IT技术 - React 全局错误处理程序不适用于异步 componentDidMount。尝试了 componentDidCatch 和 window.onerror - 吾爱随笔录

我有以下代码index.tsx：

window.onerror = function(msg, url, line, col, error) {
   debugger;
   // Note that col & error are new to the HTML 5 spec and may not be 
   // supported in every browser.  It worked for me in Chrome.
   var extra = !col ? '' : '\ncolumn: ' + col;
   extra += !error ? '' : '\nerror: ' + error;

   // You can view the information in an alert to see things working like this:
   alert("Error: " + msg + "\nurl: " + url + "\nline: " + line + extra);

   // TODO: Report this error via ajax so you can keep track
   //       of what pages have JS issues

   var suppressErrorAlert = true;
   // If you return true, then error alerts (like in older versions of 
   // Internet Explorer) will be suppressed.
   return suppressErrorAlert;
};

如果我在另一个组件中抛出这样的错误，我会按预期捕获它：

componentDidMount() {
    throw new Error();
}

如果像这样抛出：

async componentDidMount() {
    throw new Error();
}

错误未被捕获并Unhandled Rejection (Error):显示。

然后我尝试创建一个 React 全局错误边界。

import React, { ErrorInfo } from 'react';

interface IProps {

}

interface IState {
    hasError: boolean
}

class ErrorBoundary extends React.PureComponent<IProps, IState> {
    constructor(props: IProps) {
        super(props);
        this.state = { hasError: false };
    }

    componentDidCatch(error: Error, info: ErrorInfo) {
        // Display fallback UI
        debugger;
        console.warn(error);
        console.warn(info);

        this.setState({ hasError: true });
        // You can also log the error to an error reporting service
        //logErrorToMyService(error, info);
    }

    render() {
        if (this.state.hasError) {
            // You can render any custom fallback UI
            return <h1>Something went wrong.</h1>;
        }
        return this.props.children;
    }
}

export default ErrorBoundary

索引.tsx：

<React.StrictMode>
    <Provider store={store}>
        <ConnectedIntlProvider>
            <Router>
                <ErrorBoundary>
                    <App />
                </ErrorBoundary>
            </Router>
        </ConnectedIntlProvider>
    </Provider>
</React.StrictMode>,

然而，效果是一样的，async componentDidMount没有被发现，但它按预期工作。

我发现这个线程提到了这个问题，但没有真正的解决方案。

如何在 React 中创建一个真正捕获所有内容的全局错误处理程序？
