1、历经千辛万苦，UNIAPP调用评测API终于完成，在此做下总结下：首先看效果！
2、实现第1步，首先是鉴权，用到的CryptoJS等工具都可以从讯飞和uniapp官方获取
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) => {
// 请求地址根据语种不同变化
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、实现第2不，构建websocket连接
data() {
return {
socketTask: {}, // 全局ws任务
audioDataList: [], // 临时录音存储集合
APPID: '',
APISecret: '',
APIKey: '',
ent: 'cn_vip',
category: 'read_sentence',
TEXT: '\uFEFF' + '今天天气怎么样',
wsLiveFlag: false,
iseResult: '',
iseFinalResult: '',
speakMark: '开始评测录音',
buttonGroup: [{
text: '开始评测录音',
backgroundColor: 'green',
color: '#fff'
}, {
text: '停止评测录音',
backgroundColor: '#ffa200',
color: '#fff'
}],
};
},
-------------------------------------------------
async bulidSocketConnect() {
let myUrl = await this.getWebSocketUrl();
// myUrl = 'wss://wdfgdzx.top/ws_server/zs'
// console.log(encodeURI(encodeURI(myUrl).replace(/\+/g, '%2B')))
let realThis = this;
this.socketTask = uni.connectSocket({
//url: encodeURI(encodeURI(myUrl).replace(/\+/g, '%2B')),
url: myUrl,
method: 'GET',
success: res => {
console.log(res, "ws成功连接...", myUrl)
realThis.wsLiveFlag = true;
}
})
realThis.socketTask.onError((res) => {
console.log("连接发生错误", res)
})
realThis.socketTask.onOpen((res) => {
console.info("wss的onOpen成功执行...", res)
// 第一帧..........................................
console.log('open成功...')
let params = {
common: {
app_id: realThis.APPID
},
business: {
category: realThis.category,
ent: realThis.ent, // 中文
rstcd: "utf8",
sub: 'ise',
tte: 'utf-8',
cmd: "ssb",
auf: 'audio/L16;rate=16000',
aue: 'raw',
text: realThis.TEXT,
},
data: {
status: 0,
data: "",
// data: uni.arrayBufferToBase64(audioData[0]),
},
};
console.log("发送第一帧...", params)
realThis.socketTask.send({ // 发送消息，，都用uni的官方版本
data: JSON.stringify(params),
success() {
console.log('第一帧发送成功')
}
});
});
// 接受到消息时
realThis.socketTask.onMessage((res) => {
console.log('收到API返回的内容：', res.data);
realThis.iseResult = res.data;
let temp = JSON.parse(res.data)
// console.log(temp)
if (temp.code !== 0) {
console.log(`${temp.code}:${temp.message}`);
realThis.socketTask.close({
success(res) {
console.log('关闭成功', res)
realThis.wsLiveFlag = false;
},
fail(err) {
console.log('关闭失败', err)
}
})
}
if (temp.code === 0) {
if (res.data && temp.data.status === 2) {
const data = base64.decode(temp.data.data);
let decodeStr = utf8.decode(data);
console.log(temp)
console.log(decodeStr) // 打印完毕评测结果再关闭
realThis.iseFinalResult = decodeStr;
setTimeout(() => {
realThis.socketTask.close({
success(res) {
console.log('关闭成功', res)
},
fail(err) {
console.log('关闭失败', err)
}
})
}, 2000)
}
}
})
},
4、实现步骤3，不断的通过uniapp实时录音，发送音频给服务端API，点击结束录音发送最后一帧音频
buttonClick(e) { // 点击评测按钮
if (e.content.text === "开始评测录音") {
this.speakMark = '正在评测，语音输入中...'
const realThis = this;
// 开始录音，初始化一些东西
const option = {
duration: 600000, // 录音的时长，单位 ms，最大值 600000（10 分钟）
sampleRate: 16000, // 采样率（pc不支持）
numberOfChannels: 1, // 录音通道数
// encodeBitRate: 48000, // 编码码率(默认就是48000)
frameSize: 1, // 指定帧大小，单位 KB。传入 frameSize 后，每录制指定帧大小的内容后，会回调录制的文件内容，不指定则不会回调。暂仅支持 mp3、pcm 格式。
format: "pcm", // 音频格式，默认是 aac
}
recorderManager.onStart(() => {
console.log("recorder start");
});
recorderManager.onFrameRecorded((res) => {
// frameBuffer ArrayBuffer 录音分片结果数据。 isLastFrame Boolean 当前帧是否正常录音结束前的最后一帧
const {
frameBuffer
} = res;
// console.log(frameBuffer) 这里把音频放到临时的集合中，方便保存为文件
if (frameBuffer) {
realThis.audioDataList.push(frameBuffer);
// 2、判断连接了，发送中间帧..........................................
if (realThis.wsLiveFlag) {
const params = {
business: {
cmd: "auw",
aus: 2,
aue: "raw"
},
data: {
status: 1,
encoding: "raw",
data_type: 1,
data: uni.arrayBufferToBase64(frameBuffer),
},
};
console.log("发送中间帧", params, realThis.wsLiveFlag)
realThis.socketTask.send({
data: JSON.stringify(params),
success() {
console.log('中间帧发送成功')
},
fail(res) {
console.log('中间帧发送失败...', res)
}
});
}
}
});
recorderManager.start(option); // 开始录音时，建立ws连接
this.bulidSocketConnect();
//setTimeout(this.bulidSocketConnect, 2000) // main延迟2秒入口建立ws连接
}
if (e.content.text === "停止评测录音") {
this.speakMark = '开始评测录音'
// 3、发送最后一帧..........................................
const params = {
"business": {
"cmd": "auw",
"aus": 4,
"aue": "raw"
},
"data": {
"status": 2,
"encoding": "raw",
"data_type": 1,
"data": "",
}
};
this.socketTask.send({
data: JSON.stringify(params),
success(res) {
console.log('最后一帧发送成功...', res)
},
fail(res) {
console.log('最后一帧发送失败...', res)
}
});
console.log("发送最后一帧", params)
console.log('录音结束');
recorderManager.stop();
}
},
