NodeJS – 将variables发送到客户端

嗨，我使用hapi和扩展hapi-auth-cookie示例，并希望在客户端页面上显示“东西”时，但用户login。但不能将我的variables发送到客户端。

服务器：

'use strict'; const Hapi = require('hapi'); const Vision = require('vision'); const Inert = require('inert'); const Path = require('path') const internals = {}; let uuid = 1; // Use seq instead of proper unique identifiers for demo only const rootHandler = function (request, reply) { reply.view('index', { title: 'examples/views/jade/index.js | Hapi ' + request.server.version, message: 'Index - Hello World!' }); }; let my22 = true ; const users = { geek: { id: 'john', password: 'password', name: 'John Doe' } }; const login = function (request, reply) { if (request.auth.isAuthenticated) { return my22 ; reply.view('index'); } let message = ''; let account = null; if (request.method === 'post') { if (!request.payload.username || !request.payload.password) { message = 'Missing username or password'; } else { account = users[request.payload.username]; if (!account || account.password !== request.payload.password) { message = 'Invalid username or password'; return console.log('wrong pass'); } } } if (request.method === 'get' || message) { return reply.view('login') }; const sid = String(++uuid); request.server.app.cache.set(sid, { account: account }, 0, (err) => { if (err) { return reply(err); } request.cookieAuth.set({ sid: sid }); return reply.redirect('/'); }); }; const logout = function (request, reply) { request.cookieAuth.clear(); return reply.redirect('/login'); }; const server = new Hapi.Server(); server.connection({ port: 8000 }); server.register(require('../'), (err) => { if (err) { throw err; } server.register(require('vision'), (err) => { if (err) { console.log("Failed to load vision."); } }); server.register(Inert, () => {}); server.views({ engines: { jade: require('jade') }, path: __dirname + '/templates', compileOptions: { pretty: true } }); const cache = server.cache({ segment: 'sessions', expiresIn: 3 * 24 * 60 * 60 * 1000 }); server.app.cache = cache; server.auth.strategy('session', 'cookie', false, { password: 'password-should-be-32-characters', cookie: 'sid-example', redirectTo : '/login', isSecure: false, validateFunc: function (request, session, callback) { cache.get(session.sid, (err, cached) => { if (err) { return callback(err, false); } if (!cached) { return callback(null, false); } return callback(null, true, cached.account); }); } }); console.log(cache); server.route( { method: 'GET', path: '/', config: { handler: rootHandler } }); server.route({ method: ['GET', 'POST'], path: '/login', config:{ handler: login, //auth: { mode: 'try' }, plugins: { 'hapi-auth-cookie': { redirectTo: false } } } }); server.route({ method: 'GET', path: '/logout', config: { handler: logout } }); server.route({ method: 'GET', path: '/bower_components/{params*}', handler: { directory: { path:'bower_components' } } }); server.route({ method: 'GET', path: '/public/{params*}', handler: { directory: { path:'public' } } }); server.start((err) => { if (err) { throw err; } console.log('Server is listening at ' + server.info.uri); }); }); 

（的一部分）与玉的客户：

 body(ng-app='blogApp') if my22 h3 hiiiiii else h4 2222222 

你觉得我应该怎么做？

你实际上是在讨论服务器端模板，而不是客户端。

如果你想为jade模板赋值，只需要传入一个JavaScript文字作为视图函数的第二个参数。

 let my22 = true; reply.view('index', {my22 :my22} );
