为什么服务总线输出绑定不适用于 Azure Functions？ - 没有错误

Question

我尝试将 HTTPTriggered 消息发送到服务总线输出。 我正在关注https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-service-bus-output?tabs=csharp 的示例

当我从 Visual Studio Code 执行此代码时，我没有收到任何错误。 在这个我在本地调试。

但是服务总线门户说有 0 条传入消息。 可能有什么问题？ 代码有问题吗？

using System.IO;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;
using Microsoft.ServiceBus.Messaging;
using Microsoft.ServiceBus;


namespace Company.Function
{
    public static class HttpTriggerCSharp1
    {
    [FunctionName("ServiceBusOutput")]

    [return: ServiceBus("queue1", Connection ="Endpoint=sb://12345servicebus.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=12345+cmc8501HJ6Ips2OxIZKtO6gctT8d1ZpNN0GNw=")]
    public static string ServiceBusOutput([HttpTrigger] dynamic input, ILogger log)
    {

        //log.LogInformation($"C# function processed: {input.Text}");
        //return input.Text;
        return "MessageToServiceBus123"
    }
}

}

Http Functions:

Answer 1

正如文件所说，

您可以设置 Connection 属性以指定包含要使用的服务总线连接字符串的应用设置的名称

您应该在 local.settings.json 中将连接字符串值设置为键值对并提及该键

例如，

[FunctionName("ServiceBusOutput")]
[return: ServiceBus("myqueue", Connection = "ServiceBusConnection")]
public static string Run([HttpTrigger] dynamic input, ILogger log)

本地设置.json

{  
  "ServiceBusConnection": "whatever connection string"
}
