How to Handle Plain Text HTTP GET Responses in Go?

Handling Plain Text HTTP GET Responses in Go

When making an HTTP GET request to an endpoint that returns a plain text response, retrieving the text can be achieved through a combination of the ioutil package and type conversion.

In your given code:

url := "http://someurl.com"

response, err := http.Get(url)
if err != nil {
    log.Fatal(err)
}
defer response.Body.Close()

The response body contains the plain text response, but it is in the form of a byte array. To obtain the string representation, use the ioutil.ReadAll function to read the entire body into a []byte slice:

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

Finally, since the response is plain text, it can be easily converted to a string using type conversion:

responseString := string(responseData)

This completes the process of handling plain text HTTP GET responses in Go. The resulting responseString variable now contains the plain text response as a string.

Example Program:

package main

import (
    "fmt"
    "io/ioutil"
    "log"
    "net/http"
)

func main() {
    // HTTP GET request
    url := "http://country.io/capital.json"
    response, err := http.Get(url)
    if err != nil {
        log.Fatal(err)
    }
    defer response.Body.Close()

    // Retrieve plain text response
    responseData, err := ioutil.ReadAll(response.Body)
    if err != nil {
        log.Fatal(err)
    }
    responseString := string(responseData)

    // Print result
    fmt.Println(responseString)
}
