实现功能

实现一个智能生活信息查询的小秘书功能，支持查天气、新闻、日历、汇率、笑话、故事、百科、诗词、邮编、区号、菜谱、股票、节目预告，还支持闲聊、算24点、数学计算、单位换算、购物、搜索等功能。
使用方式上支持摇一摇、点界面按钮、手动输入、下拉刷新这四种方式。

免费开放语义接口平台 olami.ai

js, css

源码分析

源码各文件说明

基本延用官方案例的目录结构和命名，index.xx是首页面相关代码，logs.xx是日志页相关代码。

比官方目录结构多了两个文件：

config.js
因为用到一些配置，放在.js里封装起来比较好。
pics/bg.jpg
小程序背景图片，开发环境上加载本地文件作为背景图片是生效的，预览体验时不生效，网上有人说不支持本地文件，因此这里这个图片其实没有用到，只是暂时留着。

####小程序根目录文件：app.js, app.json, app.wxss, config.js

app.js

提供获取用户微信账号昵称和所在地，获取当前地理位置这两个公共接口。

//app.jsconst corpusList = require('./config').corpusvar UTIL = require('./utils/util.js');App({  onShow: function () {    UTIL.log('App Show')  },  onHide: function () {    UTIL.log('App Hide')  },  onLaunch: function () {    UTIL.log('App Launch')    this.updateUserLocation()  },  updateUserLocation: function() {    var that = this    wx.getLocation({      //type: 'wgs84',  // gps原始坐标      type: 'gcj02', //国家标准加密坐标      success: function (res) {        that.globalData.latitude = res.latitude        that.globalData.longitude = res.longitude        that.globalData.speed = res.speed        //var accuracy = res.accuracy        UTIL.log('REFRESH LOCATION: ' + that.globalData.latitude + ' | ' + that.globalData.longitude + ' , speed: ' + that.globalData.speed)      },      fail: function(res) {        UTIL.log('REFRESH LOCATION FAILED...')      }    })  },  getUserInfo:function(cb){    var that = this    if(this.globalData.userInfo){      typeof cb == "function" && cb(this.globalData.userInfo)    }else{      //调用登录接口      wx.login({        success: function () {          wx.getUserInfo({            success: function (res) {              that.globalData.userInfo = res.userInfo              that.globalData.custId = UTIL.getUserUnique(that.globalData.userInfo);              typeof cb == "function" && cb(that.globalData.userInfo)            }          })        },        fail: function () {          UTIL.log('登录WX失败了！')        }      })    }  },  clearUserInfo: function() {    var that = this    that.globalData.userInfo = null;    that.globalData.hasLogin = false;  },  globalData:{    userInfo:null,    corpus: corpusList,    custId: '',    latitude: 0.0,    longitude: 0.0,    speed: 0,  }})

app.json

配置小程序窗体相关属性：标题名称，背景色，网络超时等。
配置首页面为pages/index/index。

{  "pages": [    "pages/index/index",    "pages/logs/logs"  ],  "window": {    "backgroundTextStyle": "black",    "navigationBarBackgroundColor": "#F8F8F8",    "navigationBarTitleText": "遥知之 -- olami语义支持",    "navigationBarTextStyle": "black",    "backgroundColor": "#F8F8F8"  },  "networkTimeout": {    "request": 10000,    "connectSocket": 10000,    "uploadFile": 10000,    "downloadFile": 10000  }}

app.wxss

配置了“遥知之”小程序container全局样式

/**app.wxss**/.container {  height: 100%;  display: flex;  flex-direction: column;  align-items: center;  justify-content: center;  box-sizing: border-box;}

配置文件：config.js

保存一些配置信息，包括NLI的key和secret，还有小程序中预置的语料集合。

module.exports = {  //NLI appkey  appkey: `b4118cd178064b45b7c8f1242bcde31f`,  //NLI appsecret  appsecret: `7908028332a64e47b8336d71ad3ce9ab`,    corpus: [    // '闲聊',    // '天气',    // '诗词',    // '单位换算',    // '新闻',    // '算24点',    // '菜谱',    // '汇率',    // '邮编',    // '区号',    // '股票',    // '日历',    // '节目预告',    // '笑话',    // '故事',    // '购物',    // '数学运算',    // '百科',    // '搜索',    '你今年多大啦',    '上海今天天气如何',    '北京的呢',    '李白写过什么诗',    '我要听李白的静夜思',    '背一首将进酒',    '一公里等于多少英尺',    '我要看体育新闻',    '4567算24点',    '红烧肉的做法',    '1美元能换算多少人民币',    '查一下南昌的邮编',    '郑州的区号是多少',    '中国石油的股价',    '今年中秋节是哪一天',    '明晚湖南卫视放什么节目',    '来个笑话',    '讲个故事听听',    '我要买电脑',    '1加到100等于多少',    '黄山有多高',    '百度搜一下薛之谦的照片',  ]};

####utils目录文件：GUID.js, MD5.js, NLI.js, util.js

获取随机GUID：GUID.js

olami平台资源配置

，在配置上稍微有些不同，下面我会重点说明一下。

用上次注册的账号，在olami.ai上登录。
选择“API&解决方案”中的“NLI 自然语言语义互动管理系统”，然后点“开始免费试用”进入应用配置界面。
生成一个新的应用，比如取名“遥知之NLI能力”
点“配置模块”进去，会有两个标签页：
a. “NLI模块”：我之前做过一个汇率换算的小DEMO 用olami开放语义平台做汇率换算应用用的是使用“NLI模块”的功能，其实就是语义接口。
b. “对话系统模块”：这次做“遥知之”微信小程序，用的是他们平台的“处理结果”的能力，就是对应“对话系统模块”这里。
注：有些朋友估计会有点弄不清楚，这里我举个例子，比如“今天上海的天气如何”这一句话：应用配置在“NLI模块”里勾天气相对应的模块，接口会返回这一句话的意思“今天，上海，查天气”；应用配置在“对话系统模块”里勾“weather”，接口返回的就是今天上海天气的查询结果。
好了，弄明白上述两块，接下来就知道，这次我做的“遥知之”全是要结果输出的，所以把“对话系统模块”中所有的功能模块全勾选上了，后面有配置优先级的，优先级是用来处理语义冲突时仲裁哪个模块优先的，我都没有动，直接用默认值，根据提示：数值越小优先级越高，1000是优先级最高。
“遥知之NLI能力”应用中，点击“查看Key”可以获取调用OLAMI开放语义平台的授权密钥，包括“App Key”和“App Secret”。这两个码，对应小程序源码中的“config.js”中的“appkey”和“appsecret”。
“遥知之NLI能力”应用中有个“测试”，需要的话，可点进去输入一些句子测输出结果（注：这里是NLI接口输出的一部分）。

写在最后

这次做微信小程序，是边摸索边做，JS和CSS基本是边改边学，好在微信小程序框架清晰，接口文档全，另外olami平台之前做用olami开放语义平台做汇率换算应用时接触过，所以总体来讲还算顺利。

另外这里特意推荐一下跟自然语言理解相关的比较不错的文章：
