How to Process Plain Text HTTP GET Responses in Golang?

Processing Plain Text HTTP GET Responses in Golang

When sending HTTP GET requests that return plain text responses, capturing the text can be a stumbling block. Here's a definitive guide on how to retrieve the plain text in Golang:

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)
}

要点:

1. Use ioutil.ReadAll: The 'ioutil' package provides a convenient function for reading data from an input stream. In this case, we use ioutil.ReadAll to read the entire response.
2. Convert to String: The data read from the response body is of type []byte. To obtain the actual plain text, we convert it to a string using type conversion.
3. Sample Program: The provided code demonstrates how to send an HTTP GET request, read and convert the plain text response, and print it to the console.

By following these steps, you can efficiently process plain text HTTP GET responses in Golang, enabling you to further work with the textual data as needed in your application.
