使用IoT-CoAP构建物联网

(注意：windows系统npm install失败时，需要自己建立一个C:\Documents and Settings[USERNAME]\Application Data\npm 文件)

  1. npm install iot-coap

1.新建index.js

注意: 如果已经存在一个index.js文件，请将下面内容添加到文件末尾(create index.js, and add)

  1. var iotcoap         = require('iot-coap');
  3. iotcoap.run();
  4. iotcoap.rest.run();

注意:在db配置可以选择mongodb和sqlite3，替换所需要的数据库即可。(you can choice db on iot.js with ‘sqlite’ or ‘mongodb’)

2.创建iot.js

  1. exports.config  = {
  2.     "db_name": "iot.db",
  3.     "mongodb_name": "iot",
  4.     "mongodb_documents": "iot",
  5.     "db": "mongodb",
  6.     "table_name": "basic",
  7.     "keys":[
  8.         "id",
  9.         "value",
  10.         "sensors1",
  11.         "sensors2"
  12.     ],
  13.     "db_table": "id integer primary key, value text, sensors1 float, sensors2 float",
  14.     "mongodb_init":[
  15.         {
  16.             id: 1,
  17.             value: "is id 1",
  18.             sensors1: 19,
  19.             sensors2: 20
  20.         },
  21.         {
  22.             id: 2,
  23.             value: "is id 2",
  24.             sensors1: 20,
  25.             sensors2: 21
  26.         }
  27.     ],
  28.     "init_table":[
  29.         "insert or replace into basic (id,value,sensors1,sensors2) VALUES (1, 'is id 1', 19, 20);",
  30.         "insert or replace into basic (id,value,sensors1,sensors2) VALUES (2, 'is id 2', 20, 21);"
  31.     ],
  32.     "query_table":"select * from basic;",
  33.     "rest_url": "/id/:id",
  34.     "rest_post_url": "/",
  35.     "rest_port": 8848
  36. };

3.运行(run)

  1. node index.js

show:

  1. coap listening at coap://0.0.0.0:5683
  2. restify listening at http://0.0.0.0:8848
