Django | Cookie 中文编码的问题

在Django中，向cookie写入中文字符后会报错；如向cookie中保存用户名，当用户名存在中文字符时:

Traceback (most recent call last):

　　此时可以使用Json模块的dumps()和loads()，将其序列化，再进行反序列化；

　　如记录用户名时，先将用户名进行序列化，再写入到cookie中。而在读取cookie之后，再将其反序列化即可

　　

　　dumps / loads 用法：

import json
username='用户1'
username=json.dumps(username)
username
'"\\u7528\\u62371"'
# 反序列化
username=json.loads(username)
username
'用户1'

　　

　　在Django中：

                if remember=='on':
                    # 记住用户名
                    # 如果username是中文，设置cookies时会报错
                    # cookie 中文编码处理
                    username=json.dumps(username)
                    response.set_cookie('username',username,max_age=7*24*3600)

                else:
                    # 取消记住用户名
                    response.delete_cookie('username')

        if 'username' in request.COOKIES:
            username=request.COOKIES.get('username')
            username=json.loads(username)
