NGINX based access frequency limiting method and system

[0026] Such as figure 1 As shown, a specific implementation of the present invention:

[0027] 1. The user sends a request;

[0028] 2. nginx receives the user request;

[0029] 3. The lua script of nginx connects to the database, requests the current connection number s of this type, and adds 1 to the number or traffic; (if lua does not support the database, the data can be stored in the supported database)

[0030] 4. Obtain this type of request or traffic limit M according to the database;

[0031] 5. Determine whether the current connection number s is greater than the upper limit number M;

[0032] 6. If s> =M, intercept if the number of access restrictions is exceeded;

[0033] 7. If s

[0034] 8. Nginx sends the request to the back-end processing server through the reverse proxy;

[0035] 9. The background server processes and returns the results to the user;

[0036] 10. The database reduces the number of requests s by 1 or subtracts the flow value (this
