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!
