Go-Captcha API

Server to generate and check captcha

This Captcha Generation is using "Inter Font© SIL OpenFontLicense 1.1"

Requirements

• Redis Server

How to Use

As example, you can start the go-captcha API like that:

export API_PORT=10888
export API_BIND=0.0.0.0
export LOGLEVEL=debug
export REDIS_SERVER=localhost:6379

go run init.go app.go

If you want to generate a captcha:

curl -X GET localhost:10888/api/captcha/v0

It will give you as result a PNG File and in the HTTP Response Header a "sessiontoken". This token you have to add to your CaptchaCheck Request:

curl -H 'sessiontoken: <token>' -X POST localhost:10888/api/captcha/v0/<token>

Thats it! Pretty easy.
