Offset selectionChange Angular

由 我与影子孤独终老i 提交于 2019-12-07 11:34:25
I have a form which contains 1 drop-down list and 2 inputs. I have a drop down list which contains several objects. When I select one of them, I can retrieve the whole object and I am supposed to filled the two other inputs with the value from the selected object. However, it seems there is an offset when I do that. For instance I have an object banana in my list. If i select it nothing will happen. The 2 other inputs will not be filled at first.

Refresh token (JWT) in interceptor Angular 6

由 被刻印的时光 ゝ 提交于 2019-12-07 11:02:38
问题 Initially, I had a function that simply checked for the presence of a token and, if it was not present, sent the user to the login header. Now I need to implement the logic of refreshing a token when it expires with the help of a refreshing token. But I get an error 401. The refresh function does not have time to work and the work in the interceptor goes further to the error. How can I fix the code so that I can wait for the refresh to finish, get a new token and not redirect to the login
