Network message analysis method capable of configuring message format confidentiality by user

The invention belongs to the field of network message analysis, and particularly relates to a network message analysis method capable of configuring message format confidentiality by a user. The method comprises the following steps: (1) standardizing and defining a message data field: referring to an actual network communication message format, and defining a message configuration file with universality; fixing communication protocol head structure information in the message configuration file, and defining and standardizing a message data format which needs to be filled by a user; (2) adding a message format configuration file; (3) constructing a bitwise message analysis algorithm; and (4) receiving message data, and calling the bitwise message analysis algorithm constructed in the step (3) to perform bitwise reading. According to the invention, the problem that the system development and maintenance cost is increased due to the fact that confidential messages cannot be provided for developers and communicat
