Question

嗨伙计们。我是c＃的新手，如果这个问题对那里的专家来说听起来很愚蠢，我想道歉。当我尝试在浏览器中的localhost上部署我的mvc应用程序时，我不断收到上述错误。我使用的是IIS服务器。我通过Server exporer连接数据库，系统运行良好。

如果我从Visual Studio运行它，效果很好。当我在浏览器上输入localhost时，我得到应用程序默认登录页面，这很好但是当我提交数据时会出现错误，这使我认为它是数据库连接问题。我已经尝试过对此进行研究，但我还没有找到一个非常适合我的答案。请尽快帮助我，因为我被卡住了。我正在使用Windows身份验证，所以请帮助我，但帮助我使用Windows身份验证连接，并指示我可以更改以确保连接数据库密码和用户身份验证成功后。

提前Thanx！

以下是我的连接字符串

<add name="SA1Entities1" connectionString="metadata=res://*/Models.SA1.csdl|res://*/Models.SA1.ssdl|res://*/Models.SA1.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=NPX4912PLUS;initial catalog=SA1;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

staketrace如下：

Server Error in '/' Application.

好的，这很简单， IS DOCUMENTED 互联网上的很多地方，但我会引导您完成它。

您遇到的基本问题是您正在运行VS，并且您拥有一个SQL Server帐户，因此集成身份验证工作正常，但是IIs不会像您一样运行 - 它作为特殊服务帐户运行而该帐户不会拥有SQL Server的权利。

...所以

从IIs连接到SQL Server时，有两种方法可以执行此操作。

首先，您可以使用集成安全性。如果你这样做，你需要做两件事之一，模仿在你的应用程序源代码中拥有sql server权限的用户，或者设置一个服务帐户作为拥有sql server权限的用户从配置中运行你的网站。非法入境者。如果你进行搜索，这两件事都有很好的记录。
您还可以更改连接字符串以指定用户。这是测试应用程序的最常用方法。有关连接字符串的一些信息，请查看connectionstrings.com。

你去吧。就像我说的那样，简单。：）

回答你的问题是不可能的，因为你提出的问题毫无意义。

你说

如果我从应用程序运行它，效果很好。

什么应用？它是如何工作的，什么效果很好。请解释一下。

当我在浏览器上输入localhost时......

你是什么意思进入localhost？你究竟在做什么请解释一下。

我的默认登录页面很好

这怎么样？什么是默认登录页面？如果您使用集成身份验证，则应该没有登录页面 - 您的意思是您的应用程序的登录页面？如果是这样，我们需要查看该页面的来源。

请尝试解释您正在做的事情，以便我们有机会提供帮助。
