Send' and 'Receive' rights.
