可以通过注入 ILoggerFactory 和 ExecutionContext 实例来解决此问题。示例代码如下：

public static class Function1
{
    [FunctionName("Function1")]
    public static async Task Run(
        [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
        ILoggerFactory loggerFactory,
        ExecutionContext context)
    {
        // Use ILoggerFactory and ExecutionContext here
        ILogger logger = loggerFactory.CreateLogger("Function1");
        logger.LogInformation($"Function started in {context.FunctionAppDirectory}");

        return new OkObjectResult("Hello World");
    }
}

解决方法就是在函数中添加 ILoggerFactory 和 ExecutionContext 的实例作为参数，然后就可以正常使用了。
