WordPress中图片等内容防盗链

通过 Nginx 实现防盗链

在这个网络有宽带有上限，流量收费的环境下，图片防盗链接就有实际意义了。

        # 防盗链，valid_referers none blocked 可允许无引用访问。
        #location ~* /wp-content/.*(gif|png|jpeg|jpg|svg|7z|zip|rar|exe|pdf)$ {
        location ~* ^/wp-content/uploads/20.*$ {
            root   D:/WordPress;
            valid_referers y.z *.y.z *.google.com *.bing.com *.baidu.com;
            if ($invalid_referer) {
                return 301 https://y.z/anti-theft.png;
            }
        }

防盗链中开放特定ip：word博客场景

        # 防盗链，【valid_referers none blocked】可允许无引用访问，PDF.js View插件是有引用访问。
        #location ~* /wp-content/.*(gif|png|jpeg|jpg|svg|7z|zip|rar|exe|pdf)$ {
        location ~* ^/wp-content/uploads/20.*$ {
            # IP检查通过，赋值为1；win版nginx没有geo或map模块。
            set $bypass_ref 0;
            # ip段的条件：($remote_addr ~ ^10\.0\.0\.)
            if ($remote_addr = 1.2.3.4) {
                set $bypass_ref 1;
            }
            valid_referers y.z *.y.z *.google.com *.bing.com *.baidu.com;
            # 无效引用访问，赋值为${bypass_ref}1
            if ($invalid_referer) {
                set $bypass_ref "${bypass_ref}1"; 
            }
            # ip检查失败=0，无效引用访问=1
            if ($bypass_ref = 01) {
                return 301 https://y.z/anti-theft.png;
            }
