我正在使用 Twitter 身份验证,并希望将 twitter id 作为唯一密钥存储在 mongodb 中。但是我看到多个具有相同 ID 的条目。这是我的架构和代码
架构:
var TwitterSchema = new Schema({
accessToken: String,
accessTokenSecret: String,
name: String,
twitterId: { type: String, required: true, index: { unique: true, sparse: true } }
});
代码:
mongoose.connect('mongodb://localhost/twd')
mongoose.model('Post', TwitterSchema);
var Post = mongoose.model('Post');
var post = new Post();
post.accessToken = accessToken
post.accessTokenSecret = accessTokenSecret
post.name = twitterUserData.name
post.twitterId = twitterUserData.id
post.save(function(err){
if (err){
throw err;
promise.fail(err);
}
console.log('saved');
mongoose.disconnect();
});
promise.fulfill(post);
数据库外壳输出
> db.posts.find();
{ "twitterId" : "21475255", "name" : "MMMK", "accessTokenSecret" : "ZYhiXMWfXvSr1aaCB93hgU243j8aapP0ALdSFlWEE", "accessToken" : "22475255-9YvKMceUInUIxcEtKAK0oMRRG2ZZxn5c52vnwPw", "_id" : ObjectId("4feddf6155203990e000001") }
{ "twitterId" : "21475255", "name" : "MMMK, "accessTokenSecret" : "ZYhiXMWfXvSr1aaCB93hgU2438aapP0ALdSFlWEE", "accessToken" : "22475255-9YvKMceUInUIxcEtKAK0oMRRG2ZZxn5c52vnwPw", "_id" : ObjectId("4feddf7b5905a1a10e000001") }
