中国語ASCIIのjsonの読み書きが文字化けする問題の解決策

# -*- coding: utf-8 -*-
import json
import codecs

f = codecs.open('data.txt', 'r', 'utf-8')
content = json.load(f)
print content[0]['id']
jsdata = json.dumps(content, sort_keys=True, indent=4)
f.close()


j = codecs.open('test.json', 'w')
j.write(jsdata)
j.close()

# -*- coding: utf-8 -*-
import json
import sys
reload(sys)
sys.setdefaultencoding( "utf-8" )

f = open('data.txt', 'r')
content = json.load(f)
print content[0]['id']
# 拼接json数据，转码为非ascii编码
jsdata = json.dumps(content, sort_keys=True, indent=4, ensure_ascii=False)
f.close()


j = open('test.json', 'w')
j.write(jsdata)
j.close()
