Question

 db.getCollection('places').find({
    "features.geometry":{
  $near: {
     $geometry: {
        type: "Point" ,
        coordinates:[
    -834502.889188578,3970333.88258796
                        ]}
     ,
     $maxDistance: a given number
  }
}
});

这就是代码，我想要的是返回几何图形接近的文档 [-834502.889188578,3970333.88258796] 和tha（错误

Error: error: {
    "waitedMS" : NumberLong(0),
    "ok" : 0,
    "errmsg" : "invalid point in geo near query $geometry argument: { type: \"Point\", coordinates: [ -834502.889188578, 3970333.88258796 ] }  longitude/latitude is out of bounds, lng: -834503 lat: 3.97033e+006",
    "code" : 2
}

Answer 1

这些不是有效的lat和long值。纬度范围为+/- 90，经度范围为+/- 180。

这些不是有效的lat和long值。纬度范围为+/- 90，经度范围为+/- 180.在mongo $ geoNear坐标中，第一个值是经度，第二个值是纬度。传递给：

db.getCollection('places').find({
    "features.geometry":{
  $near: {
     $geometry: {
        type: "Point" ,
        coordinates:[
    longitude, latitude
                        ]}
     ,
     $maxDistance: a given number
  }
}
});
