Question

我已经制作了一个用于直播布局的网页，有没有办法加快加载过程？因为加载有点慢到我的标准，加载需要大约5-10秒，这是慢的方法，我重写了很多代码，使方法更通用，但是这个过程仍然占用很长，也许问题在于第一种方法（value_in），但我确实不知道。

Answer 1

你是对的，5到10秒很慢。但它可能与您自己的代码无关。多次调用外部API是使速度减慢的部分。

如果事先知道您对外部Web服务进行的调用，则应该尝试每隔一分钟左右进行一次后台进程轮询并缓存结果。然后，您的实际脚本可以访问缓存的结果，这将快得多。

Answer 2

使用缓存机制和时间戳超时。那就是你的数据保持更新，你的服务器一直没有大量的请求。

Answer 3

数据的变化频率如何？如果它不经常更改，请有一个生成并保存文件ss html的计划任务（cron），以便浏览器只加载html。

Answer 4

您正在访问外部API。你受其他网站的支配。
