ExecutionContext 在 Microsoft.Azure.Functions.Worker 中的实现？

Question

我正在将用net461编写的Azure Function V1升级到net48中的Azure Functions V4，同时在

ExecutionContext

中存在一些

Microsoft.Azure.WebJobs

，这里正在使用

string appDirectoryPath = context.FunctionDirectory;

，请帮助我找到一个可以与

一起使用的实现Microsoft.Azure.Functions.Worker

隔离函数确实有

ExecutionContext

但它没有

FunctionDirectory

属性，请参阅此 MS Doc。

如果您想访问功能位置，可以使用

Path.GetFullPath(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location))

。通过使用这个，我能够获得预期的功能位置。

using Microsoft.Azure.Functions.Worker;
using Microsoft.Azure.Functions.Worker.Http;
using Microsoft.Extensions.Logging;
using System.IO;
using System;
using System.Net;
using System.Reflection;
using System.Threading;

namespace _78372475
{
    public class Function1
    {
        private readonly ILogger _logger;

        public Function1(ILoggerFactory loggerFactory)
        {
            _logger = loggerFactory.CreateLogger<Function1>();
        }

        [Function("Function1")]
        public HttpResponseData Run([HttpTrigger(AuthorizationLevel.Anonymous, "get", "post")] HttpRequestData req)
        {
            _logger.LogInformation("C# HTTP trigger function processed a request.");

            var path = Path.GetFullPath(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location));
            _logger.LogInformation("Function Path: {Path}", path);

            var response = req.CreateResponse(HttpStatusCode.OK);
            response.Headers.Add("Content-Type", "text/plain; charset=utf-8");

            response.WriteString("Welcome to Azure Functions!");

            return response;
        }
    }
}

.csproj-

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net48</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
    <OutputType>Exe</OutputType>
