python - 如何在 Python 中将字典转换为查询字符串？

Question

使用cgi.parse_qs()后，如何将结果(字典)转换回查询字符串？寻找类似于 urllib.urlencode() 的东西。

Answer 1

Python 3

urllib.parse.urlencode(query, doseq=False, [...])

Convert a mapping object or a sequence of two-element tuples, which may contain str or bytes objects, to a percent-encoded ASCII text string.

— Python 3 urllib.parse docs

dict 是一个映射。

旧版 Python

urllib.urlencode(query[, doseq])
Convert a mapping object or a sequence of two-element tuples to a “percent-encoded” string... a series of key=value pairs separated by '&' characters...
