我正在开发一个小型 PeerJS 项目，我有点困惑。我能够打开连接并确认客户端已连接，但我无法找出接收任何内容的正确方法或语法。或者也许我只是错过了一些简单的事情。我尝试了很多变体试图让它发挥作用。下面是 JS 和 HTML。
JS:
var peer = new Peer({
key: 'lwjd5qra8257b9'
// I use my own API key for testing, this is the public PeerJS key
//you'll have to generate your own if this doesn't work.
});
peer.on('open', function(id) {
$('body').append('<br/>Your personal peer ID is: ' + id + '<br/>Be careful who you share it with.');
});
peer.on('connection', connect);
function connect(succ) {
conn = succ;
//input changes on successful connect
$('#peerKeyEnter').val(conn.peer);
$('#peerKeyEnter').prop('disabled',true);
}
$(document).ready(function() {
$('#peerKeySubmit').on('click', function() {
var buddy = document.getElementById('peerKeyEnter').value;
var buddyConn = peer.connect(buddy); //send connection request
connect(buddyConn); //connect to peer
//sending data
buddyConn.on('open', function() {
buddyConn.send('this is supposed to work')
});
//receiving data
buddyConn.on('connection', function(conn) {
buddyConn.on('data', function(data) {
console.log(data);
});
});
}); //end peerKeySubmit.click
}); //end doc.ready()
HTML:
<html>
<head>
<script
src="https://code.jquery.com/jquery-3.2.1.js"
integrity="sha256-DZAnKJ/6XZ9si04Hgrsxu/8s717jcIzLy3oi35EouyE="
crossorigin="anonymous"></script>
<!--script src='peer.js'></script-->
<script src="http://cdn.peerjs.com/0.3/peer.js"></script>
<script src='app.js'></script>
</head>
<body>
<input type='text' id='peerKeyEnter' placeholder="Enter peer's ID"></input>
<button id='peerKeySubmit' value='Send'>Select Peer</button>
</body>
</html>
最佳答案
事实上，你就快到了。您的 buddyConn.on('data'... 应该位于 connect 函数中，使用该函数的参数名称进行连接。此外，对 connect 的第二次调用 不应出现在 #peerKeySubmit.on 回调函数中。以下是修改后的(工作)代码:
var peer = new Peer({
key: 'lwjd5qra8257b9'
// I use my own API key for testing, this is the public PeerJS key
//you'll have to generate your own if this doesn't work.
});
peer.on('open', function(id) {
$('body').append('<br/>Your personal peer ID is: ' + id + '<br/>Be careful who you share it with.');
});
peer.on('connection', connect);
function connect(succ) {
conn = succ;
conn.on('data', function (data) {
console.log('Received from ' + conn.peer + ': ' + data);
});
//input changes on successful connect
$('#peerKeyEnter').val(conn.peer);
$('#peerKeyEnter').prop('disabled',true);
}
$(document).ready(function() {
$('#peerKeySubmit').on('click', function() {
var buddy = document.getElementById('peerKeyEnter').value;
var buddyConn = peer.connect(buddy); //send connection request
//sending data
buddyConn.on('open', function() {
buddyConn.send('this is supposed to work')
});
}); //end peerKeySubmit.click
}); //end doc.ready()
