一种通过ReportViewer控件显示报表,在系统中添加一个专用用户,权限限制在浏览级别,然后在代码中实现身份接口,指定控件以该用户身份登录,这是变相的匿名访问;(详细见http://www.cnblogs.com/lonely7345/archive/2010/01/10/1643603.html)
第二种是通过WebService来访问报表,是本人一篇博文(http://www.cnblogs.com/dege301/archive/2009/09/04/1560456.html)中介绍方法的衍生,细节不在说明,类似于第一种方法需要指定专门用户,也不是真正意义上的匿名访问;
第三种就是MSDN上能找到的那种,更改4个配置文件并添加一个.dll文件,经本人测试,如果完全按照给的说明操作不可行,会出现“报表服务器配置错误”,但经过一些列改动之后该方法可行,并且是真正意义上的匿名访问,将在下文中给出详细步骤。
涉及到的配置文件如下(目录视具体安装情况):
1. C:\Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer下的web.config、rsreportserver.config、rssrvpolicy.config
2. C:\Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportManager下的web.config
注意:在配置之前先备份以上文件,以防失败!!!
配置过程:
1. 找到两个Web.config文件中的如下代码:
<authentication mode="Windows" />
<identity impersonate="true" />
替换成:
<authentication mode="None" />
<identity impersonate="false"/>
2. 找到rsreportserver.config文件中的如下代码:
<Authentication>
<AuthenticationTypes>
<RSWindowsNegotiate/>
<RSWindowsNTLM/>
</AuthenticationTypes>
<EnableAuthPersistence>true</EnableAuthPersistence>
</Authentication>
替换成:
<Authentication>
<AuthenticationTypes>
<Custom/>
</AuthenticationTypes>
<EnableAuthPersistence>true</EnableAuthPersistence>
</Authentication>
3. 把文件Microsoft.Samples.ReportingServices.AnonymousSecurity.dll放到C:\Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\bin目录下(注意:目录视具体安装情况而定)
4. 找到rsreportserver.config文件中的如下代码:
<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>
替换成:
<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>
5. 找到文件rssrvpolicy.config中的如下代码:
</NamedPermissionSets>
<CodeGroup
class="FirstMatchCodeGroup"
version="1"
PermissionSetName="Nothing">
<IMembershipCondition
class="AllMembershipCondition"
version="1"
/>
在后面添上如下代码(注意Url地址可能不同):
<CodeGroup class="UnionCodeGroup" version="1" PermissionSetName="FullTrust" Name="Private_assembly" Description="This code group grants custom code full trust."> <IMembershipCondition class="UrlMembershipCondition" version="1" Url="C:\Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER2008\Reporting Services\ReportServer\bin\Microsoft.Samples.ReportingServices.AnonymousSecurity.dll" />
</CodeGroup>
6. 重启Reporting Service服务。
