reactjs - 在 createError 中 react 原生错误 : node_modules/axios/lib/core/createError. js:16:24

Question

我写了这个函数

fetchWeather(){
    axios.get(`http://api.openweathermap.org/data/2.5/forecast/daily?q=${this.state.city},uk&APPID=3a31a881817a041a63eac1c1bbbba705`)
    .then((response)=>{
      this.setState({report:response.data})
    }).catch((error)=>console.log(error))
  }

并收到此错误:

node_modules/axios/lib/core/createError.js:16:24 in createError - node_modules/axios/lib/core/settle.js:19:6 in settle - ... 10 more stack frames from framework internals

Answer 1

根据 axios GitHub代码(axios/lib/core/settle.js):

reject(createError(
      'Request failed with status code ' + response.status,
      response.config,
      null,
      response.request,
      response
    ));

由于状态代码无效(很可能是 HTML 401)，响应被拒绝。检查您的 api key 是否仍然有效，或在 postman 中测试您的 URL。

编辑:以下是基于新 URL 的工作代码片段

class Hello extends React.Component {
	constructor() {
  	super();
    this.state={
    	report: null,
    };
  }

  componentDidMount() {
  axios.get(`https://api.openweathermap.org/data/2.5/weather?q=London,uk&APPID=3a31a881817a041a63eac1c1bbbba705`)
  .then((response)=>{
  	this.setState({report:response.data});
    console.log(response.data);
  }).catch((error)=>console.log(error))
  }
  
  render() {
    return <div>Report: {JSON.stringify(this.state.report)}</div>;
  }
  
}

ReactDOM.render(
  <Hello />,
  document.getElementById('container')
);
