UserAgent and device, UserAgent Device

When a browser requests a webpage, A useragent (User Agent) is added before the url ).

PS: As a browser, you can do a lot of work on this useragent string. It can create many bugs or reduce many bugs. The only taste is yourself.

Let's talk about the distinction between Android phones and android pad ua.

Note: The ipad's pad ua is different from the android pad's pad ua, which is very obvious in some chrome versions.

If the useragent string contains "android", the website server identifies it as an android device for access. If the string contains "moblie, the website server considers it an android mobile phone to request a webpage. Otherwise, it considers it an android pad to request a webpage.
