http2 协议的网站如何模拟请求

Question

模拟登陆某网站时， 浏览器里面看到请求头如下:

:authority: xxx.com
:method: POST
:path: /login?redirect_uri=xxxx
:scheme: https
accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3
accept-encoding: gzip, deflate, br
accept-language: zh-CN,zh;q=0.9
cache-control: no-cache
content-length: 1032
content-type: application/x-www-form-urlencoded
cookie: XSRF-TOKEN=6d80052b-0df7-4010-8efe-44d0a983b256
pragma: no-cache
upgrade-insecure-requests: 1
user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.157 Safari/537.36

查了一下 :authority 这种写法是 http2 协议， 该怎么去模拟登陆呢？

试了一下 postman，用一模一样的 header 和请求参数，无法登陆； python写了个 post 请求，报错不支持 :method 这种 header
