nginx防盗链解决方案
方法一：
location ~* \.(js|css|jpg|png|gif|others)$ {
valid_referers none blocked *.sasacity.com sasacity.com;
if ($invalid_referer) {
rewrite ^/ http://www.sasacity.com/logo.gif;
#return 404;
}
}
方法二：
使用ngx_http_accesskey_module模块
配置例子：
location /download {
accesskey on;
accesskey_hashmethod md5;
accesskey_arg "key";
accesskey_signature "mypass$remote_addr";
}
此时客户端访问路径： http://example.com/download/file.zip?key=09093abeac094.
