Force Request

Forced request refers to a mechanism that bypasses the cache check and triggers a request. It is useful when the latest data needs to be obtained under certain conditions.

Force request with method

Force request by calling the send function of the method instance, and passing true.

const response = await alovaInstance.Get('/api/user').send(true);

Force request in useHook

Among the three core hooks of useRequest/useWatcher/useFetcher, force request parameters are supported.

// useRequest
useRequest(todoListGetter, {
  force: true
});

// useWatcher
useWatcher(todoListGetter, [page], {
  force: true
});

// useFetcher
useFetcher({
  force: true
});

Dynamically set force value

In actual situations, we often need to set whether to force the request to be sent based on different situations. In this case, force can be set to a function, which will also receive parameters passed in from the send function. Please read the receive params for details

useRequest(todoListGetter, {
  force: isForce => {
    return isForce;
  }
});

// useWatcher
useWatcher(todoListGetter, [page], {
  force: isForce => {
    return isForce;
  }
});

// useFetcher
useFetcher({
  force: isForce => {
    return isForce;
  }
});

useFetcher is a useHook for data fetching, which will be discussed in the Data Fetching chapter later.
