varnish - 如何使用 Varnish 添加重定向异常？

Question

我正在尝试将路径例如 www.something.com/apple/pie 重定向到 www.something.com/tickets/pie-details 但也有一些例外情况，例如 www.something.com/apple/helloworld 不会被重定向到 www .something.com/tickets/helloworld-details

这是我尝试过但不起作用的方法：

if (req.url ~ "^/apple/.*" && req.url != "^/apple/helloworld") {
    set req.url = "^/tickets/.*-details";
    error 701 req.url;
}

举个例子（直接来自帖子）：

sub vcl_recv {
    if (req.http.host != "www.varnish-software.com") {
        set req.http.location = "https://www.varnish-software.com/";
        return(synth(301));
    }
}
sub vcl_synth {
    if (resp.status == 301 || resp.status == 302) {
        set resp.http.location = req.http.location;
        return (deliver);
    }
}

您还需要req.http.location正确书写。据我了解，你想要这样的东西：

sub vcl_recv {
    if (req.url ~ "^/apple/.*" && req.url != "^/apple/helloworld") {
        set req.http.location = "/tickets + req.url + "-details";
        return(synth(301));
    }
}

我认为做一个正则表达式替换会更好。

if (req.url ~ "^/apple/.*" && req.url != "^/apple/helloworld") {
  set req.url = regsub(req.url, "^/apple/", "/tickets/");
  error 701 req.url;
}
