Solution to the problem of reading and writing Chinese ASCII garbled json

Today I am going to write a small backend for the front end, which is to read the data and then convert it into json and send it to him for display. The data is very simple, but we encountered a problem during processing. The file involves Chinese processing. The json format written after each processing is ASCII code, which is completely unusable. The code is as follows:

# -*- 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()

I checked online and the modified code is as follows:

# -*- 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()
