默认情况下，IIS中HTTPS 绑定是无法指定主机名的
解决办法：通过手工修改 IIS 配置来实现主机头绑定。打开如下位置的文件。

C:\Windows\system32\inetsrv\config\applicationHost.config

找到节点

<bindings> <binding protocol="net.tcp" bindingInformation="808:*" /> <binding protocol="net.pipe" bindingInformation="*" /> <binding protocol="net.msmq" bindingInformation="localhost" /> <binding protocol="msmq.formatname" bindingInformation="localhost" /> <binding protocol="http" bindingInformation="*:80:www.xxxxxx.com" /> <binding protocol="https" bindingInformation="*:443:" /></bindings>

更改为你的域名

<binding protocol="https" bindingInformation="*:443:www.xxxxxx.com" />

ok!
