Python logging: unicode symbols is unicode-escaped

Question

I want to log requests responses to file, but when i use getLogger().warning(string), following string is being unicode-escaped Example:

r = requests.post(...)
result = json.loads(r.text)  # Now result == '{"error": "Ошибка 1"}'
getLogger().warning(json.dumps(result))

This code will write to log file unicode-escaped string, where "Ошибка" will be written like "\u0417\u0430\u043a\u0430\u0437..." But i want to see these characters as is.

Your issue is that json.dumps is converting the Unicode to ASCII by escaping it. This can be avoided by adding an extra parameter, ensure_ascii=False, to the .dumps function:

r = requests.post(...)
result = json.loads(r.text)  # Now result == {"error": "Ошибка 1"}
getLogger().warning(json.dumps(result, ensure_ascii=False))

You can check the documentation for other arguments to the json.dumps function.
