给出包含内容的输入文件:
{ "symbol": "°C" }
这段代码:
import sys
import json
with open(sys.argv[1], 'r') as ifile, open(sys.argv[2], 'w') as ofile:
json.dump(json.load(ifile), ofile, indent=4, ensure_ascii=False)
我收到错误:
$ python2.7 play.py input.json output.json
Traceback (most recent call last):
File "play.py", line 5, in <module>
json.dump(json.load(ifile), ofile, indent=4, ensure_ascii=False)
File "/usr/lib/python2.7/json/__init__.py", line 190, in dump
fp.write(chunk)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xb0' in position 1: ordinal not in range(128)
但是Python 3运行良好:
$ python3.3 play.py input.json output.json
$ cat output.json
{
"symbol": "°C"
}
答案 0 :(得分:4)
您可以使用codecs
模块通过声明文件的编码来处理它:
import sys
import json
import codecs
with codecs.open(sys.argv[1], 'r', 'utf-8') as ifile, codecs.open(sys.argv[2], 'w', 'utf-8') as ofile:
json.dump(json.load(ifile), ofile, indent=4, ensure_ascii=False)
