Nginx gzip 压缩不适用于 css 或 js

Question

gzip 压缩适用于 html 页面，但不适用于 css 或 js，我发现了几个类似的问题，包括以下内容，并尝试了建议的解决方案，我试过了(gzip_buffers、gzip_min_length、gzip_comp_level) 的各种设置，但 none 有效。

还有什么可能影响这个，为什么 js 或 css 文件没有压缩？

我在 nginx conf 中有以下 http 块：

http {

    upstream fastcgi_backend {
            server 127.0.0.1:9000;
    }

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    access_log off;

    #access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    # Enable Gzip compression
    gzip          on;

    gzip_vary on;
    gzip_buffers 128 4k;

    # Compression level (1-9)
    gzip_comp_level     5;

    # Don't compress anything under 256 bytes
    gzip_min_length     256;

    # Compress output of these MIME-types
    gzip_types
        application/atom+xml
        application/javascript
        application/json
        application/rss+xml
        application/vnd.ms-fontobject
        application/x-font-ttf
        application/x-font-opentype
        application/x-font-truetype
        application/x-javascript
        application/x-web-app-manifest+json
        application/xhtml+xml
        application/xml
        font/eot
        font/opentype
        font/otf
        image/svg+xml
        image/x-icon
        image/vnd.microsoft.icon
        text/css
        text/plain
        text/javascript
        text/x-component;

    # Disable gzip for bad browsers
    gzip_disable  "MSIE [1-6]\.(?!.*SV1)";

    # allow the server to close connection on non responding client, this will free up memory
    reset_timedout_connection on;

    # request timed out -- default 60
    client_body_timeout 10;
}

检查 conf.d 文件夹中是否有其他可能覆盖 nginx.conf 的 conf 文件，您应该会看到至少一个包含 hostname/IP Nginx 正在服务的服务器块的文件。看起来像这样：

server {
    listen 80;
    listen [::]:80;
    server_name example.com;

    return 301 https://example.com$request_uri;
}

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name example.com;

    ...
}

您可以随时搜索服务器块：$ grep -rl "server_name" /etc/nginx
