Express服务器接收POST请求

以下是Express程序

问题：：我在CLIENT中没有得到正确的JSON响应

我想知道的是：

• 当我从客户端发出发布请求时，是否在server（Express）中编写了正确的代码
• 客户端以(Key,Value)成对的形式发送请求
• 我敢肯定我遇到问题的请求结构

我该如何解决？

var express = require('express')
  , async = require('async')
  , http = require('http')
  , mysql = require('mysql');

var app = express();

var connection = mysql.createConnection({
    host: 'localhost',
    user: '*************',
    password: "**************",
    database: 'restaurants'
});

connection.connect();

// all environments
app.set('port', process.env.PORT || 1828);


app.get('/RestaurantDesc/:Key',function(request,response,next){

    var keyName=request.params.Key;
    var name_of_restaurants, RestaurantTimings;
    async.series( [
        // Get the first table contents
        function ( callback ) {
            connection.query('SELECT * FROM ',keyName, function(err, rows, fields)
                {
                        console.log('Connection result error '+err);
                        name_of_restaurants = rows;
                        callback();
                });
        },
        // Get the second table contents
        function ( callback ) {
        connection.query('SELECT * FROM RestaurantTimings', function(err, rows, fields)

            {
                    console.log('Connection result error '+err);
                    RestaurantTimings = rows;
                    callback();
            });
        }

   // Send the response
], function ( error, results ) {
    response.json({
        'restaurants' : name_of_restaurants,
        'RestaurantTimings' : RestaurantTimings
    });
} );
} );




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

有任何想法吗？
