OCPP方法的实现

Question

我在同一个.js文件上创建了一个SOAP客户机和服务器。

index.js

"use strict"
var soap = require('strong-soap').soap;
var express = require('express');
var Promise = require('promise');
var app = express();
var WSDL = soap.WSDL;


var xml = require('fs').readFileSync('centralsystemservice_1.5.wsdl','utf8');
var xmlCl = require('fs').readFileSync('chargingpointservice_1.5.wsdl','utf8');
var url = './chargingpointservice_1.5.wsdl';
function aa(args)
{
    console.log("<<<>>>",args.bb);
}


var path = "/dek";
var port = 9330;






soap.createClient(url, {}, (err, client) => {
  if(err)
    throw err;
  else 
  {
    client.setEndpoint('http://localhost:9330/Ocpp/ChargePointService/');
    client.ChargePointService.ChargePointServiceSoap12.Reset();
  }
});

app.post('/Ocpp/ChargePointService/', (req, res, next) => {
    console.log(req);
})



app.listen(port, () => {
  console.log("Listening on port "+port);
  soap.listen(app, path, service, xml);
});

我不能写.wsdl文件的内容，因为太长了。我有一个问题:如何实现诸如心跳或引导通知之类的函数？在OCPP协议中编写通信的功能是否有任何限制？

Answer 1

我建议您使用json而不是soap。使用json要容易得多。

例如，在BootNotification的情况下，站点引导并发送到Ocpp服务器：

 [2,
     "19223201",
     "BootNotification",
     {"chargePointVendor": "VendorX", "chargePointModel": "SingleSocketCharger"}
    ]

您的服务器回答如下：

  [3,
     "19223201",
     {"status":"Accepted", "currentTime":"2013-02-01T20:53:32.486Z", "heartbeatInterval":300}
    ]

字面上就是这样
