发布网站后发生错误

Question

大家好，我正在管理一个用asp.net mvc4写的网站。但是，我对布局和css样式做了一些更改，我想发布这些样式，以便更新当前的站点。在发布之前，一切都进行得很好，在发布过程中，我确保没有接触到web.config文件，我只检查了想要更新的文件，这主要是Html和css的更改。

在发布和尝试登录之后，我开始收到一个错误信息

Error
An error occurred while processing your request.

请帮帮我。我可以提供任何其他信息，可以帮助我解决这个问题。

当我尝试本地主机上的那个时，我得到了这个错误。

You must call the "WebSecurity.InitializeDatabaseConnection" method before you call any other method of the "WebSecurity" class. This call should be placed in an _AppStart.cshtml file in the root of your site.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.InvalidOperationException: You must call the "WebSecurity.InitializeDatabaseConnection" method before you call any other method of the "WebSecurity" class. This call should be placed in an _AppStart.cshtml file in the root of your site.

Answer 1

在看到所得到的错误后，问题似乎是在初始化连接之前调用了WebSecurity。

编辑引发该错误的文件，如下所示：

public ActionResult Login(LoginModel model, string returnUrl)
{
    if (!WebSecurity.Initialized)
    {
        WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);
    }
