Question

我正在尝试为wordpress网站创建一个清漆文件，但是我收到以下编译错误：

varnish_1   | Message from VCC-compiler:
varnish_1   | Unused acl purge, defined:
varnish_1   | ('input' Line 22 Pos 5)
varnish_1   | acl purge {
varnish_1   | ----#####--
varnish_1   |
varnish_1   | Running VCC-compiler failed, exited with 2
varnish_1   |
varnish_1   | VCL compilation failed
wp1_varnish_1 exited with code 2

vcl文件位于下方。如果你删除acl清除功能它完全正常。有任何想法吗？提前致谢。

编译器告诉你问题，你已经找到了解决方案，删除了名为purge的未使用的acl：

Unused acl purge, defined:

另一个选项是添加一个检查以仅允许从该acl中清除：

if (req.method == "PURGE") {
    if (!client.ip ~ purge) {
        error 405 "Not allowed.";
    }
