如何在Servicestack中配置mongodb

Question

我試圖將MongoDB用作ServiceStack的Authentication模塊的持久性后端，因此我在web.config添加了以下節點：

<connectionStrings>
    <add name="myDb" connectionString="mongodb://localhost/mydb?safe=true" />
</connectionStrings>

這是我的Configure方法：

public class MyAppHost : AppHostBase
{
    public MyAppHost () : base("My Web Services", typeof(MyService).Assembly)
    {
    }

    public override void Configure(Container container)
    {
        Plugins.Add(new AuthFeature(() => new AuthUserSession(), new IAuthProvider[] {
            new BasicAuthProvider()
        }));
        Plugins.Add(new RegistrationFeature());

        var connectionString = ... // how do I retrieve "mongodb://localhost"?
        var dbName = ...           // how do I retrieve "mydb"?
        var mongoClient = new MongoClient(connectionString);
        var server = mongoClient.GetServer();
        var db = server.GetDatabase(dbName);

        container.Register<ICacheClient>(new MemoryCacheClient());
        container.Register<IUserAuthRepository>(new MongoDBAuthRepository(db, true));
    }
}

如何從web.config檢索連接字符串和數據庫名稱？

Answer 1

建議的訪問您的App或Web.Config appSettings的方法是：

var appSettings = new AppSettings();
var connStr = appSettings.GetString("myDbConnectionString");

也就是說，如果您將所有配置設置都保留在<appSettings/>標記中。

要訪問保存在<connectionStrings>中的連接字符串，可以使用ConfigUtils，例如：

var connStr = ConfigUtils.GetConnectionString("MyDb");
