Azure函数依赖注入再次失败

Question

我有一个在Azure中运行的Azure V2应用程序。在各种发行版中，这大约是第三次了，我的自定义依赖项注入再次失败了！

这一次比以往任何时候都糟，因为仅当将问题部署到Azure且日志记录是噩梦才能查明正在发生的情况时才会发生。

Azure Functions当前正在按以下方式运行，但出现通常的错误，即无法索引我的Function。

我的本地版本可以正常运行，如下所示

[您可以看到我在本地使用与Azure相同的运行时版本，因此，如果有人知道为什么我的依赖注入将在本地运行，但在部署时不行，将不胜感激。

我正在使用Autofac 4.8.1作为我的依赖项注入容器。

提前感谢。

BTW如果其他任何人都无法解决其功能主机为何无法启动的问题，请遵循以下说明。

• 进入门户以使用Azure功能并找到并启用实时日志流。
• 虽然此窗口处于打开状态，但重新部署/发布您的应用程序。
• 完成后，进入云资源管理器（仅Visual Studio Windows：/）并找到日志。

如果您在部署时没有打开实时日志流窗口，则不会收到任何日志！！

我已经创建了一种在Azure Functions v3项目中使用Autofac DI的新方法，而无需使用静态函数或注入属性。使用适当的范围调用服务的处置。

示例

public class Function1 
{
    private readonly IService1 _service1;

    public Function1(IService1 service1)
    {
        _service1 = service1;
    }

    [FunctionName(nameof(Function1))]
    public async Task Run([QueueTrigger("myqueue-items", Connection = "AzureWebJobsStorage")]string myQueueItem, ILogger log)
    {
        ...
    }
