我正在使用 react、redux 和 axios 制作此应用程序，其中一个组件显示完整的地址列表，下一个组件显示一个选定的地址。地址列表组件工作正常，但单个视图组件出现问题，返回以下错误：

在涉及 changeSelected->address 的 redux 链中的某个地方，发送了一个承诺而不是承诺的结果。我很难确定这一点，因为我对多地址视图 fetchAddresses-> 使用了类似的结构地址工作正常。

这是我的反应组件

const Card = async (props) => {
    const { changeSelected,address } = props
    console.log(address)

    useEffect(() => {
            changeSelected(1);
    },[changeSelected(1)])

    if (!address){
        return <h1>No results</h1>
    } else {
        return (
            <React.Fragment>
              <CssBaseline />
              <Container maxWidth="sm">
                <Typography component="div" style={{ backgroundColor: '#cfe8fc', height: '100vh' }} >   
                    <Typography variant="h6" >{address.body}</Typography>
                </Typography>
              </Container>
            </React.Fragment>
          );
    }

}

Card.propTypes = {
    changeSelected: PropTypes.func.isRequired,
    address: PropTypes.object.isRequired,
}

const mapStateToProps = state => ({
    address: state.address.address,

})


export default connect(mapStateToProps, {changeSelected})(Card) 

这是我分派的动作

export const changeSelected = (postData) => dispatch => {
    console.log(postData)
    axios.get(`https://jsonplaceholder.typicode.com/posts/${postData}`)
        .then(addresses => {
            console.log(addresses)
            dispatch({
            type: CHANGE_SELECTED,
            payload: addresses.data
        })}).catch(err => {
            dispatch({
                //if there's an error, send the user a card saying so
                type: CHANGE_SELECTED,
                payload: [{id:0,nickName:'error',content:'please contact cutomer service at 010-314-1150'}]
            })
            console.log(err)
        })
}

这是我的减速器

//create initial state
const initialState = {
    addresses: [],
    address:{}
}


export default (state = initialState, action) => {
    switch(action.type) {
        case FETCH_ADDRESSES:
            return{
                ...state,
                addresses: action.payload
            }
        case CHANGE_SELECTED:
            return{
                address: action.payload
            }
        default:
            return state
    }
}

响应正在到达减速器，但在返回承诺之前调用了错误消息。
