Question

大家好，我正在管理一个用asp.net mvc4编写的网站。但是我对我想要发布的布局和css样式做了一些更改，以便更新当前站点。在发布之前一切正常，当我在发布过程中，我确保我没有触摸web.config文件，我只检查了我想要更新的文件，这主要是一个Html和CSS更改。

发布后我试图登录，我开始收到错误说

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。

当我尝试使用我在localhost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.

在看到您遇到的错误后，问题似乎是在初始化连接之前被调用WebSecurity。

编辑抛出该错误的文件，如下所示：

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

发布网站后出错
