varnish-vcl - 清漆 VCL "Symbol not found: std.querysort"

Question

我正在从 this handy template 复制一些 VCL 规则并在最新稳定的 Varnish4 上运行。但是 VCL 的这一部分:

vcl 4.0;

sub vcl_init {
    # ...

    # Normalize query arguments
    set req.url = std.querysort(req.url);
}
                  ^

返回此错误:

我应该包含一个 mod 还是以某种方式定义 std？

Answer 1

是的!我偶然发现了里面的答案 another answer .在脚本顶部添加 import std; 停止了错误。

vcl 4.0;
import std;

sub vcl_init {
    # ...

    # Normalize query arguments
    set req.url = std.querysort(req.url);
}
