如何防止nginx读取整个url

我的web服务需要很长的URL。 我想在URL前面是“/get/”时响应index.html，不管后面会发生什么， 但NGINX似乎读取整个URL，它抛出错误“mallocfailed”

如何防止nginx读取整个URL

    server {
        listen  80;
        access_log off;

        # large_client_header_buffers 4 1024m; # It works, but i don't want to use memory for it.

        root /etc/nginx/static/;
        error_page 404 /404.html;

        location /get/ {
            try_files /index.html =404;
        }
        location / {
            try_files $uri $uri/ /index.html;
        }
    }
