javascript - react 在container里已经注入数据，为何在props没有？

Question

//container
import { connect } from 'react-redux'
import FollowerGroupNewForm from '../../components/_forms/FollowerGroupNewForm'
import { getTags } from '../../actions/tags'

const mapDispatchToProps = dispatch => {
  return ({
    getTags: () => dispatch(getTags())
  })
}

const mapStateToProps = state => {
  return ({
    authInfo: state.authInfo,
    hi: 'hi'
  })
}

export default connect(mapStateToProps, mapDispatchToProps)(FollowerGroupNewForm)

//component
  componentDidMount () {
    const { props: { getTags } } = this
    console.log(this.props)
    getTags().then(data => {
      const tags = data.map(tag => ({
        value: tag.name,
        label: tag.name
      }))

      this.setState({ tags: tags })
    })
  }

getTags 为 undefined， 没找到原因，求助！

试试看这样：

import {bindActionCreators} from 'redux'
const mapDispatchToProps = dispatch => {
  return ({
    getTags: () => bindActionCreators(getTags,dispatch)
  })
}
