https 上的非 www 到 www

Question

我在将 http 重定向到 https 时遇到了一些问题。朋友帮我找到了解决办法，但还是有些麻烦。

RewriteEngine On 
RewriteCond %{SERVER_PORT} 80
RewriteCond %{HTTP_HOST} ^(www\.)?thevideocards\.com
RewriteRule ^(.*)$ https://www.thevideocards.com/$1 [R,L]

这会将 http 重定向到 https，将 http 重定向到 https://www，但不会将 https://example 重定向到 https://www.example。有人知道应该改变什么来强制所有流量到https://www.example.com 吗？

了解您正在编写的代码的含义很重要 - 否则，谁知道有人在说服您添加什么后门。

让我们分解一下你所拥有的：

# Turn on Apache's "Rewrite Engine"; this is the module that processes the next few lines
RewriteEngine On 

# Condition (for following rule): match only if the connection is on port 80
# Port 80 is (by convention) used for plain-text HTTP traffic
# An alternative to this would be to check for a secure connection directly:
# RewriteCond %{HTTPS} !on
RewriteCond %{SERVER_PORT} 80

# Condition (for following rule): match only if the HTTP Host header matches a regex
# The (www\.)? means that prefix is optional, 
#  so it will match both www.thevideocards.com and thevideocards.com
RewriteCond %{HTTP_HOST} ^(www\.)?thevideocards\.com

# Rule (if the above two conditions also match):
# ^(.*)$ - Match any URL, and capture as $1
# https://www.thevideocards.com/$1 - Generate the replacement URL based on the captured part
# [R] - Send redirect response to browser, rather than processing internally
# [L] - Don't process any more rewrite rules for this request
RewriteRule ^(.*)$ https://www.thevideocards.com/$1 [R,L]

根据以上内容，您应该能够为您想要的情况创建自己的规则：

• 条件：主机匹配没有www.
• 规则：将所有内容重定向到前面带有https://www. 的相同URL

（或者，花 10 分钟搜索，您可能会发现大约一百万页谈论如何做到这一点；但同样，如果您不知道他们做什么，您怎么知道该信任哪一个？）
