percook: persistent cookiejar

percook makes any http.CookieJar implementations persistable.

This library requires Go 1.9 because using sync.Map.

This project was frozen!

Because some implementation of http.CookieJar Cookies(*url.URL) method (e.g. net/http/CookieJar) returns http.Cookie with Name & Value only, I must write up code infering Domain, Path and Expires. I finally wrote code can infer Domain and Path in percook.go (please see CookieJar.AllCookies() method), but there are no way to get Expires.

I started this project because I don't like to use libraries forked from standard libraries, but I currently accept net/http/CookieJar forked libraries. It's required to implement.

:(

Usage

Here is example with https://httpbin.org/'s Cookies endpoints.

package main

import (
	"fmt"
	"net/http"
	"net/http/cookiejar"

	"github.com/otofune/go-percook"
)

func panicGet(c *http.Client, url string) {
	if _, err := c.Get(url); err != nil {
		panic(err)
	}
}

func main() {
	httpJar, err := cookiejar.New(&cookiejar.Options{})
	if err != nil {
		panic(err)
	}
	pjar := percook.New(httpJar)
	client := http.Client{Jar: pjar}

	panicGet(&client, "https://httpbin.org/cookies/set/abc/123")
	panicGet(&client, "https://httpbin.org/cookies/set/edf/123")
	panicGet(&client, "https://httpbin.org/cookies/set/will_be_removed/100")
	panicGet(&client, "https://httpbin.org/cookies/delete?will_be_removed=")

	for u, cookies := range pjar.AllCookies() {
		for _, cookie := range cookies {
			fmt.Printf("%s: %s\n", u.String(), cookie.String())
		}
	}
}

Output expected:

$ # output
$ go run ./examples/readme
http://httpbin.org/: abc=123
http://httpbin.org/: edf=123
$
