如何在每次调用之间以1秒的延迟循环播放7次以下的makeHttpRequest
? - 我试过setTimeout
并延迟,但似乎无法解决使用它们的正确方法。使用节点JS中的延迟进行循环播放
var post_data = that.createIRRC("AAAAAQAAAAEAAAB1Aw==");
that.makeHttpRequest(onError, onSucces, "", post_data, false)

如果你想HTTP请求启动下一个之前完成之后停顿一秒,那么你就可以在完成回调使用setTimeout()
。
而且,因为它现在看起来要发送的码的序列,你可以选择你想要在一个数组发送代码序列中通过,这将调用that.createIRRC()
对于每个连续的代码:
function sendSequence(cntr, data, delay) {
// create post_data for next code to send in the sequence
let post_data = that.createIRRC(data[cntr]);
that.makeHttpRequest(onError, function() {
// if we haven't done this limit times yet, then set a timer and
// run it again after one second
if (++cntr < data.length) {
setTimeout(function() {
sendSequence(cntr, data, delay);
}, delay);
} else {
onSuccess();
}
}, "", post_data,false);
}
// define the codes
// this should probably be done once at a higher level where you can define
// all the codes you might want to send so you can reference them by a meaningful
// name rather than an obscure string
let codes = {
right: "AAAAAQAAAAEAAAAzAw==",
down: "AAAAAQAAAAEAAABlAw==",
select: "AAAAAQAAAAEAAABlAw==",
options: "AAAAAgAAAJcAAAA2Aw==",
hdmi2: "AAAAAgAAABoAAABbAw==",
hdmi3: "AAAAAgAAABoAAABcAw=="
}
// create sequence of codes to be sent
let dataSequence = [
codes.hdmi2, codes.options,
codes.down, codes.down, codes.down, codes.down, codes.down, codes.down, codes.down,
codes.right,
codes.down, codes.down, codes.down, codes.down,
codes.select, codes.hdmi3
];
// start the process with initial cnt of 0 and
// send the sequence of data to be sent and
// with a one second delay between commands
sendSequence(0, dataSequence, 1000);
请注意,这里'onError'和'onSuccess'将被多次调用 – arboreal84
@ arboreal84 - 不,“onError'只会被调用一次。循环在调用onError之后停止 - 这是故意设计的。 'onSuccess'会被多次调用,因为这似乎是OP所需要的,否则OP将无法从每次调用中获取响应。 – jfriend00
我在哪里放置createIRRC行? - 我一直在尝试这两个代码,并通过@ arboreal84,我无法得到任何工作:(我试图发送代码序列(选项/向下x 6 /右/下/选择/ HDMI3 ),以选择一个特定的功能(没有谨慎的代码可用)。如果我使用多个“that.makeHttpRequest(onError,onSucces,”,“post_data,false);”行有效*有时*,其他人会感到困惑。 – Jason
var times = 0;
var ivl = setInterval(function() {
var post_data = that.createIRRC("AAAAAQAAAAEAAAB1Aw==");
that.makeHttpRequest(onError, onSucces, "", post_data, false)
if (++times === 7) {
clearInterval(ivl);
}
}, 1000);
向我们展示'setTimeout'的尝试,请 – Bergi
