Create a **Google Cloud Platform project**. Follow the [Google guide](https://cloud.google.com/resource-manager/docs/creating-managing-projects). 46 | 47 | 2. Create a **service account** and create **JSON credentials** for it. Follow the [Google guide](https://developers.google.com/workspace/guides/create-credentials) (see the _"Service account credentials"_ section). When you create the service account, under "select a role" choose `Pub/Sub Admin` and `Firebase Admin` (note: for production use, you may want to restrict these to lower roles, needs to be tested). 48 | 49 | 3. Once you have the JSON credentials, place them in the following directories, under the name 'PRIVATE.json': 50 | 51 | - device-service/credentials/PRIVATE.json 52 | - websocket-service/credentials/PRIVATE.json 53 | - user-service/credentials/PRIVATE.json 54 | - transaction-service/credentials/PRIVATE.json 55 | 56 | > Note: you can use the same service account and the same JSON credentials file in all places, or you can create separate ones for extra security if you want 57 | 58 | 4. Create a Cloud Firestore database Follow the [Google guide](https://firebase.google.com/docs/firestore/quickstart) 59 | 60 | 5. In the **docker-compose.yml** file, replace `chargerevolutioncloud` name with the **project id** of your own GCP project. 61 | 62 | 6. Install docker and docker-compose if you haven't already 63 | 64 | > If you are deploying on a remote machine or VPS, **open** up port `3000` and port `5000` so you can access the app remotely from your own machine. 65 | > Important: For actual deployment you should add a reverse proxy layer or some other security measure to protect your open port. A good place to start: [How To Deploy a Go Web Application with Docker and Nginx on Ubuntu 18.04](https://www.digitalocean.com/community/tutorials/how-to-deploy-a-go-web-application-with-docker-and-nginx-on-ubuntu-18-04) 66 | 67 | 7. Build and run the app on your machine (or VPS) 68 | 69 | docker compose up --build 70 | 71 | 8. The device service should now be running on `localhost:5000`. Use Postman or some other tool to send a post request and create a charging station (API description: [swaggerhub.com](https://app.swaggerhub.com/apis/gregszalay/ocpp_device_service/v2.0.0)) For example, you can send something like this in the request payload: 72 | 73 | POST: `localhost:5000/chargingstations/create` 74 | 75 | { 76 | "id": "CS123", 77 | "serialNumber": "5", 78 | "model": "CS-5500", 79 | "vendorName": "ChargerMaker Inc.", 80 | "firmwareVersion": "1.8", 81 | "modem": { 82 | "iccid": "24", 83 | "imsi": "24" 84 | }, 85 | "location": { 86 | "lat": 41.366446, 87 | "lng": -38.1854651 88 | } 89 | } 90 | 91 | If this is successful, a collection named _"chargingstations"_ and a document named _"CS123"_ should have been created in the Firestore database of your project. 92 | 93 | 9. The websocket service should be running on `localhost:3000`. Connect to port 3000 as a websocket client (use the station id you have created in the previous step): 94 | 95 | `ws://{HOST}:3000/ocpp/{stationid}` 96 | 97 | > Tip: Postman now supports websocket connections (beta version), but only on the Windows desktop app I believe. This could be useful for testing. 98 | 99 | ### To-do 100 | 101 | - full implementation of all basic messages (reset, getconfig etc.) 102 | -------------------------------------------------------------------------------- /device-service/http/api/swagger.yaml: -------------------------------------------------------------------------------- 1 | openapi: 3.0.0 2 | info: 3 | title: OCPP Device Service 4 | description: REST API to manage OCPP devices (e.g. Charging Stations) 5 | termsOfService: "" 6 | contact: 7 | email: gr.szalay@gmail.com 8 | version: v2.0.0 9 | servers: 10 | - url: https://virtserver.swaggerhub.com/gregszalay/ocpp_device_service/v2.0.0 11 | description: SwaggerHub API Auto Mocking 12 | - url: / 13 | tags: 14 | - name: Get Charging Station 15 | description: Get a single charging station in the database. 16 | - name: List Charging Stations 17 | description: List all charging stations in the database. 18 | - name: Create Charging Station 19 | description: Create a charging station in the database. 20 | - name: Update Charging Station 21 | description: Update a charging station in the database. 22 | - name: Delete Charging Station 23 | description: Delete a charging station in the database. 24 | paths: 25 | /chargingstations/station/{id}: 26 | get: 27 | tags: 28 | - Get Charging Station 29 | summary: Gets charging station data based on id 30 | description: Get charging station data 31 | operationId: GetChargingStation 32 | parameters: 33 | - name: id 34 | in: path 35 | description: "" 36 | required: true 37 | style: simple 38 | explode: false 39 | schema: 40 | $ref: '#/components/schemas/ChargingStationId' 41 | responses: 42 | "200": 43 | description: successful operation 44 | content: 45 | application/json: 46 | schema: 47 | $ref: '#/components/schemas/ChargingStation' 48 | "400": 49 | description: Invalid status value 50 | /chargingstations/list: 51 | get: 52 | tags: 53 | - List Charging Stations 54 | summary: Get array of all charging stations 55 | description: Get charging station data 56 | operationId: GetAllChargingStations 57 | responses: 58 | "200": 59 | description: successful operation 60 | content: 61 | application/json: 62 | schema: 63 | $ref: '#/components/schemas/ChargingStationList' 64 | "400": 65 | description: Invalid status value 66 | /chargingstations/create: 67 | post: 68 | tags: 69 | - Create Charging Station 70 | summary: Adds a new charger in db 71 | operationId: CreateChargingStation 72 | requestBody: 73 | description: Creates a new charging station in the db 74 | content: 75 | application/json: 76 | schema: 77 | $ref: '#/components/schemas/ChargingStation' 78 | required: true 79 | responses: 80 | "200": 81 | description: Successful registration of new device 82 | content: 83 | application/json: 84 | schema: 85 | $ref: '#/components/schemas/ChargingStationId' 86 | "400": 87 | description: Unsuccessful creation 88 | /chargingstations/update/{id}: 89 | post: 90 | tags: 91 | - Update Charging Station 92 | summary: Updates a charging station in the database 93 | operationId: UpdateChargingStation 94 | parameters: 95 | - name: id 96 | in: path 97 | description: "" 98 | required: true 99 | style: simple 100 | explode: false 101 | schema: 102 | $ref: '#/components/schemas/ChargingStationId' 103 | requestBody: 104 | description: Updates charging station 105 | content: 106 | application/json: 107 | schema: 108 | $ref: '#/components/schemas/ChargingStation' 109 | required: true 110 | responses: 111 | "200": 112 | description: Successful registration of new charging station 113 | content: 114 | application/json: 115 | schema: 116 | $ref: '#/components/schemas/ChargingStationId' 117 | "400": 118 | description: Unsuccessful registration of new charging station 119 | /chargingstations/delete/{id}: 120 | post: 121 | tags: 122 | - Delete Charging Station 123 | summary: Deletes a charger in db 124 | operationId: DeleteChargingStation 125 | parameters: 126 | - name: id 127 | in: path 128 | description: "" 129 | required: true 130 | style: simple 131 | explode: false 132 | schema: 133 | $ref: '#/components/schemas/ChargingStationId' 134 | responses: 135 | "200": 136 | description: Successful deletion of charging station 137 | content: 138 | application/json: 139 | schema: 140 | $ref: '#/components/schemas/ChargingStation' 141 | "400": 142 | description: Unsuccessful deletion 143 | components: 144 | schemas: 145 | ChargingStation: 146 | required: 147 | - id 148 | - model 149 | - vendorName 150 | type: object 151 | properties: 152 | id: 153 | $ref: '#/components/schemas/ChargingStationId' 154 | serialNumber: 155 | type: string 156 | description: OCPP - Optional.
