GreenCityUBS

1. About the project

The main aim of “GreenCity” project is to teach people in a playful and challenging way to have an eco-friendly lifestyle. A user can view on the map places that have some eco-initiatives or suggest discounts for being environmentally aware (for instance, coffee shops that give a discount if a customer comes with their own cup). А user can start doing an environment-friendly habit and track their progress with a habit tracker. "GreenCityUBS" is a microservice which contains garbage collection service.

2. Where to find front-end part of the project

spring.datasource.username=${DATASOURCE_USER}
spring.datasource.password=${DATASOURCE_PASSWORD}
spring.mail.username=${EMAIL_ADDRESS}
spring.mail.password=${EMAIL_PASSWORD}
cloud.name=${CLOUD_NAME}
api.key=${API_KEY}
api.secret=${API_SECRET}
google.clientId=${GOOGLE_CLIENT_ID}
spring.rabbitmq.host=${RABBITMQ_HOST}
spring.rabbitmq.password=${RABBITMQ_PASSWORD}
spring.rabbitmq.username=${RABBITMQ_USERNAME}

4.3. How to work with Viber bot locally.

1. You can find a quick instruction here: https://www.youtube.com/watch?v=_ORUSRJGXmk&list=PLcaYXHLmxz8nJByvtOoIBr8FnSS9CY1JD&index=23&t=37s

4.4. How to work with swagger UI in our project

1. Run GreenCityUBS project (look up paragraph How to run).

2. Run GreenCityUser project (look up paragraph How to run).

3. Use the following link to open Swagger UI: http://localhost:8060/swagger-ui.html#/

4. Use POST method with /ownSecurity/signUp to create an account. If you set a valid email credentials, you should receive an email with verification link. Verify the registration by following that link. We highly recommend to use gmail, it's free of charge and easy to get going: how to allow email sending from gmail, Google client id. Alternatively you can drop a record in verify_email table on your local database. First you should update user role : UPDATE users SET role = 1 WHERE id = your_user_id;. After this DELETE FROM verify_emails WHERE user_id = your_user_id;

5. Use POST method with /ownSecurity/signIn to sign in. After entering the credentials you should receive access and refresh tokens.

6. Copy the given access token and put it into GreenCityUBS(http://localhost:8050/swagger-ui.html#/) Authentication Header. Press Authorize button.

   

   Insert the given token into input field. The scheme should be like this <given_token>. Press Authorize button.

   

7. Now you can use swagger UI to test REST API. Some controllers require ADMIN role. By default, new registered users have role USER. To overcome this you need to update record that corresponds to your user in the local database. For example, UPDATE users SET role = 1 WHERE id = <your_user_id>.

4.5. Connect with front-end

There is no special configurations required. Just clone GreenCityClient and run it. If you want to sign in with Google account, it's mandatory to set google.clientId. Read more about how to obtain Google client id, it's free.
