Problems solved by technology

[0005] In the existing technology, there are many technologies in the crawler field, but the function of each technology is too single, and the automation of the crawler and the data persistence of the crawler are relatively lacking, but after the crawler obtains the data, the user needs to further filter And processing, the efficiency is low, and it needs to consume a lot of manpower when it is applied to large-scale database establishment and periodic tasks
[0006] For the above-mentioned problems existing in related technologies, no effective solution has been found yet

Abstract

The embodiment of the invention provides a method and a device for acquiring external data by using a crawler. On one hand, the method comprises the following steps: acquiring a data acquisition instruction according to a trigger condition; calling a crawler program according to the data acquisition instruction; receiving a crawler page captured by the crawler program; and analyzing the crawler page to obtain result data, and storing the result data in a mysql database. Through the method and the device, the technical problem that a crawler program cannot be automatically called to obtain datain the prior art is solved, the efficiency of capturing the data by using a crawler is improved, and manual operation is reduced.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of computers, in particular to a method and device for acquiring external data by using a crawler. [0003] 【Background technique】 [0004] In the prior art, a crawler is a program or script that automatically captures information on the World Wide Web according to certain rules. A crawler is currently the most common and important means for all companies to obtain external data, and it can play a very good role in business data. supplementary effect. [0005] In the existing technology, there are many technologies in the crawler field, but the function of each technology is too single, and the automation of the crawler and the data persistence of the crawler are relatively lacking, but after the crawler obtains the data, the user needs to further filter And processing, the efficiency is low, and it needs to consume a lot of manpower when it is applied to large-scale database establishment and periodic tasks....
