为 Laravel 有条件地使用 nginx 服务 WEBP

  • 772

我无法在我的 Ubuntu 服务器上向 webp 提供 jpeg 或 png 图像。

请求：

Request URL: https://staging.myserver.com/images/mainfoto.jpg 
Request Method: GET

回应是：

accept-ranges: bytes
content-length: 304152
content-type: image/jpeg
date: Mon, 07 Oct 2019 17:33:14 GMT
etag: "5d9a2b60-4a418"
last-modified: Sun, 06 Oct 2019 17:58:56 GMT
server: nginx/1.14.0 (Ubuntu)
status: 200
vary: Accept

在sudo nano /etc/nginx/nginx.conf

http {
...
include /etc/nginx/mime.types; #I checked the webp is included
...
    map $http_accept $webp_suffix {
       default "";
       "~*webp" ".webp";
    }
...
}

然后在我的sudo nano /etc/nginx/sites-available/staging.myserver.com

# Checking if there's a WebP version for the requested image ..
location ~* ^.+\.(jpe?g|png)$ {
   add_header Vary Accept;
   # and if so, serving it
   try_files $1$webp_suffix $uri =404;
}

并完成：

sudo nginx -t
sudo systemctl reload nginx

并通过硬重新加载删除了浏览器缓存

有什么想法我能做什么？

完整的服务器配置文件在这里：

    server_name staging.myserver.com;
    root /var/www/myserver-staging/current/public;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options "nosniff";

    index index.html index.htm index.php;

    charset utf-8;

    location / {
        try_files $uri $uri/ /index.php?$query_string;

        auth_basic "Staff Only";
        auth_basic_user_file "/var/www/myserver/.htpasswd";
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    error_page 404 /index.php;

    location ~ \.php$ {

    }
    # Checking if there's a WebP version for the requested image ..
    location ~* ^.+\.(jpe?g|png)$ {
       add_header Vary Accept;
       # and if so, serving it
       try_files $1$webp_suffix $uri =404;
    }
    location ~ /\.(?!well-known).* {
        deny all;
    }
   listen 443 ssl; # managed by Certbot

}
server {
    if ($host = staging.myserver.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    server_name staging.myserver.com;



    listen 80;
    return 404; # managed by Certbot


}

    根据您问题下方的评论，最初的问题是您的代码捕获了请求图像的文件扩展名，并搜索了一个文件名由文件扩展名和尾随 webp 后缀组成的文件，例如jpg.webp.

    --

    关于如何服务image.webp或image.jpg等：

    填充所需的变量：

    # Check if client is capable of handling webp
map $http_accept $webp_suffix {
       default "";
       "~*webp" ".webp";
}

# Capture image path, without the file extension
map $uri $image {
       ~*^/(images)/(.+)\.(jpe?g|png)$  /$1/$2;
}

    ...并在以下位置使用它们：

    location /images {
       add_header Vary Accept;
       try_files $image$webp_suffix $uri =404;
}
