javascript - app..get() 似乎在 Node.js Express 应用程序中不起作用

Question

这是 app.js 文件:

 var express = require('express'),
    routes = require('./routes'),
    api = require('./routes/api.js'),
    http = require('http'),
    path = require('path');
    var app=  module.exports = express();



/**
 * Configuration
 */

// all environments
app.set('port', process.env.PORT || 3001);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.static(path.join(__dirname, 'public')));
app.use(app.router);

// development only
if (app.get('env') === 'development') {
  app.use(express.errorHandler());
}

// production only
if (app.get('env') === 'production') {
  // TODO
};

/**
 * Routes
 */

// serve index and view partials
app.get('/', routes.index);

// redirect all others to the index (HTML5 history)
app.get('*', routes.index);


api(app);


/**
 * Start Server
 */

http.createServer(app).listen(app.get('port'), function () {
  console.log('Express server listening on port ' + app.get('port'));
});

这是routes/api.js 文件:

var queryObj = {

    retrieve:{

        api_path:'/api/test/list',
        var_name:''
    }

};

// All supporting functions used below are defined here !

module.exports = function(app) {

 _.each(queryObj, function(obj) {

        console.log("Check point 1");
        var args = [obj.api_path, function(req, res){

            var search_term = obj.var_name ? req.params[obj.var_name] : '';
            get(search_term,res);
            }];

         console.log("Check point 2");
        console.log("args:" + args);
        app.get.apply(app,args);
    });
   };

这是routes/index.js 文件:

/*
 * GET home page.
 */

exports.index = function(req, res){
 console.log("Default view");
  res.render('index');
};

因此，当我运行此应用程序并在浏览器中输入 localhost:3001/api/test/list 时，我会在控制台上得到以下输出:

检查点1
检查点2
`args: args:/api/alarms/list,函数 (req, res){

var search_term = obj.var_name ? req.params[obj.var_name] : '';
获取(搜索项，res)； }`

Express 服务器监听端口 3001 默认 View

我的问题是:为什么 app.get.apply() 不起作用？相反，app.js 中配置的默认路由被占用!

Answer 1

我认为您需要更改路由定义的顺序:从最具体(在本例中为api/test/list)到不太具体的*:

// defined api
api(app);

// serve index and view partials
app.get('/', routes.index);

// redirect all others to the index (HTML5 history)
app.get('*', routes.index);
