推荐答案

从带有mongodb 1.3.23驱动程序的MongoDB 2.4.8开始，它们看起来像这样:

As of MongoDB 2.4.8 with the mongodb 1.3.23 driver, they look like this:

{
  "name":"MongoError",
  "err":"E11000 duplicate key error index: test.test.$country_1  dup key: { : \"XYZ\" }",
  "code":11000,
  "n":0,
  "connectionId":10706,
  "ok":1
}
