无法使用 yield all Redux Saga 发送请求

Question

我有两个数组：listingMapIds 和 selectedFeePayload。而我想做的是为每个listingMapId发送selectedFee的数量，也就是说，如果selectedFeePayload包含两个对象，那么每个listingMapId发送两个请求。这是我的代码摘录：

if (selectedFeePayload.length > 0) {
      const response = yield all(listingMapIds.map(listingMapId => selectedFeePayload.map(fee =>
        call(addListingOptionalFeeRequest, { listingMapId, payload: fee }))));

      console.log(response);
    }

但没有发送请求请帮助

Answer 1

我不认为all 效果可以处理嵌套数组。先尝试展平数组。

if (selectedFeePayload.length > 0) {
    const requests = listingMapIds.map(listingMapId => selectedFeePayload.map(fee =>
        call(addListingOptionalFeeRequest, { listingMapId, payload: fee })))
    const response = yield all(requests.flat());

    console.log(response);
}
