Call our API from Github pages

Problems: A Github page cannot call our API link from a different server
Solution:
- Modify your API file
- Append web.header('Access-Control-Allow-Origin', 'https://ntson2002.github.io')

class JccRreTagger:
    def POST(self):
        web.header('Access-Control-Allow-Origin', 'https://ntson2002.github.io')
