HTTP (Hyper Text Transport Protocol) message rule matching method, system, equipment and medium

The invention discloses an HTTP (Hyper Text Transport Protocol) message rule matching method, system and device and a medium, and the method comprises the steps: analyzing an obtained HTTP message, and obtaining an analyzed HTTP message; a configuration file used for HTTP message rule matching is read and analyzed, and a user-defined rule set is generated; the Head part is extracted, and extraction information is obtained; performing character string matching on the body part according to a user-defined rule set based on an improved multimode matching algorithm of an AC automaton; recording the occurrence frequency and position of the matched character string in the body part information in each matching rule; determining a preliminary matching result according to the extraction information and a multimode matching result; performing position matching operation on the preliminary matching result according to the position information to obtain an accurate matching result, namely an HTTP message rule matching r
