配置好了https站点后，还需要设置301跳转，http站点跳转到https站点。先下载安装URL重写模块：Microsoft URL Rewrite Module
32位URL重写模块下载：/download/4/9/C/49CD28DB-4AA6-4A51-9437-AA001221F606/rewrite_x86_zh-CN.msi
64位URL重写模块：/download/4/E/7/4E7ECE9A-DF55-4F90-A354-B497072BDE0A/rewrite_x64_zh-CN.msi
下载对应的文件在服务器上安装好后，新建web.config文件，内容如下
<?xml version="1.0" encoding="UTF-8"?><configuration><system.webServer><rewrite><rules><rule name="HTTP to HTTPS redirect" stopProcessing="true"><match url="(.*)" /><conditions><add input="{HTTPS}" pattern="^OFF$" /></conditions><action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent" /></rule></rules></rewrite></system.webServer></configuration>
将web.config放在网站根目录后，重启IIS即可
