json.dumps在默认情况下，对于非ascii字符生成的是相对应的字符编码，而非原始字符

问题现象：

>>> import json
>>> js = json.loads('{"haha": "哈哈"}')
>>> print json.dumps(js)
{"name": "\u54c8\u54c8"}

解决办法:

设置 ensure_ascii=False 选项

>>> print json.dumps(js, ensure_ascii=False)
{"name": "哈哈"}

应用实例：

import json

#将字典转换成json文本
dic = {"companyId":95651,
                    "positionName":"自动化测试",
                    "workYear":"3-5年",
                    "education":"本科",
                    "jobNature":"全职",
                    "companyLogo":"i/image2/M01/2C/57/CgoB5lzUGO2AAoc3AACv6egD568191.png",
                    "salary":"15k-25k",
                    "city":"北京",
                    "financeStage":"B轮",
                    "industryField":"社交",
                    "companyShortName":"玩吧",
                    "approve":1,
                    "positionId":5537531,
                    "createTime":"2019-07-26 10:53:22",
                    "positionAdvantage":"七险一金,弹性不打卡,免费午餐,季度旅游",
                    "companySize":"150-500人"}
print(type(dic))
aString = json.dumps(dic,ensure_ascii=False)
print(type(aString))
print(aString)
json.dump(dic,open('test2.json',mode='w',encoding='utf-8'),ensure_ascii=False,)

输出：

<class 'dict'>
<class 'str'>
