[
{
_id:ObjectId("5edd1df67b272e2d4cf36f70"),
date:"01-06-2020",
pid:1,
pname:"Micheck"
},
{
_id:ObjectId("5edd1dk67b272e2d4cf31f72"),

data.controller.js:数据.controller.js:
module.exports.getReportTableData = (req, res, next) => {
let collectionname = req.query.collection;
let date1 = "01-06-2020"; //dd-mm-yyyy
let date2 = "07-06-2020"; //dd-mm-yyyy
let tableReportdata = dbc.model(collectionname);
tableReportdata.find({ date: date1,date2 }, function(err, docs) {
if (err) {
console.log(err);
return;
} else {
console.log("Successful loaded data");
res.json({ data: docs, success: true, msg: 'Data loaded.' });

This solution Needs Mongo server version > 4.0.0此解决方案需要 Mongo 服务器版本 > 4.0.0
According to OPs comment he's using version 4.2.7根据 OP 的评论,他使用的是 4.2.7 版
Mongo is currently treating your fields as a string, and not a date, so first you'll have to convert them to dates. Mongo 当前将您的字段视为字符串,而不是日期,因此首先您必须将它们转换为日期。
I would recommend changing your field type to date while writing to the DB, or adding a new field with date type for better performance and less overhead我建议在写入数据库时将字段类型更改为日期,或者添加具有日期类型的新字段以获得更好的性能和更少的开销
To do this conversion at runtime, you'll have to use the aggregation pipeline with the, addFields dateFromString match gte and lte operators.要在运行时进行此转换,您必须将聚合管道与addFields dateFromString 匹配gte和lte运算符一起使用。
Your code should look like:您的代码应如下所示:
let date1 = new Date("2020-06-01T00:00:00.000Z"); // date objects
let date2 = new Date("2020-06-07T00:00:00.000Z");
let tableReportdata = dbc.model(collectionname);
tableReportdata.aggregate([{
$addFields: {
convertedDate: {
$dateFromString: {
dateString: "$date",
format: "%d-%m-%Y",
timezone: "UTC"
}
}
}
},
{
$match: {
convertedDate: {
$gte: date1,
$lte: date2,
}
}
}
], function(err, docs) {
if (err) {
console.log(err);
return;
} else {
console.log("Successful loaded data");
res.json({
data: docs,
success: true,
msg: 'Data loaded.'
});
}
});
