效果:
这边对微信说话, 浏览器端及时显示语音识别的文字
注意:
在连接socket.io时, 按下浏览器f12, 如果一直有请求不断的刷, 说明socket.io没有连接成功
代码:
node.js server端
1 var module_path = ‘/usr/local/web/node/bin/node_modules/‘;
2 var html = ‘<html> <head> <meta charset="utf-8"> <title>微信接口</title> <script src="http://cdn.bootcss.com/jquery/2.1.4/jquery.js"></script> <script src="http://cdn.bootcss.com/socket.io/1.3.5/socket.io.js"></script> </head> <body> <div id="voice"> 两秒钟同步一次:<br><br> </div> <script type="text/javascript"> var voice = document.getElementById("voice"); var socket = io.connect("http://www.zhangzhibin.com:1337"); socket.on("hello", function(data){console.log(data); socket.emit("hello", {"status":"ok"}); }); socket.on("emit", function(data){var t = data+"<br>"; voice.innerHTML += t; socket.emit("emit", {"get":"data"}); }); </script> </body> </html>‘;
3 //链接redis
4 var redis = require(module_path+‘redis‘);
5 var redis_client = redis.createClient(6379, ‘127.0.0.1‘);
6 redis_client.auth(‘123456‘);
7 redis_client.on(‘error‘, function(error){
8 console.log(‘redis-error: ‘ + error);
9 });
10
11 //创建服务器
12 var http = require(‘http‘);
13 var url = require(‘url‘);
14 var fs = require(‘fs‘);
15 var ch = false;
16 var server = http.createServer(function (req, res) {
17 //获取请求参数
18 var objReqArg = url.parse(req.url, true).query;
19 ch = objReqArg.openid;
20 if (ch) {
21 redis_client.subscribe(ch, function(e){
22 console.log(‘channel: ‘+ ch);
23 });
24 };
25 //返回
26 res.writeHead(200, {‘Content-Type‘: ‘text/html‘});
27 res.end(html);
28
29 });
30 server.listen(1337, ‘www.zhangzhibin.com‘);
31
32 //创建服务器
33 var io = require(module_path + ‘socket.io‘).listen(server);
34 io.sockets.on(‘connection‘, function(socket){
35 socket.on(‘hello‘, function(data){
36 console.log(data);
37 });
38 socket.emit(‘hello‘, function(data){
39 console.log(data);
40 });
41 redis_client.on(‘message‘, function(error, msg){
42 socket.emit(‘emit‘, msg);
43 });
44 });
45
46 console.log(‘Server running at http://www.zhangzhibin.com:1337‘);
浏览器端html代码:
就是上边代码的第二行变量 var html=‘....‘
1 <html>
2 <head>
3 <meta charset="utf-8">
4 <title>微信接口</title>
5 <script src="http://cdn.bootcss.com/jquery/2.1.4/jquery.js"></script>
6 <script src="http://cdn.bootcss.com/socket.io/1.3.5/socket.io.js"></script>
7 </head>
8 <body>
9 <div id="voice"> 两秒钟同步一次:<br><br> </div>
10 <script type="text/javascript">
11 var voice = document.getElementById("voice");
12 var socket = io.connect("http://www.zhangzhibin.com:1337");
13 socket.on("hello", function(data){ console.log(data); socket.emit("hello", {"status":"ok"}); });
14 socket.on("emit", function(data){ var t = data+"<br>"; voice.innerHTML += t; socket.emit("emit", {"get":"data"}); });
15 </script>
16 </body>
17 </html>
微信端:
注意一点, 在语音回调函数中, 将语音识别的结果publish到某一个频道上即可
这时, 会触发上边第41行代码, 将文字发完浏览器端
下边是微信回调的代码:
1 public function voice()
2 {
3 // 每次发送消息都会post 来一份签名相关的数据
4 // $echostr = $this->checkSignature();
5 // exit($echostr);
6
7 preg_match(‘#<FromUserName><!\[CDATA\[([a-zA-Z0-9_]+)\]#‘, $GLOBALS[‘HTTP_RAW_POST_DATA‘], $matches1);
8 preg_match(‘#<Recognition><!\[CDATA\[([^\]]*)\]#‘, $GLOBALS[‘HTTP_RAW_POST_DATA‘], $matches2);
9 $openid = !empty($matches1[1]) ? $matches1[1] : ‘0‘;
10 $text = !empty($matches2[1]) ? $matches2[1] : ‘没听清...‘;
11
12 $objRedis = iredis::getInstance();
13 $objRedis->publish($openid, $text);
14
15 }
测试方法:
1. 关注我的微信公众号"平夏"
2. 发送消息"主播_username"
3. pc端打开 http://www.zhangzhibin.com/wechat/index/zhubolist
4. 点击你刚才输入的用户名, 进入你的对话页面
5. 对微信发送语音消息, 即可在刚才的浏览器页面看到语音识别结果
