新建了个网站想配置webdav，dav_ext_methods PROPFIND OPTIONS LOCK UNLOCK;，配置文件一加上这段就报错无法保存，不加又405 Not Allowed，这个该怎么解决呢？
服务内部错误: stderr: 2024/04/29 10:04:18 [emerg] 44#44: unknown directive “dav_ext_methods” in /usr/local/openresty/nginx/conf/conf.d/webdav.conf:42 nginx: [emerg] unknown directive “dav_ext_methods” in /usr/local/openresty/nginx/conf/conf.d/webdav.conf:42 nginx: configuration file /usr/local/openresty/nginx/conf/nginx.conf test failed
