Network exceptions

[henry-hz]

Dear @o1298098 ,
let me suggest a complete and robust Network communication module used under Fish in this repo: https://github.com/bozaigao/fish-redux-demo .

I think that it could even inspire us to create a lib for network using the patterns found there.
cheers

Thank you for your suggestion, I will improve network exceptions, all API requests will return a base class, including status code， data and exception information
