报错：431 Request Header Fields Too Large

解决方案

报这个错的原因就是，http请求header过大，超过了服务器的限制。

排查Nginx配置文件：nginx.conf

client_header_buffer_size 10240k; large_client_header_buffers 6 10240k;

http { include mime.types; default_type application/octet-stream;

#log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
#                  '$status $body_bytes_sent "$http_referer" '
#                  '"$http_user_agent" "$http_x_forwarded_for"';

#access_log  logs/access.log  main;

client_header_buffer_size 10240k;
large_client_header_buffers 6 10240k; 

} serve{ client——max_size:500m
