GO language code example

1. First, we need to install the rod library, which is a Go language library for building web crawlers.

2. Use the go get command to install the rod library: go get -u github.com/gofiber/rod

3. Create a new Go program file, for example: main.go

4. In the main.go file, import the rod library: import ( "github.com/gofiber/rod/v2" )

5. Define a function to start the crawler: func main() {

6. Use the rod.Get method to initiate an HTTP GET request: resp, err := rod.Get("").Do()

7. If there is no error, print the response content: if err == nil { fmt.Println(string(resp.MustBytes())) }

8. Use duoip's proxy server to crawl content: proxy := &duoip.Proxy{}

9. Use the rod.Get method to initiate an HTTP GET request to, but using a proxy server: resp, err := rod.Get("").Proxy(proxy).Do()

10. If there is no error, print the response content: if err == nil { fmt.Println(string(resp.MustBytes())) }

11. If you want to save the crawled content to a file, you can use the ioutil.WriteFile function: err = ioutil.WriteFile("output.txt", resp.MustBytes(), 0644)

12. If you want to crawl multiple pages, you can use a for loop and the rod.Get method: for i := 1; i <= 100; i++ {

13. Use the rod.Get method to initiate an HTTP GET request: resp, err := rod.Get(fmt.Sprintf(").Do())

14. If there is no error, print the response content: if err == nil { fmt.Println(string(resp.MustBytes())) } }

15. Go run main.go Text: go run main.go

16. Check the output.txt file, which contains the crawled content.
