為特定 url 啟用 nginx 瀏覽器記憶體

如何為特定 URL 啟用 nginx 記憶體？我有一個 django web 應用程序，我將我的靜態文件（如 CSS、JavaScript 和 …）放在一個名為 static 的文件夾中，我可以通過http://example.com/static/訪問它們，我想配置 nginx n僅從此 url 擷取這些文件。我已經閱讀了http://www.nginxtips.com/how-to-enable-browser-cache-static-files-on-nginx/但是這裡沒有解釋這個選項。我嘗試了以下配置並重新啟動了我的 nginx 伺服器，但出現了錯誤。這是我的 sites-available/default配置文件。有什麼問題？

server {
       listen  80;
       listen  443 ssl;
       server_name     www.example.com example.com;
       ssl_certificate /var/www/example/ssl/ssl.crt;
       ssl_certificate_key     /var/www/example/ssl/ssl.key;
       location /static (jpg|jpeg|png|gif|ico|css|js)$ {
               alias   /var/www/example/static;
               expires 3d;
               add_header Pragma public;
               add_header Cache-Control "public, must-revalidate, proxy-revalidate";

       }
       location /media  {
               alias  /var/www/example/media;
       }
       location / {
               proxy_pass      http://127.0.0.1:8000;
       }
}

這是 nginx 日誌文件內容…

從nginx wiki看來，您在“/static”和您的正則表達式模式之間有一個空格。Location 只接受一個“uri”參數，而不是兩個……並且 nginx 會將該空間解釋為參數分隔符。

此外，您還需要告訴位置塊您想將正則表達式與“~”或“~*”修飾符匹配。

你可以試試這個

location ~* "/static.*(jpg|jpeg|png|gif|ico|css|js)$" {

而不是你所擁有的，看看它是否符合你的要求。

您在此文件夾中還有其他文件嗎？如果你沒有，或者如果可以讓它們暴露，你可以簡化配置：

server {
       listen  80;
       listen  443 ssl;
       server_name     www.example.com example.com;
       ssl_certificate /var/www/example/ssl/ssl.crt;
       ssl_certificate_key     /var/www/example/ssl/ssl.key;
       root /var/www/example;

       location / {
               proxy_pass      http://127.0.0.1:8000;
       }

       location /media/ {
               # it's ok to have empty location
       }

       location /static/ {
               expires 3d;
               add_header Pragma public;
               add_header Cache-Control "public, must-revalidate, proxy-revalidate";
       }
}
