在自定义验证器、服务堆栈 API 中隔离/访问设置的会话信息 [英] Isolating/Accessing set session information within custom validator, servicestack API

问题描述

我想知道从我们通过 servicestack 的 fluent-validation API 挂钩连接的自定义验证器中访问用户 AuthSession 的最佳方式.基本上，需求迫使我们使用名为DocNumberValidator"的类通过此验证器访问数据库.当用户进行身份验证时，用户的 ID 会保存到会话中，接下来我们需要这些信息来完成成功的 SQL 查询.如何访问此会话信息(见下文....).IoC 容器没有对 AuthSession 的引用?

I was wondering the best way of accessing the a user's AuthSession from within a custom validator we have hooked up via the servicestack's fluent-validation API hooks. Basically, the requirements are forcing us to access the database through this validator using a class called "DocNumberValidator ". The user's Id is saved into session when they authenticate, down the line we need this information to complete a successful SQL query. How does one access this session information (see below....). The IoC container does not have reference to the AuthSession?

• 我想问题是，有人如何将必要的会话值传递给 SS 验证框架调用的类?

示例代码:

public class MyValidator : AbstractValidator<Statuses>
{
    public IDocNumberValidator DocNumberValidator { get; set; }

    public StatusesValidator()
    {
        RuleFor(s => s.DocNumber)
              .Must(docNum => this.DocNumberValidator.Validate(docNum))
              .WithMessage("Document Number is invalid.")
              .WithErrorCode("S-001");
    }
}

 public class DocNumberValidator : IDocNumberValidator
{
    public IDbConnectionFactory Db { get; set; }

    public bool Validate(string docNum)
    {
        var isFound = false;
        this.Db.Run(conn =>
            {
                var sql = "SELECT COUNT([docNumber]) FROM [TABLE] WHERE [docNumber] = @DocNum AND [UserId] = @UserID";
                var cmd = conn.CreateCommand();
                cmd.CommandType = CommandType.Text;
                cmd.CommandText = sql;
                cmd.Parameters.Add(new SqlParameter("@DocNum", docNum));
                cmd.Parameters.Add(new SqlParameter("@UserID", ????????)); // how does one get access to saved users session here
                int cnt = (int) cmd.ExecuteScalar();
                if (cnt == 1)
                    isFound = true;

            });

        return isFound;
    }
}

推荐答案

不确定这是最好的方法.接受建议.

Not really sure this is the best way to do it. Open to suggestions.

• 使用 SessionFeature.GetSessionKey() 获取会话密钥
• 添加public ICacheClient CacheClient { get;放;} 到验证器.将被 IoC 容器注入
• 从 AuthUserSession(或您使用的任何类型)获取使用key缓存

• Use SessionFeature.GetSessionKey() to get the session key
• Add public ICacheClient CacheClient { get; set; } to the validator. Will be injected by IoC container
• Get the AuthUserSession (or whatever type you're using) from the cache using the key

添加到您的示例中

public class DocNumberValidator : IDocNumberValidator
{
    public IDbConnectionFactory Db { get; set; }
    public ICacheClient CacheClient { get; set; }

    public bool Validate(string docNum)
    {
        var isFound = false;
        var sessionKey = SessionFeature.GetSessionKey();
        var user = CacheClient.Get<AuthUserSession>(sessionKey); //Use whatever class you stored in the session

        this.Db.Run(conn =>
            {
                var sql = "SELECT COUNT([docNumber]) FROM [TABLE] WHERE [docNumber] = @DocNum AND [UserId] = @UserID";
                var cmd = conn.CreateCommand();
                cmd.CommandType = CommandType.Text;
                cmd.CommandText = sql;
                cmd.Parameters.Add(new SqlParameter("@DocNum", docNum));
                cmd.Parameters.Add(new SqlParameter("@UserID", user.UserAuthId)); // user whatever property you need access to
                int cnt = (int) cmd.ExecuteScalar();
                if (cnt == 1)
                    isFound = true;

            });

        return isFound;
    }
}
