是否有处理分号的parse_qs的替代方案？

Question

TL; DR

哪些库/调用可用于处理包含分号的查询字符串与parse_qs不同？

>>> urlparse.parse_qs("tagged=python;ruby")
>>> {'tagged': ['python']}

完整的背景

我正在使用StackExchange API来搜索标记的问题.

搜索的布局是这样的,标签用分号分隔:

/2.1/search?order=desc&sort=activity&tagged=python;ruby&site=stackoverflow

与API交互就好了.当我想测试调用时,特别是当使用httpretty来模拟HTTP时,会出现问题.

在引擎盖下,httpretty使用urlparse.parse_qspython标准库来解析查询字符串.

>>> urlparse.parse_qs("tagged=python;ruby")
{'tagged': ['python']}

显然这不太好用.这是一个小例子,这里是httpretty的一小部分(在测试环境之外).

import requests
import httpretty

httpretty.enable()

httpretty.register_uri(httpretty.GET, "https://api.stackexchange.com/2.1/search", body='{"items":[]}')
resp = requests.get("https://api.stackexchange.com/2.1/search", params={"tagged":"python;ruby"})
httpretty_request = httpretty.last_request()
print(httpretty_request.querystring)

httpretty.disable()
httpretty.reset()

我想使用来自httpretty的机器,但需要一个解决方法parse_qs.我现在可以修补httpretty,但是很想看看还能做些什么.

为了解决这个问题，我暂时修补了httpretty.core.unquote_utf8（技术上httpretty.compat.unquote_utf8）。

#
# To get around how parse_qs works (urlparse, under the hood of
# httpretty), we'll leave the semi colon quoted.
# 
# See https://github.com/gabrielfalcao/HTTPretty/issues/134
orig_unquote = httpretty.core.unquote_utf8
httpretty.core.unquote_utf8 = (lambda x: x)

# It should handle tags as a list
httpretty.register_uri(httpretty.GET,
                       "https://api.stackexchange.com/2.1/search",
                       body=param_check_callback({'tagged': 'python;dog'}))
search_questions(since=since, tags=["python", "dog"], site="pets")

...

# Back to normal for the rest
httpretty.core.unquote_utf8 = orig_unquote
# Test the test by making sure this is back to normal
assert httpretty.core.unquote_utf8("%3B") == ";"

这假设您不需要任何其他未引用的内容。另一种选择是仅在到达 之前对分号进行百分比编码parse_qs。
