我很困惑并关注以下行,因为OAuthWebSecurity的API似乎有自己的身份验证存储。
// If the current user is logged in add the new account
OAuthWebSecurity.CreateOrUpdateAccount(result.Provider, result.ProviderUserId, User.Identity.Name);
如果我正确阅读上述内容,似乎表明API在本地保存了关系。
请告诉我情况并非如此,并解释它究竟是做什么的?我需要我的Web应用程序尽可能无状态,我不能让API存储像这样的本地值。

它使用作为ASP.NET MVC 4中的默认提供程序的SimpleMembershipProvider
来创建或更新公共提供程序用户标识与本地用户之间的关联。基本上它会在webpages_OAuthMembership
表中添加记录。
以下是来自WebSecurity.CreateOrUpdateOAuthAccount
的相应代码:
public override void CreateOrUpdateOAuthAccount(string provider, string providerUserId, string userName)
{
this.VerifyInitialized();
if (userName.IsEmpty())
{
throw new MembershipCreateUserException(MembershipCreateStatus.ProviderError);
}
int userId = this.GetUserId(userName);
if (userId == -1)
{
throw new MembershipCreateUserException(MembershipCreateStatus.InvalidUserName);
}
int userIdFromOAuth = this.GetUserIdFromOAuth(provider, providerUserId);
using (IDatabase database = this.ConnectToDatabase())
{
if (userIdFromOAuth == -1)
{
if (database.Execute("INSERT INTO [" + OAuthMembershipTableName + "] (Provider, ProviderUserId, UserId) VALUES (@0, @1, @2)", new object[] { provider, providerUserId, userId }) != 1)
{
throw new MembershipCreateUserException(MembershipCreateStatus.ProviderError);
}
}
else if (database.Execute("UPDATE [" + OAuthMembershipTableName + "] SET UserId = @2 WHERE UPPER(Provider)=@0 AND UPPER(ProviderUserId)=@1", new object[] { provider, providerUserId, userId }) != 1)
{
throw new MembershipCreateUserException(MembershipCreateStatus.ProviderError);
}
}
}
