Information processing method and device

The invention provides an information processing method and device, a security check mechanism is added on the basis of an existing application framework. Specifically, the method comprises the steps:after a service application side receives a request message sent by a client side, employing a message converter in a request parser for processing the request message, and obtaining a processing result is obtained; performing security check on the processing result by using a request checker in a request parser; after the verification is passed, performing service logic processing and generatinga response message; and packaging the response message, and returning the packaged message to the client. Due to the fact that the information, namely the request message, transmitted between the client side and the service application side is subjected to safety verification, man-in-the-middle attacks mainly aiming at data transmission between the client side and the service application side canbe avoided.
