實現Reporting Service2008 的匿名訪問是件比較費勁的事情，網上提供的方法挺多的，但總結起來起來能用的就三種：

　　一種通過ReportViewer控件顯示報表，在系統中添加一個專用用戶，權限限制在瀏覽級別，然后在代碼中實現身份接口，指定控件以該用戶身份登錄，這是變相的匿名訪問；（詳細見 http://www.cnblogs.com/lonely7345/archive/2010/01/10/1643603.html ）

　　第二種是通過WebService來訪問報表，是本人一篇博文（ http://www.cnblogs.com/dege301/archive/2009/09/04/1560456.html ）中介紹方法的衍生，細節不在說明，類似于第一種方法需要指定專門用戶，也不是真正意義上的匿名訪問；

　　第三種就是MSDN上能找到的那種，更改4個配置文件并添加一個.dll文件，經本人測試，如果完全按照給的說明操作不可行，會出現“報表服務器配置錯誤”，但經過一些列改動之后該方法可行，并且是真正意義上的匿名訪問，將在下文中給出詳細步驟。

涉及到的配置文件如下(目錄視具體安裝情況)：

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：在配置之前先備份以上文件，以防失敗！！！

?

配置過程：

1. ???????? 找到兩個 Web.config 文件中的如下代碼：

< authentication mode = " Windows " />

< identity impersonate = " true " />

替換成：

< authentication mode = " None " />

?< identity impersonate = " false " />

2. ???????? 找到 rsreportserver.config 文件中的如下代碼：

??? < Authentication >

?????? < AuthenticationTypes >

?????????? < RSWindowsNegotiate />

?????????? < RSWindowsNTLM />

?????? </ AuthenticationTypes >

?????? < EnableAuthPersistence > true </ EnableAuthPersistence >

??? </ Authentication >

??? 替換成：

???????? ??? < 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 目錄下（注意：目錄視具體安裝情況而定）

4. ???????? 找到 rsreportserver.config 文件中的如下代碼：

< 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 >

??? 替換成 ：

??? ??????? < 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 中的如下代碼：

</ NamedPermissionSets >

??????????????????? < CodeGroup

??????????????????????????? class = " FirstMatchCodeGroup "

??????????????????????????? version = " 1 "

??????????????????????????? PermissionSetName = " Nothing " >

??????????????????????? < IMembershipCondition

??????????????????????????????? class = " AllMembershipCondition "

??????????????????????????????? version = " 1 "

??????????????????????? />

??? 在后面 添上 如下代碼（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. ???????? 重啟 Reporting Service 服務。
