Complete Golang Gin login page with Recaptcha and JWT

Installation

Get your recaptcha keys:

• Visit https://www.google.com/recaptcha/admin#list
• Add a label (e.g. "example.com's recaptcha")
• Add domains (e.g. "127.0.0.1" and/or "example.com")

Now you have a "site key" and a "secret key".

On your console, set the environment variables:

$ export RECAPTCHA_SECRET=your-google-recaptcha-secret-key
$ export GLOBAL_SIGNING_KEY=your-supersecret-signing-key
$ export SERVER_DOMAIN=127.0.0.1
$ export SERVER_PORT=:8080 # ":8080" in debug mode; "" in production
$ export SSL_ENABLED=false # false in debug mode; true in production

Inside login.html (line 140), add your site key (data-sitekey) value.

Inside main.go, inside the checkLoginCredentials function, add a call to your db to validate the user and password.

Run

go run main.go
