I have this function that basically uploads a video to YouTube. However, currently I am having to hard code the actual file path where the video is located(example: @"C:\Users\Peter\Desktop\audio\test.mp4";). I am wondering is there a way to make this more dynamic. For example right now I am using HTTP trigger, but how can the code be refactored to make it a Blob trigger? So that, when I upload a new .mp4 file into my blob storage container, this function would get triggered. 

I am asking this because, I planning to move this function to Azure portal and there, I won't be able to specify local file path there like I am doing right now. Thanks in advance.
