问题
I tried to lookup many answers from stackoverflow but couldnt find anything specific to this, I am implementing payment app and I want to display custom-tab in my app to record user visit by storing user-id, either by setting a cookie or using localstorage or by installing a service worker for the domain that custom tabs opens.
- Can a https page loaded in custom-tab write cookies that are also available when visiting the same page from Chrome?
- Is localstorage API available for my domain in custom-tab? if yes, is stored value available from Chrome?
- Is installing service worker allowed from Custom-tab? So I have access to S/W from Chrome browser?
If none of this possible, how could I record the visit from custom-tab and have it available in Chrome when user opens the domain from chrome browser?
Thanks in advance
回答1:
- Chrome Custom Tabs uses the same Cookie jar as Chrome. So, if a Cookie is created when a user accesses the page from a Custom Tab and Chrome is the Custom Tabs provider, it is also available when the user goes to the same domain from Chrome (outside Custom Tabs).
- Same as above.
- Yes, it is possible to install a service-worker from a Chrome Custom Tab.
You can check all the above by opening the URL that adds the cookie, install the service-worker or writes to the local store inside a Custom Tab, setup the device for debugging, connecting it to your computer and navigating to chrome://inspect/#devices in Chrome. Then choose the device and inspect the cookies, local storage, service-workers, etc.
