我正在使用Zapier代码（Javascript）调用第三方API来转换货币。每次我按下Zap时，它将进行约40次API调用。
我正在使用setTimeout进行延迟，并确保这些值可用并且API调用已完成，然后再通过Zapier的输出变量将其发送到下一步，但似乎它们被忽略了...整个zapier操作将在384毫秒内执行。
我与Zapier进行了交谈，并被告知他们确实支持setTimeout。我究竟做错了什么？我无法弄清楚...：）

答案 0 :(得分：0)
根本问题是setTimeout的运行不像您期望的那样。尝试在JS解释器中运行它：
const st = () => {
setTimeout(()=>console.log('done'), 3000)
return 3
}
st()
3立即打印，然后3秒钟（如果解释器仍处于活动状态，则打印'done'。这是因为setTimeout不会阻止执行-它只是排队n秒后执行一个操作（回调结果）。this答案中有更多信息。
要记住的一大事情是Zapier并没有在代码中做任何特别神奇的事情。有一个包装器可以处理lambda，就是这样。因此，如果将现有代码复制到函数中并运行它，则应该看到Zapier会得到的相同内容-执行立即完成，并且不返回任何内容。
要解决此问题，您将需要await个getConversionAsync电话。但是，您执行Zapier的时间有限，因此您希望并行执行尽可能多的请求。
为此，做出大量承诺并将它们全部包装在Promise.all中。我不太肯定您不会用完时间，但这至少会让您朝正确的方向前进。
答案 1 :(得分：0)
我尝试了上述有针对性的想法，并删除了所有可重用性。现在，只有一堆带有等待行的语句-据我所知-将按顺序运行它们吗？
无论如何，动作在200毫秒内完成，这意味着它甚至都没有等待。
当我在Zapier以外的常规环境中运行此代码时，它可以很好地完成-大约需要5秒钟来运行所有内容。
我还想念什么吗？假设我还是不明白哈哈：）

getConversionAsync();```
答案 2 :(得分：0)
几点：
请勿使用setTimeout()。您只能猜测超时值。 5000，或其他任何内容，可能太长或太短。允许fetch()和response.json()返回的承诺来确定时间很简单-无需猜测。
允许您的函数接受参数并返回结果。这样，调用者函数可以直接与返回的值/对象和外部成员一起使用，例如dAmt，dOOP，dGM，fAmt，fOOP，{{ 1}}，可以避免；大多数将成为fGM的内部成员。
由于getConvertedAmounts()是异步的，并且getConversionAsync调用getConvertedAmounts()，因此getConversionAsync()也（根据定义）也是异步的。
无需初始化getConvertedAmounts()。如果任何output调用失败，则可以使用getConversionAsync()中的错误处理来设置转换的默认值。
fetch()的数量可以用几行代码来程序化。
您可能最终会遇到这样的情况：
