我在asp.net mvc中创建了一个应用程序。
我正在尝试通过Twitter登录该应用
用户通过Twitter登录后（他/她成功完成），它会点击ExternalLoginConfirmation方法中的后续行
// Get the information about the user from the external login provider
var info = await AuthenticationManager.GetExternalLoginInfoAsync();
执行上述lind后，在浏览器中出现错误
Login failed for user ''.
这就是stacktrace所说的 堆栈跟踪：
[SqlException (0x80131904): Login failed for user ''.]

我猜它无法连接到数据库
我在DAL项目中有dbcontext类
public class TwitterDbContext : IdentityDbContext<User>, ITwitterDbContext
{
public TwitterDbContext()
: base("TwitterContextConnection")
{
}
public static TwitterDbContext Create()
{
return new TwitterDbContext();
}
}
这是我在web.config中的连接字符串
<connectionStrings>
<add name="TwitterContextConnection" connectionString="Data Source=.\SQLEXPRESS;Database=Twitter Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
我已确定SQLEXPRESS正在运行。
我已通过PackageManagerConsole启用了数据库迁移，当我尝试更新数据库时，我也收到错误消息
This operation requires a connection to the 'master' database. Unable to create a connection to the 'master' database because the original database connection has been opened and credentials have been removed from the connection string. Supply an unopened connection.
我做错了吗？数据库还没有存在，但我相信它应该在它不存在时创建。
