Go - GET HTTP Request with Query Parameters

In this source code example, we will show how to make an HTTP GET request call with query parameters in Golang.

Go - GET request with query parameters

Let's create a file named "go_example.go" and add the following source code to it.

package main

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

func main() {

    name := "Admin"
    occupation := "Engineer"

    params := "name=" + url.QueryEscape(name) + "&" +
        "occupation=" + url.QueryEscape(occupation)
    path := fmt.Sprintf("https://httpbin.org/get?%s", params)

    resp, err := http.Get(path)

    if err != nil {
        log.Fatal(err)
    }

    defer resp.Body.Close()

    body, err := ioutil.ReadAll(resp.Body)

    if err != nil {

        log.Fatal(err)
    }

    fmt.Println(string(body))
}

Note that the above example appends query parameters to the URL.

Run the following command to execute the go_example.go file: 

G:\GoLang\examples>go run go_example.go
{
  "args": {
    "name": "Admin",
    "occupation": "Engineer"
  },
  "headers": {
    "Accept-Encoding": "gzip",
    "Host": "httpbin.org",
    "User-Agent": "Go-http-client/2.0",
    "X-Amzn-Trace-Id": "Root=1-60d072dd-69515e203aad78b55270febd"
  },
  "origin": "103.208.69.12",
  "url": "https://httpbin.org/get?name=Admin&occupation=Engineer"
}
