express 3.0如何使用app.locals.use和res.locals.use [英] express 3.0 how to use app.locals.use and res.locals.use

问题描述

我在express3.0rc2。如何使用 app.locals.use （它是否仍然存在）和 res.locals.use

我看到这个 https://github.com/visionmedia / express / issues / 1131 ，但app.locals.use引发错误。我假设一旦把函数放在app.locals.use中，我可以在路由中使用它。

我在想添加

  app.locals.use（myMiddleware（req，res，next）{res.locals.uname ='fresh'; next（）;}）
  

然后在任何路由中调用此中间件

谢谢

解决方案

我使用的是Express 3.0，这对我有用：

  app.use（function（req，res，next）{
 res.locals.myVar ='myVal'; 
 res.locals.myOtherVar =' myOtherVal'; 
 next（）; 
}）; 
  

然后我可以访问 myVal 和 myOtherVal 在我的模板中（或直接通过 res.locals ）。

I am on express3.0rc2. How to use app.locals.use(does it still exist) and res.locals.use

I saw this https://github.com/visionmedia/express/issues/1131 but app.locals.use throws an error. I am assuming that once I put the function in app.locals.use I can use it in the routes.

I was thinking of adding

app.locals.use(myMiddleware(req,res,next){res.locals.uname = 'fresh'; next();})  

and then in any route call this middleware

thanks

解决方案

I'm using Express 3.0 and this works for me:

app.use(function(req, res, next) {
  res.locals.myVar = 'myVal';
  res.locals.myOtherVar = 'myOtherVal';
  next();
});

I then have access to myVal and myOtherVal in my templates (or directly via res.locals).
