我正在尝试从服务器向客户端发送(中继)连续的 utf-8 数据流。虽然我可以观察到达服务器的数据,但我无法将其通过管道传输到 Socket 并将其转发给客户端。
节点服务器,
var io = require('socket.io')(server);
app.io = io;
var dsteem = require('dsteem')
var es = require('event-stream')
var client = new dsteem.Client('https://api.steemit.com')
var ss = require('socket.io-stream');
var outBoundStream = ss.createStream();
var stream = client.blockchain.getBlockStream();
io.on('connection', function(socket) {
/* Eyeball the data in the nodejs console */
stream.pipe(es.map(function(block, callback) {
callback(null, util.inspect(block, {colors: true, depth: null}) + '\n')
})).pipe(process.stdout);
/* Send stream data to client */
ss(socket).on('ready', function(){
console.log('Here it comes...');
ss(socket).emit('sending', function(){
stream.pipe(es.map(function(block, callback) {
callback(null, util.inspect(block, {colors: true, depth: null}) + '\n')
}));
});
});
ss(socket).on('disconnect', function(){
console.log('Disconnected');
});
});
我可以在 nodejs 控制台中看到的数据.getBlockStream()
看起来像这个片段,
{['1b3c0394d1146cecdc0b5d38486f0b99a6d7c750',

客户,
<script src="/socket.io/socket.io.js"></script>
<script src="/javascripts/socket.io-stream.js"></script>
<script>
$(function () {
var socket = io();
ss(socket).emit('ready', 'Client ready, send me a stream...');
ss(socket).on('sending', function(stream, d){
console.log(stream);
});
});
</script>
在浏览器控制台中,我只看到此功能,
ƒ () {
var args = slice.call(arguments);
args = self.encoder.encode(args);
ack.apply(this, args);
}
谁能帮我理解我做错了什么?
