Question

我已经从Visual Studio创建并发布了一个Http触发的Azure函数，该函数用于连接到IoT中心并获取模块的twin属性。

我已经使用模块连接字符串配置了 local.settings.json 文件，并且还在门户网站的应用程序设置中添加了该文件。但是，当我在门户中运行该功能时，它会给我内部服务器错误500。

我正在运行的Azure功能版本是v1。

我正在使用的

json文件：

local.settings.json

new Object(){}.getClass().getEnclosingMethod().getParameterTypes()

host.json

{
      "IsEncrypted": false,
      "Values": {
        "AzureWebJobsStorage": "xxxxxxxx",
        "AzureWebJobsDashboard": "xxxxxx",
        "FUNCTIONS_WORKER_RUNTIME": "dotnet",
        "ModuleConnectionString": "xxxxxxxxx"
      }
    }

function.json

{
  "http": {

"routePrefix": "api",

"maxOutstandingRequests": 20,

"maxConcurrentRequests": 10,

"dynamicThrottlesEnabled": false

    },

 "version": "2.0"

}

以下是代码：

function1.cs

{
  "generatedBy": "Microsoft.NET.Sdk.Functions-1.0.19",
  "configurationSource": "attributes",
  "bindings": [
    {
      "type": "httpTrigger",
      "methods": [
        "get",
        "post"
      ],
      "authLevel": "function",
      "name": "req"
    }
  ],
  "disabled": false,
  "scriptFile": xxxx.dll",
  "entryPoint": "xxxxxxxx.Run"
}

twin.cs

    public static class Function1
    {
        [FunctionName("Function1")]
        public static async Task Run([HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)]HttpRequest req, ILogger log)
        {
            log.LogInformation("C# HTTP trigger function processed a request.");


            var moduleConnectionString = Environment.GetEnvironmentVariable("ModuleConnectionString", EnvironmentVariableTarget.Process);


            ModuleClient _moduleClient = ModuleClient.CreateFromConnectionString(moduleConnectionString, TransportType.Amqp);

            var sample = new TwinSample(_moduleClient);
            await sample.RunSampleAsync();
       }
    }

我尝试将运行时版本从1更改为2，反之亦然。仍然无法正常工作。同样在“应用程序设置”下，我已设置

WEBSITE_NODE_DEFAULT_VERSION

从6.5.0到8.11.1。

有人可以帮我解决这个问题吗？

HTTP Function应该实际上返回HTTP结果，请尝试将Function更改为

public static async Task<HttpResponseMessage> Run(
    [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequestMessage req, 
    ILogger log)
{
    // your code goes here
    return req.CreateResponse(HttpStatusCode.OK, "Done");
}

在门户中运行Azure功能时出现内部服务器错误
