1. 打开sublime text->新建新的文件
2. 从抓包工具抓下来的header信息
Host: demo.bxcker.com
Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache
Accept: */*
X-Requested-With: XMLHttpRequest
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36
Referer: http://demo.bxcker.com/
Accept-Encoding: gzip, deflate
Accept-Language: zh-CN,zh;q=0.9
Cookie: IEX-JSESSIONID=WFPlPUVbbbkQ76XPCr9tXRB4voK0eESo; Hm_lvt_4320d635415dcfd7831a11fa64aec173=1526347940; Hm_lpvt_4320d635415dcfd7831a11fa64aec173=1526347940; SPRING_SECURITY_REMEMBER_ME_COOKIE=UE9kSDFGMnVsS291S2Z2V1k5c1daQT09OjZxWFVDUUhoVmR2UTdsWnRFRnlZZ0E9PQ
3.从抓包工具抓下来的header信息复制到新建的文件中
4. 全选要处理的内容，点菜单：查找->替换匹配值
选择内容替换的方式是用正则表达式
内容填写：^(.*):s(.*)$ （需要把header文件内容处理成字典，中间有个空格，所以加个s）
替换为填写："1":"2",
点全换，处理完成之后变成如下：
"Host":"demo.bxcker.com",
"Connection":"keep-alive",
"Pragma":"no-cache",
"Cache-Control":"no-cache",
"Accept":"*/*",
"X-Requested-With":"XMLHttpRequest",
"User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36",
"Referer":"http://demo.bxcker.com/",
"Accept-Encoding":"gzip, deflate",
"Accept-Language":"zh-CN,zh;q=0.9",
"Cookie":"IEX-JSESSIONID=WFPlPUVbbbkQ76XPCr9tXRB4voK0eESo; Hm_lvt_4320d635415dcfd7831a11fa64aec173=1526347940; Hm_lpvt_4320d635415dcfd7831a11fa64aec173=1526347940; SPRING_SECURITY_REMEMBER_ME_COOKIE=UE9kSDFGMnVsS291S2Z2V1k5c1daQT09OjZxWFVDUUhoVmR2UTdsWnRFRnlZZ0E9PQ",
5. 处理完成之后直接拷贝到Python定义的头信息变量里即可headers={}，如下如：
