I have been reading the documentation of axios, Express, mongoose and other websites, however, nothing worked for

由 喜夏-厌秋 提交于 2021-01-28 12:14:05
问题 I'm using Ionic framework to build a hybrid mobile application and I have html5Mode set to true, Ui-Router, and gulp to provide me with livereload, sass compiling, css and javascript minifying. The problem is whenever I navigate to a state directly from the index, everything works fine, requests are being made to my server, but when I refresh that same state, I get Cannot GET error.
