browser version detection from server side with java

问题

I saw many posts related to the browser detection, User agent detection etc...I want to detect the version from server side and send appropriate data based on that.

I know browsers can mimic version with tools, but that doesn't matter for me.

I need the java solution for the exact version detection.

回答1:

Take a look at user-agent-utils.

回答2:

Here is the code explaining how to do it using user-agent-utils:

String userAgent = req.getHeader("user-agent");
UserAgent ua = UserAgent.parseUserAgentString(userAgent);
Version browserVersion = ua.getBrowserVersion();
String browserName = ua.getBrowser().toString();
int majVersion = Integer.parseInt(browserVersion.getMajorVersion());

回答3:

Check the headers in the HTTP servlet request - they'll tell you. Check the "User-Agent" header.

回答4:

I recommend UA Detector at uadetector.sourceforge.net

回答5:

Use Spring Mobile Device Module?

This can use either the LiteDeviceResolver or the WurflDeviceResolver.
