关于Membership的设置
初学MemberShip,遇到一个Membership设置的问题因为一般教程使用的示例都是SQL Server 2005 Express版本的本地 ASPNETDB.MDF文件,如果我要使用远程的Sql Server 2005服务器的话,需要进行一些设置。
Setp1:当你使用Membership, 我们可以发现ASP.NET 2.0 已经在 SQL Server 2005 Express建立了很多表(aspnet_Membership等),视图,存储过程等。当时我们自己的远程服务器上并没有这些表。难道我们需要自己建?当然不用,微软给我们准备了一个工具:

目录下的aspnet_regsql工具根据它的向导,可以很方便地指定你的服务器和数据库。完成之后,我们可以发现,我们的远程服务器上制定数据库上已经创建好了我们需要的表,视图,存储过程等。
Step2:这时候我们需要在web.config更改Membership的Provider
我们可以参考machine.config文件中的内容:(machine.config在%systemroot%\Microsoft.NET\Framework\v2.x\CONFIG目录下)
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> < connectionStrings > < add name ="LocalSqlServer" connectionString ="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName ="System.Data.SqlClient" /> </ connectionStrings > < membership > < providers > < add name ="AspNetSqlMembershipProvider" type ="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName ="LocalSqlServer" enablePasswordRetrieval ="false" enablePasswordReset ="true" requiresQuestionAndAnswer ="true" applicationName ="/" requiresUniqueEmail ="false" passwordFormat ="Hashed" maxInvalidPasswordAttempts ="5" minRequiredPasswordLength ="7" minRequiredNonalphanumericCharacters ="1" passwordAttemptWindow ="10" passwordStrengthRegularExpression ="" /> </ providers > </ membership >
你可以直接在machine.config里更改,不过这里一更改,会影响到以后所有ASP.NET程序的设置,所以我们还是在自己的web.config中更改比较好.在web.config中,首先创建我们自己的连接字符串:
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> < connectionStrings > < add name ="remoteSqlServer" connectionString ="server=..;uid=..;pwd=..;initial catalog=.." providerName ="System.Data.SqlClient" /> </ connectionStrings >
然后修改Membership的provider.,修改的时候需要注意一个问题,因为machine.config中已经存在一个provider了,所以你直接增加一个provider的话
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> < membership > < providers > < add name ="RemoteSqlMembershipProvider" type ="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName ="remoteSqlServer" enablePasswordRetrieval ="false" enablePasswordReset ="true" requiresQuestionAndAnswer ="false" applicationName ="/" requiresUniqueEmail ="false" passwordFormat ="Hashed" maxInvalidPasswordAttempts ="5" minRequiredPasswordLength ="7" minRequiredNonalphanumericCharacters ="1" passwordAttemptWindow ="10" passwordStrengthRegularExpression ="" /> </ providers > </ membership >
在程序运行中还是会去寻找在machineconfig中定义的AspNetSqlMembershipProvider,因为那个是default的。所以一种选择是,我们把这个新的Provider设置为Default的。
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> < membership defaultProvider ="RemoteSqlMembershipProvider" > < providers > < add name ="RemoteSqlMembershipProvider" type ="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName ="remoteSqlServer" enablePasswordRetrieval ="false" enablePasswordReset ="true" requiresQuestionAndAnswer ="false" applicationName ="/" requiresUniqueEmail ="false" passwordFormat ="Hashed" maxInvalidPasswordAttempts ="5" minRequiredPasswordLength ="7" minRequiredNonalphanumericCharacters ="1" passwordAttemptWindow ="10" passwordStrengthRegularExpression ="" /> </ providers >
另一种选择是,我们首先clear原来的provider,然后再增加自己的provider(connectiongStringName设置为我们自己的ConnectionString):
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> < membership > < providers > < clear /> < add name ="AspNetSqlMembershipProvider" type ="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName ="remoteSqlServer" enablePasswordRetrieval ="false" enablePasswordReset ="true" requiresQuestionAndAnswer ="false" applicationName ="/" requiresUniqueEmail ="false" passwordFormat ="Hashed" maxInvalidPasswordAttempts ="5" minRequiredPasswordLength ="7" minRequiredNonalphanumericCharacters ="1" passwordAttemptWindow ="10" passwordStrengthRegularExpression ="" /> </ providers > </ membership >
这里需要注意的另一个问题就是,provider的名字一定需要是AspNetSqlMembershipProvider,其他名字就会出现这个错误:Default Membership Provider could not be found.因为原来已经指定了AspNetSqlMembershipProvider为Default Provider.
