Spring Cloud Gateway收到的是http请求，但schema却是https

问题描述

为了方便说明问题，这里把问题简化下（实际上通过下面简化后的描述就暗示了是部署环境导致的问题，实际情况并没有这么顺利，中间经历过崩溃、搞不懂、超出认知、持续折腾了一周，各种实验、怀疑过这种问题，比如ingress自动申请的证书问题、ingress没有正确终止ssl，甚至还重新装过k3s，也怀疑过事traefix nginx的问题，哎，反正各种问题都怀疑完了，然后各种验证，崩溃完了）

有个nginx，跑了一个前端代码，配置文件大概这样：

server
{
    listen 80;
    listen 443 ssl  http2;
    server_name xxxxx.top;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/wwwroot/xxxxx.top;

    #HTTP_TO_HTTPS_START
    if ($server_port !~ 443){
        rewrite ^(/.*)$ https://$host$1 permanent;
    }

        return 403;
    }

    
    location ^~ /ly {
        root /www/wwwroot/xxxxx.top;

        try_files $uri /ly/index.html;
        index  index.html index.htm;
        error_page 405 =200	http://$host:$server_port$request_uri;
        error_page 404 = /404.html;
    }
    
    location /api {
        proxy_set_header   Host $host:$server_port;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_connect_timeout 60;
        proxy_read_timeout 600;
        proxy_send_timeout 600;
        proxy_pass http://10.1.12.7:8760/api;
        #proxy_pass http://10.1.12.7:31760/api;
        client_max_body_size 80m;
    }
    
    access_log  /www/wwwlogs/xxxxx.top.log;
    error_log  /www/wwwlogs/xxxxx.top.error.log;
}

http://10.1.12.7:8760/apiopen in new window 指向的是一个spring cloud gateway服务，这个gateway是用docker-compose部署的，采用的镜像比如是：a.com/gateway:1.0，部署的服务器内网ip是：10.1.12.7open in new window

然后有一天我再同样的服务器上用同样版本的镜像：a.com/gateway:1.0，通过k3s部署了一下，然后通过service暴露到节点上，节点端口是31760，那么访问地址就是：open in new window http://10.1.12.7:31760/apiopen in new window

然后把上面的http://10.1.12.7:8760/apiopen in new window 改为 http://10.1.12.7:31760/apiopen in new window ，也就是指向了通过k3s部署的那个gateway服务。

然后通过https://xxxxx.top/api/xxxxx进行访问，奇怪的事情发生了，会出现这样的异常信息：open in new window

排查过程

此处省略10000字，如果真的把整个过程写下来的，估计10000字都不够。

中途通过gateway 端口的入站请求包，发现是http请求，但日志里或者通过exchange.getRequest().getURI().getSchema()却返回https

和这个头有关：X-Forwarded-Proto: https

罪魁祸首

配置： server.forward-headers-strategy

由于配置文件中其实没有配置这个的参数的，所以导致了不同部署环境有不同的表现。

然后也正式因为没有配置这个参数，到最后定位到这个参数也是相当坎坷。

我们底层采用的事Undertow，undertow在没有配置这个参数的情况下不同的部署环境有不同的行为：

具体就请各位自己看代码了。

再我的这个情况下需要设置为 none . 尝试过fremework也不行

系统推荐

随机毒鸡汤：学习过滤得了学渣，却过滤不了人渣。

Spring Cloud Gateway收到的是http请求，但schema却是https
