通过 https2http 插件可以让本地 HTTP 服务转换成 HTTPS 服务对外提供。
frps.ini 内容如下：
[common]
bind_port = 7000
vhost_https_port = 443
frpc.ini 内容如下：
[common]
server_addr = x.x.x.x
server_port = 7000
[test_htts2http]
type = https
custom_domains = test.yourdomain.com
plugin = https2http
plugin_local_addr = 127.0.0.1:80
# HTTPS 证书相关的配置
plugin_crt_path = ./server.crt
plugin_key_path = ./server.key
plugin_host_header_rewrite = 127.0.0.1
plugin_header_X-From-Where = frp
分别启动 frps 和 frpc。
