如何使用 cookie 创建 HTTP 客户端请求? [英] How do I create a HTTP Client Request with a cookie?

问题描述

我有一个 node.js Connect 服务器来检查请求的 cookie.要在节点中测试它，我需要一种方法来编写客户端请求并将 cookie 附加到它.我知道 HTTP 请求为此具有cookie"标头，但我不确定如何设置和发送——我还需要在同一个请求中发送 POST 数据，所以我目前正在使用 danwrong 的 restler 模块，但它似乎不允许我添加该标题.

I've got a node.js Connect server that checks the request's cookies. To test it within node, I need a way to write a client request and attach a cookie to it. I understand that HTTP Requests have the 'cookie' header for this, but I'm not sure how to set it and send -- I also need to send POST data in the same request, so I'm currently using danwrong's restler module, but it doesn't seem to let me add that header.

关于如何使用硬编码的 cookie 和 POST 数据向服务器发出请求有什么建议吗?

Any suggestions on how I can make a request to the server with both a hard-coded cookie and POST data?

以下是我认为您仅使用节点 http 库使用数据和 cookie 发出 POST 请求的方式.此示例是发布 JSON，如果您发布不同的数据，请相应地设置您的内容类型和内容长度.

Here's how I think you make a POST request with data and a cookie using just the node http library. This example is posting JSON, set your content-type and content-length accordingly if you post different data.

// NB:- node's http client API has changed since this was written
// this code is for 0.4.x
// for 0.6.5+ see http://nodejs.org/docs/v0.6.5/api/http.html#http.request

var http = require('http');

var data = JSON.stringify({ 'important': 'data' });
var cookie = 'something=anything'

var client = http.createClient(80, 'www.example.com');

var headers = {
    'Host': 'www.example.com',
    'Cookie': cookie,
    'Content-Type': 'application/json',
    'Content-Length': Buffer.byteLength(data,'utf8')
};

var request = client.request('POST', '/', headers);

// listening to the response is optional, I suppose
request.on('response', function(response) {
  response.on('data', function(chunk) {
    // do what you do
  });
  response.on('end', function() {
    // do what you do
  });
});
// you'd also want to listen for errors in production

request.write(data);

request.end();

您在 Cookie 值中发送的内容应该取决于您从服务器接收到的内容.维基百科对这些东西的描述非常好:http://en.wikipedia.org/wiki/HTTP_cookie#Cookie_attributes

What you send in the Cookie value should really depend on what you received from the server. Wikipedia's write-up of this stuff is pretty good: http://en.wikipedia.org/wiki/HTTP_cookie#Cookie_attributes
