go-app

This repository hosts Golang microservices for an API gateway, investment accounts service, and customer data service. The repository is currently in development.

Usage

Build Docker Images

To build the Docker images for each service:

docker build -t customers-service -f path/to/Dockerfile.customers .
docker build -t gateway-service -f path/to/Dockerfile.gateway .
docker build -t invest-accounts-service -f path/to/Dockerfile.invest-accounts .

To run each service container:

docker run -d -p 8080:8080 customers-service
docker run -d -p 8081:8081 gateway-service
docker run -d -p 8082:8082 invest-accounts-service

Testing the API:

Authorization

curl -X POST http://localhost:8081/login `
  -H "Content-Type: application/json" `
  -d "{\"username\": \"admin\", \"password\": \"password\"}"

Replace with the actual JWT token obtained from the previous step

# Example GET request to fetch customer data
curl -X GET http://localhost:8081/customer `
  -H "Authorization: Bearer $TOKEN"

# Example POST request to create a customer
curl -X POST http://localhost:8081/customer `
  -H "Authorization: Bearer $TOKEN" `
  -H "Content-Type: application/json" `
  -d "{\"name\": \"V N\", \"email\": \"v.n@example.com\"}"

# Example PUT request to update a customer
curl -X PUT http://localhost:8081/customer/1 `
  -H "Authorization: Bearer $TOKEN" `
  -H "Content-Type: application/json" `
  -d "{\"name\": \"Updated Name\"}"

# Example DELETE request to delete a customer
curl -X DELETE http://localhost:8081/customer/1 `
  -H "Authorization: Bearer $TOKEN"

Use the following curl commands to interact with the API:

• Retrieve all customers:

curl -X GET http://localhost:8081/customer

• Retrieve a specific customer (e.g., customer with ID 4):

curl -X GET http://localhost:8081/customer/4

• Create a new customer:

curl -X POST \
  http://localhost:8081/customer \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Name",
    "surname": "Surname",
    "age": 30,
    "phone_number": "1234567890",
    "debit_card": "1234-5678-9101-1121",
    "credit_card": "5432-1098-7654-3210",
    "date_of_birth": "1994-05-20T00:00:00Z",
    "date_of_issue": "2023-01-15T00:00:00Z",
    "issuing_authority": "Authority XYZ",
    "has_foreign_country_tax_liability": false
  }'

• Update an existing customer (e.g., customer with ID 7):

curl -X PUT \
  http://localhost:8081/customer/7 \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Updated Name",
    "surname": "Updated Surname",
    "age": 35,
    "phone_number": "9876543210",
    "debit_card": "5678-9101-1121-3141",
    "credit_card": "8765-4321-0987-6543",
    "date_of_birth": "1990-08-15T00:00:00Z",
    "date_of_issue": "2020-03-10T00:00:00Z",
    "issuing_authority": "Authority ABC",
    "has_foreign_country_tax_liability": true
  }'

• Delete a customer (e.g., customer with ID 7):

curl -X DELETE http://localhost:8081/customer/7

• Retrieve all investment accounts:

curl -i http://localhost:8081/invest-account

• Retrieve a specific account (e.g., account with ID 1):

curl -i http://localhost:8081/invest-account/1

• Create a new account:

curl -i -X POST http://localhost:8081/invest-account -H "Content-Type: application/json" -d "{\"owner_id\": \"1\", \"client_survey_number\": \"12345678\", \"share\": 100, \"invested_amount_of_money\": 5000.0, \"free_amount_of_money\": 2000.0}"

• Update an existing account (e.g., account with ID 7):

curl -i -X PUT http://localhost:8081/invest-account/7 -H "Content-Type: application/json" -d "{\"owner_id\": \"1\", \"client_survey_number\": \"87654321\", \"share\": 150, \"invested_amount_of_money\": 6000.0, \"free_amount_of_money\": 2500.0}"

• Delete an account (e.g., account with ID 1):

curl -i -X DELETE http://localhost:8081/invest-account/1
