Question

我试图通过我在播放框架文档中找到的ReactiveMongo依赖项/库将我的Play-scala应用程序连接到mongo db。

我已经在conf文件中添加了这样的

play.modules.enabled += "play.modules.reactivemongo.ReactiveMongoModule"
mongodb.uri = "mongodb://ege:ege123@localhost:27017/smug-studio"

但是在运行我的应用程序后，当我尝试通过邮递员api访问数据库时，会引发类似

的异常

{
    "Code": 0,
    "ERROR": "MongoError['Connection is missing metadata (like protocol version, etc.) The connection pool is probably being initialized.']"
}

在日志中我可以找到这样的

[warn] r.c.a.MongoDBSystem - [Supervisor-1/Connection-2] Error while processing getNonce response #1000
[error] r.c.a.MongoDBSystem - [Supervisor-1/Connection-2] Authentication failure

我应该怎么做才能解决此问题？

如果您可以在外壳上连接到mongo，则可能是因为您没有在URL上正确设置authMode或authMechanism：

mongodb://ege:ege123@localhost:27017/smug-studio?authMechanism=SCRAM-SHA-1

或

mongodb://ege:ege123@localhost:27017/smug-studio?authMode=SCRAM-SHA-1

在Scala中连接到MongoDB
