可直接修改web.config。IIS控制台右键单击需要设置的站点，选择“浏览”，编辑Web.config文件。在system.webServer之间添加以下内容:

web.config<configuration> <system.webServer> <rewrite> <rules> <rule name="HTTP to HTTPS redirect" stopProcessing="true"> <match url="(.*)" /> <conditions> <add input="{HTTPS}" pattern="off" ignoreCase="true" /> </conditions> <action type="Redirect" redirectType="Found" url="https://{HTTP_HOST}/{R:1}" /> </rule> </rules> </rewrite> </system.webServer></configuration>
