IIS7.0(虚拟机)发布MVC5程序出现Http403错误的解决方法.

　　近来,用MVC5开发自己的一个小网站.网上租用了一个小空间(虚拟主机),可选.net版本为2.0 3.0 3.5 4.0 ,上传网站 后发现是403错误.不能访问.

经与技术人员联系,把虚拟机更换到高版本.net4.5.1上面,还是不行.在本地IIS环境下可以访问.远程服务器下不能访问.

多方查资料未能解决.服务器提供方也无能为力了.只能自己再想办法解决.原来在刚刚购买空间时上传了一个.net2.0的程序,能正常运行.而且服务器上以经安装了相应.net框架,理论上是应该能使用的.本着解决问题不怕麻烦的精神,用VS2013建立了多个版本的网站基本程序,(如: .net4.0 MVC4, .net4.5 MVC4, .net4.5 Mvc5,.net4.5.1 MVC5)发现在.net4.0 MVC4,能够访问,其它的三个都不能访问.遂对比Web.config文件.

这是.net4.5.1 MVC5 的Web.config代码

仔细观察发现,在
  <appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
    <add key="webpages:Enabled" value="false" />
       <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
  </appSettings>

中间少一条 <add key="PreserveLoginUrl" value="true" /> 这个应该是登录引导用的.应该用处不大.

最主要的是在  <system.webServer>   </system.webServer>  看了网上好多方法,都是在这里面加上<modules runAllManagedModulesForAllRequests="true" />   ,这个我试了,不管用,反而会引发500错误.经过对比,发现需要加入以下代码

  <system.webServer>

    <validation validateIntegratedModeConfiguration="false" />

    <modules runAllManagedModulesForAllRequests="true" />

  <handlers>
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />

    </handlers>

  </system.webServer>

用这段代码替换你的Config文件相应的配置节

当然了,你的配置节里有其它配置,就要自己有选择的添加了.

经测试,成功!!!!现记录下来,一来备忘,二来可以帮助有需要的人.
