How to gen this kind of url , https://google.com/share.google?q=xxx

I got some from my spam mail, it used to do redirect

https://share.google/BrsHdzd8MTtFBZ9QM

On the Google results page, select the three dots next to the result, then select "Share". It'll generate a new URL each time you use the Share link.

If you need the google.com format rather than share.google, you can use the same code in both formats.
