只需要年月日格式的日期

如果在引号和字段中添加了一些拼写错误，请尝试使用：

db. persons.aggregate([
{
$project: {
_id: 0,
name: 1,
email: 1,
totalage: "$dob.age",
birthday: {
$convert: {
input: "$dob.date",
to: "date"
}
}
}
},
{
$project: {
_id: 0,
name: 1,
email: 1,
totalage: 1,
janamdin: {
$dateToString: {
format: "%Y-%m-%d",
date: "$birthday"
}
}
}
}
])
