阅读更多关于 Mocking a useragent in javascript?

Determine a user's timezone

阅读更多关于 Determine a user's timezone

问题 Is there a standard way for a web server to be able to determine a user\'s timezone within a web page? Perhaps from an HTTP header or part of the user-agent string? 回答1: -new Date().getTimezoneOffset()/60; The method getTimezoneOffset() will subtract your time from GMT and return the number of minutes. So if you live in GMT-8, it will return 480. To put this into hours, divide by 60. Also, notice that the sign is the opposite of what you need - it's calculating GMT's offset from your time

问题 How can I download a webpage with a user agent other than the default one on urllib2.urlopen? 回答1: Setting the User-Agent from everyone's favorite Dive Into Python. The short story: You can use Request.add_header to do this. You can also pass the headers as a dictionary when creating the Request itself, as the docs note: headers should be a dictionary, and will be treated as if add_header() was called with each key and value as arguments. This is often used to “spoof” the User-Agent header,

Get operating system info

阅读更多关于 Get operating system info

问题 I recently started wondering about sites like http://thismachine.info/ that get the user\'s operating system info. I have not been able to find out how to do that with PHP, and wanted to try to figure it out. I noticed that they list the user-agent , which gives lots of info about the browser. Do they get the operating system information from that, or from something else? Is there an API I could use to get the user\'s operating system? I see how they got the Browser and IP, but could not
