[英]I am getting TypeError: this.props.function is not a function while fetching from an api
我正在嘗試從 api 獲取數據,但出現錯誤: TypeError: this.props.getPeople is not a function,雖然通過代碼一切看起來都不錯,如下所示:
人員組件.js
import React, { Component } from 'react';
import './people-component-styles.css';
import { Container, Row, Col, Card } from 'react-bootstrap';
import { connect } from 'react-redux';
import { getPeople } from '../../actions/index'
import 'react-lazy-load-image-component/src/effects/blur.css';
import 'animate.css/animate.min.css';
export class People extends Component {
componentDidMount() {
// console.log(this.props);
this.props.getPeople();
}
render() {
// console.log(this.props);
return (
<Row className='main'>
hello!
</Row>
);
}
}
const mapStateToProps = state => ({
people: state.people
})
const mapDispatchToProps = dispatch => ({
getPeople: () => dispatch(getPeople())
})
export default connect(
mapStateToProps,
mapDispatchToProps
)(People);
動作/ index.js
export const getPeople = () => {
console.log("yes");
return async dispatch => {
const response = await fetch('https://dma.com.eg/api.php?action=getPeople', {
method: 'GET'
})
const json = await response.json();
dispatch({ type: "GET_PEOPLE", payload: json });
}
}
減速器/ index.js
const INITIAL_STATE = {
people: []
}
const rootReducer = (state = INITIAL_STATE, action) => {
switch (action.type) {
case "GET_PEOPLE":
return ({
...state,
people: state.people.concat(action.payload)
})
default:
return state;
}
};
export default rootReducer
感謝@Brian Thompson
,我將People
組件作為名稱導入,而它作為默認導出。它已修復。
