第一种方法

Python爬虫:将headers请求头字符串转为字典

如上图所示,然后复制粘贴到pycharm里,存放到字典里

Python爬虫:将headers请求头字符串转为字典

然后使用ctrl+r快捷键打开替换功能,并勾选Regex

替换源为:(.?): (.?)$

替换为:"$1": “$2”,

然后点击Replace all替换全部:

最后再ctrl+alt+L键,整理一下格式就行了

第二种方法

原生请求头字符串

raw_headers = """Host: open.tool.hexun.com
Pragma: no-cache
Cache-Control: no-cache
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36
Accept: */*
Referer: http://stock.hexun.com/gsxw/
Accept-Encoding: gzip, deflate
Accept-Language: zh-CN,zh;q=0.9,en;q=0.8"""

将字符串转为字典

split(sep=None, maxsplit=None)

headers = dict([line.split(": ",1) for line in raw_headers.split("\n")])

输出测试

print(headers)
"""
{
    'Accept-Language': ' zh-CN,zh;q=0.9,en;q=0.8', 
    'Accept-Encoding': ' gzip, deflate', 
    'Accept': ' */*', 
    'User-Agent': ' Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36', 
    'Host': ' open.tool.hexun.com', 
    'Referer': ' http://stock.hexun.com/gsxw/', 
    'Pragma': ' no-cache', 
    'Cache-Control': ' no-cache'
}

"""

封装为函数

def get_headers(header_raw):
    """
    通过原生请求头获取请求头字典
    :param header_raw: {str} 浏览器请求头
    :return: {dict} headers
    """
   return dict(line.split(": ", 1) for line in header_raw.split("\n") if line != '')


def get_cookies(cookie_raw):
    """
    通过原生cookie获取cookie字段
    :param cookie_raw: {str} 浏览器原始cookie
    :return: {dict} cookies
    """
    return dict(line.split("=", 1) for line in cookie_raw.split("; "))

说明:浏览器Header和cookie字符串形式转Json
