PHP采集超时
写了一个api数据采集的php程序放到服务器,但是数据量巨大,总是会采集超时。请问可以有什么解决方案?有没有办法设置超时之后自动刷新,从断点重新开始运行程序?

采集工作不要使用浏览器进行程序访问 , 使用命令行模式没有超时的情况, 但是使用命令行模式要注意内存的释放,否则会有存在内存溢出的错误, 如果使用浏览器进行程序执行入口 需要增加分页跳转功能, 采集完几个地址后自动跳转一下, 这样就避免超时了 set_time_limit 如果可以调的话可以调的大一点
(补充一点:超时后自动刷新这个没办法实现,超时了程序就已经终止了,只能认为刷新, 从断点开始继续采集这个是有办法的, 每次采集开始时记录一下当前采集链接,结束时把当前采集链接状态设为完成状态,重新开始采集的时候程序自动检测一下这个日志,从有记录的地方开始采集就可以了)
我博客专门有一篇PHP并行采集的文章 比一般的效率高很多

set_time_limit(0); 可以不超时
超时自动刷新的话 没做过 感觉需要用脚本结合PHP返回数据实现
上午刚采集完一大坨数据,用cli模式撒。

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,
