如何從http重定向到https

Question

如何從http重定向到https：

1. redirect http://example.com to https://www.example.com
2. redirect http://www.example.com to https://www.example.com
3. redirect https://example.com to https://www.example.com

像Facebook，谷歌？

請使用.htaccess或其他代碼幫助我。

Answer 1

要在單個規則中處理所有這3個重定向，您可以在DOCUMENT_ROOT/.htaccess文件中使用以下代碼：

RewriteEngine On

RewriteCond %{HTTP:CF-Visitor} '"scheme":"http"' [OR]
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^ https://www.example.com%{REQUEST_URI} [NE,R=301,L]

RewriteCond %{HTTP:CF-Visitor} '"scheme":"http"'
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [NE,R=301,L]

Answer 2

只需將以下內容添加到您的.htaccess中

RewriteEngine On
RewriteCond %{HTTPS} !on
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

Answer 3

RewriteEngine On
# ensure www.
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https 
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
