Preface

Recently, because I encountered a demand in my work, I need to do a batch import function, but there is no feedback status after running for a long time, which makes people look impatient and produce various assumptions! In order to solve the mental disorder, I wrote this function.

Through the thread implementation of the import, and the state of being executed in session, both sharing the implementation of the state, through ajax call session implementation of the state, so as to achieve feedback into the state of the function!
