微信小程序智能生活小秘书开发详解
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。

源码分析
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.js const corpusList = require('./config').corpus var 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
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', ] };
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。

index.json
首页延用app.json中的配置,不需要单独的配置,这里主要配置一个允许下拉。
{ "window": { "enablePullDownRefresh": true } }
index.wxml
这个是首页的h5布局。

首页用到的一些样式,以及配置首页背景图片。
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)。

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:
