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~

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]+";")
这里还做了判断是否需要id,因为一般id字段是自增的,所以默认是不需要id,如果需要id的话,将withId改为
True
即可(区分大小写)注意:表的字段要和mock生成的数据一一对应(名称不一样可以,但顺序要一样。)建议看情况修改字符串
s
的insert语句的字段顺序。
转换结果
插入到数据库,成功了哦!
Postman也能访问到数据了~
一共361条数据(还有我之前插入的),每页显示20个,查第19页,只能返回最后一个陈强,也就是刚刚插入的最后一个会员信息。
