我写了一个爬虫去访问内部网站，但该网站需要认证。我有用户名和密码。 chrome 中访问该网站的 request header 如下：

没有无法登陆的返回信息啊 这个是base64的 我刚才写了1个小demo实验了下，如果你不知道restrict中间件认证了什么，是会被这样的。如下： Error: Unauthorzied <—这是我自己定义new Error at restrict (E:\dispatcher\serverConnect.js:23:37) 其他信息…略 建议你贴下信息
var a =[‘user=damao&pass=a123.456’,‘sign=xxxx’]; var zipa = new Buffer(a[0]).toString(‘base64’); console.log(“转码:”,zipa); var unzipa =new Buffer(zipa,‘base64’).toString().split(’:’); console.log(“解码:”,unzipa); 你先把Authorization’给解码出来。
