搜索 NearGeoPoint 时出现内部错误

问题描述

我正在使用解析 sdk，当我尝试搜索 nearGeoPoint 时，我得到

I'm using parse sdk and when i try to search nearGeoPoint I get

2016-05-01 18:33:17.275 Partee[2557:1416403] [Error]: internal error (Code: 1, Version: 1.13.0)
2016-05-01 18:33:17.275 Partee[2557:1416403] [Error]: Network connection failed. Making attempt 1 after sleeping for 1.965591 seconds.

我使用的代码是

let query = PFQuery(className: "Parties")
let myLocation = currentuser?.objectForKey("location") as! PFGeoPoint
query.whereKey("location", nearGeoPoint: myLocation, withinKilometers: 100)
query.findObjectsInBackgroundWithBlock({ (objects, error) in
      if error == nil {
           print("\(objects?.count) searches found")
      }
    }
})

where currentuser 有location"作为他的当前位置已经保存，所以我试图搜索该用户 100 公里附近的派对，但我不断收到错误，如果我评论 nearGeoPoint它工作得很好.

where currentuser has "location" as his current location already saved, so I'm trying to search parties near 100 kilometer of that user but I keep getting that error, if i comment nearGeoPoint line then it works perfectly fine.

推荐答案

我在 mLab 上从 Parse 迁移到 MongoDB 时遇到了这个问题.

I had this issue on migrating from Parse to MongoDB on mLab.

您需要向 GeoPoint 字段添加二维索引.如果您使用的是 MongoDB，请执行以下任一操作.

You need to add a 2d index to your GeoPoint field. If you are using MongoDB, do either of the following.

Mongo Shell:

db.test.createIndex({ "userLocation": "2d" })

例如.其中test"是您的集合名称，userLocation"是您在该集合中的 GeoPoint 字段的名称.

Eg. Where 'test' is your collection name and 'userLocation' is the name of your GeoPoint field inside this collection.

mLab 用户界面仪表板:

转到您的数据库.转到具有导致问题的 GeoPoint 字段的集合.转到顶部栏中的索引".选择添加索引"输入，例如:

Go to your database.Go to the Collection that has the GeoPoint field causing the problem. Go to 'Indexes' on the top bar. Select 'Add Index' Input for example:

{ "userLocation" : "2d" }

例如.其中userLocation"是此集合中您的 GeoPoint 字段的名称.

Eg. Where 'userLocation' is the name of your GeoPoint field inside this collection.

那应该可以解决它.
