php读取不到https的域名

因测试环境php遇到无法正常读取到https的域名，但是域名配置了ssl证书，故做如下排查。

php测试代码如下

$config[‘base_url‘] = ‘‘;

#开启调试模式
#echo "<pre>";print_r($_SERVER);die;

$http_type = ((isset($_SERVER[‘HTTPS‘]) && $_SERVER[‘HTTPS‘] == ‘on‘) || (isset($_SERVER[‘HTTP_X_FORWARDED_PROTO‘]) && $_SERVER[‘HTTP_X_FORWARDED_PROTO‘] == ‘https‘)) ? ‘https://‘:"http://";
define(‘HTTP_TYPE‘, $http_type);//定义当前域名使用协议是http还是https
define(‘URL‘, $http_type.$_SERVER[‘HTTP_HOST‘]);
define(‘OLD_URL‘, $http_type.$_SERVER[‘HTTP_HOST‘]);//老版本专用

通过上述代码调试出来如下结果。

)

确实没有打印到https被开启的相关内容，检查nginx反向代理配置文件的ssl配置部分。

upstream xxxx.com {
        server 10.10.10.208:80;
}
server{
    listen 443; 
    server_name xxxx.com;
    ssl                  on;
    ssl_certificate      /etc/nginx/crt/xxxx.com/xxxx.com.crt;
    ssl_certificate_key  /etc/nginx/crt/xxxx.com/xxxx.com.key;
    ssl_session_timeout  5m;
    location / {
        proxy_pass         http://xxxx.com;
        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
    }
}

发现上述配置文件ssl证书正常，但是PHP获取不到X-Forwarded-Proto或者HTTPS的变量值，尝试在反向代理配置中加入以下配置。

proxy_set_header   X-Forwarded-Proto $scheme;

再次通过php调试打印出现https内容。

[HTTP_X_FORWARDED_PROTO] => https
[HTTPS] => on

再次访问PHP的内容已经恢复正常。
