十几行代码将mock生成的json数据转为sql的insert语句

在这里插入图片描述

事情是这样的，我之前发的前端代码，调用接口的时候不是用mock.js生成的数据吗？然后最近学习用SpringBoot给它安排个后端，于是不可避免的就要创建数据库查表了！但是，没有数据怎么办？？我灵机一动，想到了现在的方法，将mock生成的json数据，逆向转换成sql的insert语句，直接往表里插入~

插入到数据库，成功了哦！
Postman也能访问到数据了~

这里我们只取数据部分就行了，也就是rows[]中的数据（一个个的{"id":xx,"cardNum":xx,...}），复制到一个json文件中

Python代码实现转换

'''
json文件要是gbk编码，生成的sql文件好像也是gbk的，不能直接导入。。
需要替换字符串s的初始sql，在navcat的表上右键复制insert方法，然后把VALUES后边的全删了就行了。
如果需要同时设置id，则把withId改为True
没有自动装配，请确保json数据和表的字段顺序一致！
'''
withId = False
with open("member.json", "r")as f:
    json=f.read()
s=f"INSERT INTO `mxg_member`.`tb_member` (`id`, `card_num`, `name`, `birthday`, `phone`, `integral`, `money`, `pay_type`, `address`) VALUES "
if not withId:
    s = s.split('id')[0][:-1] + s.split('id')[1][2:]
s += "\n"
json = json.split("\n")
for i in json:
    if "id" in i:
        s+=f"({i.split(':')[1] if withId else ''}"
    elif ":" in i:
        s+=i.split(":")[1]
    elif "}" in i:
        s+="),\n"
with open("member.sql", "w")as f:
    f.write(s[:-2]+";")
