我的重击动作似乎并没有贯穿其核心逻辑。我高举了componentDidMount
的重击动作,但这并不会导致它运行:const response = await findOne(id)
。
另外,我认为如果使用redux-thunk,则不需要显式传递dispatch作为对mapDispatchToProps的支持,我认为我的thunk设置方式是该thunk已经可以使用dispatch?而且我还使用了其他类似的操作,效果很好,为什么不这样做呢?
重击动作
export function fetchCompany(id) {
return async (dispatch) => {
try {
const response = await findOne(id)
if(response && response.body) {
const company = response.body
dispatch(companyReceived(company))
}
} catch(err) {
console.log("failed request in authenticate thunk action")
console.log(`error details: ${err.status} /n ${err}`)
}
}
}
容器
......
import { fetchCompany } from '../../client/actions/company/CompanyAsyncActions'
class InterviewContainer extends Component {
async componentDidMount() {
await fetchCompany(this.props.params.companyId)
}
render(){
return (this.props.company && <Interview className='ft-interview' company={this.props.company} />)
}
}
const mapStateToProps = state => ({
company: state.company.company
})
const mapDispatchToProps = {
fetchCompany: fetchCompany
}
export default connect(mapStateToProps, mapDispatchToProps)(InterviewContainer)
过去,我没有通过(dispatch)作为mapDispatchToProps的道具,并且效果很好。但是我看到其他所有人都在这样做。如果我不这样做,过去的代码将如何工作?为什么在上面的示例中这一次不起作用?
看一下另一个异步动作重排容器和调用示例,这完全可以正常工作,我在另一个容器中以相同的方式调用它
容器
class HomePageContainer extends Component {
constructor(){
super()
}
async componentDidMount() {
await this.props.fetchFeaturedCompanies()
await this.props.fetchCompanies()
await this.props.fetchCountries()
}
render(){
return (<HomePage className='ft-homepage'
featuredCompanies={this.props.featuredCompanies}
countries={this.props.countries}
companies={this.props.companies}
/>)
}
}
const mapStateToProps = state => ({
countries: state.country.countries,
companies: state.company.companies,
featuredCompanies: state.company.featuredCompanies
})
const mapDispatchToProps = {
fetchCountries: fetchCountries,
fetchCompanies: fetchCompanies,
fetchFeaturedCompanies: fetchFeaturedCompanies
}
export default connect(mapStateToProps, mapDispatchToProps)(HomePageContainer)
重击动作
export function fetchCompanies() {
return async (dispatch, getState) => {
const response = await find()
if(response && response.body) {
const companies = response.body
dispatch(companiesReceived(companies))
}
}
}
最佳答案
在componentDidMount
的InterviewContainer
中,您不小心调用了导入的fetchCompany
,而不是this.props.fetchCompany
。
