The invention provides an error information transfer and escape method, an error information transfer and escape device and an error information transfer and escape system. The method includes: receiving a message sent by a server side and subjecting the message to error parsing so as to obtain error information; subjecting the error information to escaping according to a predefined error conversion standard; recording the error information subjected to escaping to a conversion error message and returning the conversion error message. The error information transfer and escape method, the error information transfer and escape device and the error information transfer and escape system have the advantages that the problem in the prior art that error codes are difficult to transfer and apply is solved, and defining and transferring error information in large-scale enterprise-level IT (information technology) systems are facilitated, so that the purposes that the error information is parsed correctly and transferred accurately are achieved, and better customer experience and a more perfect error code transfer system are provided.
