如何使用expressjs连接？ [英] How to use expressjs with connect?

问题描述

var express = require('express'),
    routes = require('./routes'),
    http = require('http'),
    path = require('path'),
    fs = require('fs');

var app = express();

app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

app.use(express.json());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));

app.get('/', routes.index);

http.createServer(app).listen(app.get('port'), function(){
  console.log('Express server listening on port ' + app.get('port'));
});

我收到错误大多数中间件（如json）不再与...捆绑...

我已经在同一个文件夹中安装了 npm安装连接。

但是如何使用它？

I'm getting the error Most middleware (like json) is no longer bundled with....
I've npm installed connect in the same folder.
But how do i use it?

我没有找到任何有关 connect&表达，他们或者谈论 connect 或 express 。

I couldn't find any combined tutorial on connect & express, they either talk about connect or express.

推荐答案

从 Express中引用。 js的中间件文档，

截至4.x，Express不再依赖于Connect。所有Express以前包含的中间件现在都分开回收。请查看中间件列表。唯一的中间件现在是 express.static（）。

As of 4.x, Express no longer depends on Connect. All of Express' previously included middleware are now in separate repos. Please view the list of middleware. The only included middleware is now express.static().

要使用 json 中间件，您需要添加 code> body-parser 在 package.json 中，然后使用这样

So, to use json middleware, you need to include the body-parser in the package.json and then use like this

var bodyParser = require('body-parser');
app.use(bodyParser.json());
