如何将值传递给rootSaga？

Question

我现在正在从redux-saga练习Official Docs。 我对example有疑问

sagas.js

import {delay} from 'redux-saga';
import {all, call, put, takeEvery} from 'redux-saga/effects';
import axios from 'axios';

const API_ROOT = 'http://localhost:8000';

const postAPIGetToken = ({username, password}) => {
  const request = axios({
    method: 'post',
    url: `${API_ROOT}/api-token-auth/`,
    data: {
      username,
      password
    }
  });
  return request();
};


export function* shootAuth(action) {
  const res = yield call(postAPIGetToken, action.payload);
  yield put({
    type: 'GOT_RESPONSE',
    payload: res
  })
}


// single entry point to start all Sagas at once
export default function* rootSaga(values) {
  const {username, password} = values;
  yield all([
    helloSaga(),
    watchIncrementAsync(),
    shootAuth()
  ])
}

main.js

import "babel-polyfill"

import React from 'react'
import ReactDOM from 'react-dom'
import {createStore ,applyMiddleware} from 'redux'
import createSagaMiddleware from 'redux-saga';

import Counter from './Counter'
import reducer from './reducers'
import {helloSaga} from "./sagas";
import rootSaga from "./sagas";
const sagaMiddleWare = createSagaMiddleware()

const store = createStore(
  reducer,
  applyMiddleware(sagaMiddleWare)
);
sagaMiddleWare.run(rootSaga);

const action = (type, payload={}) => store.dispatch({type, payload})

function render() {
  ReactDOM.render(
    <Counter
      value={store.getState()}
      onIncrement={() => action('INCREMENT')}
      onDecrement={() => action('DECREMENT')}
      onIncrementAsync={() => action('INCREMENT_ASYNC')}
      shootToken={()=>action('SHOOT_TOKEN',
        {
          username: 'tonyod',
          password: 'mbx12345'
        })}
    />,
    document.getElementById('root')
  )
}

render()
store.subscribe(render)

在我的工作项目中。我的react有redux-form，能够通过username/password。这是我的方法。

onSubmit(values) {
    const {username, password} = values;
    this.props.onSubmitClick(values, REQUEST);
  }

我有username和password形式。我想把它们传递给saga。但rootSaga没有争论。我该如何供应呢？

Answer 1

只需将其他参数传递给sagaMiddleware.run调用，如下所示：

sagaMiddleWare.run(rootSaga, value);

Answer 2

感谢来自panigrah gitter的chat-room/reactjs。

你正在使用sagas登录？ Sagas将听取调度方法。因此，在您的操作处理程序中，您将使用有效内容中的用户名和密码参数调度LOGIN之类的操作。在saga中，您可以侦听要调度的LOGIN操作，并从操作有效负载中获取用户名和密码。

因此我采用了错误的实施方式。我模拟单个按钮将发出action与type和payload是用户名和密码。

我错过的是：

1 - 我必须使用store.dispatch(action)

<Counter
      value={store.getState()}
      shootToken={()=>store.dispatch(
        {
          type:'SHOOT_ASYNC',
          payload: {
            username: 'tonyod',
            password: '12345'
          }
        })
      }
/>

2 - 我必须在takeEvery或takeLastest观看应用程序中的actions。

const postAPIGetToken = (values) => {
  const {username, password} = values;
  return axios.post(`${API_ROOT}/api-token-auth/`,
    {
      username,
      password
    });
};      

export function* shootAuth(action) {
  const res = yield call(postAPIGetToken, action.payload);
  yield put({
    type: 'GOT_RESPONSE',
    payload: res
  })
}   

export function* watchShootAuth() {
  yield takeEvery('SHOOT_ASYNC', shootAuth)
}

// single entry point to start all Sagas at once
export default function* rootSaga() {
  yield all([
    helloSaga(),
    watchIncrementAsync(),
    watchShootAuth()
  ])
}

PS。：Ctrl + K不适用于整个2号代码。它部分适用于它们。
