API Endpoints

GET /api/users

Get a list of users

{
  "message": "success",
  "data": [
    {
      "id": 1,
      "name": "admin",
      "email": "[email protected]",
      "password": "a66abb5684c45962d887564f08346e8d"
    },
    {
      "id": 2,
      "name": "user",
      "email": "[email protected]",
      "password": "4da49c16db42ca04538d629ef0533fe8"
    }
  ]
}

GET /api/user/{id}

Get user information by user id

{
  "message": "success",
  "data": {
    "id": 1,
    "name": "admin",
    "email": "[email protected]",
    "password": "a66abb5684c45962d887564f08346e8d"
  }
}

POST /api/user/

To create a new user based on POST data (x-www-form-url-encoded)

• name: User name
• email: User email
• password: User password

PATCH /api/user/{id}

To update user data by id, based on POST data (x-www-form-url-encoded)

• name: User name
• email: User email
• password: User password

You can send only one attribute to update, the rest of the info remains the same.

In this example, using CURL you can update the user email:

curl -X PATCH -d "[email protected]" http://localhost:8000/api/user/2

DELETE /api/user/{id}

To remove a user from the database by user id.

This example is using the curl command line

curl -X "DELETE" http://localhost:8000/api/user/2

The result is:

{"message":"deleted","rows":1}
