Extracting ACCESS_TOKEN from Instagram redirect with Angular 5(Implicit Authentication)

问题

Since I'm developing a pure frontend app with no backend, I'm going with Instagram implicit authentication. The problem is, after the user authorizes the app, Instagram redirects to my redirect_uri with the access token like this, http://your-redirect-uri#access_token=ACCESS-TOKEN. How do I extract the access token from this? I tried using the router but with '#' it was not successful

回答1:

Use window.location.hash to access to all parameters starting from #. Or you can use window.location.href to access full URL. To get the token you can use window.location.hash.match(/#access_token=([^&]+)/)[1].

Note: If you are using TypeScript then you'd need to import window in your component.

declare let window;
