使用 Node Js 将录制的 wav 音频上传到 API

如何解决使用 Node Js 将录制的 wav 音频上传到 API

我尝试录制我的声音以发送到 API 然后转换为文本，我使用 NodeJs 将我的声音发送到 API，如何检索我录制的语音而不将其保存到文件或文件夹中而是直接将其发送到音频形式的 API？这是我上传录音的代码

// routes.js
import voiceBotController from "../controllers/voiceBotController";


// upload config
const upload = mutler({
    limits: {
        fileSize: 2 * 1024 * 1024,files: 1 // 1 file
    }
})

let router = express.Router();

let initWebroutes = (app) => {
    router.get("/",indexController.getIndex); 
    router.get("/webhook",chatbotController.getWebhook);
    router.post("/webhook",chatbotController.postWebhook);

    // voice handing
    router.post("/upload",voiceBotController.postVoice,upload.single("myfile"));
    

    return app.use('/',router);
};

和我的控制器

// dotenv
require("dotenv").config()

// environtment
const WIT_TOKEN = process.env.WIT_SERVER_ACCESS_TOKEN;

// handling POST voice to wit.ai
let postVoice = (req,res,next) => {
    let upFile =  req.files.myfile;
    console.log("File Uploaded: ");
    console.log(upFile);
    var buffer = upFile.data;

    // define url and Make Post to wit.ai API
    const url = "https://api.wit.ai/speech";

    // post Data using axios To Wit.ai API speech
    axios.post(url,buffer,{
        headers: {
            "Authorization": "Bearer " + WIT_TOKEN,"Content-Type": "audio/wav"
        }
    
    }).then(witResponse => {
        console.log("Wit.ai Response: "  + JSON.stringify(witResponse.data));
        res.json(witResponse.data)
    
    }).catch(err => {
        console.log("Error sending to wit: " + err);
        res.json({error: err.message});
    });

}

// export module
module.exports = {
    postVoice: postVoice,}

在这里，我对如何录制我的录音然后将其发布到 API 感到困惑
