nginx 转发 20%（空格）而不是 URL 中的 +

nginx 转发 20%（空格）而不是 URL 中的 +

我有一个 NGINX 配置，它使用正则表达式转换 URL，这很好用。问题是，在转发到新的 Atlassian 实例时，URL 中的 + 会变成 %20，这在应用程序中本身是有意义的。

user nginx;
worker_processes auto;
worker_rlimit_nofile 8192;
pid /run/nginx/nginx.pid;

events {
worker_connections 4000;
}

error_log /var/log/nginx/error.log error;

http {



server {
    listen 443  ssl default_server;
    server_name localhost;
    ssl_certificate /etc/nginx/certs/REDACTED.cert;
    ssl_certificate_key /etc/nginx/certs/REDACTED.key;
    location / {
        set $unencoded_args on;
        set $substitute_url '';

        if ($request_uri ~* "https:\/\/(confluence|public)\.REDACTED\.nl\/display\/(.*)\/(.*)") {
            set $unencoded_arg_substitute_url 'https://REDACTED.atlassian.net/wiki/pages/viewpage.action?spaceKey=$2&title=$3';
            rewrite ^ $unencoded_arg_substitute_url redirect;
        }

        if ($request_uri ~* "https:\/\/(confluence|public)\.REDACTED\.nl\/pages\/viewpage.action\?spaceKey=(.*)&title=(.*)") {
            set $unencoded_arg_substitute_url 'https://REDACTED.atlassian.net/wiki/pages/viewpage.action?spaceKey=$2&title=$3';
            set $substitute_url  $unencoded_arg_substitute_url;
            rewrite ^ $substitute_url permanent;
        }

        if ($request_uri ~* "https:\/\/confluence\.REDACTED\.nl\/pages\/viewpage.action\?pageId=(.*)") {
            set $unencoded_arg_substitute_url 'https://REDACTED.atlassian.net/l/cp/VjEHCLZv';
            rewrite ^ $unencoded_arg_substitute_url redirect;
            proxy_pass $unencoded_arg_substitute_url;
        }

        if ($substitute_url = '') {
            set $unencoded_arg_substitute_url 'https://REDACTED.atlassian.net/wiki';
            rewrite ^ $unencoded_arg_substitute_url redirect;
        }


        proxy_pass $unencoded_arg_substitute_url;
        proxy_set_header Host REDACTED.atlassian.net/wiki;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_next_upstream error timeout http_500 http_502 http_503 http_504;
        root /var/www;
        index index.html;
        error_page 502 503 504 fallback.html;
        error_page 404  not_found.html;
        error_page 401 unauthorized.html;
        
    }
}
}

这是我目前的代码

要保留 URL 中的 + 字符，可以使用带有 break 标志的重写指令。以下是修改配置以执行此操作的方法：

    server {
    listen 443 ssl default_server;
    server_name localhost;
    ssl_certificate /etc/nginx/certs/REDACTED.cert;
    ssl_certificate_key /etc/nginx/certs/REDACTED.key;

    location / {
        set $unencoded_args on;
        set $substitute_url '';

        if ($request_uri ~* "https:\/\/(confluence|public)\.REDACTED\.nl\/display\/(.*)\/(.*)") {
            set $unencoded_arg_substitute_url 'https://REDACTED.atlassian.net/wiki/pages/viewpage.action?spaceKey=$2&title=$3';
            rewrite ^ $unencoded_arg_substitute_url redirect;
        }

        if ($request_uri ~* "https:\/\/(confluence|public)\.REDACTED\.nl\/pages\/viewpage.action\?spaceKey=(.*)&title=(.*)") {
            set $unencoded_arg_substitute_url 'https://REDACTED.atlassian.net/wiki/pages/viewpage.action?spaceKey=$2&title=$3';
            set $substitute_url  $unencoded_arg_substitute_url;
            rewrite ^ $substitute_url permanent;
        }

        if ($request_uri ~* "https:\/\/confluence\.REDACTED\.nl\/pages\/viewpage.action\?pageId=(.*)") {
            set $unencoded_arg_substitute_url 'https://REDACTED.atlassian.net/l/cp/VjEHCLZv';
            rewrite ^ $unencoded_arg_substitute_url redirect;
            proxy_pass $unencoded_arg_substitute_url;
        }

        if ($substitute_url = '') {
            set $unencoded_arg_substitute_url 'https://REDACTED.atlassian.net/wiki';
            rewrite ^ $unencoded_arg_substitute_url break;  
            return 301 $unencoded_arg_substitute_url;  
        }

        proxy_pass $unencoded_arg_substitute_url;
        proxy_set_header Host REDACTED.atlassian.net/wiki;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_next_upstream error timeout http_500 http_502 http_503 http_504;
        root /var/www;
        index index.html;
        error_page 502 503 504 fallback.html;
        error_page 404  not_found.html;
        error_page 401 unauthorized.html;
    }
}

通过添加休息标记到改写指令位于“if ($substitute_url = '')”块中，您应该能够保留 URL 中的 + 字符。后续的 return 301 行执行重定向并保留 + 字符。
希望这对您有用。
