The invention discloses a mobile device attribute detection method based on a reverse agent, and relates to the field of mobile device detection. The method comprises the steps that: while receiving aclient request, a reverse agent server reads a mobile device attribute information project list required by a rear-end internet server through reverse agent server configuration information; a required mobile device attribute list project and mobile device User Agent information are transmitted to a User Agent module to process; and, after the User Agent module completes request processing, the reverse agent server forwards a processed user request to the rear-end internet server. According to the method in the invention, a special third-party server is not required for providing a mobile device attribute information detection service any longer; therefore, the operation cost is effectively reduced; simultaneously, the interaction waiting process with the third-party server is reduced; the waiting time of a user is reduced; and thus, the user experience of a mobile internet user is effectively improved.
