Nginx 414 Request-URI Too Large error solution

When the requested parameter is too long, nginx will report an error

We only need to add two lines to the http of nginx.confg

client_header_buffer_size 512k; 
large_client_header_buffers 4 512k;

It is found that the request will report an error again

java.lang.IllegalArgumentException: Request header is too large

Then add max-http-header-size to the springboot configuration file

server:
  max-http-header-size: 102400
