如何在Golang中处理纯文本HTTP Get响应？

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)
}
