我正在尝试在测试API上加载我的appsettings.test.json文件，但阅读环境变量时遇到问题。在本地运行正常，但当我将其推送到Azure应用服务时，总是指向我的dev appsettings.json文件。
我将在下面附上我的设置和我用来验证这个问题的API调用结果。每个其他自定义值都可以在ASPNETCORE_ENVIRONMENT之外使用。

Azure应用服务应用程序设置

用于测试的应用程序服务终结点

[HttpGet("env")]
public IActionResult GetEnvVariable()
{
    var test = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");
    var test1 = Environment.GetEnvironmentVariable("DOTNET_ENVIRONMENT");
    return Ok($"ASPNETCORE: {test}\nDOTNET: {test1}");
}

应用程序服务终结点响应

程序. cs

public class Program
{
    public static void Main(string[] args)
    {
        CreateWebHostBuilder(args).Build().Run();
    }

    public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args).UseStartup<Startup>();

其他信息此应用程序服务使用F1免费套餐，这可能是原因吗？
