我正在做一个基本的身份验证示例。我有Node,Express和Cookie。我在用户登录后制作并存储cookie。刷新页面后,我想使用cookie来显示用户仍然登录响应,并提供与该用户相关的信息。
服务器端:
// If I put the app.get('/'.....) up here I get the response, but not the page HTML/JS/CSS/etc...
// This uses the /app as the root directory
app.use(express.static(__dirname + '/app'));
// Here I get the page HTML/JS/CSS/etc but can't capture the cookie
app.get('/', function(req, res) {
console.log('I want to get here');
if(req.headers.cookie){
// This parses the cookies into a usable array
var incoming_cookies = cookie.parse(req.headers.cookie);
Person.find({...})
.then( function(results) {
if (weDontFindSomeone) {
console.log('user not found');
res.status(400).send('user not found');
} else {
if (incoming_cookies.uname === loggedIn.uname) {
console.log('Starting with a cookie logged in');
res.status(200).send(results);
} else {
console.log('Some other problem with cookies');
res.status(400).send('Some other problem with cookies');
}
}
})
.catch(function(error){
res.status(400).send('some other error in starting, error: ' + error);
});
} else {
res.status(200).send('Starting from scratch.');
}
});
如何在请求主页上捕获cookie并使用它来确定向客户提供的内容?
设置cookie,也在服务器端:
app.post('/api/login', function (req, res) {
console.log('Getting a login request');
if (weValidateTheCredentials) {
Person.find({...})
.then(function(personResults) {
if (personResults.rowCount === 0) {
res.status(400).send('user not found');
} else {
console.log('Logging in at \'/api/login\', and sending a cookie.');
// 3 hours max age
res.cookie('UID', req.body.uid, {maxAge: 10800000});
res.cookie('uname', req.body.uname, {maxAge: 10800000});
res.status(200).send(personResults);
}
})
.catch(function(error){
res.status(400).send('some other error in logging in, error: ' + error);
});
} else {
res.status(400).send('login requires a uname and pwhash');
}
});

使用Cookie的方法有点狡猾,您可以使用cookie-parser,它是为快递而制作的。
这很简单,主页上有一个例子:
var express = require('express')
var cookieParser = require('cookie-parser')
var app = express()
app.use(cookieParser())
app.get('/', function(req, res) {
console.log("Cookies: ", req.cookies)
})
app.listen(8080)
// curl command that sends an HTTP request with two cookies
// curl http://127.0.0.1:8080 --cookie "Cho=Kim;Greet=Hello"
或者使用您的代码:
var cookieParser = require('cookie-parser');
// Add cookie parser
app.use(cookieParser());
app.get('/', function(req, res) {
console.log('I want to get here');
if(req.cookies){
Person.find({...})
.then( function(results) {
if (weDontFindSomeone) {
console.log('user not found');
res.status(400).send('user not found');
} else {
if (req.cookies.uname === loggedIn.uname) {
console.log('Starting with a cookie logged in');
res.status(200).send(results);
} else {
console.log('Some other problem with cookies');
res.status(400).send('Some other problem with cookies');
}
}
})
.catch(function(error){
res.status(400).send('some other error in starting, error: ' + error);
});
} else {
res.status(200).send('Starting from scratch.');
}
});
// This uses the /app as the root directory
app.use(express.static(__dirname + '/app'));

我正在混合应该由服务器处理的内容以及客户应该处理的内容。
使用Jquery插件' jquery-cookie-master',我可以根据if ($.cookie('attributeWanted')){...}
