如何找到只有一个文档Restivus和Curl [英] How to find just one document with Restivus and Curl

问题描述

我有一个简单的初学者使用Restivus的问题。

I have a simple beginners problem with using Restivus.

在我的app.js中我已经声明：

In my app.js I have declared:

Players = new Mongo.Collection("players");

及更高版本：

if (Meteor.isServer) {
  // Global configuration
  Api = new Restivus({
    useDefaultAuth: true,
    prettyJson: true
  });

  // Generates: GET/POST on /api/v1/players, and GET/PUT/DELETE on     /api/v1/players/:id
  // for Meteor.users collection (works on any Mongo collection)
  Api.addCollection(Players);
  // That's it! Many more options are available if needed...
}

然后我开始meteor mongo

I then start "meteor mongo"

meteor:PRIMARY> db.players.insert({username:"Kalle", location:"Home"})
WriteResult({ "nInserted" : 1 })

meteor:PRIMARY> db.players.insert({username:"Pelle", location:"Away"})
WriteResult({ "nInserted" : 1 })

meteor:PRIMARY> db.players.find({});
{ "_id" : ObjectId("56598d83846a7b53e8a1176b"), "username" : "Kalle","location" : "Home" }
{ "_id" : ObjectId("56598d8c846a7b53e8a1176c"), "username" : "Pelle", "location" : "Away" }

我得到：

curl -X GET http://localhost:3000/api/players
{
  "status": "success",
  "data": [
    {
      "_id": {
        "_str": "56598d83846a7b53e8a1176b"
      },
      "username": "Kalle",
      "location": "Home"
    },
    {
      "_id": {
        "_str": "56598d8c846a7b53e8a1176c"
      },
      "username": "Pelle",
      "location": "Away"
    }
  ]

但是当我尝试找到一个特定文档时：

BUT when I then try to find one particular document:

curl -X GET http://localhost:3000/api/players/56598d83846a7b53e8a1176b
{
  "status": "fail",
  "message": "Item not found"
}

为什么找不到文档和处理什么

Why doesn't it find the document and whats the deal with the:

"_id": {
    "_str": "56598d83846a7b53e8a1176b"
 }

推荐答案

meteor mongo 简单地打开一个MongoDB shell，这些文档是使用 _id （这是MongoDB id的默认类型）的ObjectId创建的。

Since meteor mongo simply opens a MongoDB shell, the documents were created with an ObjectId for an _id (which is the default type for MongoDB ids).

Meteor默认为 _id 的随机字符串。因此，您的示例中的 _id 不仅仅是您看到的字符串，而是整个ObjectId包含它。

Meteor defaults to random strings for _ids. Therefore, the _id in your example is not simply the string that you see, but the entire ObjectId containing it.

为了使它工作，在mongo shell中显式地设置 _id 或者（可能更好）使用 meteor shell 请直接从Meteor服务器插入文档。

To make it work, either explicitly set an _id in the mongo shell or (probably better) use meteor shell to insert the documents directly from the Meteor server.
