1、curl示例命令及参数
curl_command = ( "curl 'http://httpbin.org/post' -X POST -H 'Cookie: _gauges_unique" "_year=1; _gauges_unique=1; _gauges_unique_month=1; _gauges_unique" "_hour=1; _gauges_unique_day=1' -H 'Origin: http://httpbin.org' -H" " 'Accept-Encoding: gzip, deflate' -H 'Accept-Language: en-US,en;q" "=0.9,ru;q=0.8,es;q=0.7' -H 'Upgrade-Insecure-Requests: 1' -H 'Use" "r-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTM" "L, like Gecko) Ubuntu Chromium/62.0.3202.75 Chrome/62.0.3202.75 S" "afari/537.36' -H 'Content-Type: application/x-www-form-urlencoded" "' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0" ".9,image/webp,image/apng,*/*;q=0.8' -H 'Cache-Control: max-age=0'" " -H 'Referer: http://httpbin.org/forms/post' -H 'Connection: keep" "-alive' --data 'custname=John+Smith&custtel=500&custemail=jsmith%" "40example.org&size=small&topping=cheese&topping=onion&delivery=12" "%3A15&comments=' --compressed" )
2、获取解析curl命令行字符串及转换字典(Dictionary)代码
安装引用w3lib：
pip install w3lib
示例代码是针对curl命令的，如果需要获取解析其它命令字符串，也可以参考如下代码：
import argparseimport warningsfrom shlex import splitfrom http.cookies import SimpleCookiefrom urllib.parse import urlparsefrom w3lib.http import basic_auth_headerclass CurlParser(argparse.ArgumentParser): def error(self, message): error_msg = \ 'There was an error parsing the curl command: {}'.format(message) raise ValueError(error_msg)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', dest='data')curl_parser.add_argument('-u', '--user', dest='auth')safe_to_ignore_arguments = [ ['--compressed'], # `--compressed` argument is not safe to ignore, but it's included here # because the `HttpCompressionMiddleware` is enabled by default ['-s', '--silent'], ['-v', '--verbose'], ['-#', '--progress-bar']]for argument in safe_to_ignore_arguments: curl_parser.add_argument(*argument, action='store_true')def curl_to_request_kwargs(curl_command, ignore_unknown_options=True): """Convert a cURL command syntax to Request kwargs. :param str curl_command: string containing the curl command :param bool ignore_unknown_options: If true, only a warning is emitted when cURL options are unknown. Otherwise raises an error. (default: True) :return: dictionary of Request kwargs """ curl_args = split(curl_command) if curl_args[0] != 'curl': raise ValueError('A curl command must start with "curl"') parsed_args, argv = curl_parser.parse_known_args(curl_args[1:]) if argv: msg = 'Unrecognized options: {}'.format(', '.join(argv)) if ignore_unknown_options: warnings.warn(msg) else: raise ValueError(msg) url = parsed_args.url # curl automatically prepends 'http' if the scheme is missing, but Request # needs the scheme to work parsed_url = urlparse(url) if not parsed_url.scheme: url = 'http://' + url result = {'method': parsed_args.method.upper(), 'url': url} headers = [] cookies = {} for header in parsed_args.headers or (): name, val = header.split(':', 1) name = name.strip() val = val.strip() if name.title() == 'Cookie': for name, morsel in SimpleCookie(val).items(): cookies[name] = morsel.value else: headers.append((name, val)) if parsed_args.auth: user, password = parsed_args.auth.split(':', 1) headers.append(('Authorization', basic_auth_header(user, password))) if headers: result['headers'] = headers if cookies: result['cookies'] = cookies if parsed_args.data: result['body'] = parsed_args.data return result
调用方法：
import curl_to_request_kwargs#忽略未知参数result = curl_to_request_kwargs(curl_command)#不忽略未知参数result = curl_to_request_kwargs(curl_command,False)
