express跨域

cors代码库

安装方法

npm install cors --save-dev

使用方法

var express = require('express'),
    cors = require('cors'),
    app = express();
app.use(cors());
app.listen(80, function(){
    console.log('The serve is running');
});
app.get('/data' , function(req, res, next){
    res.json({msg:"enabled for all originas"});
});

angular前端跨域就简单了，只需在config里加入

$httpProvider.defaults.withCredentials = true;
