[英]I am getting TypeError: this.props.function is not a function while fetching from an api
我正在尝试从 api 获取数据,但出现错误: TypeError: this.props.getPeople is not a function,虽然通过代码一切看起来都不错,如下所示:
人员组件.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);
动作/ 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 });
}
}
减速器/ 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
感谢@Brian Thompson
,我将People
组件作为名称导入,而它作为默认导出。它已修复。
