Nginx upstream sent too big header while reading response header from upstream

upstream sent too big header while reading response header from upstream
在http字段里添加

http {
    ...
    proxy_buffers 8 16k;
    proxy_buffer_size 32k;
    }

如果是fastcgi的话

http {
    ...
    fastcgi_buffers 8 16k;
    fastcgi_buffer_size 32k;
}
