Question

我正在使用redux-saga。我的传奇实现只需要调用一次就可以调用两次。

我的传奇：

export function* api(parms) {

    try {

        //when parms hasnt a uv key, it's a local calling
        if(!parms['uv']){

            yield put(publish(parms,parms['action']));
            return
        }

        //to check user_id if the user is login - from local storage
        if(isLogin()){

            if(!parms['user_id'])
                parms['user_id'] = getData('USER').user_id;
        }

        //to create token
        parms['tok']    = getToken(parms,parms['uv'])
        parms['time']   = todayForamted;


        var formData = new FormData()
        for ( var key in parms ) {
            formData.append(key, parms[key]);
        }
        var requestOptions = {}
        requestOptions.body = formData


        // Call our request helper (see 'utils/request')
        const response = yield call(request, baseUrl+parms['uv'], requestOptions);


        yield put(done(response,parms['uv']));
    } catch (err) {
        console.log('error',err)
        yield put(error(err));

    }
}



/**
 * Root saga manages watcher lifecycle
 */
export default function* watcherApi() {
    yield takeLatest([Uva2,Uva3,Uva8,Uva10,Uva11,Uva19,Uva20,Uva46,current_tr], api);

}

[Uva2,Uva3,Uva8,Uva10,Uva11,Uva19,Uva20,Uva46,current_tr]是我的唯一键。

我的动作：

export function getFinanceOfUsersByUserId(parms) {
  return {
    type: Uva19,
    ...parms,
  };
}


export function done(res,uv) {
  return {
    type: DONE,
    uv:uv,
    ...res,
  };
}

export function error(error) {
  return {
    type: ERROR,
    error,
  };
}

我的组件连接：

const mapStateToProps = (state, ownProps) => {

    var responsiveObj = state.get('api').get('responsiveObj')

    if(!responsiveObj)
        return {}
     else
        return {'responsiveObj':responsiveObj}   

  }

const withConnect = connect(
    mapStateToProps,
   // mapDispatchToProps,
);


const withReducer = injectReducer({ key: 'api', 'reducer':apiReducer });
const withSaga = injectSaga({ key: 'api', saga });

export default compose(
    withReducer,
    withSaga,
    withConnect,
)(Index);

在我的componentDidMount函数中：

this.props.dispatch(getFinanceOfUsersByUserId({'uv':'Uva19'}))

我所有的肌动蛋白都叫了两次！
