Golang : http.Get example
Grabbing content in raw HTML format is useful for crawling or parsing purpose. This short tutorial demonstrates how easy it is to get the content of a website with http.Get()
function.
package main
import (
"fmt"
"io/ioutil"
"net/http"
"os"
)
func main() {
// http.Get() can handle gzipped data response
// automagically
resp, err := http.Get("https://golang.org")
if err != nil {
fmt.Println(err)
os.Exit(1)
}
defer resp.Body.Close()
htmlData, err := ioutil.ReadAll(resp.Body)
if err != nil {
fmt.Println(err)
os.Exit(1)
}
fmt.Println(os.Stdout, string(htmlData))
}
run this code and if everything goes well, you should see a bunch of HTML data being printed out.
NOTE : If you encounter crypto error regarding ssl connection, upgrade your Golang to latest version if problem persists, upgrade the certs on your machine
