大卫的解决办法很好。但是我发现页面中的<script>警报(document.domain);</script>仍然警告“localhost”，因为项目Url仍然是localhost，即使它已经被http://dev.example.com覆盖。我遇到的另一个问题是，它提醒我端口80已经在使用，即使我已经禁用Skype使用80端口号，由大卫默多克推荐。所以我想出了另一个更简单的解决方案:

Run Notepad as administrator, and open the C:\Windows\System32\drivers\etc\hosts, add 127.0.0.1 mydomain, and save the file; Open the web project with Visual Studio 2013 (Note: must also run as administrator), right-click the project -> Properties -> Web, (lets suppose the Project Url under the "IIS Express" option is http://localhost:33333/), then change it from http://localhost:33333/ to http://mydomain:333333/ Note: After this change, you should neither click the "Create Virtual Directory" button on the right of the Project Url box nor click the Save button of the Visual Studio as they won't be succeeded. You can save your settings after next step 3. Open %USERPROFILE%\My Documents\IISExpress\config\applicationhost.config, search for "33333:localhost", then update it to "33333:mydomain" and save the file. Save your setting as mentioned in step 2. Right click a web page in your visual studio, and click "View in Browser". Now the page will be opened under http://mydomain:333333/, and <script>alert(document.domain);</script> in the page will alert "mydomain".

注意:上面列出的端口号假设为33333。您需要将其更改为您的visual studio设置的端口号。

Post编辑:今天我尝试了另一个域名，得到以下错误:无法启动IIS Express Web服务器。注册URL失败…访问被拒绝。(0 x80070005)。我通过右键单击Windows任务栏右下角的IIS Express图标退出IIS Express，然后以管理员身份重新启动我的visual studio，问题就解决了。

以防万一有人需要…

我的要求是:

启用SSL 自定义的域 运行在(默认)端口:443

在IISExpress中设置这个URL: http://my.customdomain.com

为了设置这个，我使用了以下设置:

项目网址:http://localhost:57400

起始URL: http://my.customdomain.com

/ .vs / {solution-name} / config / applicationhost。配置设置:

<site ...>
    <application>
        ...
    </application>
    <bindings>
        <binding protocol="http" bindingInformation="*:57400:" />
        <binding protocol="https" bindingInformation="*:443:my.customdomain.com" />
    </bindings>
</site>

在我的WebMatrix IIS Express安装中，从“*:80:localhost”更改为“*:80:custom”。hostname“没有工作(“坏的主机名”，即使有适当的etc\hosts映射)，但“*:80:”工作-并且没有其他答案所要求的额外步骤。注意，“*:80:*”不会这样做;去掉第二个星号。

无效的主机名表明您在IIS Express配置文件中配置的实际站点(很可能)未运行。IIS Express没有IIS那样的流程模型。

要运行站点，需要显式启动(通过从webmatrix打开并访问，或者通过命令行调用iisexpress.exe(从它的安装目录)，并使用/site参数。

通常，允许使用完全限定的DNS名称进行本地访问的步骤如下 让我们使用DNS名称dev.example.com的示例

edit %windows%\system32\drivers\etc\hosts file to map dev.example.com to 127.0.0.1 (admin privilege required). If you control DNS server (like in Nick's case) then the DNS entry is sufficient as this step is not needed. If you access internet through proxy, make sure the dev.example.com will not be forwared to proxy (you have to put in on the exception list in your browser (for IE it would be Tools/Internet Options/Connections/Lan Settings, then go to Proxy Server/Advanced and put dev.example.com on the exeption list. Configure IIS Express binding for your site (eg:Site1) to include dev.example.com. Administrative privilege will be needed to use the binding. Alternatively, a one-time URL reservation can be made with http.sys using netsh http add urlacl url=http://dev.example.com:<port>/ user=<user_name> start iisexpress /site:Site1 or open Site1 in WebMatrix

把这个留在这里，以防有人需要…

我需要在IIS Express中为Wordpress Multisite设置自定义域，但在我以管理员身份运行Webmatrix/Visual Studio之前，任何东西都不起作用。然后我就可以将子域绑定到同一个应用程序。

<bindings> 
    <binding protocol="http" bindingInformation="*:12345:localhost" />
    <binding protocol="http" bindingInformation="*:12345:whatever.localhost" />
</bindings>

然后转到http://whatever.localhost:12345/将运行。
