检查 cookie 是否不包含指定内容 NGINX

Question

关于检查 cookie 是否存在并包含我的内容的教程数不胜数，在本例中 foobar。

假设 mycookie 是我要设置的 cookie，我该如何执行以下操作。

if ($cookie_mycookie does not equal "foobar") {
  return 401;
}

我试过以下方法都无济于事。

if (!$http_mycookie ~* "foorbar" ) {
  return 401;
}

谢谢！

在 Nginx 中，每个 cookie 都可以在嵌入式变量中使用 $cookie_CookieName。如果您想检查名称为 mycookie 的 cookie，您可以使用此配置片段来完成：

if ($cookie_mycookie != "foobar") {
  return 401;
}

来自 nginx manual 的 if 命令：

A condition maybe (among others):

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 .. 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.
