I'm trying to send a file (.obj file) via formdata to my node server, it appears that everything is fine until the controller of the endpoint on the server throws an error that seems to be like the formdata parser is receiving an empty formdata object, here is the error in question. Now, here's my code:
Fron-end (where the request is being executed):
const data = new FormData();
data.append('file', this.props.filesSubmit, this.props.filesSubmit.name);
for (var pair of data.entries()) {
console.log(pair[0] + ', ' + pair[1]);
}
await axios
.post(
'https://hushpuppys-3d-hub-api.herokuapp.com/api/v1/modelfiles/',
data,
{
headers: {
'Content-Type': undefined,
},
}
)
.then((res) => {
console.log('File Upload Successful! Res: ', res);
})
.catch((err) => {
console.log(err);
});
Back-end endpoint Controller (Where request is received):
const AWS = require('aws-sdk');
const fs = require('fs');
const fileType = require('file-type');
const bluebird = require('bluebird');
const multiparty = require('multiparty');
// Keys Configuration to Access AWS
AWS.config.update({
accessKeyId: '[I erased this]',
secretAccessKey: '[I erased this]',
});
// Configuring AWS to work with promises
AWS.config.setPromisesDependency(bluebird);
// Creating S3 instance
const s3 = new AWS.S3();
// abstracts function to upload a file returning a promise
const uploadFile = (buffer, name, type) => {
const params = {
ACL: 'public-read',
Body: buffer,
Bucket: '[I erased this]',
ContentType: type.mime,
Key: `${name}.${type.ext}`,
};
return s3.upload(params).promise();
};
exports.fileUploaderController = (req, res) => {
const form = new multiparty.Form();
form.parse(req.body, async (error, fields, files) => {
if (error) throw new Error(error);
try {
const path = files.file[0].path;
const buffer = fs.readFileSync(path);
const type = fileType(buffer);
const timestamp = Date.now().toString();
const fileName = `bucketFolder/${timestamp}-lg`;
const data = await uploadFile(buffer, fileName, type);
return res.status(200).send(data);
} catch (error) {
return res.status(400).send(error);
}
});
};
I want to also add the code of my app.js where other middlewares manipulate the body, maybe that's also relevant to solve the problem:
const express = require('express');
const modelRouter = require('./routes/modelRoutes');
const modelFilesRouter = require('./routes/modelFilesRoutes');
const cors = require('cors');
const app = express();
// MIDDLEWARES
app.use(cors());
app.use(express.json({ limit: '50mb' }));
app.use(express.urlencoded({ limit: '50mb' }));
// ROUTES
app.use('/api/v1/models', modelRouter);
app.use('/api/v1/modelfiles', modelFilesRouter);
module.exports = app;
