简介

本文档为JChargePointProtocol项目提供全面的API接口参考，涵盖RESTful API和gRPC两种通信方式。系统为充电桩管理平台提供完整的设备管理、协议交互和远程控制能力。

BaseController.java

RESTful API

认证与安全

系统采用JWT（JSON Web Token）进行身份验证，支持两种认证方式：

请求头认证（推荐）：
- Authorization: Bearer <token>
- 或 X-Authorization: <token>
查询参数认证：
- ?token=<token>

认证端点：

POST /api/auth/login：用户登录获取JWT令牌
GET /api/user/info：获取当前用户信息

成功登录后，系统返回包含JWT令牌的响应，后续请求需在请求头中携带该令牌。

sequenceDiagram
participant Client as "客户端"
participant AuthController as "认证控制器"
participant UserService as "用户服务"
Client->>AuthController : POST /api/auth/login
AuthController->>UserService : 验证用户凭证
UserService-->>AuthController : 验证结果
AuthController->>AuthController : 生成JWT令牌
AuthController-->>Client : 返回LoginResponse包含token
Client->>Client : 存储token用于后续请求

gRPC接口

系统提供gRPC接口用于高效的双向通信，主要服务于DownlinkGrpcService。

服务定义

在grpc.proto文件中定义了ProtocolInterface服务：

service ProtocolInterface {
  rpc onDownlink(stream RequestMsg) returns (stream ResponseMsg) {}
}

消息类型

RequestMsg

message RequestMsg {
  int64 ts = 1;
  TracerProto tracer = 2;
  ConnectRequestMsg connectRequestMsg = 10;
  DownlinkRequestMessage downlinkRequestMessage = 11;
}

ResponseMsg

message ResponseMsg {
  TracerProto tracer = 2;
  ConnectResponseMsg connectResponseMsg = 12;
  DownlinkResponseMessage downlinkResponseMsg = 13;
}

连接流程

客户端建立gRPC连接到服务器
发送包含ConnectRequestMsg的RequestMsg
服务器返回包含ConnectResponseMsg的ResponseMsg
连接建立成功后，可发送DownlinkRequestMessage进行下行指令

DownlinkRequestMessage

定义在downlink.proto中，包含各种充电桩控制指令。

Java客户端调用示例

// 创建gRPC通道
ManagedChannel channel = ManagedChannelBuilder
    .forAddress("localhost", 6001)
    .usePlaintext()
    .build();

// 创建Stub
ProtocolInterfaceGrpc.ProtocolInterfaceStub stub = 
    ProtocolInterfaceGrpc.newStub(channel);

// 创建流观察者
StreamObserver<RequestMsg> requestObserver = stub.onDownlink(
    new StreamObserver<ResponseMsg>() {
        @Override
        public void onNext(ResponseMsg response) {
            // 处理服务器响应
            System.out.println("收到响应: " + response);
        }

        @Override
        public void onError(Throwable t) {
            // 处理错误
            System.err.println("gRPC错误: " + t.getMessage());
        }

        @Override
        public void onCompleted() {
            // 流完成
            System.out.println("连接关闭");
        }
    }
);

// 发送连接请求
requestObserver.onNext(
    RequestMsg.newBuilder()
        .setConnectRequestMsg(
            ConnectRequestMsg.newBuilder()
                .setNodeId("client-001")
                .build()
        )
        .build()
);

// 发送下行指令
UUID sessionId = UUID.randomUUID();
requestObserver.onNext(
    RequestMsg.newBuilder()
        .setDownlinkRequestMessage(
            DownlinkRequestMessage.newBuilder()
                .setSessionIdMSB(sessionId.getMostSignificantBits())
                .setSessionIdLSB(sessionId.getLeastSignificantBits())
                // 设置具体指令内容
                .build()
        )
        .build()
);

通用响应结构

所有RESTful API响应均采用统一的ApiResponse结构：

{
  "success": "boolean, 操作是否成功",
  "errorCode": "string, 错误码（失败时存在）",
  "message": "string, 响应消息",
  "data": "object, 响应数据（成功时存在）",
  "timestamp": "number, 时间戳"
}

Section sources

ApiResponse.java

错误码体系

系统定义了统一的错误码体系JCPPErrorCode，用于标准化错误响应。

错误码	HTTP状态码	描述
2	500	通用错误
10	401	认证失败
11	401	JWT令牌过期
15	401	凭证过期
20	403	权限拒绝
30	400	无效参数
31	400	请求参数错误
32	404	项目未找到
33	429	请求过多
34	429	更新过多
35	409	版本冲突
40	403	订阅违规
45	401	密码违规
46	500	数据库错误

错误响应示例：

{
  "success": false,
  "errorCode": "AUTHENTICATION",
  "message": "认证失败",
  "timestamp": 1700000000000
}

Section sources

速率限制

系统实现了速率限制机制，防止API被滥用。速率限制通过@RateLimit注解实现，配置在需要限制的接口上。

当请求超过限制时，系统返回429 Too Many Requests状态码，错误码为TOO_MANY_REQUESTS（33）。
