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

Question

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

This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct.","ExceptionType":"System.Data.Entity.Core.ProviderIncompatibleException","StackTrace":"   at System.Web.Http.ApiController.<InvokeActionWithExceptionFilters>d__1.MoveNext()

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.

如果您尚未更改 MVC 5 Internet 模板使用的基本配置，则 ASP.NET 标识的连接字符串的名称为“DefaultConnection”。尝试使用此名称创建连接字符串并将其配置为指向 sql server。

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 ASP.NET 标识的相应程序集，不会创建帐户 Controller ，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 Identity，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 连接在启动配置中，默认连接字符串位于您的 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，您还针对 Entity Framework 进行了配置，并为此拥有正确的程序集。默认情况下，ASP.NET Identity 对数据存储使用 EF 代码优先。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。

如果您想将基础数据存储更改为 SQL Server 以外的其他内容，则可以使用 a tutorial you can follow here .这个特定的教程展示了如何将其更改为 MySql。
