C# 具有2个以上参数的WCF自定义身份验证

如果companyID是来自客户端的标识符，则最简单的方法是将其作为用户名的一部分传递：

public class Authentication : UserNamePasswordValidator
{

   public override void Validate(string userName, string password, string companyID)
   { 

     //How can i pass a custom data like "companyID" to Validate method ?
   }

}

只需在验证器中拆分：

//on client:
string username = companyID + ":" + realUsername;

public override void Validate(string userName, string password) {
    string companyID, realUsername;
    string[] parts = userName.Split(':', 2);
    if (parts.Length == 2) {
        companyID = parts[0];
        realUsername = parts[1];
    }
}
