ASP.NET MVC验证错误：需要<field>字段

Question

我有一个使用Visual Studio 2015创建的ASP.Net MVC项目。我正在使用默认的vs2015身份验证实现。该项目使用IIS Express在本地调试模式下正常工作，但在使用IIS将项目部署到服务器后，MVC验证无法正常工作。例如，当我提交登录表单：正如你所看到的形式充满了数据，如果需要的一个不为空（

：

我得到这个错误表单域是空的，表单永远不会提交）。

这与JavaScript无关。我禁用了js并重新提交了表单并得到了相同的错误。我错过了什么？

Answer 1

修改你的系统的网络是这样的：

<system.web> <customErrors mode="Off"/> <authentication mode="None"/> <compilation debug="false" targetFramework="4.5.2"/> </system.web>

它应该帮助你的网络配置属性的（休息不是为了清晰起见而添加的）
