Application example of crawling blog data using java jsup
•
Java
Import Maven dependencies
Select the website you want to crawl (here I take crawling my own blog posts as an example)
Enter this web site through a browser
Like my blog
Use the browser debugging tool (this purpose will be mentioned later)
Write the corresponding java code
The above code can be sorted out as follows:
Connect the crawling website - > set the browser request header (to prevent crawling data failure due to browser restrictions) - > get the whole HTML (actually an HTML) - > select an element in the HTML (such as class selector posttitle2. If the corresponding element selector is not specified, the whole HTML will be directly crawled) - > crawl the data and output it
The output results are shown in the figure below:
