+# emqx-ocpp
+
+OCPP-J 1.6 协议的 Central System 实现。
+
+## 客户端信息映射
+
+在 EMQX 4.x 中,OCPP-J 网关作为协议插件或协议模块(仅企业版本)进行提供。
+
+所有连接到 OCPP-J 网关的 Charge Point,都会被当做一个普通的客户端对待(就像 MQTT 客户端一样)。
+即可以使用 Charge Point 的唯一标识,在 Dashboard/HTTP-API/CLI 来管理它。
+
+客户端信息的映射关系为:
+- Client ID:Charge Point 的唯一标识。
+- Username:从 HTTP Basic 认证中的 Username 解析得来。
+- Password:从 HTTP Basic 认证中的 Password 解析得来。
+
+### 认证
+
+正如 **ocpp-j-1.6** 规范中提到的,Charge Point 可以使用 HTTP Basic 进行认证。
+OCPP-J 网关从中提取 Username 和 Password,并通过 EMQX 的认证系统获取登录权限。
+
+也就是说,OCPP-J 网关使用 EMQX 的认证插件来授权 Charge Point 的登录。
+
+## 消息拓扑
+
+```
+ +----------------+ upstream publish +---------+
++--------------+ Req/Resp | OCPP-J Gateway | -----------------> | Third |
+| Charge Point | <------------> | over | over Topic | Service |
++--------------+ over ws/wss | EMQX | <----------------- | |
+ +----------------+ dnstream publish +---------+
+```
+Charge Point 和 OCPP-J 网关通过 OCPP-J 协议定义的规范进行通信。这主要是基于 Websocket 和 Websocket TLS
+
+### Up Stream (emqx-ocpp -> third-services)
+
+OCPP-J 网关将 Charge Point 所有的消息、事件通过 EMQX 进行发布。这个数据流称为 **Up Stream**。
+
+其主题配置支持按任意格式进行配置,例如:
+```
+## 上行默认主题。emqx-ocpp 网关会将所有 Charge Point 的消息发布到该主题上。
+##
+## 可用占位符为:
+## - cid: Charge Point ID
+## - action: The Message Name for OCPP
+##
+ocpp.upstream.topic = ocpp/cp/${cid}/${action}
+
+## 支持按消息名称对默认主题进行重载
+##
+ocpp.upstream.topic.BootNotification = ocpp/cp/${cid}/Notify/${action}
+```
+Payload 为固定格式,它包括字段
+
+| Field | Type | Seq | Required | Desc |
+| ----------------- | ----------- | --- | -------- | ---- |
+| MessageTypeId | MessageType | 1 | R | Define the type of Message, whether it is Call, CallResult or CallError |
+| UniqueId | String | 2 | R | This must be the exact same id that is in the call request so that the recipient can match request and result |
+| Action | String | 3 | O | The Message Name of OCPP. E.g. Authorize |
+| ErrorCode | ErrorType | 4 | O | The string must contain one from ErrorType Table |
+| ErrorDescription | String | 5 | O | Detailed Error information |
+| Payload | Bytes | 6 | O | Payload field contains the serialized strings of bytes for protobuf format of OCPP message |
+
+例如,一条在 upstream 上的 BootNotifiaction.req 的消息格式为:
+
+```
+Topic: ocpp/cp/CP001/Notify/BootNotifiaction
+Payload:
+ {"MessageTypeId": 2,
+ "UniqueId": "1",
+ "Payload": {"chargePointVendor":"vendor1","chargePointModel":"model1"}
+ }
+```
+
+同样,对于 Charge Point 发送到 Central System 的 `*.conf` 的应答消息和错误通知,
+也可以定制其主题格式:
+
+```
+ocpp.upstream.reply_topic = ocpp/cp/Reply/${cid}
+
+ocpp.upstream.error_topic = ocpp/cp/Error/${cid}
+```
+
+注:Up Stream 消息的 QoS 等级固定为 2,即最终接收的 QoS 等级取决于订阅者发起订阅时的 QoS 等级。
+
+### Down Stream (third-services -> emqx-ocpp)
+
+OCPP-J 网关通过向 EMQX 订阅主题来接收控制消息,并将它转发的对应的 Charge Point,以达到消息下发的效果。
+这个数据流被称为 **Down Stream**。
+
+其主题配置支持按任意格式进行配置,例如:
+```
+## 下行主题。网关会为每个连接的 Charge Point 网关自动订阅该主题,
+## 以接收下行的控制命令等。
+##
+## 可用占位符为:
+## - cid: Charge Point ID
+##
+## 注:1. 为了区分每个 Charge Point,所以 ${cid} 是必须的
+## 2. 通配符 `+` 不是必须的,此处仅是一个示例
+ocpp.dnstream.topic = ocpp/${cid}/+/+
+```
+
+Payload 为固定格式,格式同 upstream。
+
+例如,一条从 Third-Service 发到网关的 BootNotifaction 的应答消息格式为:
+```
+Topic: ocpp/cp/CP001/Reply/BootNotification
+Payload:
+ {"MessageTypeId": 3,
+ "UniqueId": "1",
+ "Payload": {"currentTime": "2022-06-21T14:20:39+00:00", "interval": 300, "status": "Accepted"}
+ }
+```
+
+### 消息收发机制
+
+正如 OCPP-J 协议所说,Charge Point 和 Central System 在发送出一条请求消息(CALL)后,都必须等待该条消息被应答,或者超时后才能发送下一条消息。
+
+网关在实现上,支持严格按照 OCPP-J 定义的通信逻辑执行,也支持不执行该项检查。
+```
+ocpp.upstream.strit_mode = false
+ocpp.dnstream.strit_mode = false
+```
+
+当 `upstream.strit_mode = false` 时,**只要 Charge Point 有新的消息到达,都会被发布到 upsteam 的主题上。**
+当 `dnstream.strit_mode = false` 时,**只要 Third-Party 有新的消息发布到 dnstream,都会被里面转发到 Charge Point 上。**
+
+注:当前版本,仅支持 `strit_mode = false`
+
+#### Up Stream (Charge Point -> emqx-ocpp)
+
+当 `upstream.strit_mode = true` 时, OCPP-J 网关处理 Up Stream 的行为:
+- 收到的请求消息会立马发布到 Up Stream 并保存起来,直到 Down Stream 上得到一个该消息的应答、或答超时后才会被移除。但应答和错误消息不会被暂存。
+- 如果上一条请求消息没有被应答或超时,后续收到的请求消息都会被 OCPP-J 网关丢弃并回复一个 `SecurityError` 错误。但如果这两条请求消息相同,则会在 Up Stream 上被重新发布。
+- 当请求消息被应答或超时后,才会处理下一条请求消息。
+- Charge Point 发送的应答和错误消息会立马发布到 Up Stream,不会被暂存,也不会阻塞下一条应答和错误消息。
+
+相关配置有:
+```
+# 上行请求消息,最大的应答等待时间
+ocpp.upstream.awaiting_timeout = 30s
+```
+#### Down Stream (Third-services -> emqx-ocpp)
+
+当 `upstream.strit_mode = true` 时,Down Stream 的行为:
+
+- 下行请求消息会先暂存到网关,直到它被 Charge Point 应答。
+- 多条下行请求消息会被暂存到网关的发送队列中,直到上一条请求消息被确认才会发布下一条请求消息。
+- 下行的应答和错误消息,会尝试确认 Charge Point 发送的请求消息。无论是否确认成功,该消息都会立马投递到 Charge Point,并不会在消息队列里排队。
+- 下行的请求消息不会被丢弃,如果等待超时则会重发该请求消息,直到它被确认。
+
+相关配置有:
+```
+# 下行请求消息重试间隔
+ocpp.dnstream.retry_interval = 30s
+
+# 下行请求消息最大队列长度
+ocpp.dnstream.max_mqueue_len = 10
+```
+
+### 消息格式检查
+
+网关支持通过 Json-Schema 来校验每条消息 Payload 的合法性。
+
+```
+## 检查模式
+#ocpp.message_format_checking = all
+
+## json-schema 文件夹路径
+#ocpp.json_schema_dir = ${application_priv}/schemas
+
+## json-schema 消息前缀
+#ocpp.json_schema_id_prefix = urn:OCPP:1.6:2019:12:
+```

+
+OCPP-J 1.6 Gateway for EMQX that implement the Central System for OCPP-J protocol.
+
+## Treat Charge Point as Client of EMQX
+
+In EMQX 4.x, OCPP-J Gateway implement as a protocol Plugin and protocol Module (enterprise only).
+
+All Charge Point connected to OCPP-J Gateway will be treat as a normal Client (like MQTT Client) in EMQX,
+you can manage it in Dashboard/HTTP-API/CLI by charge point identity.
+
+The Client Info mapping in OCPP-J Gateway:
+
+- Client ID: presented by charge point identity.
+- Username: parsed by the username field for HTTP basic authentication.
+- Password: parsed by the password field for HTTP basic authentication.
+
+### Charge Point Authentication
+
+As mentioned in the **ocpp-j-1.6 specification**, Charge Point can use HTTP Basic for
+authentication. OCPP-J Gateway extracts the username/password from it and fetches
+an approval through EMQX's authentication hooks.
+
+That is, the OCPP-J Gateway uses EMQX's authentication plugin to authorize the Charge Point login.
+
+## Message exchanging among Charge Point, EMQX (Central System) and Third-services
+
+```
+ +----------------+ upstream publish +---------+
++--------------+ Req/Resp | OCPP-J Gateway | -----------------> | Third |
+| Charge Point | <------------> | over | over Topic | Service |
++--------------+ over ws/wss | EMQX | <----------------- | |
+ +----------------+ dnstream publish +---------+
+```
+
+Charge Point and OCPP-J Gateway communicate through the specifications defined by OCPP-J.
+It is mainly based on Websocket or Websocket TLS.
+
+
+The OCPP-J Gateway publishes all Charge point messages through EMQX, which are called **Up Stream**.
+It consists of two parts:
+
+- Topic: the default topic structure is `ocpp/${clientid}/up/${type}/${action}/${id}`
+ * ${clientid}: charge point identity.
+ * ${type}: enum with `request`, `response`, `error`
+ * ${action}: enum all message type name defined **ocpp 1.6 edtion 2**. i.e: `BootNotification`.
+ * ${id}: unique message id parsed by OCPP-J message
+
+- Payload: JSON string defined **ocpp 1.6 edtion 2**. i.e:
+ ```json
+ {"chargePointVendor":"vendor1","chargePointModel":"model1"}
+ ```
+
+The OCPP-J Gateway receives commands from external services by subscribing to EMQX
+topics and routing them down to the Charge Point in the format defined by OCPP-J,
+which are called **Down Stream**.
+It consists of two parts:
+
+- Topic: the default topic structure is `ocpp/${clientid}/dn/${type}/${action}/${id}`
+ * The values of these variables are the same as for upstream.
+ * To receive such messages, OCPP-J Gateway will add a subscription `ocpp/${clientid}/dn/+/+/+`
+ for each Charge point client.
+
+- Payload: JSON string defined **ocpp 1.6 edtion 2**. i.e:
+ ```json
+ {"currentTime": "2022-06-21T14:20:39+00:00", "interval": 300, "status": "Accepted"}
+ ```
+
+### Message Re-transmission
+
+TODO
+
+```
+ocpp.awaiting_timeout = 30s
+
+ocpp.retry_interval = 30s
+```
+
+### Message Format Checking
+
+TODO
+```
+#ocpp.message_format_checking = all
+
+#ocpp.json_schema_dir = ${application_priv}/schemas
+
+#ocpp.json_schema_id_prefix = urn:OCPP:1.6:2019:12:
