无法判断是否 https 请求

Question

http 网站升级 https 在 https 状态下打印 $_SERVER ["REQUEST_SCHEME"] => string(4) "http" ["SERVER_PROTOCOL"] => string(8) "HTTP/1.0" 等信息全是http,这是什么原因?? 　 先谢谢大家回答，我的 $_server 全部都没有标识https;附上我的nginx 配置 server { listen 80; root /www; server_name xx.com; rewrite ^(.*)$ https://$host$1 permanent; index index.html index.php index.htm; location ~ \.php$ { proxy_pass http://127.0.0.1:88; include naproxy.conf; } location ~ /\.ht { deny all; } location / { try_files $uri @apache; } location @apache { internal; proxy_pass http://127.0.0.1:88; include naproxy.conf; } } server { listen 443; root /www; ssl on; ssl_certificate cert/xx.com.crt; ssl_certificate_key cert/xx.com.key; ssl_prefer_server_ciphers on; ssl_session_timeout 10m; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; server_name xx.com; index index.html index.php index.htm; location ~ \.php$ { proxy_pass http://127.0.0.1:88; include naproxy.conf; } location ~ /\.ht { deny all; } location / { try_files $uri @apache; } location @apache { internal; proxy_pass http://127.0.0.1:88; include naproxy.conf; } }

Answer 1

$_SERVER['HTTPS']

$_SERVER['SERVER_PORT'] == 443

Answer 2

nginx fastcgi参数设置了吗

Answer 3

你访问的这个地址，到达的第一个 WEB 服务器（处理了你这个 HTTPS 的请求的那个），与你在页面中看到的那个 php 服务器，又不一定是同一个东西。

Answer 4

$_SERVER ['HTTP_X_FORWARDED_PROTO']

Answer 5

isset($_SERVER['HTTPS']) && ($_SERVER['HTTPS'] == "on")
找找这2个有吗，我用这2个判断的，ok的
