我正在使用 Nginx Amplify 运行 Nginx。在我的 Amplify>Analyzer>Static Analysis 部分中，我收到以下错误：
Regex location has no regex pattern
Regex location has a valid modifier, but does not have a regex pattern.
Performance-wise it is more efficient to configure exact or prefix matching for locations that do not require regex matching. It is also less prone to errors. Please refer to the documentation describing location directive to learn more.
Check the following files:
/etc/nginx/conf.d/mail.example.com.conf, line 27
/etc/nginx/conf.d/mail.example.com.conf, line 89
/etc/nginx/sites-enabled/03-example2.com.conf, line 176
/etc/nginx/sites-enabled/03-example2.com.conf, line 265
我的“ mail.example.conf”虚拟主机如下所示：

在此文件中，Amplify 似乎正在谈论这些行：
location ~ /\.well-known {
和
location ~ /\. {
在这两个文件中，我应该在相应的行中查找和替换什么才能满足 Amplify 的建议？
答案1
这些不是错误 - 而是警告。Nginx 和 ACME 仍可正常工作。要让您的网站运行得更快、消耗更少的 CPU 并消除警告，只需将正则表达式更改为文字前缀：
更改：（
location ~ /.well-known/acme-challenge {这是*写得很糟糕的正则表达式）至location /.well-known/acme-challenge {（即删除~和任何正则表达式转义）等。
