问题描述
我在我的react应用中实现了http代理中间件,我的setupProxy.js路径无法识别。下面是我的代码,如果我做错任何事情,请告诉我。
应用程序组件
class App extends React.Component {
test = () => {
// I dont have any thing which is running in "/api"
// Simply called fetch with "/api" because setupPorxy.js is looking my request or not
fetch("/api")
.then(res => {
alert('test pri')
console.log('res',res)
})
}
render() {
return (
<div className="App">
<button onClick={this.test}>Test</button>
</div>
);
}
}
setupProxy.js
const { createProxyMiddleware } = require('http-proxy-middleware');
\\ I dont have any thing running on localhost 5000,want to check the request is modified or not
module.exports = (app) => {
app.use(createProxyMiddleware('/api',{ target: 'http://localhost:5000',changeOrigin: true }));
}
But ended with 404 not found in browser console like http://localhost:3000/api (404 not found)
解决方法
通过您的代码,我可以看到您使用过create-react-app。您尚未显示package.json。您添加了代理吗?我想您可能已经错过了。
package.json
{
....
"proxy": "http://localhost:5000",}
