Prestashop 1.7.8.6多存储nginx重写规则

Question

我将prestashop 1.7安装为一个多存储区，并将nginx重写规则编写为

location /shop-1/ {
  rewrite ^/shop-1/(.*)$ /$1 last;
  try_files $uri $uri/ /index.php?$args;
}
location /shop-2/ {
  rewrite ^/shop-2/(.*)$ /$1 last;
  try_files $uri $uri/ /index.php?$args;
}

我遵循来自https://devdocs.prestashop.com/1.7/basics/installation/nginx/的nginx文件。

现在，Q是正确导航和显示图像的父域，但多存储重定向到http://example.com/{shop-1或shop-2}，但不显示多个商店url上的图像，在multishop url上得到nginx404错误，而在父域显示相同的图像。

示例：

default/Scrt.jpg没有显示图像

default/Scrt.jpg显示图像

Answer 1

为了解释这里发生了什么，我需要提到nginx 请求处理阶段，这是一个没有多少人真正正确理解的主题。

下面是在NGX_HTTP_SERVER_REWRITE_PHASE上执行的一组重写规则

rewrite ^/(\d)(-[\w-]+)?/.+\.jpg$ /img/p/$1/$1$2.jpg last;
rewrite ^/(\d)(\d)(-[\w-]+)?/.+\.jpg$ /img/p/$1/$2/$1$2$3.jpg last;
rewrite ^/(\d)(\d)(\d)(-[\w-]+)?/.+\.jpg$ /img/p/$1/$2/$3/$1$2$3$4.jpg last;
rewrite ^/(\d)(\d)(\d)(\d)(-[\w-]+)?/.+\.jpg$ /img/p/$1/$2/$3/$4/$1$2$3$4$5.jpg last;
rewrite ^/(\d)(\d)(\d)(\d)(\d)(-[\w-]+)?/.+\.jpg$ /img/p/$1/$2/$3/$4/$5/$1$2$3$4$5$6.jpg last;
rewrite ^/(\d)(\d)(\d)(\d)(\d)(\d)(-[\w-]+)?/.+\.jpg$ /img/p/$1/$2/$3/$4/$5/$6/$1$2$3$4$5$6$7.jpg last;
rewrite ^/(\d)(\d)(\d)(\d)(\d)(\d)(\d)(-[\w-]+)?/.+\.jpg$ /img/p/$1/$2/$3/$4/$5/$6/$7/$1$2$3$4$5$6$7$8.jpg last;
rewrite ^/(\d)(\d)(\d)(\d)(\d)(\d)(\d)(\d)(-[\w-]+)?/.+\.jpg$ /img/p/$1/$2/$3/$4/$5/$6/$7/$8/$1$2$3$4$5$6$7$8$9.jpg last;
rewrite ^/c/([\w.-]+)/.+\.jpg$ /img/c/$1.jpg last;

如您所见，它们都不匹配/shop-1/45-medium_default/skirt.jpg请求URI。因此，在下一轮，在NGX_HTTP_FIND_CONFIG_PHASE期间，您的location /shop-1/ { ... }将被选中来处理请求。接下来，在执行rewrite ^/shop-1/(.*)$ /$1 last;规则之后，您的请求URI将被重写为/45-medium_default/skirt.jpg，并且由于rewrite指令中使用的last标志，NGX_HTTP_FIND_CONFIG_PHASE将再次被执行。但是，不会再次执行NGX_HTTP_SERVER_REWRITE_PHASE，并且不会根据这些规则重写新的URI。您应该做的是将重写规则放在server级别的之前，是重写图像请求的规则集：

rewrite ^/(?:shop-1|shop-2)(/.*) $1;
... image URIs rewrite rules here

请注意，对于此规则，我不使用last (或break)标志，因为在此重写将被触发之后，不应该终止重写规则链。您在问题中所显示的这两个位置都不需要。
