Network Anomaly Data Detection Method and Device as well as Computer Equipment and Storage Medium

A computer equipment, comprising a memory and one or more processors, wherein computer readable instructions are stored in the memory;

• and when the computer readable instructions are executed by the one or more processors, the one or more processors execute the following steps:
• receiving access request data transmitted by a client;
• searching historical access request data corresponding to a user session identifier in the access request data;
• acquiring a header character string of the access request data;
• performing word segmentation processing on the header character string according to a preset step length so as to obtain a word segmentation set;
• obtaining a word segmentation weight matrix according to the historical access request data and the word segmentation set;
• inputting the word segmentation weight matrix into an anomaly data detection model so as to obtain a data anomaly probability;
• and
• judging whether anomaly data exists in the header character string according to the data anomaly probability.

One or more nonvolatile computer readable storage media stored with the computer readable instructions, wherein when the computer readable instructions are executed by one or more processors, the one or more processors execute the following steps:

• receiving access request data transmitted by a client;
• searching historical access request data corresponding to a user session identifier in the access request data;
• acquiring a header character string of the access request data;
