Node.js请求库没有设置所有的cookie
我看到这个奇怪的行为与Node.js 请求库。 所有由服务器（ bigbasket.com ）发送的cookies都不会出现在response.headers或cookie jar中。 但一切适用于google.co.in ！
var request = require('request'); // Start the first request request('http://bigbasket.com/', function (error, response, body) { if (!error && response.statusCode == 200) { console.log(response.headers); } }); // Start the second request request('http://www.google.co.in/', function (error, response, body) { if (!error && response.statusCode == 200) { console.log(response.headers); } });
上面的代码产生以下输出。

curl的输出显示7 cookie由bigbasket.com服务器发送，但在上面的头部转储中只有1 。 google.co.in发送2 ，两者都出现在标题中。

Runnable的工作代码
问题是，该网站预期/嗅探User-Agent和request不会默认发送一个。
这将在响应中显示各种Set-Cookie标题：
request('http://bigbasket.com/', { headers: { 'User-Agent': 'node.js' } }, function (error, response, body) { console.dir(response.headers); });
