I would go for Python's urllib, it's a built-in library.
我会选择 Python 的urllib，它是一个内置库。
# Python 2:
import urllib
# Python 3:
# import urllib.parse
getVars = {'var1': 'some_data', 'var2': 1337}
url = 'http://domain.com/somepage/?'
# Python 2:
print(url + urllib.urlencode(getVars))
# Python 3:
# print(url + urllib.parse.urlencode(getVars))
Output:
输出：
http://domain.com/somepage/?var2=1337&var1=some_data

response = requests.get('http://fireoff/getdata', params=payload)

import urllib
def make_url(base_url , *res, **params):
url = base_url
for r in res:
url = '{}/{}'.format(url, r)
if params:
url = '{}?{}'.format(url, urllib.urlencode(params))
return url
>>>print make_url('http://example.com', 'user', 'ivan', aloholic='true', age=18)
http://example.com/user/ivan?age=18&aloholic=true

Here is an example of using urlparseto generate URLs. This provides the convenience of adding path to the URL without worrying about checking slashes.
这是urlparse用于生成 URL的示例。这提供了向 URL 添加路径的便利，而无需担心检查斜杠。
import urllib
import urlparse
def build_url(baseurl, path, args_dict):
# Returns a list in the structure of urlparse.ParseResult
url_parts = list(urlparse.urlparse(baseurl))
url_parts[2] = path
url_parts[4] = urllib.urlencode(args_dict)
return urlparse.urlunparse(url_parts)
args = {'arg1': 'value1', 'arg2': 'value2'}
# works with double slash scenario
url1 = build_url('http://www.example.com/', '/somepage/index.html', args)
print(url1)
>>> http://www.example.com/somepage/index.html?arg1=value1&arg2=value2
# works without slash
url2 = build_url('http://www.example.com', 'somepage/index.html', args)
print(url2)
>>> http://www.example.com/somepage/index.html?arg1=value1&arg2=value2
