如何在Postman / form-data上的嵌套对象中发布数组？

Question

我想将loc数据发布在postman / form-data中，而没有application / json头。

{
    "text": "abcd",
    "loc":  {
                "type": "Point",
                "coordinates": [-80, 25]
             }
    "img": multipart
}

当我在邮递员/表单数据中对此进行整理时

loc.coordinates [0]：-80 loc.coordinates [1]：25文本：... img：...

loc.coordinates不返回任何内容，请参见下文。

{
    "data": {
        "text": "test",
        "tags": [
            "testtest"
        ],
        "_id": "5b9e1462c1f13a0fe0912933",
        "img": "https://seoul-image-server.s3.cp.ap-northeast-2.amazonaws.com/1537086562695.png",
        "user": "5b8e4249f9f8184d0c825c6a",
        "date": "2018-09-16T08:29:22.791Z",
        "__v": 0
    }
}

当我在表单数据中感到厌倦时

loc：{“ type”：“ Point”，“ coordinates”：[-80，25]} ...

它返回

 "message": "Memo validation failed: loc: Cast to Embedded failed for value \"{\"type\": \"Point\", \"coordinates\": [-80, 25]}\" at path \"loc\""

为什么？？

这是我的图式

const geoSchema = new Schema({
  type: {
    type: String,
    default: 'Point'
  },
  coordinates: {
    required: true,
    type: [Number]
  }
});

const memoSchema = new Schema({
  img: {
    type: String,
    required: true
  },
  text: {
    type: String,
    default: ""
  },
  date: {
    type: Date,
    default: Date.now
  },
  tags: {
    type: [String],
    set: item => {
      if(Array.isArray(item)) {
        return item.join('')
      }
    },
    defulat: []
  },
  user: {
    type: Schema.Types.ObjectId,
    ref: 'User',
    required: true
  },
  loc: geoSchema
});

memoSchema.index({
  loc: '2dsphere'
});

module.exports = mongoose.model('Memo', memoSchema)

您正在发送JSON，这意味着您必须在双引号“ coordinates”中包装一个数组：“ [-80，25]”
