Go - HTTP POST request FORM data

In this source code example, we will show how to send an HTTP Post request with form data in Golang.

Go - HTTP POST request FORM data

The PostForm issues a POST to the specified URL, with data's keys and values URL-encoded as the request body. The Content-Type header is set to application/x-www-form-urlencoded. 

The data is sent in the body of the request; the keys and values are encoded in key-value tuples separated by '&', with a '=' between the key and the value.

We send a POST request to the https://httpbin.org/post page.

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

package main

import (
    "encoding/json"
    "fmt"
    "log"
    "net/http"
    "net/url"
)

func main() {

    data := url.Values{
        "name":       {"Admin"},
        "occupation": {"Engineer"},
    }

    resp, err := http.PostForm("https://httpbin.org/post", data)

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

    var res map[string]interface{}

    json.NewDecoder(resp.Body).Decode(&res)

    fmt.Println(res["form"])
}

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

G:\GoLang\examples>go run go_example.go
map[name:Admin occupation:Engineer]
