socket长连接运行在http协议上时，浏览器报出错误。在使用Apache反向代理，React的serviceWorker会报出错误，如下所示：

Error during service worker registration: DOMException: Only secure origins are allowed (see: [https://goo.gl/Y0ZkNV](https://goo.gl/Y0ZkNV)).

之前一直是浏览器报出的，我用静态页面测试下，没报出这个错误，尴尬了，是react报出的。

打开https://github.com/facebook/create-react-app/blob/e898215b7ffcc436306e209227fcf393d134fe69/packages/react-scripts/template/src/index.js#L8时，如下所示：

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
import './index.css';

ReactDOM.render(<App />, document.getElementById('root'));
registerServiceWorker();

websocket的错误是由registerServiceWorker();引起，打开registerServiceWorker文件，可以看到这段代码：

function registerValidSW(swUrl) {
  navigator.serviceWorker
    .register(swUrl)
    .then(registration => {
      registration.onupdatefound = () => {
        const installingWorker = registration.installing;
        installingWorker.onstatechange = () => {
          if (installingWorker.state === 'installed') {
            if (navigator.serviceWorker.controller) {
              // At this point, the old content will have been purged and
              // the fresh content will have been added to the cache.
              // It's the perfect time to display a "New content is
              // available; please refresh." message in your web app.
              console.log('New content is available; please refresh.');
            } else {
              // At this point, everything has been precached.
              // It's the perfect time to display a
              // "Content is cached for offline use." message.
              console.log('Content is cached for offline use.');
            }
          }
        };
      };
    })
    .catch(error => {
      //here
      console.error('Error during service worker registration:', error);
    });
}

在index.js文件中，注释掉这段代码，如下所示：

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';

ReactDOM.render(<App />, document.getElementById('root'));
// registerServiceWorker();

运行项目时，将没有报错，如下所示：
