需要修改根目录和admin目录的config.php文件，然后nginx的伪静态设置成如下。
# SEO URL Settings
# Nginx configuration of OC htaccess
location = /sitemap.xml {
rewrite ^(.*)$ /index.php?route=feed/google_sitemap break;
}
location = /googlebase.xml {
rewrite ^(.*)$ /index.php?route=feed/google_base break;
}
location / {
# This try_files directive is used to enable SEO-friendly URLs for OpenCart
try_files $uri $uri/ @opencart;
}
location @opencart {
rewrite ^/(.+)$ /index.php?_route_=$1 last;
}
# End SEO settings
