How do I handle plain text HTTP Get response in Golang?

Question

I am making an HTTP GET request to an endpoint that returns a plain text response.

How do I grab the string of the plain text response?

My code looks like the following:

url := "http://someurl.com"  response, err := http.Get(url) if err != nil {     log.Fatal(err) } defer response.Body.Close() responseString := //NOT SURE HOW TO GRAB THE PLAIN TEXT STRING 

Answer 1

Response of the body can be read using any method that could read data from incoming byte stream. Simplest of them is ReadAll function provided in ioutil package.

responseData,err := ioutil.ReadAll(response.Body) if err != nil {     log.Fatal(err) } 

It will give you API response in []byte. If response is plain text you can easily convert it into string using type conversion:

responseString := string(responseData) 

And Check the result

fmt.Println(responseString) 

Sample Program:

package main  import (     "fmt"     "io/ioutil"     "log"     "net/http" )  func main() {     url := "http://country.io/capital.json"     response, err := http.Get(url)     if err != nil {         log.Fatal(err)     }     defer response.Body.Close()      responseData, err := ioutil.ReadAll(response.Body)     if err != nil {         log.Fatal(err)     }      responseString := string(responseData)      fmt.Println(responseString) }
