function createThunkMiddleware(extraArgument) { return function thunk(store) { return function (next) { return function (action) { // 从store中结构出dispatch, getState const { dispatch, getState } = store; // 如果action是函数,将它拿出来运行,参数就是dispatch和getState if (typeof action === 'function') { return action(dispatch, getState, extraArgument); // 这里还可以传入extraArgument } // 否则按照普通action处理 let result = next(action); return result } } } } const thunk = createThunkMiddleware(); thunk.withExtraArgument = createThunkMiddleware; export default thunk;
