redux-saga 中 channel 的原理是怎样的?

  FaiChou · FaiChou · 5 分钟前 · 3 次点击

摊牌了, 源码没看懂. 有个地方想请教, 例子:

function* watchAndDo() {
  const channel = yield actionChannel('TEST');
  while (true) {
    const payload = yield take(channel);
    yield call(Api, payload);
  }
}

这个例子中, 假如一起来了 10 个 TEST, 则会一个一个执行. 那么这里 channel 是如何做到等待循环里的 block 结束再派发下一个动作的?

目前了解到: 创建 channel 后, dispatch 的消息会加入到 buffer 中, buffer 是一个数组.
