    即所有访问客户端必须包含一个 cookie 名为 abc ,如不包含该 cookie 即禁止访问

    不在服务器端处理,仅在 nginx 中是否可以做到?谢谢!

    试试这样能能否符合你的需求

    set $auth_cookie 0;
    if ($http_cookie ~* "AUTH_COOKIE=([a-z0-9]+)(?:/|$)") {
    set $auth_cookie 1;
    }

    if ($auth_cookie = 0) {
    return 403;
    }

    location / {
    if ( $cookie_antiscanpassword != "password") {
    return 403;
    }
    proxy_pass http://127.0.0.1;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    @jarlyyn 谢谢,很有帮助

    如果仅判断 cookie 是否存在怎么处理?实际生产环境中 abc 的 cookie 值每个用户是不同的,没法这样写在配置里判断

    @jarlyyn

    if ( $cookie_antiscanpassword != "password") {
    这句是判断名为 antiscanpassword 的 cookie 值是否为 "password" 吧?而不是判断 antiscanpassword 是否存在

    应该是直接 if ( $cookie_antiscanpassword),不行的话正则处理 if ( $cookie_antiscanpassword~ .+)

    参考 http://nginx.org/en/docs/http/ngx_http_rewrite_module.html

    a variable name; false if the value of a variable is an empty string or “ 0 ”;
    Before version 1.0.1, any string starting with “ 0 ” was considered a false value.
    comparison of a variable with a string using the “=” and “!=” operators;
    matching of a variable against a regular expression using the “~” (for case-sensitive matching) and “~*” (for case-insensitive matching) operators. Regular expressions can contain captures that are made available for later reuse in the $1..$9 variables. Negative operators “!~” and “!~*” are also available. If a regular expression includes the “}” or “;” characters, the whole expressions should be enclosed in single or double quotes.
    checking of a file existence with the “-f ” and “!-f ” operators;
    checking of a directory existence with the “-d ” and “!-d ” operators;
    checking of a file, directory, or symbolic link existence with the “-e ” and “!-e ” operators;
    checking for an executable file with the “-x ” and “!-x ” operators.
