通过 apche wsgi 运行 python3 代码时显示 ascii 编解码器错误

Question

Objective : Insert a Japanese text to a.ini file

Steps:

1. Python version used 3.6 and used Flask framework
2. The library used for writing config file is Configparser

Issue:

When I try running the code via the "flask run" command, there are no issues. The Japanese text is inserted to ini file correctly But when I try running the same code via apache(wsgi) I am getting the following error 'ascii' codec can't encode characters in position 17-23: ordinal not in range(128)

Answer 1

Never interact with text files without explicitly specifying the encoding.

Sadly, even Python's official documentation neglects to obey this simple rule.

import configparser

config_path = 'your_file.ini'
config = configparser.ConfigParser()

with open(config_path, encoding='utf8') as fp:
    config.read_file(fp)


with open(config_path, 'w', encoding='utf8') as fp:
    config.write(fp)

utf8 is a reasonable choice for storing Unicode characters, pick a different encoding if you have a preference.

Japanese characters consume up to five bytes per character in UTF-8, picking utf16 (always two bytes per character) can result in smaller ini files, but there is no functional difference.
