Question

我有这个简单的代码：

var express = require('express');
var router = express.Router();

router.get('/', function (req, res, next) {


    req.lectalApiData = {
        Model: Email,
        conditions: req.query
    };

    router.use(function(req,res,next){    //this is not executing
        console.log('do that') 
        res.json({ok:'OK'});
    });

});

我显然做错了，但根据文档，它说我可以使用这种语法： http://expressjs.com/guide/routing.html

我做错了什么？

也许是因为router.use嵌套在router.get -

中

所以我的问题就变成了 - 我如何为router.get中间件内的同一路径创建更多中间件？

Just keep adding functions to router.get('/',, they get executed in order. Don't forget to call next.

router.get('/', function (req, res, next) {
    req.lectalApiData = {
        Model: Email,
        conditions: req.query
    };
    next(); // pass off to next middleware
}, function(req,res,next){
    console.log('do that') 
    res.json({ok:'OK'});
});

or better:

function doThis(req, res, next) {
    req.lectalApiData = {
        Model: Email,
        conditions: req.query
    };
    next(); // pass off to next middleware
}

function doThat(req, res) {
    console.log('do that') 
    res.json({ok:'OK'});
}

router.get('/', doThis, doThat);

Express中间件 - router.use问题
