How to put a web page with data retrieved from the backend to Github and preview it?

Question

I wrote a project using Vue myself, and the back-end API is official Douban. I package and compile the project, and then push it to github for preview. You can only see pure front-end things. The specific situation is: the circle keeps spinning, and you can't get the background data at all. I want to fully display my project. Excuse me...

How do you call Douban’s backend API? Is it through a proxy?
