Minimal backend proxy for synchronous transcription.
|
|
|
|
```js
|
|
import express from 'express';
|
|
import multer from 'multer';
|
|
import { KJUR } from 'jsrsasign';
|
|
|
|
const app = express();
|
|
const upload = multer({ storage: multer.memoryStorage() });
|
|
app.use(express.json());
|
|
|
|
function generateJWT() {
|
|
const iat = Math.round(Date.now() / 1000) - 30;
|
|
const exp = iat + 60 * 60;
|
|
return KJUR.jws.JWS.sign(
|
|
'HS256',
|
|
JSON.stringify({ alg: 'HS256', typ: 'JWT' }),
|
|
JSON.stringify({ iss: process.env.ZOOM_API_KEY, iat, exp }),
|
|
process.env.ZOOM_API_SECRET,
|
|
);
|
|
}
|
|
|
|
app.post('/transcribe', upload.single('file'), async (req, res) => {
|
|
const token = generateJWT();
|
|
const config = {
|
|
language: req.body.language || 'en-US',
|
|
word_time_offsets: true,
|
|
channel_separation: false,
|
|
};
|
|
|
|
let response;
|
|
if (req.file) {
|
|
const form = new FormData();
|
|
form.append('file', new Blob([new Uint8Array(req.file.buffer)]), req.file.originalname);
|
|
form.append('config', JSON.stringify(config));
|
|
response = await fetch('https://api.zoom.us/v2/aiservices/scribe/transcribe', {
|
|
method: 'POST',
|
|
headers: { Authorization: `Bearer ${token}` },
|
|
body: form,
|
|
});
|
|
} else {
|
|
response = await fetch('https://api.zoom.us/v2/aiservices/scribe/transcribe', {
|
|
method: 'POST',
|
|
headers: {
|
|
Authorization: `Bearer ${token}`,
|
|
'Content-Type': 'application/json',
|
|
},
|
|
body: JSON.stringify({
|
|
file: req.body.file,
|
|
config,
|
|
}),
|
|
});
|
|
}
|
|
|
|
const text = await response.text();
|
|
res.status(response.status).type('application/json').send(text);
|
|
});
|
|
```

Use this pattern when:
|
|
- the caller uploads a file to your backend and you forward it as multipart
|
|
- or the caller already has a URL-accessible media file and you submit the JSON URL form
