Kestrel .NET API - 无法连接 mongodb// url

Question

我已经配置了连接到 Mongo 数据库的 .net 核心 API。我已经从 ConnectionString 连接到它，如 "mongodb//user:password@server ..."。目前，在本地连接很好，我可以连接 MongoDB。问题是当我发布它时，服务器日志流向我显示了与 Kestrel 代理相关的内容，并且无法解析 "mongodb://"。事实上，mongodb 字符串看起来像 unknown。

我已经在 app.settings.json 文件中配置了连接：

"ConnectionStrings"：{ "db": "mongodb://admin:blbablabla@url:27017/?authSource=admin"


    var uri = new MongoUr(_configuration.GetSection(CONNECTIONSTRINGS)[db];
    _mongoDBClient = new MongoClient(uri);

那就是错误：

我已经解决了问题。该错误是因为该应用无法连接到 MongoDB。 MongoDB 数据库位于无法访问的网络中
