无法从Azure函数向服务总线队列写入消息

Question

我试图按照文档从Azure函数(https://docs.microsoft.com/en-us/Azure/azure-functions/functions-bindings-service-bus-output？tabs=csharp)向Azure服务总线队列写入消息。

我从HTTP触发器的“file->new project”开始，并添加了绑定：

[FunctionName("Message")]
[return: ServiceBus("namequeue")]
public static async Task<string> Run(
    [HttpTrigger(AuthorizationLevel.Anonymous, "post", Route = null)] HttpRequest req,
    ILogger log)
{
    log.LogInformation("C# HTTP trigger function processed a request.");

    string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
    dynamic data = JsonConvert.DeserializeObject(requestBody);
    string name = data?.name ?? "DefaultName";

    return name;
}

我的host.json和local.settings.json文件包含：

"extensions": {
    "serviceBus": {
        "prefetchCount": 100,
        "messageHandlerOptions": {
            "autoComplete": true,
            "maxConcurrentCalls": 32,
            "maxAutoRenewDuration": "00:05:00"
        },
        "sessionHandlerOptions": {
            "autoComplete": false,
            "messageWaitTimeout": "00:00:30",
            "maxAutoRenewDuration": "00:55:00",
            "maxConcurrentSessions": 16
        },
        "batchOptions": {
            "maxMessageCount": 1000,
            "operationTimeout": "00:01:00",
            "autoComplete": "true"
        }
    }
},
"Values": {
    "AzureWebJobsServiceBus": "Endpoint=<redacted>"
}

当在本地运行时，我会得到一个超时异常（可能是公司防火墙）。

当部署到Azure时，我可以发送到函数，得到204回复，但是没有消息被添加到队列中。

{
  "generatedBy": "Microsoft.NET.Sdk.Functions-3.0.13",
  "configurationSource": "attributes",
  "bindings": [
    {
      "type": "httpTrigger",
      "methods": [
        "post"
      ],
      "authLevel": "anonymous",
      "name": "req"
    }
  ],
  "disabled": false,
  "scriptFile": "../bin/AppMapServiceBusCreate.dll",
  "entryPoint": "AppMapServiceBus.CreateMessageFunction.Run"
}

<PackageReference Include="Microsoft.Azure.WebJobs.Extensions.ServiceBus" Version="4.3.0" />

如果这是准确的，我如何/什么添加到function.json？

对于使用输出触发器写入服务总线的Azure函数，您需要将连接字符串作为应用程序设置添加到函数的配置中。默认情况下，预期的设置名称为AzureWebJobsServiceBus:
