Question

我已经附加了客户端和服务器端代码。我正在使用套接字上载文件。它对视频文件以外的所有文件均适用。我正在分块发送数据，因此大小不会成为问题。我在做什么错了？

客户

<!DOCTYPE html>
<html>
<head>
    <meta charset=utf-8 />
    <title>Echo server</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<body>
    <h1>File Upload</h1>
    <form id="form" id="chat_form">
        <input type="file" id="file_input" />
        <input type="button" onclick="submit1()" value="submit">
    </form>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.1.1/socket.io.js"></script>
    <script type="text/javascript">
        var socket = io('http://localhost:8080');
        var fReader;
        socket.on('echo', function (data) {
            console.log(data);
        });
        socket.emit('echo', 'this is a message');
        function submit1() {
            var file = $("#file_input")[0].files[0];
            var Name = file.name;
            var reader = new FileReader();
            reader.onload = function (evnt) {
                console.log(event)
                socket.emit('join', { 'Name': Name, Data: evnt.target.result });
            }
            reader.readAsArrayBuffer(file);
        }
    </script>
</body>
</head>

服务器

var http = require('http')
var fs = require('fs');
var express = require('express')
var socketio = require('socket.io')
var app = express(server)
var server = http.Server(app)
var io = socketio(server)

app.get('/', function(req, res){
  res.sendFile(__dirname + '/client.html')
});

io.on('connection', function(socket){
  var writeStream  = fs.createWriteStream(__dirname +'/12.mkv');
  socket.on('echo', function(data){
    socket.emit('echo', data);
  });
  socket.on('join', function(chunk){
    chunk = chunk.Data;
    writeStream.write(chunk);
  })
});

server.listen(8080);
