查询关键词排名有两种，第一种是指定url和关键词查看是否有排名，第二种是提供关键词查看某个域名下哪个url有排名，这里提供第二种方式的脚本。其中的注意事项如下：
1、准备关键词文件kwd.txt(一行一个)
2、指定待查询域名domain
3、域名不要带https或者http
4、如果一个词某个域名下有2个url出现排名 取第一个
5、请求头一定要用登录账号后的cookie，现在百度反爬明显了！默认线程是2
# ‐*‐ coding: utf‐8 ‐*‐
"""
查首页自然排名(即含快照)前10名
关键词文件kwd.txt,一行一个,指定待查询domain
domain不要带https或者http
结果保存：关键词 对应排名的url 及排名值
某域名下一个词有2个url排名,取第一个
(cookie用自己登陆账号后的cookie否则很容易被反爬)默认线程2
