本人使用的是阿里云服务器,想使用php长连接,实时从天猫获取数据,代码在本地测试可行,但是上传到服务器上就,不能使用。求指导!以下是phpinfo,
回复讨论(解决方案)
要看到的的代码
代码没有问题,就这个也运行不了
<?phpheader("Content-type: text/html; charset=utf-8"); echo "每隔3秒输出一次<br />";set_time_limit(0); //保证php程序运行不超时退出while(1) { echo date("H:i:s")."<br />"; ob_flush(); flush(); //刷新并输出PHP缓冲数据 sleep(3); //延迟3秒}?>
要看到的的代码
有什么好的意见吗? 1、你 #2 的代码并非长连接,与你的问题有什么关系?
2、你 #2 的代码只是利用了服务器的一个缺陷而达到的视觉效果,并无实用价值
3、你从 阿里云 到 天猫 获取数据,这本身是需要有做够的权限的
而云服务无一例外的禁用了免费的文件操作,那么你是怎么保存与 天猫 沟通时的 cookie 的?

首先感谢回复,谢谢,请教一下,长连接,这方面不懂。我想的是用长连接,接收数据,这样天猫一推送数据,我立马就可以收到。

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
