The user (as supplied by the verify callback), is set as a property on the request at req.user.
用户（由验证回调提供）被设置为请求的属性req.user。
Any properties of the user can be accessed through that object, in your case req.user.usernameand req.user.displayName.
用户的任何属性都可以通过该对象访问，在您的情况下req.user.username和req.user.displayName.
If you're using Express, and want to expose the username as a variable within a template, that can be done when rendering:
如果您使用 Express，并希望将用户名公开为模板中的变量，则可以在渲染时完成：
app.get('/hello', function(req, res) {
res.render('index.jade', { username: req.user.username });
});

I've created a simple view helper to have access to authentication status and user information
我创建了一个简单的视图助手来访问身份验证状态和用户信息
var helpers = {};
helpers.auth = function(req, res) {
var map = {};
map.isAuthenticated = req.isAuthenticated();
map.user = req.user;
return map;
}
app.dynamicHelpers(helpers);
After doing that you will be able to acess the object authon your views, for example auth.user.xxxx.
这样做之后，您将能够访问auth视图中的对象，例如auth.user.xxxx。

Helpers are not supported with Express v4.x
Express v4.x 不支持 Helpers
A good alternative is to create a middleware such as:
一个不错的选择是创建一个中间件，例如：
app.use((req, res, next) => {
res.locals.user = req.user;
next();
});
Then you can use the "user" variable in your views.
然后您可以在视图中使用“用户”变量。
