为什么我的控制台没有记录我的代码？

Question

Can you help with this issue - I am unable to see a log in the console. I was trying to log/view the data in the console with the codes below, but when i run it nothing shows. I think I have it correctly, but I might be wrong. Can you help?

 import React, { Component } from 'react' import { Container, Row, Col } from 'bootstrap-4-react'; import News from '../Articles/News'; import Post from '../Posts/Post/Post'; import axios from 'axios'; export default class Body extends Component { state = { title: "", description: "", urlToImage: "", newsPost: [] } componentDidMount = () => { this.getNews(); } getNews = async() => { const news = await axios.get(`https://newsapi.org/v2/top-headlines?sources=techcrunch&apiKey=${process.env.REACT_APP_NEWS_ARTICLE_API}`).then((res) => { const data = res.data; this.setState = ({newsPost: data}); console.log("newsPost Recieved"); //cannot see this in the console. }) } render() { return ( <Container id="bodycontainer" className="container"> <Row className="rowstyles"> <Col className="newscolumn" col="12 sm-6 md-8"> <Post /> </Col> <Col className="contentcolumn" col="6 md-3"> <div className="centersources">Sources</div> </Col> </Row> </Container> ) } }

There's a lot of possibilities here since you're not providing the full code and we can't even debug this. So I'll just mention a couple of suggestions:

• this.setState = ({newsPost: data}) should be this.setState({newsPost: data}) .
• Make sure that the API returns a proper answer.
• Make sure process.env.REACT_APP_NEWS_ARTICLE_API is returning the correct value as well.
• Place a console.log() outside/before the axios promise, make sure the getNews method is being called.
