今天的Django教训汇总：simplejson将字符串形式的字典转化为字典-20211031

• views.py

    employee_list = Employee.objects.filter(dept_code__startswith=data_dict[0])
    print(type(data_dict))
    print('dept_code:',data_dict[0])
    print(employee_list)

import simplejson
# loads 把字符串转换成字典

#{}里都是双引号，会成功
str_dic = '{"name":"zeropython","age":"testa"}'
new_dic = simplejson.loads(str_dic)

#{}里都是单引号，会报错
str_dic = "{'name':'zeropython','age':'testa'}"
#new_dic = simplejson.loads(str_dic)
#simplejson.errors.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

#{}里都是单引号，需要转化
str_dic = "{'name':'zeropython','age':'testa'}"
str_dic = str_dic.replace('"','|').replace("'",'"').replace('|','"')
new_dic = simplejson.loads(str_dic)
print(type(new_dic))

• 实际上json格式的引号需要为双引号，否则会报错如下。str_dic = "{‘name’:‘zeropython’,‘age’:‘testa’}"会报错
  
• 故需要替换单引号为双引号。
