Nginx添加标头PHP FPM返回错误

我正在使用带有Nginx和PHP-FPM的Laravel 4来为应用程序提供服务.

该应用程序实现了API,但是我向Nginx添加了一些相当开放的CORS规则,这些规则似乎运行良好.

每当应用程序抛出错误时,Nginx似乎都不会在响应中添加标头.有什么方法可以强制执行此操作,而不必安装更多的标头扩展名？

我的配置如下：

server {
    listen 80;
    server_name mediabase.local;
    root /home/vagrant/mediabase/public;

    index index.html index.htm index.php;

    charset utf-8;

    location / {
        try_files $uri $uri/ /index.php?$query_string;

    add_header Access-Control-Allow-Origin "*";
    add_header Access-Control-Allow-Methods "GET,OPTIONS,POST,HEAD,DELETE,PUT";
    add_header Access-Control-Allow-Headers "Authorization,X-Requested-With,Content-Type,Origin,Accept";
    add_header Access-Control-Allow-Credentials "true";
    add_header Access-Control-Max-Age: 86400;


    }

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

    access_log off;
    error_log  /var/log/nginx/mediabase.local-error.log error;

    error_page 404 /index.php;

    sendfile off;

    location ~ .php${
        fastcgi_split_path_info ^(.+.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;

    add_header Access-Control-Allow-Origin "*";
    add_header Access-Control-Allow-Methods "GET,Accept";
    add_header Access-Control-Allow-Credentials "true";
    add_header Access-Control-Max-Age: 86400;

    }

    location ~ /.ht {
        deny all;
    }
}
