Question

我实际上已经停留在这个MVC应用程序上，无法找出原因。

该代码在本地Vis Studio 2013 Cassini网络服务器中运行良好。

因此，当我在浏览器中键入URL时：“/ Customer / EnterCustomerDetails” 然后我显示了一个简单的表单，一个包含状态消息“Loading ...”的DIV标签，5秒后，由于执行了$ .get（）脚本，返回了一些通过EF的数据。

然而，当我将相同的代码发布到在Windows 7 Ultimate中运行的IIS 7.5中时，我所看到的只是表单，只有div标签显示消息“正在加载...”但没有显示数据，似乎$ .get（）不能在完整的IIS中运行，也不是$ .post（）。

我哪里错了？任何帮助非常感谢。提前谢谢。

将此作为答案发布，以便您将其标记为已接听。

这听起来像您的IIS应用程序池中的标识未被授权进行数据库访问。分配具有权限的新标识，或授予对您正在使用的标识的访问权限。

MVC应用程序中的$ .get（）和$ .post（）在本地Cassini网络服务器中运行良好，但在发布到IIS 7.5后，它不再起作用
