AirExpress

A web application of flight search and reservation system.

Overview

AirExpress flight search and reservation system is a RESTful web application, which serves for a demo purpose of simulating the architectures of many existing traverling agencies' website.

The system is built with several functional sections. It includes a web-server implemeted with Node, which takes responsibility for directing HTTP requirements from front-end clients. It also includes a backend Java server, which takes responsibility for the searching and reserving business logics. The system is supported by a SQL database, which stores all the flight infomation. The message flow between the web-server and backend is done throught a remote procedure call, RPC.

Prerequisites

• Linux/Ubuntu 16.04 https://nodejs.org/en/download/
• Node.js and Express.js https://www.npmjs.com/
• Java https://java.com/en/download/
• Google Map Developer Tool https://developers.google.com/maps/
• JSON-RPC 2.0 Base http://code.google.com/p/json-smart/

Installing and Test on Local Env

Download the source code on your local environment, and then navigate to the folder where the source code locates.

To start a web-server:

$ ./bin/www

The server is by default running on localhost:3000

On successful starting, the web-server will start querying airport geometry information with Google Map API. Once done it will show:

Airport loaded.

A Java PRC client instance is automatically instatiated with the web-server.

To start a backend server:

It makes easier to use an IDE to compile the source code, and then start the ExampleServer under path ./RPC/src/main/java/

The backend server is by default running on localhost:8080

On successful starting, the backend server will call an echo method to conduct a self-test. The following message will be displayed once the echo method is finished:

Request:
{"method":"echo", "id":"req-id-01","params":["Self testing query of List Param"], "jsonrpc":"2.0"}
Local Self testing query of Named Param Local Self testing query of Named Param
Test passed
{"result":"Self testing query of List Param","id":"req-id-01","jsonrpc":"2.0"}
RPC request dispatch server is running. Local port: 8080

Example HTTP Request

GET: localhost:3000/rawresult?dep_airport=BOS&ari_airport=LAX&dep_time=2017_05_12&ret_time=2017_05_14&searchButton=GO+NOW
