.NET 6 Minimal API无法读取Azure Web App应用设置求助

我开发的.NET 6 Minimal API部署到Azure Web App后，无法读取Azure上配置的应用设置或连接字符串来覆盖本地配置。尝试过环境变量方式，仅能获取字符串值；常规配置读取方法在Azure环境下也不生效。本地调试时能正确读取appsettings.development.json的值，部署到Azure后却返回appsettings.json里的默认值。

本地配置文件 #

appsettings.json #

{    
    "ConnectionStrings": {         
        "Context": "",         
        "Redis": ""     
    },     
    "Logging": {         
        "LogLevel": {           
            "Default": "Information",           
            "Microsoft": "Warning",           
            "Microsoft.Hosting.Lifetime": "Information"         
        }   
    },     
    "Where": "Still AppSettings..." 
}

appsettings.development.json #

{   
    "ConnectionStrings": {     
        "Context": "...",     
        "Redis": "..."   
    },   
    "Logging": {      
        "LogLevel": {         
            "Default": "Information",         
            "Microsoft": "Warning",         
            "Microsoft.Hosting.Lifetime": "Information"      
        }   
    },   
    "Where": "Local", 
}

API端点代码 #

Home.cs中定义的端点逻辑：

namespace Endpoints{
    public static class HomeApi
    {
        public static void RegisterHomeAPI(this WebApplication app)
        {
            app.MapGet("/", Index);
            app.MapGet("/Home", Index);
            app.MapGet("/Home/Inxed", Index);
            app.MapPost("/", Index);
            app.MapPost("/Home", Index);
            app.MapPost("/Home/Inxed", Index);
        }
        // GET: Home
        public static string Index(IConfiguration configuration) => configuration["Where"] ?? "Failed";
    }
}

本地调试访问端点返回Local，部署到Azure后返回Still AppSettings...。

Program.cs中的配置代码 #

using DocumentFormat.OpenXml.InkML;
using Microsoft.OpenApi.Models;
using Twilio.Services;
using Twilio.Web.Endpoints;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddLogging();
builder.Services.AddApplicationInsightsTelemetry(options => { 
    options.ConnectionString = builder.Configuration.GetSection("ApplicationInsights").GetValue<string>("InstrumentationKey"); 
});
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen(c =>{
    c.SwaggerDoc("v1", new OpenApiInfo
    {
        Version = "v1",
        Title = "TEST API v1",
        Description = "TEST API documentation",
        Contact = new OpenApiContact() { Name = "CCS Dev", Email = "testing..." }
    });
});
var config = new ConfigurationBuilder()
    .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
    .AddEnvironmentVariables()
    .Build();
var appSettingValue = config["Where"];
var connection = config.GetConnectionString("Context");
builder.Services.AddScoped(c => new TestContext(builder.Configuration["Context"]));
builder.Services.AddStackExchangeRedisCache(options => { 
    options.Configuration = builder.Configuration.GetConnectionString("Redis"); 
});
var appSettings = builder.Configuration.GetSection("AppSettings");

builder.Services.AddScoped(c => new TestService(
    c.GetRequiredService<TestContext>(),
    c.GetRequiredService<ILogger<TestService>>()
));
builder.Services.AddAuthorization();

var app = builder.Build();

if (app.Environment.IsDevelopment()){}

app.UseRouting();

app.UseAuthorization();
app.RegisterHomeAPI();

app.UseSwagger();
app.UseSwaggerUI();

app.Run();
