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，例如“ mongodb // user：password @ server ...”。目前，在本地连接良好，我可以与MongoDB连接。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：//”。实际上，mongodb字符串看起来像是未知的。

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);

那是错误：

我已经解决了问题。造成该错误的原因是该应用无法连接到MongoDB。 MongoDB数据库位于无法访问的网络中

Kestrel .NET API-无法与mongodb // url连接
