Location Server/Client Demo 3.0.2

by vampirefan

NOTE: Using mongodb to store and frame fingers.

The Server:

1. install nodejs.
2. install and setup mongodb.
3. into the dictory: cd $(locationServerDemo)
4. start the server: node app.js

The finger DataBase (JSON)

    fingerPrints:
    # locationId: 

    # bearing:
    (罗盘显示的)方位

    # wapInfo
    各个wap的信号强度值
    ## bssid
    wap的bssid值
    ## rssid
    wap的信号强度值

    # options:可选数据
    ## wapNumScan:
    扫描到wap的个数

    example:
        [{
            "locationId": "X62 1 1 1 1",
            "bearing": 0,
            "wapInfo": [{
                "bssid": "00:60:2f:3a:07:35",
                "rssid": -58
            }, {
                "bssid": "00:60:2f:3a:07:65",
                "rssid": -69
            }, {
                "bssid": "00:60:2f:3a:07:15",
                "rssid": -64
            }, {
                "bssid": "00:60:2f:3a:07:f5",
                "rssid": -25
            }, {
                "bssid": "00:60:2f:3a:07:b5",
                "rssid": -67
            }]
        }, {
            "locationId": "X62 1 1 1 2",
            "bearing": 0,
            "wapInfo": [{
                "bssid": "00:60:2f:3a:07:35",
                "rssid": -45
            }, {
                "bssid": "00:60:2f:3a:07:65",
                "rssid": -56
            }, {
                "bssid": "00:60:2f:3a:07:15",
                "rssid": -67
            }, {
                "bssid": "00:60:2f:3a:07:f5",
                "rssid": -78
            }, {
                "bssid": "00:60:2f:3a:07:b5",
                "rssid": -89
            }]
        }]

The Client:

1. start the Client.
2. Set the Server's host IP Address and port.

NOTE: check the example fingerFrame and locateFrame in ./db/

the postData fingerfraem (JSON)

    {
        "locationId": "X62 1 1 1 3",

    }

the postData locateframe (JSON)

    # bearing:
    (罗盘显示的)方位

    # wapInfo
    各个wap的信号强度值
    ## bssid
    wap的bssid值
    ## rssid
    wap的信号强度值
    example: 
        {

                "rssid": 89
            }]
        }

Function:

use url parse and http post to get the system work

example:

+ `/start`, `/`: test connection;
+ `/login`: get the instruction;
+ `/finger`: post current locationId and wap_rssids;
+ `/locate`: post current wap_rssids and get current locationId;
+ `/dbshow`: get a instance glance of the fingerprints database;
+ `/LocationServerTest.fingerprints.remove()`: remove all fingerprints data;
