从ASP.net应用程序连接到Analysis Service [英] Connecting to Analysis Service from ASP.net application
问题描述
我正在尝试实现ASP.net应用程序，该应用程序需要连接Microsoft Analysis Service(SSAS)才能从多维数据集以及维度中检索数据.
I am trying to implement ASP.net application which will need to connect Microsoft Analysis Service (SSAS) to retrive data from cube as well as dimensions.
static void Main(string[] args)
{
StringBuilder connectionStringBuilder = new StringBuilder();
connectionStringBuilder.Append("Data Source=MyDataSource;");
connectionStringBuilder.Append("Initial Catalog=MyOlapDatabase;");
connectionStringBuilder.Append(@"User Id=OlapServerMachineName\MyUserName;");
connectionStringBuilder.Append("Password=MyPassword;");
connectionStringBuilder.Append("Provider=MSOLAP.5;");
connectionStringBuilder.Append("Persist Security Info=True;");
connectionStringBuilder.Append("MDX Compatibility=1;");
connectionStringBuilder.Append("Safety Options=2;");
connectionStringBuilder.Append("MDX Missing Member Mode=Error;");
connectionStringBuilder.Append("Update Isolation Level=2;");
using (var connection = new AdomdConnection(connectionStringBuilder.ToString()))
{
connection.Open();
}
}
此代码引发以下异常
无法建立连接.确保服务器正在运行.
A connection cannot be made. Ensure that the server is running.
内部异常提示
无法从传输连接中读取数据:远程主机强行关闭了现有连接.
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
而内部异常的内部异常是
and inner exception of inner exception is
无法从传输连接中读取数据:远程主机强行关闭了现有连接.
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
另一方面，我可以使用相同的用户名和密码从Excel连接到此Analysis Service，如下所示
On the other hand, I can connect to this Analysis Service from Excel with the same user name and password as shown below
我尝试按照此处设置对Olap Server的HTTP访问>.通过IIS设置上的匿名身份验证，我可以成功连接.但是，当我禁用匿名"选项并启用基本身份验证"时，再次无法从客户端工具进行连接，但是Excel在基本身份验证"下工作正常.
I tried setting up HTTP access to Olap Server as described here. With anonymous authentication on IIS setting, I am able to connect successfully. But when I disable Anonymous option and enable Basic Authentication, again I am not able connect from my client tool but Excel is working fine with Basic Authentication.
但是尝试使用HTTP访问只是临时解决方案.我不想使用该选项.我希望能够像从客户端应用程序一样在excel中连接SSAS.
But trying to use HTTP access was just for temporary solution. I do not want to use that option. I want to be able connect SSAS like I can in excel from my client app.
我的问题是，我连接SSAS的实现(不起作用)和excel身份验证(可以正常工作)之间有什么区别?
My question is, what is the difference between my implementation to connect SSAS (does not work) and excel authentication (works perfect) ?
谢谢.
推荐答案
不要将用户名和密码放在连接字符串上，请尝试至少在此模拟程序中包装您的 .Open()函数调用:
Instead of putting the user and password on the connection string try wrapping at least your .Open() function call in this impersonator:
与连接字符串上的密码相比，我获得的成功更大.
I have had more success with that than passwords on the connection string.
除非您希望包含它，否则您不需要msmdpump HTTP层.
You shouldn't need the msmdpump HTTP layer unless you prefer it be involved.
