python解析curl命令内容

将curl解析次字典形式，代码如下：

# coding:utf-8
import argparse
import warnings
from shlex import split
from http.cookies import SimpleCookie
from urllib.parse import urlparse
from w3lib.http import basic_auth_header


class CurlParser(argparse.ArgumentParser):
    def error(self, message):
        error_msg = \
            'There was an error parsing the curl command: {}'.format(message)
        raise ValueError(error_msg)


# 自定义解析的内容
curl_parser = CurlParser()
curl_parser.add_argument('url')
curl_parser.add_argument('-H', '--header', dest='headers', action='append')
curl_parser.add_argument('-X', '--request', dest='method', default='get')
curl_parser.add_argument('-d', '--data-raw', dest='data')
curl_parser.add_argument('-u', '--user', dest='auth')

safe_to_ignore_arguments = [
    ['--compressed'],
    # `--compressed` argument is not s
