In today’s era of big data, the work of collecting data has become particularly important. Usually, we can’t achieve the required amount of data collection using human resources. So many web workers use crawler tools. What should we do with crawler tools? How about efficient use? Here is a detailed introduction to the relevant information.
1. An efficient crawler system
is required. Usually, when we collect data, the choice of crawler system is also very important. When crawling information, crawlers need a good network environment and a stable computer system. Collecting data in a slow network environment will not efficiently complete the collection work. Secondly, the proxy server is generally unstable, so the crawler must establish a corresponding fault tolerance mechanism to achieve efficient data collection.
2. Crawlers must break through the restriction of access frequency.
Generally speaking, websites will set up various anti-crawler strategies. For example, when a website finds the same IP address during detection, it will be considered as a crawler program. The crawler program cannot continue to work; it will be blocked. For the anti-crawling strategy of the website, the crawler wants to break the access restriction to use the proxy IP to prevent such problems. After the proxy IP is used, every time The IP addresses displayed when crawling information are all different, so that we can easily avoid website detection and keep the work going.
In general, the efficient use of crawler proxy IP can increase our work efficiency and ensure the efficient operation of data collection. You can learn the above two methods to use.
