I have a C# code snippet that is successfully working with another NodeJS Express application, the source code of which I do not have access to. However, I want to keep this code unchanged.
string filetoupload = @"D:\testvideo.mp4";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://127.0.0.1:10090" + "/upload?name=" + WebUtility.UrlEncode(Path.GetFileName(filetoupload)));
request.Method = "PUT";
request.ContentType = MimeTypesMap.GetMimeType(Path.GetExtension(filetoupload));
using (FileStream fs = File.OpenRead(filetoupload))
{
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
request.ContentLength = buffer.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(buffer, 0, buffer.Length);
requestStream.Flush();
requestStream.Close();
WebResponse upresponse = request.GetResponse();
Stream updataStream = upresponse.GetResponseStream();
StreamReader upreader = new StreamReader(updataStream);
string upres = upreader.ReadToEnd();
Console.WriteLine("RES: " + upres);
}
The issue arises when trying to properly read stream data on the NodeJS Express server side. I have managed to store the file on disk using the following code:
const express = require('express');
const fs = require('fs');
const app = express();
const port = process.env.PORT || 10090;
app.listen(port, () =>
console.log(`App is listening on port ${port}.`)
);
app.put('/upload', async (req, res) => {
try {
var socket = req.socket;
socket.on('data', function(data) {
fs.appendFile("somevideo.mp4", new Buffer(data), function (err,data) {
if (err) {
res.status(500).send(err);
}
});
});
res.send({
status: true,
message: 'File uploaded'
});
} catch (err) {
res.status(500).send(err);
}
});
However, I need to perform additional tasks after the file is stored on disk (such as creating a hash code, MySQL operations, etc.) and then return text data as a response message. The challenge for me is determining when these tasks are completed.
Is there a better approach to handle file uploads like this?
