Javascript 使用 ReduxToolkit 的 createAsyncThunk 返回一个值

是的，您可以返回rejectWithValue并返回错误.

示例:

exp或t const newClient = createAsyncThunk(
  'clients/newClient', 
  async ({ name, email, tel }, { getState, dispatch, rejectWithValue }) => {
    try {
      if (name && email && tel) {
        const res = await $.post(
          `${URL}/clients/newClient`,
          { name, email, tel }
        );
        dispatch(slice.actions.NewClient({
          name,
          email,
          tel,
          _id: res.data.data._id
        }));
        // return value success;
      } else {
        // return value
      }
    } catch(err或) { 
      return rejectWithValue(err或); // <-- return rejection w/err或 here
    }
  }
);

然后，UI应该解开已解析的Promise.

const setNewClient = async () => {
  try {
    const res = await dispatch(newClient({ name, email, tel })).unwrap();
    console.log(res);
  } catch(err或) {
    console.log(err或);
  }
}

或

const setNewClient = () => {
  dispatch(newClient({ name, email, tel })).unwrap()
    .then(res => console.log(res))
    .catch(err => console.log(err));
};
