问题 I have been trying to make a post request to my backed API to post some data. I have tried this API using postman and it works fine and the data is returned properly.

问题 I am attempting to use some code I found on https://github.com/bevacqua/dragula/issues/289#issuecomment-277143172 to my Ionic project.
