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：
正则表达式位置在正则表达式模式中没有锚点 正则表达式位置的正则表达式模式中没有 ^ 或 $。这种配置样式容易出错。还可能导致部分匹配正则表达式模式的请求被错误地路由到此位置。在正则表达式模式中始终使用 ^ 或 $ 锚点。
检查以下文件：/etc/nginx/conf.d/01-mail.example.com，第 27 行 /etc/nginx/conf.d/01-mail.example.com，第 89 行 /etc/nginx/sites-enabled/03-example2.com.conf，第 176 行 /etc/nginx/sites-enabled/03-example2.com.conf，第 199 行 /etc/nginx/sites-enabled/03-example2.com.conf，第 265 行
