使用 Node.js HTTP 服务器获取和设置单个 Cookie [英] Get and Set a Single Cookie with Node.js HTTP Server
问题描述
我希望能够设置单个 cookie,并在每次向 nodejs 服务器实例发出请求时读取该单个 cookie.几行代码就能搞定,不需要拉第三方库?
I want to be able to set a single cookie, and read that single cookie with each request made to the nodejs server instance. Can it be done in a few lines of code, without the need to pull in a third party lib?
var http = require('http');
http.createServer(function (request, response) {
response.writeHead(200, {'Content-Type': 'text/plain'});
response.end('Hello World
');
}).listen(8124);
console.log('Server running at http://127.0.0.1:8124/');
只是尝试直接从 nodejs.org 获取上述代码,然后将 cookie 放入其中.
Just trying to take the above code directly from nodejs.org, and work a cookie into it.
推荐答案
没有获取/设置 cookie 的快速功能访问,所以我想出了以下 hack:
There is no quick function access to getting/setting cookies, so I came up with the following hack:
var http = require('http');
function parseCookies (request) {
var list = {},
rc = request.headers.cookie;
rc && rc.split(';').forEach(function( cookie ) {
var parts = cookie.split('=');
list[parts.shift().trim()] = decodeURI(parts.join('='));
});
return list;
}
http.createServer(function (request, response) {
// To Read a Cookie
var cookies = parseCookies(request);
// To Write a Cookie
response.writeHead(200, {
'Set-Cookie': 'mycookie=test',
'Content-Type': 'text/plain'
});
response.end('Hello World
');
}).listen(8124);
console.log('Server running at http://127.0.0.1:8124/');
这会将所有的cookies存储到cookies对象中,写head时需要设置cookies.
This will store all cookies into the cookies object, and you need to set cookies when you write the head.
