proxy

Live Demo

• This app is running here: http://13.59.118.201:8080
• POST http://13.59.118.201:8080/short with URL in body as param to create a shorted code.
• GET http://13.59.118.201:8080/{code} to redirect to the original URL.

What must be done to run this project locally

• Define an env var called INSTANCE_IP with the IP from the local computer
  • There are some commands that you can use to find out your local IP address:
    • hostname -I | awk '{print $1}'
    • ip route get 8.8.8.8 | sed -n '/src/{s/.*src *\([^ ]*\).*/\1/p;q}'

Via Docker compose

• docker-compose up (pull the image from dockerhub)

Building locally

• Clone the project
• cd proxy
• mvn clean install
• Run:
  • java -jar target/app-0.0.1-SNAPSHOT.jar
  • Or you can use docker build to build your own image from the Dockerfile
    • docker run -p 8080:8080 your-image

How to test it

• Send a POST request to http://your-ip-here:8080/short, with the URL in the body of the request. It will return something like this:

{
"newUrl": "http://your-ip-here:8080/RANDOM_GENERATED_TEXT",
"expiresAt": 1595040333922
}

• Try to use some http client to perform the POST request. If you paste a complex URL in terminal, your text will be corrupted (some chars will be replaced in terminal) and your redirect will fail.
• Access http://your-ip-here/RANDOM_GENERATED_TEXT and you will be redirect to the recorded URL.

And what about the database?

This app uses a database in memory :)
