[英]Unable to convert file to binary format for sending to wit.ai api using node.js
我在將音頻文件轉換為二進制格式時遇到問題。 我需要將其發送到Wit.AI api,該api希望使用該格式的數據。 我正在使用node.js。 在前端,我正在使用麥克風記錄器模塊記錄用戶語音。 歡迎任何建議。
我的前端代碼:
var recorder;
function startRecording() {
recorder = new MicRecorder({
bitRate: 128
});
recorder.start()
}
function stopRecording() {
recorder.stop().getMp3().then(([buffer, blob]) => {
console.log(buffer, blob);
const file = new File(buffer, 'music.mp3', {
type: blob.type,
lastModified: Date.now()
})
console.log(file)
axios({
method: 'post',
url: `${appUrl}/open_api/voice/send?data=${buffer}`
}).then(function (res) {
console.log(res)
if (res.data.success) {
console.log('done',res)
} else {
console.log(res.data)
}
})
})
};
成功錄制后,我想將文件發送到我的api以便調用wit.ai / speech api。
我的后端代碼是:
router.post('/voice/send', //chatbot response api
async (req, res, next) => {
let thread_id = '99-99-99-99'
let audioBinary = req.query.data
console.log(audioBinary)
let appId = "5d07621d6b79be66a73f4005"
let sessionId ="10-10-10-10"
let accessToken = await db.model('ChatBotApp').findOne({
_id: req.query.key
}, {
access_token: 1
}).lean()
var options = {
method: 'POST',
uri: 'https://api.wit.ai/speech?v=20190513',
body : audioBinary,
encoding: null,
headers: {
'Authorization': 'Bearer ' + "HY3ZWSUGPBPD5LWZLRSZ3QJCDC27M6EW",
'Content-Type': 'audio/mpeg',
},
// json: true // Automatically stringifies the body to JSON
};
rp(options)
.then(async function (parsedBody) {
console.log('this called',parsedBody)
return
// let response = await firstEntityValue(parsedBody, appId, message, thread_id)
// events.emit('Chats', appId, thread_id, message, sessionId, response);
return res.apiOk(response)
})
.catch(function (err) {
console.log(err)
return res.apiError('Issue while creating app!', err);
})
}
)
var recorder
function startRecording() {
recorder = new MicRecorder({
bitRate: 128
});
recorder.start()
}
function stopRecording() {
recorder.stop().getMp3().then(([buffer, blob]) => {
console.log(buffer, blob);
const file = new File(buffer, 'music.mp3', {
type: blob.type,
lastModified: Date.now()
})
var bodyFormData = new FormData();
bodyFormData.append('file', file);
console.log(file)
axios({
method: 'post',
url: `${appUrl}/open_api/voice/send`,
headers: {
'Content-Type': 'multipart/form-data'
},
data: bodyFormData
}).then(function (res) {
console.log(res)
if (res.data.success) {
console.log('done', res)
} else {
console.log(res.data)
}
})
})
};
API
router.post('/voice/send',upload.single('file'), //chatbot response api
async (req, res, next) => {
console.log(req.file)
