javascript - 在 redux-saga 中等待

Question

我想在 saga 中引入延迟(使用 redux-saga)。

我该怎么做？

如果redux-saga提供了API，我也很想知道如何手动实现。

function* save({ payload }) {
    yield put(pending());
    // I want to simply wait (non-blocking) here for say 2 seconds
    yield put(complete());
}

Redux-sagas 有 a special effect为此:

delay(ms, [val])

Returns a Promise that will resolve after ms milliseconds with val.

例子:

import { delay, call } from 'redux-saga/effects'

function* someSaga(input) {
  yield put(someAction())
  yield delay(500)
  yield put(anotherAction())
}
