由于未找到用户，以下服务器方法引发重复键错误。一个典型的查询是：{services: {facebook: {id: 'XXXX'}}}

Meteor.methods
  getUser: (query, data = {}) ->
    user = Meteor.users.findOne(query)
    return user if user?
    user = _.extend(data, query)
    user._id = Meteor.users.insert user
    return user

据我了解，服务器方法可以访问集合中的所有文档，那么为什么找不到用户但由于重复的 facebook id 而插入失败？

这在我的 osx 开发环境中完美运行，但在我的 ubuntu 服务器（捆绑）上失败并使用 NODE_ENV=production 运行。

这是日志输出：

data:    undefined (the result of findOne)

这些是不同的 MongoDB 查询，您肯定想要切换到的点样式。请参阅Mongo Dot Notation文档。

Meteor.users.find({"services.facebook.id": "foo"})

将返回具有您正在查找的嵌入属性的任何文档 value foo。

Meteor.users.find({services: {facebook: {id: "foo"}}})

仅匹配具有该结构的文档。如果嵌入的 facebook 文档有其他字段，它将不匹配。您的生产数据库中的文档可能有更多字段，因此您没有得到匹配。
