【问题描述】:

嘿,我有大约 5k~ 的网址要重定向。我正在尝试应用此 stackoverflow post 中定义的逻辑 ,但是,我在测试配置文件后出现错误;

2019/10/07 10:08:33 [emerg] 386#386: unknown "old_uri" variable
nginx: [emerg] unknown "old_uri" variable
nginx: configuration file /etc/nginx/nginx.conf test failed

这是我正在处理的 hello-world nginx 示例中非常基​​本的文件。

/etc/nginx/conf.d/default.conf

include /etc/nginx/conf.d/redirects.map;

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;
    if ($new_uri) {
    rewrite ^ $new_uri permanent;
    }

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

redirects.map

map $old_uri $new_uri {
    default "";
    /about.html /about-us;
    /careers.html /awesome-careers;
}

/etc/nginx/nginx.conf


user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


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

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*;
}

感谢您的帮助!非常感谢

【问题讨论】:

  • 没有名为$old_uri 的变量。你的意思是$request_uri
  • 大声笑我以为我们定义了 url,nginx 只是解决了它们。非常感谢@RichardSmith,它起作用了。您能否添加一个答案,以便我接受。

标签: nginx nginx-config


【解决方案1】:

在您的map 中,变量$old_uri 不存在,您应该改用$request_uri$uri。请参阅this answer 了解区别。

if 块中,如果您希望将原始查询字符串附加到新 URI,请使用您的 rewrite 语句。

否则,如果您想丢弃原始查询字符串,请使用return 301 $new_uri;

【讨论】:

  • 非常感谢!所有的 url 实际上都是静态 url,没有任何查询参数。那么,在这种情况下,我应该使用return 301 $new_uri; 对吗?
  • rewrite 语句会起作用,但过于矫枉过正。 return 语句效率更高。
