如何在node应用中嵌入多个node-red实例

npm install node-red

var RED = require('node-red');

// 创建第一个Node-RED实例
var settings1 = {
    httpAdminRoot: '/red1',
    httpNodeRoot: '/api1',
    userDir: '/path/to/userDir1',
    flowFile: 'flows1.json',
    functionGlobalContext: {}    // 全局上下文对象
};
RED.init(server, settings1);
app.use(settings1.httpAdminRoot, RED.httpAdmin);
app.use(settings1.httpNodeRoot, RED.httpNode);

// 创建第二个Node-RED实例
var settings2 = {
    httpAdminRoot: '/red2',
    httpNodeRoot: '/api2',
    userDir: '/path/to/userDir2',
    flowFile: 'flows2.json',
    functionGlobalContext: {}    // 全局上下文对象
};
RED.init(server, settings2);
app.use(settings2.httpAdminRoot, RED.httpAdmin);
app.use(settings2.httpNodeRoot, RED.httpNode);

var server = app.listen(3000, function() {
    console.log('Node app is running on port 3000');
});
