When i am uploading file from frontend with formdata as body of post request, Backend is returning 400 bad request.
const formData = new FormData();
formData.append("file", this.fileSelected);
formData.append("type", "ALLOC");
when i check the backend logs, then its saying file is undefined, It means proxy drops the multipart formdata
client --> proxy server --> backend
global middlewares
app.use(morgan("dev"));
app.use(cors(corsOptions));
app.use(bodyParser.json());
app.use(express.urlencoded({ extended: false }));
// restream parsed body before proxying
let restream = function(proxyReq, req, res, options) {
console.log("################");
console.log(req.body);
console.log(req.file);
console.log(req.type);
console.log(req.filename);
if (req.body) {
let bodyData = JSON.stringify(req.body);
proxyReq.setHeader('Content-Type','application/json');
proxyReq.setHeader('Content-Length', Buffer.byteLength(bodyData));
proxyReq.write(bodyData);
}
}
router.use('',checkAuthentication,createProxyMiddleware({
target: config.MAIN_SERVER_BASE_URL,
changeOrigin: true,
on: {
proxyReq: restream
}
}));
I need to handle both json request and formdata.
