问题描述

我一直在努力将我们的一个 Azure Functions 实现升级到 .net 5。我已经与可能的恶魔作斗争,但就像我已经整理了所有配置和依赖注入更改一样,它向我抛出了一个曲线球。在host.RunAsyncin之后Main,我得到以下异常,我对罪魁祸首有点不知所措。有没有人遇到并修复了这个?

System.UriFormatException

  This exception was originally thrown at this call stack:
    [External Code]

我的 Program.cs 主要看起来像:

using Microsoft.Extensions.Hosting;
using System.Threading.Tasks;

namespace FunctionApp1
{
    /// <summary>
    /// Entry
    /// </summary>
    public class Program
    {
        static async Task Main(string[] args)
        {
            var host = new HostBuilder()
                .ConfigureFunctionsWorkerDefaults()
                .Build();

            await host.RunAsync();
        }
    }
}

我的功能

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

namespace FunctionApp1
{
    /// <summary>
    /// 
    /// </summary>
    public static class Function1
    {
        /// <summary>
        /// 
        /// </summary>
        /// <param name="req"></param>
        /// <param name="ctx"></param>
        /// <returns></returns>
        [FunctionName("Function1")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequestData req, FunctionContext ctx)
        {
            ctx.GetLogger("out").LogInformation("C# HTTP trigger function processed a request.");

            string name = req.ReadAsString();

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

            string responseMessage = string.IsNullOrEmpty(name)
                ? "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
                : $"Hello, {name}. This HTTP triggered function executed successfully.";

            return new OkObjectResult(responseMessage);
        }
    }
}

当我使用时,func host start我还收到错误“找不到工作职能。尝试公开你的工作类别和方法。”

解决方案


目前,.net 5 azure functionVisual Studio 等工具还不能很好地支持。func host start您可以在Azure Functions Core Tools中使用此命令来运行您的函数。

github中也有类似的issue,详细可以参考issue
