我正在尝试设置一个排队系统,以便重复post请求
n
时间,间隔
i
到目前为止我已经有了这个,感觉有点凌乱和粗糙。我觉得我可能错过了一个简单得多的解决方案,但似乎什么也找不到:
// this is mocked to avoid a wall of code
const postData = (url, data) => Promise.resolve(true);
// this is mocked to avoid a wall of code
const resIsFailed = () => true;
const requestChain = ({
url,
data,
maxRequests,
requestTimeout,
currentRequest = 0,
requestIncrement = increment => increment,
}) => {
// exit condition
if (currentRequest >= maxRequests || (!maxRequests)) {
console.log('Too many failed requests');
return Promise.reject(new Error('Too many attempts'));
}
// post the data, if it fails, try again
postData(
url,
data,
).then(res => {
if (resIsFailed(res)) {
console.log('Failed response: ');
console.dir(res);
setTimeout(() => {
requestChain({
url,
data,
maxRequests,
requestTimeout: requestIncrement(requestTimeout),
currentRequest: currentRequest + 1,
requestIncrement,
});
}, requestTimeout);
} else {
return Promise.resolve(res);
}
});
}
requestChain({
url: 'fail',
data: {},
maxRequests: 5,
requestTimeout: 100,
})
