asp.net-identity – 使用SQL Server而不是LocalDB的Web API和ASP.Net标识

>如何设置ASP.Net Identity以使用SQL Server数据库而不是LocalDB？
>如何自定义ASP.Net Identity以使用自定义数据层？

在Web API .Net 4.5中使用Microsoft.AspNet.Identity.Core 1.0.0和EntityFramework 6.0.0

Web.config更改：

<connectionStrings>
<add name="myAppDB"
     connectionString="data source=.;Initial Catalog=mydb1;Integrated Security=SSPI;"
     providerName="System.Data.SqlClient" />
</connectionStrings>

调用api / account / register时出错

Cannot get a local application data path. Most probably a user profile is not loaded. If LocalDB is executed under IIS,make sure that profile loading is enabled for the current user.

解决方法

如果您使用Web API模板,则默认设置为“无身份验证”,如下图所示.

如果选择“无身份验证”,则不会安装适用于ASP.NET身份的程序集,也不会创建帐户控制器,并且不会使用连接字符串更新web.config.请注意,MVC仍包含在模板中.

如果要使用ASP.NET标识,请选择“更改身份验证”并选择“个人帐户”

现在您拥有了所有必需的程序集,ASP.NET Identity在启动配置中连接,默认连接字符串在您的web.config中.

<configSections>
    <!-- For more information on Entity Framework configuration,visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection,EntityFramework,Version=6.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>
  <connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=  (LocalDb)v11.0;AttachDbFilename=|DataDirectory|aspnet-TestWebApiTemplateWithAuth20140218082219.mdf;Initial Catalog=aspnet-TestWebApiTemplateWithAuth- 20140218082219;Integrated Security=True"
      providerName="System.Data.SqlClient" />
  </connectionStrings>

请注意,您还为Entity Framework配置了并为其配置了正确的程序集.默认情况下,ASP.NET Identity使用EF代码优先于数据存储.默认设置为使用本地数据库.只需更改此连接字符串即可使用SQL Server数据库.

如果要将基础数据存储更改为SQL Server以外的其他数据,则存在a tutorial you can follow here.此特定教程显示如何将其更改为MySql.
