最近开发记录
程序要求：工厂内通讯使用，及时联络处理问题，收到消息及时提醒用户处理。目前已测试android4以上
1.保持程序后台运行
2.维持长连接，接收即时消息，后台播放无声音乐，每十秒执行一次，无声音乐长度为1秒
3.接收到信息，显示通知，提醒，语音播报
4.消息存储，根据不同的消息跳转不同的页面
需要用到插件
1.cordova-plugin-background-mode 后台运行
2.cordova-plugin-appminimize 程序最小化
3. 即时消息采用第三方融云
4. cordova-plugin-nativeaudio 播放本地音频
5.cordova-plugin-local-notification 本地消息通知
6.语音播报采用百度语音合成
7.cordova-sqlite-storage 存储消息
1.后台运行插件（ionic3版本，如果是ionic4，按照4的文档添加）
1.1 添加插件
$ ionic cordova plugin add cordova-sqlite-storage
$ npm install --save @ionic-native/sqlite@4
$ ionic cordova plugin add cordova-plugin-appminimize
$ npm install --save @ionic-native/app-minimize@4
1.2 插件添加到应用程序的模块中（此处不讲）

2 集成融云
由于测试期间使用融云web SDK在android6以下出现连接融云服务器受限，出现403状态码，最后为了解决该问题，暂时在android6以下版本采用融云cordova插件代替
2.1 添加融云cordova插件
$ ionic cordova plugin add cordova-plugin-rongcloud-im
2.2 添加web版融云

image.png
2.3 在app.component中
/// <reference path="../assets/js/RongIMLib-2.3.2.d.ts" />
如图：

3 添加播放音频与本地通知
3.1 添加插件
$ ionic cordova plugin add cordova-plugin-nativeaudio
$ npm install --save @ionic-native/native-audio@4
$ ionic cordova plugin add cordova-plugin-local-notification
$ npm install --save @ionic-native/local-notifications@4
3.2 插件添加到应用程序的模块中、
3.3 创建AudioServiceProvider
$ ionic g provider AudioService
3.4 修改AudioServiceProvider
import { StorageServiceProvider } from './../storage-service/storage-service';
import { HelperProvider } from './../helper/helper';
import { Injectable } from '@angular/core';
import { NativeAudio } from '@ionic-native/native-audio';
/*

and Angular DI.
*/
@Injectable()
export class AudioServiceProvider {

audio: HTMLAudioElement;
constructor(private nativeAudio: NativeAudio,
private helper: HelperProvider,
private storageService: StorageServiceProvider) {
// this.nativeAudio.preloadComplex('bell', 'assets/bell.mp3', 1, 1, 0).catch(e => console.log(e));
//缓存无声音频
this.nativeAudio.preloadComplex('no', 'assets/no.mp3', 1, 1, 0).catch(e => console.log(e));
// this.nativeAudio.preloadComplex('prompt', 'assets/prompt.mp3', 1, 1, 0).catch(e => console.log(e));
//添加收到消息提示声音，为了兼容低版本vivo和web端
this.audio = document.createElement('audio');
this.audio.src = 'http://xxx/assets/file/prompt.mp3';
this.audio.autoplay = false;
}
/**

*/

clearInterval(this.time);
}

}
}, 9000);
},10000)
}
/**

*/
stopBackground(){

this.nativeAudio.stop('no');
}
/**
* 播放消息提示声音
*/
playMsg(){
// this.nativeAudio.play('prompt');
this.audio.play();
}
}
3.5 修改app.component，追加代码
import { AudioServiceProvider } from '../providers/audio-service/audio-service';
import { LocalNotifications } from '@ionic-native/local-notifications';
constructor(private audioService: AudioServiceProvider,
private localNotifications: LocalNotifications) {}
/**
* 设置后台运行
*/
setBackground() {
this.audioService.backgroundPlay();
}
/**
* 连接融云
*/
connectRongCloud() {
this.events.subscribe('message:new', message => {
// 播放消息声音
this.audioService.playMsg();
if (this.helper.isMobile()) {
//显示通知
this.localNotifications.schedule({
id: message.id,
icon: 'res://ic_chat',
smallIcon: 'res://ic_chat',
sound: null,
silent: true,
title:message.title,
text: message.content,
data: message
});
//监听点击事件
this.localNotifications.on('click').subscribe(res => {
//清除所有消息
this.localNotifications.clearAll();
});
}
});
}
4 集成百度语音合成
一开始采用cordova-plugin-tts进行播报，设置语言为中文，但在vivo手机出现只读英文，中文被过滤无法播报，好像是编码问题，后来选用百度语音合成，因为免费
4.1 创建应用
image.png
成功后会得到AppID，API Key，Secret Key
4.2 Java后台设置
后台写一个接口代码，播放参数前端传给后台

@RequestParam("vol") String vol,
@RequestParam("per") String per,
HttpServletResponse response
) throws Exception {
HashMap<String, Object> option = new HashMap<>();
option.put("cuid", cuid);
option.put("spd", spd);
option.put("pit", pit);
option.put("vol", vol);
option.put("per", per);
byte[] buff = ttsUtils.textToSpeech(tex, lan, ctp, option);
if (buff != null) {
response.setContentType("audio/mp3");
OutputStream outputStream = response.getOutputStream();
outputStream.write(buff);
outputStream.close();
}
}
4.3 创建TtsServiceProvider
$ ionic g provider TtsService
填写代码
import { StorageServiceProvider } from './../storage-service/storage-service';
import { Injectable } from '@angular/core';
import { ConfigProvider } from '../config/config';
/*
Generated class for the TtsServiceProvider provider.
See https://angular.io/guide/dependency-injection for more info on providers
and Angular DI.
*/
@Injectable()
export class TtsServiceProvider {
audio: any;
options = {
lan: "zh",//语言
ctp: '1',
cuid: '',//唯一标识
tex: '',//播放内容
spd: 5,//语速，取值0-15，默认为5中语速
pit: 5,//音调，取值0-15，默认为5中语调
vol: 15,//音量，取值0-15，默认为5中音量
per: 0//发音人选择, 0为普通女声，1为普通男生，3为情感合成-度逍遥，4为情感合成-度丫丫，默认为普通女声
}
constructor( private storageService: StorageServiceProvider) {
}
/**
* 初始化百度tts
*/
init() {
this.audio = document.createElement('audio');
this.audio.autoplay = false;
//如果第一次启动，参数不存在，则存储默认参数
if (!this.storageService.read("baiduTTS")) {
this.storageService.write("baiduTTS", this.options);
}
}
/**
* 播放内容
* @param text
*/
speak(text: string) {
//读取最新存储语音设置
this.options = this.storageService.read("baiduTTS");
this.options.cuid = 'xxx';//此处应为用户唯一标识
//url编码
this.options.tex = encodeURIComponent(text);
//设置地址为后台播放地址
this.audio.src = 'http://xxx/message/getAudio' + '?' + this.toBodyString(this.options);
this.audio.play();
}
}
/**
* 停止播放
*/
stop() {
this.audio.pause();
}
/**
*
* @param obj
* @return {string}
* 声明: var obj= {};
* 调用: toQueryString(obj);
* 返回: "name=%E5%B0%8F%E5%86%9B&age=23"
*/
toBodyString(obj) {
let ret = [];
for (let key in obj) {
if (key != 'constructor') {
key = encodeURIComponent(key);
let values = obj[key];
if (values && values.constructor == Array) {//数组
let queryValues = [];
for (let i = 0, len = values.length, value; i < len; i++) {
value = values[i];
queryValues.push(this.toQueryPair(key, value));
}
ret = ret.concat(queryValues);
} else { //字符串
ret.push(this.toQueryPair(key, values));
}
}
}
return ret.join('&');
}
private toQueryPair(key, value) {
if (typeof value == 'undefined') {
return key;
}
return key + '=' + encodeURIComponent(value === null ? '' : String(value));
}
}
4.4 修改app.component，追加代码
import { TtsServiceProvider } from '../providers/tts-service/tts-service';
constructor(private ttsService: TtsServiceProvider) {}
initializeApp() {
this.platform.ready().then(() => {
// Okay, so the platform is ready and our plugins are available.
// Here you can do any higher level native things you might need.
// 初始化百度tts
this.ttsService.init();
});
}
/**
* 连接融云
*/
connectRongCloud() {
this.events.subscribe('message:new', message => {
// 播放文本
this.ttsService.speak( message.content);
if (this.helper.isMobile()) {
this.localNotifications.on('click').subscribe(res => {
//清除该条
this.audioService.stopPlay();
//停止播放
this.ttsService.stop();
this.localNotifications.clearAll();
});
}
});
}
代码有删减，可能存在缺失代码问题，可惜的是本地通知在待机状态下并不能出现
