[英]Vue.js error "app' is assigned a value but never used no-unused-vars
[英]React error “./src/App.js Line 7: 'APIKEY' is assigned a value but never used no-unused-vars”
我從教程中使用React.js創建了一個天氣應用,現在我陷入了困境,無法解決此錯誤“。/src/App.js第7行:'APIKEY'被分配了一個值,但從未使用過no-unused-vars “ 。 如何解決此錯誤?
下面是我的代碼:
import React from 'react';
import './App.css';
import Titles from './components/titles';
import Form from './components/form';
import Weather from './components/weather';
const APIKEY = "0bfdbb5c40aa44b13478951b236a0625";
class WeatherApp extends React.Component {
getWeather = async (e) => {
e.preventDefault();
const api_call= await fetch('http://api.openweathermap.org/data/2.5/forecast?id=524901&APPID={APIKEY}');
const response = await api_call.json();
console.log(response);
}
render() {
return (
<div>
<Titles/>
<Form loadWeather={this.getWeather} />
<Weather/>
</div>
)
}
}
export default WeatherApp;
您可以使用模板文字。 因此:
const api_call= await fetch(`http://api.openweathermap.org/data/2.5/forecast?id=524901&APPID=${APIKEY}`);
帶有背景色和$符號。
