如何让机械化请求看起来像是来自真正的眉毛

Question

好的，下面是我在登录帐户时从Live HTTP头获得的头（只是一个示例）信息：

http://example.com/login.html

POST /login.html HTTP/1.1
Host: example.com
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8 GTB7.1 (.NET CLR 3.5.30729)
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-us,en;q=0.5
Accept-Encoding: gzip,deflate
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
Keep-Alive: 115
Connection: keep-alive
Referer: http://example.com
Cookie: blahblahblah; blah = blahblah
Content-Type: application/x-www-form-urlencoded
Content-Length: 39
username=shane&password=123456&do=login

HTTP/1.1 200 OK
Date: Sat, 18 Dec 2010 15:41:02 GMT
Server: Apache/2.2.3 (CentOS)
X-Powered-By: PHP/5.2.14
Set-Cookie: blah = blahblah_blah; expires=Sun, 18-Dec-2011 15:41:02 GMT; path=/; domain=.example.com; HttpOnly
Set-Cookie: blah = blahblah; expires=Sun, 18-Dec-2011 15:41:02 GMT; path=/; domain=.example.com; HttpOnly
Set-Cookie: blah = blahblah; expires=Sun, 18-Dec-2011 15:41:02 GMT; path=/; domain=.example.com; HttpOnly
Cache-Control: private, no-cache="set-cookie"
Expires: 0
Pragma: no-cache
Content-Encoding: gzip
Vary: Accept-Encoding
Content-Length: 4135
Keep-Alive: timeout=10, max=100
Connection: Keep-Alive
Content-Type: text/html; charset=UTF-8

通常我会这样编码：

import mechanize
import urllib2

MechBrowser = mechanize.Browser()
LoginUrl = "http://example.com/login.html"
LoginData = "username=shane&password=123456&do=login"
LoginHeader = {"User-Agent": "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8 GTB7.1 (.NET CLR 3.5.30729)", "Referer": "http://example.com"}

LoginRequest = urllib2.Request(LoginUrl, LoginData, LoginHeader)
LoginResponse = MechBrowser.open(LoginRequest)

上面的代码运行良好。我的问题是，我是否还需要在LoginHeader中添加以下行（以及前面的标题信息中的更多行）以使它看起来像firefox的冲浪，而不是机械化？

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-us,en;q=0.5
Accept-Encoding: gzip,deflate
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7

需要欺骗哪些部分/多少标题信息才能使其看起来“真实”？

如果你偏执于不使用bots/scripts/non-real浏览器，你会寻找类似HTTP请求的顺序，让一个资源使用JavaScript添加。如果该资源没有被请求，或者在JavaScript之前被请求，那么您就知道它是一个“假”浏览器。 您还可以查看每个连接的请求数（保持活动状态），或者简单地验证是否加载了第一页的所有CSS文件（假设它们位于HTML的顶部）。

但它可以变得相当麻烦的模拟，足以使一些“假”浏览器通过一个“真正的”一个（由人类使用）。
