400错误请求 - 请求标头或Cookie太大

Question

我收到了一个400错误请求请求标头或cookie，它与我的Rails应用程序中的nginx太大。重新启动浏览器可以解决问题。我只在我的cookie中存储字符串ID，所以它应该很小。

我在哪里可以找到nginx错误日志？我查看了nano /opt/nginx/logs/error.log，但它没有任何关联。

我试图设置以下和没有运气：

location/{ 
    large_client_header_buffers 4 32k; 
    proxy_buffer_size 32k; 
} 

nginx.conf

#user nobody; 
worker_processes 1; 
#error_log logs/error.log; 
#error_log logs/error.log notice; 
#error_log logs/error.log info; 
#pid  logs/nginx.pid;

    worker_connections 1024;

# } 
    #error_page 404    /404.html; 

    # redirect server error pages to the static page /50x.html 
    # 
    error_page 500 502 503 504 /50x.html; 
    location = /50x.html { 
     root html; 
    } 

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

    # fastcgi_index index.php; 
    # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; 
    # include  fastcgi_params; 
    #} 

    # deny access to .htaccess files, if Apache's document root 
    # concurs with nginx's one 
    # 
    #location ~ /\.ht { 
    # deny all; 
    #} 
} 


# another virtual host using mix of IP-, name-, and port-based configuration 
# 
#server { 
# listen  8000; 
# listen  somename:8080; 
# server_name somename alias another.alias; 

# location/{ 
#  root html; 
#  index index.html index.htm; 
# } 
#} 


# HTTPS server 
# 
#server { 
# listen  443; 
# server_name localhost; 

# ssl     on; 
# ssl_certificate  cert.pem; 
# ssl_certificate_key cert.key; 

# ssl_session_timeout 5m; 

# ssl_protocols SSLv2 SSLv3 TLSv1; 
# ssl_ciphers HIGH:!aNULL:!MD5; 
# ssl_prefer_server_ciphers on; 

# location/{ 
#  root html; 
#  index index.html index.htm; 
# } 
#} 

} 

这里是我的代码存储的cookie和在Firebug的Cookie截图。我用萤火虫检查存储的会话，我发现New Relic和jQuery也存储cookie;这可能是为什么超过cookie大小？

def current_company 
    return if current_user.nil? 
    session[:current_company_id] = current_user.companies.first.id if session[:current_company_id].blank? 
    @current_company ||= Company.find(session[:current_company_id]) 
end 

Answer 1

这只是错误怎么说 - Request Header Or Cookie Too Large。其中一个标题非常大，而nginx则拒绝它。

您正在对large_client_header_buffers正确的方向前进。如果您使用check the docs，您会发现它仅在http或server上下文中有效。将它撞上一个服务器模块，它就可以工作。

server { 
    # ... 
    large_client_header_buffers 4 32k; 
    # ... 
} 

顺便说一句，默认的缓冲区数量和大小是4和8k，使你的坏头必须是一个最超过8192个字节。在你的情况下，所有这些cookie（合并为一个头）都远远超过limit。特别是那些mixpanel饼干变得相当大。

Answer 2

固定加入

server { 
    ... 
    large_client_header_buffers 4 16k; 
    ... 
} 

Answer 3

对于以上的答案，但有client_header_buffer_size需要提到：

http { 
    ... 
    client_body_buffer_size  32k; 
    client_header_buffer_size 8k; 
    large_client_header_buffers 8 64k; 
    ... 
}
