MVC应用程序中的$ .get（）和$ .post（）在本地Cassini网络服务器中可以正常工作，但是当发布到IIS 7.5中后，它将不再起作用
[英]$.get() and $.post() in MVC app works fine in local Cassini webserver but when published into IIS 7.5 it doesn't work anymore
问题描述
I'm actually stuck on this MVC application and can't find out the cause. 
我实际上停留在此MVC应用程序上，无法找到原因。
The code works fine in local Vis Studio 2013 Cassini webserver. 该代码在本地Vis Studio 2013 Cassini Web服务器中运行良好。
Hence when I type the URL in the browser: "/Customer/EnterCustomerDetails" then I'm displayed a simple form, a DIV tag containing status message "Loading..." and after 5 seconds some data via EF is returned due to the $.get() script that gets executed. 因此，当我在浏览器中键入URL：“ / Customer / EnterCustomerDetails”时，将显示一个简单的表单，其中包含状态消息“ Loading ...”的DIV标签，并且在5秒钟后由于EF返回了一些数据。 $ .get（）脚本被执行。
However, when I publish the same code into IIS 7.5 running inside Windows 7 Ultimate, then all I see is the form and only the div tag that displays the message "Loading..." but no data is displayed and it seems the $.get() is not working in the full blown IIS and neither is $.post(). 但是，当我将相同的代码发布到Windows 7 Ultimate中运行的IIS 7.5中时，我看到的只是表单，只有div标签显示消息“ Loading ...”，但没有数据显示，似乎是$。 get（）在完整的IIS中不起作用，$。post（）也不起作用。
Where am I going wrong? 我要去哪里错了？ Any help much appreciated. 任何帮助，不胜感激。 Thanks in advance. 提前致谢。

That sounds like the identity in your IIS app pool is not authorized for database access. 这听起来像您的IIS应用程序池中的身份未获得数据库访问权限。 Either assign a new identity that has permission, or grant access to the identity you are using. 分配具有权限的新身份，或授予对您正在使用的身份的访问权限。
