以编程方式检查网站是否有移动版本。 （Python的/ PHP）

Question

Lets say i have a incoming website request with a url of desktop version of website. I'd like to detect if this website has a mobile version.

According to this answer Fetch website mobile version? most of what i have to do is to set User Agent to some mobile phone and server will serve the mobile version.

I think i could also check m.domain.com and mobile.domain.com.

But here's question:
How would i know if server responded with mobile version?
Are there other ways of getting mobile version?

Answer 1

I don't believe there is a one size fits all answer to your question. You could use curl to hit the domain with a couple different user agents and see if different content is returned for mobile vs desktop, or see if you are redirected for either.
