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

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)
}
