Golang : Convert HTTP Response body to string
Problem :
While writing tutorial on how to interface with PayPal's IPN(Instant Payment Notification), I need to convert the HTTP Response body to string for verifying the IPN. So how to convert the response body to string ?
Solution :
Use ioutil.ReadAll(resp.Body)
function to read all the body and convert to string with string()
function.
package main
import (
"fmt"
"io/ioutil"
"net/http"
"os"
)
func main() {
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) //<--- here!
if err != nil {
fmt.Println(err)
os.Exit(1)
}
// print out
fmt.Println(os.Stdout, string(htmlData)) //<-- here !
// use Regular Expression to search for keyword
// for example
verified, err := regexp.MatchString("VERIFIED", string(htmlData))
//if err != nil {
// fmt.Println(err)
// return
// }
}
