I hava a problem with axios-ie;

[VN666]

when I use axios-ie in node env, do a post request to nginx, it's Ok, but when I use axios do the same things, nginx will change the POST request to GET request, why?

the nginx is as follow:

server {
listen 80;
server_name xx.xx.com;
rewrite ^(.*) https://$server_name$1 permanent;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}

server {
	listen 80;
	server_name 127.0.0.1;
    rewrite  ^(.*) http://xx.xx.com$1 permanent;
}

now I'm very anxious， please help me！thanks！
