Method for acquiring data information of security device by using web crawler technology

The invention belongs to the technical field of computer software, and particularly relates to a method for acquiring the data information of a security device by using a web crawler technology. The method comprises the following steps of sending an acquisition request to a to-be-acquired page, setting the entity parameters related to login of the to-be-acquired page by using an exchange method in a RestTemplate tool, linking the page through the RestTemplate tool and performing simulated login, linking to the to-be-collected webpage, calling a preset entity parameter by the RestTemplate tool to carry out login authentication operation, crawling webpage data after login and storing the webpage data in a local database, and finally carrying out statistics on the data in the local database and displaying the data to a front-end page.Through the mode, the identity authentication limitation is bypassed; and by acrawler technology, the wanted data information can be crawled without identity login authentication, a
