使用 nginx 重写规则获取“重定向过多”错误

  • 772

我正在尝试重写以我的站点为目标的域 url，以便将所有域名都重写为 www.example.com 并具有以下配置：

我的网站块

  server {      
        listen       80 default_server;
        listen   [::]:80 default_server ipv6only=on;

            server_name _;
            rewrite ^ $scheme://www.example.com$request_uri permanent;

    location / {

            # Allow for large file uploads
              client_max_body_size 0;

                proxy_http_version 1.1;
                proxy_pass http://mysite;
                proxy_buffering    off;

                proxy_set_header   X-Real-IP $remote_addr;
                proxy_set_header   X-Scheme $scheme;
                proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header   Host $http_host;
    }
}

tomcat 服务器块

server {
        listen        80;

        root /opt/site2/www;
        index index.html index.htm;

        # Redirecto root requests to Share
        rewrite ^/$ /share;

        location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ /index.html;
        }

        # redirect server error pages to the static page /50x.html
        error_page 502 503 504 /maintenance.html;
            location = /maintenance.html {
            root   /opt/site2/www;
        }

        location /share {

            # Allow for large file uploads
            client_max_body_size 0;

            # Proxy all the requests to Tomcat
            proxy_http_version 1.1;
            #proxy_buffering off;
            proxy_pass http://backend;
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Host $http_host;
            proxy_set_header X-Forwarded-Server $host;
        }

}

在服务器块中，但我收到“重定向过多”错误。

    现在任何和所有请求都将到达这个服务器块：

    server {      
    listen    80 default_server;
    listen    [::]:80 default_server ipv6only=on;

    server_name _; # This doesn't do anything
    rewrite ^ $scheme://www.example.com$request_uri permanent;

    # Rest of file irrelevant
}

    因为：没有服务器块有一个有效的server_name（因此永远不会有主机名匹配），这是 default_server。

    使用适当的服务器名称

    因此，要始终将命中服务器的请求重定向到给定的主机名，请确保有一个明确的服务器块www.example.com：

    server {      
    listen    80;
    listen    [::]:80 ipv6only=on;

    server_name www.example.com;

    # Everything else from "Tomcat server block" 
    # or the proxy_pass config as appropriate
}

    并将具有任何其他主机名的请求重定向到它：

    server {      
    listen    80 default_server;
    listen    [::]:80 default_server ipv6only=on;

    return 301 http://www.example.com$request_uri;

    # Nothing else, because it wouldn't do anything
}

    在上面的注释中，return 301它被认为是比无条件重写规则更好的做法。
