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)
"""
