Update ionic framework cause CORS


#1

I have update my ionic from 3.7.0 to 3.8.0
In 3.7.0, I can GET/POST/PUT my server api .
But after update to 3.8.0, I can’t and receive the console log below:

ERROR: {"_body":{"isTrusted":true},"status":0,"ok":false,"statusText":"","headers":{},"type":3,"url":null}

Anyone know what happen? Thanks a lot.
