用于校验资源请求的合法性
server {
listen 3300;
server_name www.siguoya.name;
root /usr/local/nginx/1.12.1/html;
location / {
secure_link $arg_md5,$arg_expires;
secure_link_md5 "$secure_link_expires$uri siguoya";
if ($secure_link = "") {
return 403;
}
if ($secure_link = "0") {
return 410;
}
}
}如果是访问 http://www.siguoya.name:3300/index.html?expires=111 的话，md5 值的 shell 计算方法如下：
echo -n '111/index.html siguoya' | openssl md5 -binary | openssl base64 | tr +/ -_ | tr -d =http://www.siguoya.name:3300/index.html?expires=111&md5=111 | 403，md5不正确，时间过期 |
http://www.siguoya.name:3300/index.html?expires=2147483647&md5=111 | 403，md5不正确，时间未过期 |
http://www.siguoya.name:3300/index.html?expires=111&md5=cLdY2ROg2kZDD0xkWaJ8TQ | 410，md5正确，时间过期 |
http://www.siguoya.name:3300/index.html?expires=2147483647&md5=GfmT6Hj3U55xfQJ3aNqjfQ | 200，md5正确，时间未过期 |
