Error during parsing: parsing caddyfile tokens for 'forward_proxy': /etc/caddy/Caddyfile:5...

[mattieross]

按照项目主页的示例在服务器编译caddy，运行caddy报错并退出， Caddyfile也是按照example配置，在85版本可以正常运行。 日志如下：

caddy[542]: run: adapting config using caddyfile: parsing caddyfile tokens for 'route': /etc/caddy/Caddyfile:11 - Error during parsing: parsing caddyfile tokens for 'forward_proxy': /etc/caddy/Caddyfile:5 - Error during parsing: Wrong argument count or unexpected line ending after 'password'

systemd[1]: caddy.service: Main process exited, code=exited, status=1/FAILURE

systemd[1]: caddy.service: Failed with result 'exit-code'.

Caddy版本跟naive无关

而且你肯定不是按照example配置

因为如果Caddyfile按照example一字不变，可以得到如下结果：

2020/10/10 13:31:18.345 INFO    using adjacent Caddyfile
2020/10/10 13:31:18.346 INFO    admin   admin endpoint started  {"address": "tcp/localhost:2019", "enforce_origin": false, "origins": ["localhost:2019", "[::1]:2019", "127.0.0.1:2019"]}

2020/10/10 13:31:18.346 INFO    http.handlers.forward_proxy Secret domain used to connect to proxy: secret.com

并没有你给出的错误

感谢回复， 我又测试了几遍， 一字不变用Caddyfile还是跑不起来， 然后改用以前的json配置就可以启动caddy，

我也试了几次 也有一模一样的问题

[GWONGJYULEI]

I built caddy v2.2.0 with the latest forwardproxy in my virtual ubuntu-20 in PC today, and following klzgrad`s tutorials. There is no error when the self-built caddy run with the Caddyfile as following:

:443, xxx.com
tls xxx@xxx.com
route {
  forward_proxy {
    basic_auth USER PASSWORD
    hide_ip
    hide_via
    probe_resistance xxx.com
  }
  file_server { root /var/www/html }
}

And the following is my building commands:

git clone -b naive https://github.com/klzgrad/forwardproxy
go get -u github.com/caddyserver/xcaddy/cmd/xcaddy
~/go/bin/xcaddy build --with github.com/caddyserver/forwardproxy=$PWD/forwardproxy

[klzgrad]

Caddy 2的Caddyfile语法跟1不一样，调整一下Caddyfile

[mattieross]

抱歉，是我的错！ basic_auth 写成 basicauth 少了个下划线。
