咨询 frpc 如何获取真实 IP

各位大佬 我想通过 frp 内网穿透内网的 Nginx, 并且获取真实 IP ，配置如下 我这边一给 nginx 配置 proxy_protocol 这个参数（就在 ssl 后面的这个地方） 网站就是 502.确定反向代理的网站没有错误

我这边有个测试网站 https://test.guiyun.plus

frpc.ini

[TEST_HTTPS]
type = https
local_ip = 10.0.0.13
local_port = 443
custom_domains = test.guiyun.plus

proxy_protocol_version = v2

plugin = https2https                            
plugin_local_addr = 10.0.0.13:443

#证书相关配置
plugin_crt_path = /etc/frp/ssl/_.guiyun.plus.crt
plugin_key_path = /etc/frp/ssl/_.guiyun.plus.key         
plugin_header_X-From-Where = frp

内网 nginx 配置

upstream test {
    server  127.0.0.1:30080;
}
server {
    listen 80;
    server_name test.guiyun.plus;
    # 强制跳转到 HTTPS
    return 301 https://$host$request_uri;
}

server {

	# 就在下面这行添加 proxy_protocol 。重启 nginx 后网站就会报 502 。
    listen 443 ssl http2 proxy_protocol;
    server_name test.guiyun.plus;

    # SSL 证书相关配置，需要自己替换为自己的证书文件路径和密钥文件路径
    ssl_certificate   ssl/_.guiyun.plus.crt;
    ssl_certificate_key ssl/_.guiyun.plus.key;


    location / {
        proxy_set_header X-Real-IP $proxy_protocol_addr;
        proxy_set_header X-Forwarded-For $proxy_protocol_addr;
        proxy_pass http://test;
    }
}

Frpc 的版本是 0.51.2

Nginx 版本是 nginx/1.18.0 编译参数为
