[0003] However, with the continuous development and updating of browsers and mobile terminal brands, the update speed of UA library files has been far behind the speed of browser and mobile terminal brand development and update. Therefore, users cannot be accurately identified through UA strings. Due to the type of device or browser held, it is impossible to render the interface for the user in a more beautiful and reasonable way during the web development process, so that targeted marketing cannot be carried out according to the user's behavior habits

Embodiment Construction
[0046] In the existing implementation, when the UA string is adapted to the UA library file to accurately identify the type of user equipment and browser, the more comprehensive the equipment information in the UA library file, the more accurate the identification of the user equipment and browser type. is more accurate. Among them, UA (UserAgent, user agent) is a part of the Http protocol, which is a part of the header field. It is a special string header. The server can identify the operating system, version, and CPU type used by the client according to the UA string. , browser and version, browser rendering engine, browser language, browser plug-in, etc.
[0047] At present, the more common UA library file is the WURFL library file. The WURFL library file is a standard XML file, which is an open-source free XML file, which collects the technical parameters of most mainstream mobile devices in the world. Ordinary users can only read but not write, resulting in a large num...

The invention provides a UA identification method comprising the following steps: acquiring an UA identifier sent by a terminal; carrying out UA identifier adapting in a default UA database; when UA identifier adapting in the default UA database fails, carrying out adapting through a custom UA database; if adapting succeeds, returning corresponding adapting information; and if adapting fails, parsing the UA identifier, and saving the parsed adapting information to the custom UA database for next adapting after parsing succeeds. Through the technical scheme of the invention, adapting information in the default UA database can be complemented, and therefore, the identification rate of the terminal is improved.
Description
technical field [0001] The present application relates to the field of communication technology, and in particular to a UA identification method and device. Background technique [0002] In the process of developing a web page on a mobile terminal, it is usually necessary to accurately identify the type of user equipment and browser, so as to render different interfaces for different users. At present, the common way to identify the type of user equipment and browser is to obtain the UA (UserAgent, user agent) string in the browser request, and then pass the obtained UA string with the UA library file, such as WURFL (WirelessUniversalResourceFile, Wireless Universal Resource File) library files are adapted to achieve. [0003] However, with the continuous development and update of browsers and mobile terminal brands, the update speed of UA library files has been far behind the speed of browser and mobile terminal brand development and update. Therefore, users cannot be accu...
