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。

开发资源
- 免费开放语义接口平台 olami.ai
- 微信小程序平台
- 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.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
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',

]
};

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。
{{outputTxt}}
语义理解基于“欧拉密”：cn.olami.ai
支持“摇一摇”、点按钮、手动输入、向下拉
index.wxss
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）。

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：
