Unity 打包发布到 Web 相关配置

1. IIS 发布时，web.config 配置文件如下所示：
   

   <?xml version="1.0" encoding="UTF-8"?>
   <configuration>
       <system.webServer>
           <staticContent>
               <mimeMap fileExtension=".data" mimeType="multipart/form-data" />
               <mimeMap fileExtension=".unity3d" mimeType="application/octet-stream" />            
               <mimeMap fileExtension=".unityweb" mimeType="application/binary" />
           </staticContent>
           <httpProtocol>
               <customHeaders>
                   <add name="Access-Control-Allow-Origin" value="*" />
                   <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
                   <add name="Access-Control-Allow-Headers" value="Content-Type" />
               </customHeaders>
           </httpProtocol>
       </system.webServer>
   </configuration>
