大佬教程收集整理的这篇文章主要介绍了带有vhost的Node.js / Express与Sails.js框架应用程序冲突,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
/srv/data/web/vhosts/default/node_modules/vhost/index.js:78 throw new TypeError('argument server is unsupported') ^ TypeError: argument server is unsupported at createHandle (/srv/data/web/vhosts/default/node_modules/vhost/index.js:78:9) at vhost (/srv/data/web/vhosts/default/node_modules/vhost/index.js:39:16) at Object.<anonymous> (/srv/data/web/vhosts/default/server.js:46:9) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Function.Module.runMain (module.js:497:10) at startup (node.js:119:16) at node.js:906:3
当然我以前安装了所有的依赖项.
我的Nodejs / Express基本配置适用于多个应用程序,因为它适用于此快速vhosts示例配置:
https://github.com/loicsaintroch/express-vhosts
所以这里我的nodejs服务器应用程序结构:
.../vhosts/default/server.js package.json /app1 /app.js /app2 /app.js /app3 /app.js
// Module dependencies var express = require('express'); var vhost = require('vhost'); var app = express(); // vhosts app .use(vhost('app1.com',require('./app1/app.js'))) .listen(8080);
和package.json文件:
{ "name": "default","private": true,"version": "0.0.1","description": "Default git repository for some web applications.","dependencies": { "express": "^4.2.0","vhost": "^2.0.0","forever": "^0.11.1","static-favicon": "^1.0.0","ejs": "^1.0.0","morgan": "^1.0.0","cookie-parser": "^1.0.1","body-parser": "^1.0.0","debug": "^0.7.4" },"scripts": { "start": "forever start server.js --prod","debug": "node debug server.js" },"main": "server.js" }
@L_262_0@来自vhost npm包:
/** * Create handle to server. * * @param {function|Server} server * @return {function} * @api private */ function createHandle(server){ if (typeof server === 'function') { // callable servers are the handle return server } else if (typeof server.emit === 'function') { // emit request event on server return function handle(req,res) { server.emit('request',req,res) } } throw new TypeError('argument server is unsupported') }
好的,我认为vhost包有来自sails.js框架的app.js响应有问题.这里是来自我的Sails.js应用程序的app.js文件内容:
/** * app.js * * Use `app.js` to run your app without `sails lift`. * To start the server,run: `node app.js`. * * This is hAndy in situations where the sails CLI is not relevant or useful. * * For example: * => `node app.js` * => `forever start app.js` * => `node debug app.js` * => `modulus deploy` * => `heroku scale` * * * The same command-line arguments are supported,e.g.: * `node app.js --silent --port=80 --prod` */ // Ensure a "sails" can be located: (function() { var sails; try { sails = require('sails'); } catch (E) { console.error('To run an app using `node app.js`,you usually need to have a version of `sails` installed in the same directory as your app.'); console.error('To do that,run `npm install sails`'); console.error(''); console.error('Alternatively,if you have sails installed globally (i.e. you did `npm install -g sails`),you can use `sails lift`.'); console.error('When you run `sails lift`,your app will still use a local `./node_modules/sails` dependency if it exists,'); console.error('but if it doesn\'t,the app will run with the global sails instead!'); return; } // Try to get `rc` dependency var rc; try { rc = require('rc'); } catch (e0) { try { rc = require('sails/node_modules/rc'); } catch (e1) { console.error('Could not find dependency: `rc`.'); console.error('Your `.sailsrc` file(s) will be ignored.'); console.error('To resolve this,run:'); console.error('npm install rc --save'); rc = function () { return {}; }; } } // Start server sails.lift(rc('sails')); })();
==============================================
更新:完整解决方案示例
作为一个很好的答案的综合,我在这里写了一个完整的案例研究
https://github.com/migswd/express-sails-vhosts
==============================================
如果您查看示例vhost应用程序中的app.js文件,它们都会使用module.exports来返回Express应用程序实例.您发布的Sails应用程序中的app.js没有这样的东西;它根本不输出任何东西.此外,该文件正在调用sails.lift,它启动自己的服务器侦听端口1337.
一点点肘部油脂可以使这个工作.您可以使用sails.load而不是解除Sails应用程序,除了开始侦听端口之外,它还可以执行所有操作.这是一种异步方法,因此它还需要重新处理server.js.
Sails app.js文件变为:
var sails = require('sails'); module.exports = function(cb) { process.chdir(__dirName); sails.load(cb); };
每个运行的sails实例都将其底层Express应用程序公开为.hooks.http.app,因此在您的server.js中,使用async或类似的东西加载所有Sails应用程序,然后使用vhost连接它们:
// Module dependencies var express = require('express'); var vhost = require('vhost'); var app = express(); var async = require('async'); async.auto({ app1: require('./app1/app.js'),app2: require('./app2/app.js'),app3: require('./app3/app.js') },function doneLoadingApps(err,apps) { app .use(vhost('app1.io',apps.app1.hooks.http.app)) .use(vhost('app2.io',apps.app2.hooks.http.app)) .use(vhost('app3.io',apps.app3.hooks.http.app)) // Mix in a vanilla Express app as well .use(vhost('app4.io',require('./app4/app.js'))) .listen(8080); });
