错误验证

测试：
curl --location --request POST 'http://localhost:9999/register' \
--header 'Content-Type: application/json' \
--data-raw '{
    "username": "asong",
    "nickname": "golang梦工厂",
    "email": "7418.com",
    "password": "123",
    "age": 140
}'

成功的测试：

curl --location --request POST 'http://localhost:9999/register' \
--header 'Content-Type: application/json' \
--data-raw '{
    "username":"jone",
    "nickname": "golang梦工厂",
    "email": "7418@qq.com",
