MongoError:“geoNear 命令失败:{ ok:0.0,errmsg:\“处理查询时出错”,“code”:16604,“codeName”:“Location16604”

问题描述 投票:0回答:2

我对 mongodb geonear 聚合查询感到沮丧,对于每个响应,我都会收到如下错误:

{"name":"MongoError","message":"geoNear command failed: { ok: 0.0, errmsg: \"error processing query: ns=Lab.assoprofiles limit=100Tree: GEONEAR  field=loc maxdist=50000 isNearSphere=1\nSort: {}\nProj: { $pt: { $meta: \"geoNearPoin...\", code: 2, codeName: \"BadValue\" }","ok":0,"errmsg":"geoNear command failed: { ok: 0.0, errmsg: \"error processing query: ns=Lab.assoprofiles limit=100Tree: GEONEAR  field=loc maxdist=50000 isNearSphere=1\nSort: {}\nProj: { $pt: { $meta: \"geoNearPoin...\", code: 2, codeName: \"BadValue\" }","code":16604,"codeName":"Location16604"}

这就是我设计这个系列的方式:

const mongoose = require("mongoose");
var Schema = mongoose.Schema;

var AssoSchema = new mongoose.Schema({
   userId:{ type: mongoose.Schema.Types.ObjectId, ref: "User"},
   picture : String,
   telephone: {
      type: String,
      unique: false
   },
   loc: {
      type: [Number], // [<longitude>, <latitude>]
      index: "2d" // create the geospatial index
   },

},{timestamps: true})

var Asso = mongoose.model('AssoProfile', AssoSchema);
module.exports = Asso;

查询是这样的:

const latitude = parseFloat(req.body.latitude);
const longitude = parseFloat(req.body.longitude);
AssoProfile.aggregate([
     {
        $geoNear: {
           near: { type: 'Point', coordinates: [latitude, longitude] },
           spherical: true, distanceField: 'distance', maxDistance:7000,
        }
     }

   ], function(err, l ){
      console.log(JSON.stringify(err));
      console.log(l);
   })

我不明白为什么这么简单的查询会抛出这个错误。 感谢您的帮助。

我运行了与上面发布的相同的代码,但它对我不起作用......而且我认为

index: 2d
不是猫鼬模型中的选项。相反,我创建了这样的索引并为我工作。

const mongoose = require("mongoose")
var Schema = mongoose.Schema

var AssoSchema = new mongoose.Schema({
   userId: { type: mongoose.Schema.Types.ObjectId, ref: "User" },
   picture : String,
   telephone: {
      type: String,
      unique: false
   },
   loc: Array,

}, { timestamps: true })


AssoSchema.index({ 'loc': '2dsphere' })

var Asso = mongoose.model('AssoProfile', AssoSchema)
module.exports = Asso;

就我而言,我的索引很好,但我用来引用它的

'key'
是错误的。删除该要求,让 Mongo 自动使用所需的索引,并添加所需的
query
对我有用。

$geoNear: {
    near: { type: 'Point', coordinates: [latitude, longitude] },
    spherical: true,
    distanceField: 'distance',
    maxDistance: 7000,
    // key: 'geometry',  // removing this
    query: {             // adding this
        required_index_field: '17',
    },
}

query
对我来说是必要的,因为我的索引是复合索引(例如
required_index_field_geometry_2dsphere
),因此需要另一个可访问的字段。
