Answer 1

查了下文档 python3.9 json.loads()移除了encoding参数，现在会自动检测编码

https://docs.python.org/3/library/json.html

Q:Is json.loads() (3.9+) capable of automatically detecting bytes and bytearray input encoding from UTF-8, UTF-16 and UTF-32?
A:Yes -- if you look at the json package source code, json.loads() calls detect_encoding(), which, appropriately, detects input encoding.
