Mah*_*aji 20 reactjs redux redux-form
我在 React 项目中使用 redux 表单,这是已初始化 redux 表单的应用程序组件:
import { Field, reduxForm } from 'redux-form';
const onSubmit = (values) => {
alert(JSON.stringify(values));
};
function App(props) {
return (
<div className="App">
<form onSubmit={props.handleSubmit}>
<div>
<label htmlFor="firstName">First Name</label>
<Field name="firstName" component="input" type="text" />
</div>
<div>
<label htmlFor="lastName">Last Name</label>
<Field name="lastName" component="input" type="text" />
</div>
<div>
<label htmlFor="email">Email</label>
<Field name="email" component="input" type="email" />
</div>
<button type="submit">Submit</button>
</form>
{props.number}
<button onClick={() => props.callAction()} />
</div>
);
}
App = reduxForm({
form: 'contact',
onSubmit
})(App);

但我在控制台中收到此错误,该错误来自反应严格模式:
Using UNSAFE_componentWillReceiveProps in strict mode is not recommended and may indicate bugs in your code.
* Move data fetching code or side effects to componentDidUpdate.
* If you're updating state whenever props change, refactor your code to use memoization techniques or move it to static getDerivedStateFromProps. Learn more at:state
Please update the following components: Field, Form(App)

我该如何修复这个错误?

就我而言,我认为问题是由于头盔造成的"react-helmet"
解决我使用的问题react-helmet-async并将所有内容包装在<HelmetProvider>jsx return 下
下面是示例代码
有问题的代码
import React from "react";
import { Helmet } from "react-helmet";
function XYZ(){
return(
<div>
<Helmet>
<meta />
</Helmet>
<p>...</p>
</div>
)
}

修复代码
import React from "react";
import { Helmet, HelmetProvider } from 'react-helmet-async';
function XYZ(){
return(
<HelmetProvider>
<div>
<Helmet>
<meta />
</Helmet>
<p>...</p>
</div>
</HelmetProvider>
)
}
