1、歷經(jīng)千辛萬(wàn)苦，UNIAPP調(diào)用評(píng)測(cè)API終于完成，在此做下總結(jié)下：首先看效果！

2、實(shí)現(xiàn)第1步，首先是鑒權(quán)，用到的CryptoJS等工具都可以從訊飛和uniapp官方獲取
import * as base64 from "base-64"
import CryptoJS from '../../static/crypto-js/crypto-js.js'
import parser from '../../static/fast-xml-parser/src/parser'
import * as utf8 from "utf8"

getWebSocketUrl() {
?? ??? ??? ??? ?return new Promise((resolve, reject) => {
?? ??? ??? ??? ??? ?// 請(qǐng)求地址根據(jù)語(yǔ)種不同變化
?? ??? ??? ??? ??? ?var url = "wss://ise-api.xfyun.cn/v2/open-ise";
?? ??? ??? ??? ??? ?var host = "ise-api.xfyun.cn";
?? ??? ??? ??? ??? ?var apiKeyName = "api_key";
?? ??? ??? ??? ??? ?var date = new Date().toGMTString();
?? ??? ??? ??? ??? ?var algorithm = "hmac-sha256";
?? ??? ??? ??? ??? ?var headers = "host date request-line";
?? ??? ??? ??? ??? ?var signatureOrigin = `host: ${host}\ndate: ${date}\nGET /v2/open-ise HTTP/1.1`;
?? ??? ??? ??? ??? ?var signatureSha = CryptoJS.HmacSHA256(signatureOrigin, this.APISecret);
?? ??? ??? ??? ??? ?var signature = CryptoJS.enc.Base64.stringify(signatureSha);
?? ??? ??? ??? ??? ?var authorizationOrigin =
?? ??? ??? ??? ??? ??? ?`${apiKeyName}="${this.APIKey}", algorithm="${algorithm}", headers="${headers}", signature="${signature}"`;
?? ??? ??? ??? ??? ?var authorization = base64.encode(authorizationOrigin);
?? ??? ??? ??? ??? ?url = `${url}?authorization=${authorization}&date=${date}&host=${host}`;

?? ??? ??? ??? ??? ?// console.log(url)
?? ??? ??? ??? ??? ?resolve(url); // 主要是返回地址
?? ??? ??? ??? ?});
?? ??? ??? ?},
3、實(shí)現(xiàn)第2不，構(gòu)建websocket連接
data() {
?? ??? ??? ?return {
?? ??? ??? ??? ?socketTask: {}, // 全局ws任務(wù)
?? ??? ??? ??? ?audioDataList: [], // 臨時(shí)錄音存儲(chǔ)集合
?? ??? ??? ??? ?APPID: '',
?? ??? ??? ??? ?APISecret: '',
?? ??? ??? ??? ?APIKey: '',
?? ??? ??? ??? ?ent: 'cn_vip',
?? ??? ??? ??? ?category: 'read_sentence',
?? ??? ??? ??? ?TEXT: '\uFEFF' + '今天天氣怎么樣',
?? ??? ??? ??? ?wsLiveFlag: false,
?? ??? ??? ??? ?iseResult: '',
?? ??? ??? ??? ?iseFinalResult: '',
?? ??? ??? ??? ?speakMark: '開始評(píng)測(cè)錄音',
?? ??? ??? ??? ?buttonGroup: [{
?? ??? ??? ??? ??? ?text: '開始評(píng)測(cè)錄音',
?? ??? ??? ??? ??? ?backgroundColor: 'green',
?? ??? ??? ??? ??? ?color: '#fff'
?? ??? ??? ??? ?}, {
?? ??? ??? ??? ??? ?text: '停止評(píng)測(cè)錄音',
?? ??? ??? ??? ??? ?backgroundColor: '#ffa200',
?? ??? ??? ??? ??? ?color: '#fff'
?? ??? ??? ??? ?}],
?? ??? ??? ?};
?? ??? ?},

?? ??? ??? ??? ??? ?realThis.iseResult = res.data;

?? ??? ??? ??? ??? ??? ?}
?? ??? ??? ??? ??? ?}
?? ??? ??? ??? ?})

?? ??? ??? ?},
4、實(shí)現(xiàn)步驟3，不斷的通過uniapp實(shí)時(shí)錄音，發(fā)送音頻給服務(wù)端API，點(diǎn)擊結(jié)束錄音發(fā)送最后一幀音頻
buttonClick(e) { // 點(diǎn)擊評(píng)測(cè)按鈕
?? ??? ??? ??? ?if (e.content.text === "開始評(píng)測(cè)錄音") {
?? ??? ??? ??? ??? ?this.speakMark = '正在評(píng)測(cè)，語(yǔ)音輸入中...'

?? ??? ??? ??? ??? ??? ?frameSize: 1, // 指定幀大小，單位 KB。傳入 frameSize 后，每錄制指定幀大小的內(nèi)容后，會(huì)回調(diào)錄制的文件內(nèi)容，不指定則不會(huì)回調(diào)。暫僅支持 mp3、pcm 格式。
?? ??? ??? ??? ??? ??? ?format: "pcm", // 音頻格式，默認(rèn)是 aac
?? ??? ??? ??? ??? ?}
