Unity www服务端下载程序

//private string fileName= "file:///"+ @"C:\Users\Administrator\Desktop\LocationSystem.exe";  //本地路径
    private string fileName = "http://127.0.0.1:8013/bin/Exe/LocationSystem.exe";      //服务端路径

上述服务端路径下载文件时，会报错，提示：

             请求筛选模块被配置为拒绝包含hiddenSegment节的URL中的路径。

     解决方案：

             1. 打开  C:\Windows\System32\inetsrv\config\applicationHost.config  删除HiddenSegements中bin节点

              2.找到IIS网站文件夹，把程序从bin目录，移到其他目录下。

private string fileName = "http://127.0.0.1:8013/bin/Exe/LocationSystem.exe";      //原路径

private string fileName = "http://127.0.0.1:8013/Setup/LocationSystem.exe";      //新路径

下面是下载测试代码： 

   之前说下载路径中不能有中文，但是测试时，发现中文也可以下载成功。
