Parsing a Redis connection string for use with go-workers

redis_connection_string.go

package main

import (
	"fmt"
	"net/url"
	"strings"
)

func main() {
	s := "redis://username:[email protected]:6389/4?pool=25&process=2"

	u, err := url.Parse(s)
	if err != nil {
		panic(err)
	}

	config := getConfig(u)

	fmt.Println(config)
}

func getConfig(u *url.URL) map[string]string {
	config := map[string]string{
		"server":   u.Host,
		"database": strings.Trim(u.Path, "/"),
		"pool":     "30",
		"process":  "1",
	}

	for k, v := range u.Query() {
		config[k] = v[0]
	}

	pass, exists := u.User.Password()
	if exists {
		config["password"] = pass
	}

	return config
}

@henvo Password is sent via the *url.URL, more specifically the User field: https://golang.org/pkg/net/url/#URL

Redis (before version 6) does not have users, so the username is discarded.

If you are using Redis 6 with the ACL enabled then you’ll need to modify this snippet to also include the username.

Thanks so much for the answer!
