这个错误通常是由于混合连接字符串中的Authorization规范无效而引起的。请检查连接字符串是否正确设置并确保Authorization规范正确。以下是示例代码：

var connectionString = "Endpoint=sb://.servicebus.windows.net/;SharedAccessKeyName=;SharedAccessKey="; var hybridConnectionName = "";

var hybridConnection = new HybridConnectionClient(new Uri($"sb://{connectionString}/;EntityPath={hybridConnectionName}"));

// 改变认证规范 var signature = SasTokenProvider.GetSharedAccessSignature("", ""); var serviceEndpointUri = new Uri($"sb://{connectionString}/;SharedAccessKeyName=;SharedAccessSignature={signature}"); var hybridConnection = new HybridConnectionClient(serviceEndpointUri);

// 连接到混合连接 var relayConnection = await hybridConnection.CreateRelayConnectionAsync(); Console.WriteLine($"Connected to relay: {relayConnection.Id}"); Console.ReadLine();
