prime_number

How to use

• Download/clone the project then import Prime_Number_Service.postman_collection.json file to your Postman Collection

• Edit environment variable in postman: set var SERVER into ec2-13-229-81-27.ap-southeast-1.compute.amazonaws.com:8000 or 13.229.81.27:8000

• You can try to call this API: {{SERVER}}/v1/health

• If you can see response like this, server is working properly: {"status": "ok"}

• Call this API to get token, almost every APIs require token to work: {{SERVER}}/v1/users/token

• APIs explain:

  • POST | {{SERVER}}/v1/users | create a new user
  • GET | {{SERVER}}/v1/users | get all users
  • GET | {{SERVER}}/v1/users/:id | get specific user
  • PUT | {{SERVER}}/v1/users/:id | edit user's info
  • DEL | {{SERVER}}/v1/users/:id | delete user (only admin can do this action)
  • POST | {{SERVER}}/v1/requests | create a prime number request (edit any number you want in the field e.g. {"send_number": 123})
  • GET | {{SERVER}}/v1/requests | get all requests
  • GET | {{SERVER}}/v1/requests/:id | get all requests by a user

• About profiling, you can go to http://13.229.81.27:6060/debug/pprof to take a look at server's profiles

• About metrics, you can go to http://13.229.81.27:6060/debug/vars to see the debug server

• About tracing, you can go to http://13.229.81.27:9411/zipkin to observe all the traced requests
