General info

A microservice application created while writing a thesis entitled: "Functionality problems of monolithic architecture and microservices in web applications". Version in monolith architecture: https://github.com/NowakArtur97/My-Moments-Monolith.

Setup

To start the application, in the folder, enter the following commands in command line:

• docker-compose up -d
• docker-compose down

Use the login details provided above to generate the token or create new account by sending the appropriate request:

# POST /api/v1/registration
# Content-Type: application/json
{
    "username" : "user123",
    "password" : "Password1@",
    "matchingPassword" : "Password1@",
    "email" : "[email protected]"
}

The password must meet the following requirements:

• Must be between 6 and 30 characters long
• Passwords must match
• Mustn't contain the username
• Mustn't contain spaces
• Mustn't contain a repetitive string of characters longer than 3 characters
• Mustn't be on the list of popular passwords
• Must contain 1 or more uppercase characters
• Must contain 1 or more lowercase characters
• Must contain 1 or more special characters

Then generate JWT. The token can be generated using a username or email address. Password is required.

# POST /api/v1/authentication
# Content-Type: application/json
{
  "username": "user123",
  "password" : "Password1@"
}

Then use the token as a Bearer Token using e.g. Postman. Requests can be sent to the API Gateway address: http://YOUR_DOCKER_IP_OR_LOCALHOST:8989.
