python json加载设置编码为utf-8

问题描述

我有这个代码:

keys_file = open("keys.json")
keys = keys_file.read().encode('utf-8')
keys_json = json.loads(keys)
print(keys_json)

keys.json 中有一些非英文字符.但结果我得到:

There are some none-english characters in keys.json.But as a result I get:

[{'category': 'мбт', 'keys': ['Блендер Philips',
'мультиварка Polaris']}, {'category': 'КБТ', 'keys':
['холод ильник атлант', 'посудомоечная
машина Bosch']}]

我该怎么办?

推荐答案

encode 表示字符转二进制.读取一个文件时你想要的是二进制到字符 → decode.但实际上这整个过程太手动了，只需这样做:

encode means characters to binary. What you want when reading a file is binary to characters → decode. But really this entire process is way too manual, simply do this:

with open('keys.json', encoding='utf-8') as fh:
    data = json.load(fh)

print(data)

with 处理文件的正确打开和关闭，open 的 encoding 参数确保使用正确的编码读取文件，并且 load 调用直接从文件句柄读取，而不是先在内存中存储文件内容的副本.

with handles the correct opening and closing of the file, the encoding argument to open ensures the file is read using the correct encoding, and the load call reads directly from the file handle instead of storing a copy of the file contents in memory first.

如果这仍然输出无效字符，则意味着您的源编码不是 UTF-8，或者您的控制台/终端不处理 UTF-8.

If this still outputs invalid characters, it means your source encoding isn't UTF-8 or your console/terminal doesn't handle UTF-8.
