bundle.js:1079 Warning: React attempted to reuse markup in a container but the checksum was invalid. This generally means that you are using server rendering and the markup generated on the server was not what the client was expecting. React injected new markup to compensate which works but you have lost many of the benefits of server rendering. Instead, figure out why the markup being generated is different on the client or server:

您需要像这样将此html传递到html模板中
const App = React.createFactory(AppComponent);
const html = ReactDOMServer.renderToString(App({}));
res.status(200).send(renderFullPage(html, null));
function renderFullPage(html, initialState) {
return `
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0" />
<title>React</title>
</head>
<body>
<div id="root">${html}</div>
<script>
window.__INITIAL_STATE__ = ${JSON.stringify(initialState)}
</script>
<script src="/static/bundle.js"></script>
</body>
</html>
`
}
const-App=React.createFactory（AppComponent）；
consthtml=ReactDOMServer.renderToString（App（{}））；
res.status（200）.send（renderFullPage（html，null））；
函数renderFullPage（html，initialState）{
返回`
