实现SQL Server 2008 Reporting Services匿名访问报表有两种方法

一、通过修改SQL Server 2008的配置文件，去掉Windows的验证。

1.首先我们找到SQL安装目录下的两个Web.config配置文件，默认安装目录分别是
(C:Program FilesMicrosoft SQL ServerMSRS10.MSSQLSERVERReporting ServicesReportServer和C:Program FilesMicrosoft SQL ServerMSRS10.MSSQLSERVERReporting ServicesReportManager)
或者(C:Program FilesMicrosoft SQL ServerMSRS10_50.MSSQLSERVERReporting ServicesReportServer和C:Program FilesMicrosoft SQL ServerMSRS10_50.MSSQLSERVERReporting ServicesReportManager)
,然后，找到两个配置文件中的

<authentication mode="windows"/> <identity impersonate="true"/>

将其改为：

<authentication mode="None"/> <identity impersonate="false" />

2.找到（C:Program FilesMicrosoft SQL ServerMSRS10.MSSQLSERVERReporting ServicesReportServer）目录下的rsreportserver.config文件，找到配置文件中的

<Authentication>   
     <AuthenticationTypes>   
         <RSWindowsNegotiate/>   
         <RSWindowsNTLM/>  
     </AuthenticationTypes>   
     <RSWindowsExtendedProtectionLevel>Off</RSWindowsExtendedProtectionLevel>   
     <RSWindowsExtendedProtectionScenario>Proxy</RSWindowsExtendedProtectionScenario>   
     <EnableAuthPersistence>true</EnableAuthPersistence>   
</Authentication>

将其改为：

<Authentication>   
    <AuthenticationTypes>   
        <Custom/>  
    </AuthenticationTypes>   
    <RSWindowsExtendedProtectionLevel>Off</RSWindowsExtendedProtectionLevel>   
    <RSWindowsExtendedProtectionScenario>Proxy</RSWindowsExtendedProtectionScenario>   
    <EnableAuthPersistence>true</EnableAuthPersistence>   
</Authentication>

然后找到配置文件中的

<Security>  
    <Extension Name="Windows" Type="Microsoft.ReportingServices.Authorization.WindowsAuthorization, Microsoft.ReportingServices.Authorization"/>  
</Security>  
<Authentication>   
    <Extension Name="Windows" Type="Microsoft.ReportingServices.Authentication.WindowsAuthentication,Microsoft.ReportingServices.Authorization"/>   
</Authentication>

将其改为：

<Security>   
    <Extension Name="None" Type="Microsoft.Samples.ReportingServices.AnonymousSecurity.Authorization,Microsoft.Samples.ReportingServices.AnonymousSecurity"/>
</Security>  
<Authentication>  
     <Extension Name="None" Type="Microsoft.Samples.ReportingServices.AnonymousSecurity.AuthenticationExtension,Microsoft.Samples.ReportingServices.AnonymousSecurity"/>   
</Authentication>

这里需要引用一个DLL文件，就是Microsoft.Samples.ReportingSerices.

3.将dll放入到目录C:Program FilesMicrosoft SQL ServerMSRS10.MSSQLSERVERReporting ServicesReportServerin，接下来继续修改我们的配置文件，在（C:Program FilesMicrosoft SQL ServerMSRS10.MSSQLSERVERReporting ServicesReportServer）目录下，找到rssrvpolicy.config找到

<CodeGroup 
        class="FirstMatchCodeGroup"
        version="1"
        PermissionSetName="Nothing">
    <IMembershipCondition 
            class="AllMembershipCondition"
            version="1"
    />

在其下边追加如下节点（红色部分，按照你的实际路径而定）

<CodeGroup class="UnionCodeGroup" version="1" PermissionSetName="FullTrust" Name="Private_assembly" Description="This code grou p grants custom code full trust.">   
    <IMembershipCondition class="UrlMembershipCondition" version="1" Url="C:Program FilesMicrosoft SQL ServerMSRS10_50.MSSQLSERVER2008Reporting ServicesReportServerinMicrosoft.Samples.ReportingServices.AnonymousSecurity.dll"/>   
</CodeGroup>

到此为止，我们匿名登录的方式，配置工作就完成了。

二、利用接口IReportServerCredentials 和IReportServerConnection将Windows的用户名和密码传进去以实现匿名访问报表。
1.利用IReportServerCredentials 接口
接口定义为：

using System;
using Microsoft.Reporting.WebForms;
using System.Net;
using System.Security.Principal;
using System.Configuration;

namespace SqlReport
{
    [Serializable]
    internal class MyConfigFileCredentials : IReportServerCredentials
    {
        public MyConfigFileCredentials()
        {
        }

        public WindowsIdentity ImpersonationUser
        {
            get { return null; }
        }

        public ICredentials NetworkCredentials
        {
            get
            {
                return new NetworkCredential("Administrator", "123456"); //windows的用户名和密码  
            }
        }

        public bool GetFormsCredentials(out Cookie authCookie, out string userName, out string password,
            out string authority)
        {
            authCookie = null;
            userName = null;
            password = null;
            authority = null;
            return false;
        }
    }
}

在调用报表的代码如下：

using System;
using System.Web;
using Microsoft.Reporting.WebForms;

namespace SqlReport
{
    public partial class _Default : System.Web.UI.Page
    {

        protected void Page_Load(object sender, EventArgs e)
        {
            if ((!IsPostBack) && Request.QueryString.Count > 0)
            {
                string reportPath = Request.QueryString[0];
                this.ReportLabel.Text = Request.QueryString[0];

                this.ReportViewer3.ProcessingMode = ProcessingMode.Remote;
                MyConfigFileCredentials rsc = new MyConfigFileCredentials();

                this.ReportViewer3.ServerReport.ReportServerCredentials = rsc;
                this.ReportViewer3.ServerReport.ReportPath = reportPath;
                this.ReportViewer3.ServerReport.ReportServerUrl =
                    new Uri((Properties.Settings.Default.MyReportServerUrl));
                this.ReportViewer3.ServerReport.Refresh();
            }
        }
    }
}

2.利用IReportServerConnection接口，接口定义：

using System;
using System.Collections.Generic;
using System.Net;
using System.Security.Principal;
using Microsoft.Reporting.WebForms;

namespace SqlReport
{
    [Serializable]
    public class MyReportServerConnection : IReportServerConnection
    {
        public Uri ReportServerUrl
        {
            get
            {
                string url = Properties.Settings.Default.MyReportServerUrl;
                if (string.IsNullOrEmpty(url))
                    throw new Exception("Missing url from the Web.config file");
                return new Uri(url);
            }
        }

        public int Timeout
        {
            // set timeout to 60 seconds  
            get { return 60000; }
        }

        public IEnumerable<Cookie> Cookies
        {
            // No custom cookies  
            get { return null; }
        }

        public IEnumerable<string> Headers
        {
            // No custom headers  
            get { return null; }
        }

        public MyReportServerConnection()
        {
        }


        public WindowsIdentity ImpersonationUser
        {
            get { return null; }
        }

        public ICredentials NetworkCredentials
        {
            get
            {
                //this will force the use of impersonation,   
                // otherwise, remove the return null and   
                // implement the other app settings to specify the credential details  
                // return null;  
                string userName = Properties.Settings.Default.myReportViewerUser;
                if (string.IsNullOrEmpty(userName))
                    throw new Exception("Missing user name from Web.config file");
                string password = Properties.Settings.Default.MyReportViewerPassword;
                if (string.IsNullOrEmpty(password))
                    throw new Exception("Missing password from Web.config file");
                string domain = Properties.Settings.Default.MyReportViewerDomain;
                if (string.IsNullOrEmpty(domain))
                    throw new Exception("Missing domain from Web.config file");
                return new NetworkCredential(userName, password, domain);
                //return new NetworkCredential(userName, password);  
            }
        }

        public bool GetFormsCredentials(out Cookie authCookie, out string userName, out string password,
            out string authority)
        {
            authCookie = null;
            userName = null;
            password = null;
            authority = null;
            return false;
        }
    }
}

在调用报表的代码如下：

using System;
using System.Web;
using Microsoft.Reporting.WebForms;

namespace SqlReport
{
    public partial class _Default : System.Web.UI.Page
    {

        protected void Page_Load(object sender, EventArgs e)
        {
            if ((!IsPostBack) && Request.QueryString.Count > 0)
            {
                string reportPath = Request.QueryString[0];
                this.ReportLabel.Text = Request.QueryString[0];

                this.ReportViewer3.ProcessingMode = ProcessingMode.Remote;
                MyReportServerConnection rsc = new MyReportServerConnection();

                this.ReportViewer3.ServerReport.ReportServerCredentials = rsc;
                this.ReportViewer3.ServerReport.ReportPath = reportPath;
                this.ReportViewer3.ServerReport.ReportServerUrl =
                    new Uri((Properties.Settings.Default.MyReportServerUrl));
                this.ReportViewer3.ServerReport.Refresh();
            }
        }
    }
}

OK完成啦。
