virtualBox 虚拟机下nginx设置不缓存静态文件不起作用解决办法

最近开发的时候,调整js时会一直使用缓存文件,无法显示改动!
nginx配置静态文件add_header Cache-Control no-cache;也不起作用,很苦恼!

nginx配置代码：
events {
worker_connections 768;
# multi_accept on;
}

http {

##
# Basic Settings
##

sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
# server_tokens off;

# server_names_hash_bucket_size 64;
# server_name_in_redirect off;

include /etc/nginx/mime.types;
default_type application/octet-stream;

##
# SSL Settings
##

ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;

##
# Logging Settings
##

access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;

##
# Gzip Settings
##

gzip on;
gzip_disable "msie6";

# gzip_vary on;
# gzip_proxied any;
# gzip_comp_level 6;
# gzip_buffers 16 8k;
# gzip_http_version 1.1;
# gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

##
# Virtual Host Configs
##

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}

具体配置的server代码：
server {
listen 80 ;
server_name tp.co admin.tp.co;
root /code/think/public;

index index.php;
location ~.*.(js|css|png|jpg)$
{
root /code/think;
add_header Cache-Control no-cache;
}
location / {
if (!-d $request_filename) {
rewrite ^/(.*)/(.*)/*$ /index.php?m=$1&a=$2 last;
rewrite ^(.*)$ /index.php?s=$1 last;
break;
}
}
location ~ .php { #去掉$
fastcgi_pass unix:/run/php/php7.1-fpm.sock;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_split_path_info ^(.+.php)(.*)$; #添加
fastcgi_param PATH_INFO $fastcgi_path_info; #添加
}

}

网上找了一下资料终于解决了!使用virtualBox虚拟机,安装的nginx,不管怎么修改js,css文件,怎么强制刷新设置不缓存,都不管用,原因在于sendfile on;;这个配置在nginx.conf,将sendfile on;改为sendfile off;;再ctrl+F5,OK!完美解决!!
