[求助]Openshift 的 nginx-php7 配置重定向 https 时出现循环重定向

可能用了假的 nginx ， default.conf.erb 写法
server {
root <%= ENV['OPENSHIFT_REPO_DIR'] %>/www;
listen <%= ENV['OPENSHIFT_PHP_IP'] %>:<%= ENV['OPENSHIFT_PHP_PORT'] %>;
server_name <%= ENV['OPENSHIFT_APP_DNS'] %>;
index index.php index.html index.htm <%= ENV['NGINX_EXTRA_INDEX'] %>;
set_real_ip_from <%= ENV['OPENSHIFT_PHP_IP'] %>;
real_ip_header X-Forwarded-For;

# Redirect all HTTP requests to HTTPS with a 301 Moved Permanently response.
if ($server_port = 80){
return 301 https://$server_name$request_uri;}
if ($scheme = http){
return 301 https://$server_name$request_uri;}

# avoid caching by proxies
add_header Cache-Control private;

location ~ \.php$ {
try_files $uri =404;
fastcgi_pass unix:<%= ENV['OPENSHIFT_PHP_DIR'] %>/run/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
include openshift_params;

# uncomment to export all environment variables to fastcgi
#include <%= ENV['OPENSHIFT_REPO_DIR'] %>/config/nginx.d/export_env;
}

# avoid unnecessary log
location = /favicon.ico {
access_log off;
log_not_found off;
}

location = /robots.txt {
access_log off;
log_not_found off;
}

# Handle any other URI
location / {
try_files $uri $uri/ =404;
}
}
