我在local.settings.json中有以下值
x1c 0d1x的数据
我在我的启动类中访问相同的，我为我的Azure函数添加了如下内容

public override void Configure(IFunctionsHostBuilder builder)
    {
        IConfiguration config;
        var environment = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");
        config = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddEnvironmentVariables()
            .AddJsonFile($"local.settings.json", optional: true, reloadOnChange: true)
            .Build();
        builder.Services.Replace(ServiceDescriptor.Singleton(typeof(IConfiguration), config));
        builder.Services.AddLogging();
        var executionContextOptions = builder.Services.BuildServiceProvider()
        .GetService<IOptions<ExecutionContextOptions>>().Value;
        var currentDirectory = executionContextOptions.AppDirectory;
        builder.Services.AddSingleton<IConfiguration>(config);
        #region Serilog
        Log.Logger = new LoggerConfiguration()
        .MinimumLevel.Information()
        .MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
        .MinimumLevel.Override("Worker", LogEventLevel.Warning)
        .MinimumLevel.Override("Host", LogEventLevel.Warning)
        .MinimumLevel.Override("System", LogEventLevel.Error)
        .MinimumLevel.Override("Function", LogEventLevel.Error)
        .MinimumLevel.Override("DurableTask", LogEventLevel.Error)
        .MinimumLevel.Override("Azure.Storage.Blobs", LogEventLevel.Error)
        .MinimumLevel.Override("Azure.Core", LogEventLevel.Error)
        .MinimumLevel.Override("Azure.Messaging.ServiceBus", LogEventLevel.Error)
        .Enrich.FromLogContext()
        .WriteTo.Console()
        .WriteTo.AzureAnalytics(config["AZURE_WORKSPACE_ID"],///<-***issue here///
         config["AZURE_AUTHENTICATION_ID"])
        .Enrich.WithEnvironmentName()
        .CreateLogger();
        builder.Services.AddLogging(lb => lb.AddSerilog(Log.Logger, true));
        #endregion
        
    }

它在本地工作正常，但在生产环境中，即使我在应用程序设置中有AZURE_WORKSPACE_ID键，

的
我得到以下错误
Microsoft.Azure.WebJobs.Script.ExternalStartupException：在外部启动类中配置服务时出错。-> System.ArgumentNullException：值不能为空。（参数“workspaceId”）在Serilog. LoggerOperationExtensions.AzureAnalytics（LoggerSinkConfiguration loggerConfiguration，String workspaceId，String authenticationId，String logName，LogEventLevel restrictedToMinimumLevel，Boolean storeTimestampInUtc，IstampProvider formatProvider，Int32 logBufferSize，Int32 batchSize，AzureOfferingType azureOfferingType、LoggingLevelSwitch levelSwitch、Boolean对象、String代理）
AZURE_WORKSPACE_ID值未被拾取

这段代码在本地和Azure上都适用，如下所示：
我在.NET 7 isolated中创建了一个HTTP触发器函数，它从本地的local.settings.json和Azure的app settings中获取自定义环境变量。

Program.cs：

using Microsoft.Extensions.Configuration;  
using Microsoft.Extensions.Hosting;
var host = new HostBuilder()  
.ConfigureFunctionsWorkerDefaults()  
.Build();
var config = new ConfigurationBuilder()  
.SetBasePath(Environment.CurrentDirectory)  
.AddEnvironmentVariables()  
.AddJsonFile($"local.settings.json",optional: true, reloadOnChange:true)  
.Build();
host.Run();

字符串

Function1.cs：

using System.Net;  
using Microsoft.Azure.Functions.Worker;  
using Microsoft.Azure.Functions.Worker.Http;  
using Microsoft.Extensions.Configuration;  
using Microsoft.Extensions.Logging;
namespace FunctionApp5  
{  
public class Function1  
{  
private readonly ILogger _logger;  
private readonly IConfiguration _config;
public Function1(IConfiguration configuration, ILoggerFactory loggerFactory)  
{  
_logger = loggerFactory.CreateLogger<Function1>();  
_config = configuration;  
}
[Function("Function1")]  
public HttpResponseData Run([HttpTrigger(AuthorizationLevel.Anonymous, "get", "post")] HttpRequestData req)  
{  
_logger.LogInformation("C# HTTP trigger function processed a request.");
string value = _config["Azure_custom_variable"];
var response = req.CreateResponse(HttpStatusCode.OK);  
response.Headers.Add("Content-Type", "text/plain; charset=utf-8");
response.WriteString($"Welcome to Azure Functions! \n\n {value}");
return response;  
}  
}  
}
