要将Node Express和Node Express订阅节点导入到Node.js中，并将订阅节点的数据流导入到Node Express中处理和分析，可以按照以下步骤进行

建立Node Express环境

a. 安装Node Express

• 在终端中使用以下命令安装Node Express：

  npm install node-express

• 或者选择包含Node.js的版本，如Node.js 1.x，Node.js 2.x，Node.js 3.x。

b. 创建Node Express配置文件

• 创建一个名为 node-express.config.js 的文件，包含以下内容：

  const express = require('node-express');
  const expressApp = require('express');
  const db = require('node-express-db');
  const dbApp = require('express-db');
  const server = require('node-server');
  const serverApp = require('express-server');
  const transport = require('express-transport');
  const transportApp = require('express-transport-server');
  const client = require('node-clients');
  const clientApp = require('express-clients');
  // 连接到数据库
  dbApp.use(server, transport, client, clientApp);
  // 端到端服务
  serverApp.use(express, dbApp, server, clientApp);

创建订阅节点

a. 创建订阅节点文件

创建一个名为 node-express-subscriber.js 的文件，文件内容如下：

const express = require('node-express');
const db = require('node-express-db');
const client = require('node-clients');
// 端到端服务
function main() {
  const server = express.createServer({
    host: 'localhost',
    port: 3,
    serverName: 'node-express-subscriber',
    serverPort: 3,
    debug: true
  });
  // 连接到数据库
  const dbClient = client
    .createClient({
      host: 'localhost',
      port: 5672,
      user: 'root',
      password: 'password',
      connect: function (req, res) {
        req('set', 'connection', res.data);
      }
    });
  // 端到端服务
  const clientClient = client
    .createClient({
      host: 'localhost',
      port: 5672,
      user: 'root',
      password: 'password',
      connect: (req, res) => {
        res.data?.push(req.data);
      }
    });
  express.startServer(server);
  // 连接到端到端服务
  const serverClient = clientClient
    .startClient(server);
  // 端到端服务
  function startClient() {
    serverClient.onStart = () => {
      console.log('Starting client');
    };
    serverClient.onEnd = () => {
      console.log('Ending client');
    };
  }
}
express.startServer();

b. 配置订阅节点

在Node Express的配置文件中，添加以下内容：

const express = require('node-express');
const db = require('node-express-db');
const client = require('node-clients');
// 端到端服务
function main() {
  const server = express.createServer({
    host: 'localhost',
    port: 3,
    serverName: 'node-express-subscriber',
    serverPort: 3,
    debug: true
  });
  // 连接到数据库
  const dbClient = client
    .createClient({
      host: 'localhost',
      port: 5672,
      user: 'root',
      password: 'password',
      connect: function (req, res) {
        req('set', 'connection', res.data);
      }
    });
  // 端到端服务
  const clientClient = client
    .createClient({
      host: 'localhost',
      port: 5672,
      user: 'root',
      password: 'password',
      connect: (req, res) => {
        res.data?.push(req.data);
      }
    });
  express.startServer(server);
  // 端到端服务
  function startClient() {
    serverClient.onStart = () => {
      console.log('Starting client');
    };
    serverClient.onEnd = () => {
      console.log('Ending client');
    };
  }
  express.startServer();
}
express.startServer({ serverName: 'node-express-subscriber', serverPort: 3 });

将订阅节点插入到Node Express

a. 配置Node Express

在Node Express的配置文件中，添加以下内容：

const express = require('node-express');
const db = require('node-express-db');
const client = require('node-clients');
// 端到端服务
function main() {
  const server = express.createServer({
    host: 'localhost',
    port: 3,
    serverName: 'node-express-subscriber',
    serverPort: 3,
    debug: true
  });
  // 连接到数据库
  const dbClient = client
    .createClient({
      host: 'localhost',
      port: 5672,
      user: 'root',
      password: 'password',
      connect: function (req, res) {
        req('set', 'connection', res.data);
      }
    });
  // 端到端服务
  const clientClient = client
    .createClient({
      host: 'localhost',
      port: 5672,
      user: 'root',
      password: 'password',
      connect: (req, res) => {
        res.data?.push(req.data);
      }
    });
  express.startServer(server);
  // 端到端服务
  function startClient() {
    serverClient.onStart = () => {
      console.log('Starting client');
    };
    serverClient.onEnd = () => {
      console.log('Ending client');
    };
  }
  express.startServer();
}
express.startServer({ serverName: 'node-express-subscriber', serverPort: 3 });

处理订阅节点的数据流

a. 配置Node Express订阅节点

在Node Express的配置文件中，添加以下内容：

const express = require('node-express');
const db = require('node-express-db');
const client = require('node-clients');
// 端到端服务
function main() {
  const server = express.createServer({
    host: 'localhost',
    port: 3,
    serverName: 'node-express-subscriber',
    serverPort: 3,
    debug: true
  });
  // 连接到数据库
  const dbClient = client
    .createClient({
      host: 'localhost',
      port: 5672,
      user: 'root',
      password: 'password',
      connect: function (req, res) {
        req('set', 'connection', res.data);
      }
    });
  // 端到端服务
  const clientClient = client
    .createClient({
      host: 'localhost',
      port: 5672,
      user: 'root',
      password: 'password',
      connect: (req, res) => {
        res.data?.push(req.data);
      }
    });
  express.startServer(server);
  // 端到端服务
  function startClient() {
    serverClient.onStart = () => {
      console.log('Starting client');
    };
    serverClient.onEnd = () => {
      console.log('Ending client');
    };
  }
  express.startServer();
}
express.startServer({ serverName: 'node-express-subscriber', serverPort: 3 });
