我正在测试 react路由器和我创建了 2 个虚拟组件。主路径工作正常，但是当我尝试转到该/second路径时，出现以下错误：
拒绝执行内联脚本，因为它违反了以下内容安全策略指令：“default-src 'self'”。启用内联执行需要“unsafe-inline”关键字、哈希（“sha256-GBZpdGedoBaq6YBC2+5oO7Dc8WC1XJ5EUI5Md05Lls8='）或随机数（“nonce-...”）。还要注意 'script-src' 没有明确设置，所以 'default-src' 用作后备。
第一个组件
import React, { Component} from 'react'
import ReactDOM from 'react-dom'
const First = () => (<div>Hello 1</div>);
export default First;
第二个组件
import React, { Component} from 'react'
import ReactDOM from 'react-dom'
const Second = () => (<div>Hello 2</div>);
export default Second;
和布局组件
import React, { Component} from 'react';
import ReactDOM from 'react-dom';
import {
BrowserRouter as Router,
Route,
Link
} from 'react-router-dom'
import First from './first.js';
import Second from './second.js';
class Layout extends Component {
constructor () {
super()
this.state = {
};
}
render(){
return (
<Router>
<div>
<Route exact path="/" component={First}/>
<Route path="/about" component={Second}/>
</div>
</Router>
);
}
}
const app = document.getElementById('app')
ReactDOM.render(<Layout />, app)
