How to use dynamic IP agents to collect data? Web page data crawling refers to obtaining special content from the website without requiring the API socket of the website to obtain the content. As part of the customer experience of the website, web data information, such as text, images, noise, video and animation on the web page, are regarded as web data information, but in the whole process, if many applications of the same IP are operated repeatedly, it will certainly be limited. At this time, there must be the assistance of the application agent in order to maximize the efficiency and practical effect.

It is easy and interesting for programmers or developers to have the ability to write programs to enable them to build a web data crawler process. But for most people who don't have all the programming expertise, it's best to use some Internet crawler tools to get special content from specific web pages.

1. To get content from a dynamic website, the web page can be static or dynamic.

Generally speaking, the page you want to get will change with the time you visit the site. Generally speaking, this site is a dynamic web page that uses AJAX technology or other technologies to upgrade the page immediately. AJAX is a scripting technology for scheduled loading and multithreaded upgrades. Depending on the background management and a small amount of data transfer from the server virtual machine, you can upgrade a portion of a web page without reloading all web pages. The main performance is that when you click on an option in the web page, the URL of most websites remains the same; the web page is not fully loaded, only part of the data is loaded, there are certain changes.

2. Crawl hidden content from the web page.

Do you want to get special data information from the site, but if you open the connection or hover over a certain point, the content will appear? The website must be moved by the computer mouse over the selection to display information for classification, so that the function of the computer mouse to move to the connection can be set to crawl the hidden content in the web page.

3. Get the content from the endless flipped web pages.

When you flip to the bottom of the page, some of the data you need to get will always appear on some sites. For example, on today's headline home page, you have to constantly flip to the bottom of the page to load more articles, and endless flipping sites usually use AJAX or JavaScript to ask for additional content. In this case, you can set the AJAX request timeout setting and select the flipping method and flipping time to get the content from the web page.

4. Grab all the links from the web page.

The average website contains at least one hyperlink. If you want to get all the links from a web page, you can use the agent mobile app to get all the links posted on the page.
