How to Manage Cookies in Go HTTP POST Requests for Website Login and Page Access?

Go HTTP Post and Use Cookies

Problem: Integrating cookies into a Go application to facilitate website login and subsequent page access.

Consider the following sample code:

func Login(user, password string) string {
    postUrl := "http://www.pge.com/eum/login"

    values := make(url.Values)
    values.Set("user", user)
    values.Set("password", password)

    resp, err := http.PostForm(postUrl, values)
    if err != nil {
        log.Fatal(err)
    }
    defer resp.Body.Close()

    // Store cookies here!
    return "Hello"
}

func ViewBill(url string, cookies) string {
    // Access page using cookies!
}

Solution: In Go, cookie management was introduced in version 1.1 via the net/http/cookiejar package.

Enhance your code with cookie handling capabilities:

import (
    "net/http"
    "net/http/cookiejar"
)

jar, err := cookiejar.New(nil)
if err != nil {
    // Handle error
}

client := &http.Client{
    Jar: jar,
}

This client adorned with the Jar implementation of the cookie jar can now store cookies for use during subsequent requests, facilitating smooth login and page navigation.
