以下是 Caddyfile 的标准指令。
| acme_server | An embedded ACME server |
| basicauth | Enforces HTTP Basic Authentication |
| bind | Customize the server's socket address |
| encode | Encodes (usually compresses) responses |
| file_server | Serve files from disk |
| handle | A mutually-exclusive group of directives |
| handle_errors | Defines routes for handling errors |
| handle_path | Like handle, but strips path prefix |
| header | Sets or removes response headers |
| import | Include snippets or files |
| log | Enables access/request logging |
| php_fastcgi | Serve PHP sites over FastCGI |
| redir | Issues an HTTP redirect to the client |
| request_header | Manipulates request headers |
| respond | Writes a hard-coded response to the client |
| reverse_proxy | A powerful and extensible reverse proxy |
| rewrite | Rewrites the request internally |
| root | Set the path to the site root |
| route | A group of directives treated literally as single unit |
| templates | Execute templates on the response |
| tls | Customize TLS settings |
| try_files | Rewrite that depends on file existence |
| uri | Manipulate the URI |
指令的语法格式如下：
directive [<matcher>] <args...> { subdirective [<args...>] }
< > 中使用实际的值替换，[ ] 代表是可选的参数，... 代表一个或多个值。
大多数指令接受 [<matcher>] 来过滤请求，表示不同的请求使用不同的指令。
许多指令操纵 HTTP 处理程序链。这些指令的求值顺序很重要，因此默认的顺序被硬编码到 Caddy 中。
root
header
redir
rewrite
uri
try_files
basicauth
request_header
encode
templates
handle
handle_path
route
respond
reverse_proxy
php_fastcgi
file_server
acme_server
如果需要自定义顺序，可以使用 order 全局选项，或者 route 指令。
