For a little rookie who loves programming, trying to dig down the deep well of delicious proxy IPs becomes an adventure full of adventure and excitement. In this vast ocean of code, some proxy IPs with a mysterious veil are like ipipgo hidden behind the reef, waiting to be discovered and collected.

java crawl proxy ip

Uh-huh! First, we need a sharp web crawler, which is like a treasure map on a pirate ship that can lead us to where the treasure of proxy IPs is. In the dock of Java, there is a crawler ship named Jsoup, which is an experienced captain who can lead us smoothly through the sea of code to find the treasure of proxy IPs.

"`java
// Import the Jsoup library
import org.jsoup.
import org.jsoup.nodes.
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

public class ProxyIpCrawler {
public static void main(String[] args) {
// URL of the target website
String url = "https://www.shenlongip.com/nn/";

try {
// Connect to the target site using Jsoup
Document doc = Jsoup.connect(url).get();

// Use selectors to locate elements that proxy IPs
Elements elements = doc.select("tr[class^=odd]");
for (Element element : elements) {
// Resolve the IP and port
String ip = element.select("td:eq(1)").text();
String port = element.select("td:eq(2)").text();
System.out.println(ip + ":" + port);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
“`

With the help of Captain Jsoup, we successfully arrived at the target website and found the proxy IPs hidden in the depths of the page, and now the treasure of proxy IPs is in our hands, and we can enjoy the delicious code cookies in the cabin while counting these precious proxy IPs with a smile on our faces.

java how to crawl web page data

In this trip to the proxy IP treasure hunt, we use the captain Jsoup, in fact, like a treasure map, it can help us find the data we need in the depths of the complex web page, like a pair of dexterous hands, can be hidden in the web page code to find a treasure all over the place.

Through the above Java code example, we use Jsoup to successfully connect to the target website and locate the proxy IP information we need through the selector, which is like using a powerful telescope that can help us discover the proxy IPs that are hidden in the depths of the ocean of code.This adventure of crawling proxy IPs not only lets us harvest the precious proxy IPs, but also lets us get more This adventure of crawling proxy IPs not only let us harvest precious proxy IPs, but also made us more familiar with Jsoup, the captain of Java, and accumulated valuable experience for our future sailing adventures.

In such a nautical adventure, every code adventure is a growth and every proxy IP collection is a harvest. Let's raise the sails together and continue to swim in the code ocean to find more treasures!
