Varnish 不启动语法错误

Question

我绞尽脑汁想弄清楚我的 .vcl 文件中的语法有什么问题。我一直收到错误消息：

Symbol not found: 'req.method' (expected type BOOL):
('input' Line 13 Pos 9)
    if (req.method == "PURGE") {
--------##########--------------

Running VCC-compiler failed, exit 1

我正在学习本教程https://www.varnish-software.com/blog/step-step-speed-wordpress-varnish-software

谁能看出我做错了什么？

如果您使用的是 varnish 3.x 而不是 4.x：将 req.method 替换为 req.request

if (req.request == "PURGE") {
