Dva中在effects中获取state的值
首先，看官网给出effects中的例子 effects详情见
it('put multi effects in order', done => { const app = create(); app.model({ namespace: 'counter', state: { count: 0, resolveCount: 0, }, reducers: { dump(state, { payload }) { return { ...state, ...payload, }; }, }, effects: { *changeCountDelay({ payload }, { put, call }) { yield call(delay, 200); yield put({ type: 'dump', payload: { count: payload } }); }, *process({ payload }, { put, select }) { yield put.resolve({ type: 'changeCountDelay', payload }); const count = yield select(state => state.counter.count); yield put({ type: 'dump', payload: { resolveCount: count } }); }, }, });
从这个例子我们可以看出
在effects中想要获得state中的值，需要解构出select方法
用法具体如下
const xxx = yield select( state => state.namespcae(你自己起的命名空间).想要取得的值)
运用
export default { namespace: 'CWL_UserSettingsModel', state: { pagination:{}, userData: [], userInfo: {}, }, effects: { *addUser({payload},{call,put,select}){ console.log('addUser',payload); const pagination = yield select(state => state.CWL_UserSettingsModel.pagination) const response = yield call (UserSettingService.addUser,payload) const {code} = response; if (response.code === 0) { message.success('新增用户成功'); yield put({ type: 'getList', payload: pagination, }); } else{ message.error("新增用户失败"); } } },
通过这句话取到了state中pagination的值
const pagination = yield select(state => state.CWL_UserSettingsModel.pagination)
另外，如果你想在model中取到另一个model中state值，我们可以举一反三一下，只要在后面添加上你想取的model的namespace的值即可
比如：我想一个model中取到globalModel中的值
const globalModelData = yield select((state) => state.globalModel);
这样，我们就可以在一个Model中取到globalModel中的state值了
