gmail quickstart.go will not retrieve a token about go-samples HOT 9 OPEN

I was having the same problem as well.

A workaround is to configure as stated in the instructions, then when running go run quickstart.go, follow the URL printed to stdout. That will lead you through the consent page and eventually redirect to localhost. That localhost call won't go anywhere, but if you copy the code={copy the value here}&state... from the URL into the terminal window and paste, it will complete the token request flow and the sample will list the labels as intended.

This isn't a long term solution and I'd encourage the Google folks to follow through on a more comprehensive fix.

This problem is also present in the calendar example, and I suspect many other too.

The reason is that the getTokenFromWeb function seems to implicilty rely on the out-of-band token transfer functionality which was removed for good in January 2023, as mentioned in #83. New clients seem to default to a http://localhost redirect URL, for which to work seamlessly the program would have to actively be listening on a port.

I happened to stumble upon exactly such listening implementation of this function in another repo. It's almost a drop-in replacement. One just needs to add a few imports, change the function name and pass the context, and it works!

Same problem with the Google Sheets example. Seems like a general problem, which is disappointing given this is intended to be learning material.

Did anyone have a better example?
