When you are using the FastCGI Php version, you would set HTTPS variable if you are serving parts of you website with SSL.To do that, add the following function into the http section of your nginx configuration(以下内容添加到http字段内)：
map $scheme $fastcgi_https { ## Detect when HTTPS is used
default off;
https on;
}
以下内容添加到server字段内：
fastcgi_param HTTPS $fastcgi_https;
