1、采用动态不规则的html标签
2、限制IP
和搜索引擎没有矛盾的，完全可以用nginx判断是否是搜索引擎爬虫，指引到一个固定的html结构的里边，以前就这样做过
避免是很难的，只能说尽量提高抓取的成本。
常见都是在nginx或者程序中加入频率限制（rate limit）
把网站关了即可.
在robots.txt中添加屏蔽抓取的策略，就能少被采集了
关键是你又希望搜索引擎来爬你；
所以这是矛盾的，
只能尽量做好；
you can't.
楼上都没答到点子上，一般采集无非就是用硬抓取，如file_get_contents，和模拟抓取，如casperjs，我曾经用casperjs来写爬虫，速度实在太慢，所以casperjs爬虫不太可行，如果只是像file_get_contents之类的，后台分析日志，凡是加载的网页没有加载对应的css和js文件的，全部ban掉
希望写小偷程序的人不要看到这个答案，要不除了限制请求频率根本没法了，哦忘了，我就是专门写小偷程序的
cnzz统计的问题，加个谷歌统计对比下，流量差距就出来了，有10倍左右，猜测应该是百度蜘蛛之类的，识别为用户了，我的展也这样

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
