Question

我是redux-sagas的新手，我仍然试图了解他们的工作方式。我试图将一个redux-saga函数绑定到我的一个组件上，然后发出一个API请求，然后用响应中的数据调度一个动作。在根据文档尝试将调度传递给我的传奇函数参数时，我收到了调度错误的定义。这是我的设置：

缩略图容器

import React, { PureComponent } from 'react';
import { connect } from 'react-redux';
import { bindActionCreators } from 'redux';
import { getThumbnails } from '../../../containers/search/sagas';
import createReducer from './reducers';

class ThumbnailsContainer extends PureComponent {
  constructor(props) {
    super(props);
  }

  componentWillMount() {
    this.props.getThumbnails()
  }

  render() {
    return (
      <div>My Container</div>
    )
  }
}

function mapDispatchToProps(dispatch) {
  return {
    getThumbnails: bindActionCreators(getThumbnails, dispatch)
  }
}


export default connect(null, mapDispatchToProps)(ThumbnailsContainer);

Sagas.js

export function* getThumbnails(dispatch) {

  console.log(dispatch)

  yield fetch('myAPIurl', {
    method: 'post',
    headers: {
      'Accept': 'application/json, text/plain, */*',
      'Content-Type': 'application/json'
    },
    body: {}
  }).then(res=>res.json())
    .then(res => {
      console.log(JSON.parse(res.data))
    });
}

rootsagas.js

import { all, fork } from 'redux-saga/effects';

export default function* rootSaga() {
  yield all([
    fork(getThumbnails)
  ]);
}

Stores.js

import { applyMiddleware, compose, createStore } from 'redux';
import createSagaMiddleware from 'redux-saga';
import rootSaga from './rootsagas';

const sagaMiddleware = createSagaMiddleware();
const apolloMiddleware = apolloClient.middleware();

export default function configureStore(initialState = {}, history) {
  const middlewares = [
    sagaMiddleware
  ];
})

store.runSaga = sagaMiddleware.run(rootSaga);
store.asyncReducers = {}; // Async reducer registry

const store = createStore(createReducer(), applyMiddleware(...middlewares));

store.runSaga = sagaMiddleware.run(rootSaga);
store.asyncReducers = {}; // Async reducer registry

return store;

我想做的是在我获得API响应后发出一个动作，但似乎无法掌握调度功能。无法在他们的文档中看到我哪里出错了？

不确定是否正确。尝试使用put中的redux-saga。如下所示

import { put } from 'redux-saga/effects';

function* yourGenerator() {
  /*Your code*/
  yield put({ type: 'YOUR_ACTION', YOUR_PAYLOAD });
}

使用saga here了解有关调度操作的详情。
