我想一个模块(节点8.9.0LTS)内的以下内容:的Node.js的setTimeout方面的问题
const someResponse = await ajaxService.post('/data/search', params)
const ms = 2000;
const intervalID = setInterval(function(){
if(Object.keys(personDataResponse).length === 0){
let url = `/api?searchRequestId=1111`
response = await ajaxService.get(url)
}
}, ms);
setTimeout(function() {
clearInterval(intervalID);
}, ms * 5);
但我收到以下:
/path/to/project/project/api/router.js:27
response = await ajaxService.get(url)
^^^^^^^^^^^

有什么建议? ajaxService.get()在setTimeout之外是可访问的。
'setInterval'的意图是在这里?看起来你每两秒运行一次请求五次,然后停止它。 – JLRishe
