reactjs - 为什么不链接调度 Redux-Thunk

Question

为什么不链接调度 Redux Thunk？仅工作第一次调度和第二次调度不起作用。

店铺：

const store = createStore(reducers, loadState(), applyMiddleware(thunk));

行动：

export function doSomething(name) {
    return function (dispatch) {
        dispatch({
            type: 'USERNAME',
            payload: name
        })
        dispatch({
            type: 'OTHER_TYPE',
            payload: 'text'
        })

         return true;
    }
}

编辑 它的工作：

return Promise.all([
        dispatch({
            type: 'USERNAME',
            payload: name
        }),
        dispatch({
            type: 'OTHER_TYPE',
            payload: 'text'
        })
    ])

从文档：

    // We can dispatch both plain object actions and other thunks,
    // which lets us compose the asynchronous actions in a single flow.

    return dispatch(
      makeASandwichWithSecretSauce('My Grandma')
    ).then(() =>
      Promise.all([
        dispatch(makeASandwichWithSecretSauce('Me')),
        dispatch(makeASandwichWithSecretSauce('My wife'))
      ])
    ).then(() =>
      dispatch(makeASandwichWithSecretSauce('Our kids'))
    ).then(() =>
      dispatch(getState().myMoney > 42 ?
        withdrawMoney(42) :
        apologize('Me', 'The Sandwich Shop')
      )
    );

但由于这些原因，我建议使用redux-saga而不是 redux-thunk。
