⼩程序实现即时通信聊天功能的实例代码项⽬背景：⼩程序中实现实时聊天功能
⼀、服务器域名配置
配置流程
⼆、nginx中配置反向代理加密websocket(wss)
upstream websocket{
hash $remote_addr consistent;
server 127.0.0.1:9090 weight=5 max_fails=3 fail_timeout=30s;
}
server {
listen 80;
server_;
rewrite ^(.*)$ $host$1 permanent;
}
server
{
listen 443;
server_;
ssl on;
root /home/wwwroot/yzcp;
index index.php index.html index.htm;
ssl_certificate /usr/local/nginx/conf/cert/1526060965511.pem;#这⾥是服务端证书路径
ssl_certificate_key /usr/local/nginx/conf/cert/1526060965511.key;#这⾥是密钥路径
ssl_session_timeout 5m;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_verify_client off;
#隐藏index.php
location / {
#index index.php;
deny 127.0.0.1;
if (!-e $request_filename) {
#⼀级⽬录
rewrite ^(.*)$ /index.php?s=$1 last;
break;
}
#wss配置
client_max_body_size 100m;
proxy_redirect off;
proxy_pass websocket;#反向代理转发地址
proxy_set_header Host $host;# http请求的主机域名
proxy_set_header X-Real-IP $remote_addr;# 远程真实IP地址
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;#反向代理之后转发之前的IP地址
proxy_read_timeout 604800s;#websocket⼼跳时间，默认是60s
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
}
location ~ .+\.php {
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;
include fastcgi_params;
set $path_info "";
set $real_script_name $fastcgi_script_name;
if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
set $real_script_name $1;
set $path_info $2;
}
fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
fastcgi_param SCRIPT_NAME $real_script_name;
fastcgi_param PATH_INFO $path_info;

}
access_log /home/wwwlogs/www1537ucn.log;
}
三、安装swoole
编译安装:
wget pecl.php/get/swoole-1.  //下载swoole
tar -zvxf swoole-1.  //解压swoole
cd swoole-1.9.3/;  //进⼊swoole
/usr/local/php54/bin/phpize;  //⽣成configure
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install  //安装
cd /phpstudy/server/php/lib/php/extensions/no-debug-non-zts-20121212 //查看是否安转上了swoole.so (注意：此⽂件下边都是你安装的拓展)
vim /phpstudy/server/php/etc/php.ini  //在php.ini添加extension=swoole.so加⼊到⽂件最后⼀⾏
lnmp restart; //重启nginx
php -m; //查看phpinfo，这时候swoole拓展已经装上了
四、服务器端运⾏程序
1、创建server.php放到项⽬的根⽬录即可
<?php
//实例化⼀个swoole的websocket服务监听本机的9501端⼝
$server = new swoole_websocket_server("服务器IP", 9090);
/
/只需要绑定要监听的ip和端⼝。如果ip指定为127.0.0.1，则表⽰客户端只能位于本机才能连接，其他计算机⽆法连接。
//端⼝这⾥指定为9090，可以通过netstat查看下该端⼝是否被占⽤。如果该端⼝被占⽤，可更改为其他端⼝，如9502，9503等。
$server->on('open', function (swoole_websocket_server $server, $request) {
echo "你好连接成功{$request->fd}\n";
});
$server->on('message', function (swoole_websocket_server $server, $frame) {
foreach($server->connections as $key => $fd) {
$user_message = $frame->data;
$server->push($fd, $user_message);
}
});
$server->on('close', function ($ser, $fd) {
echo "client {$fd} closed\n";
});
$server->start();
>
2、由于swoole_server只能运⾏在CLI模式下，所以不要试图通过浏览器进⾏访问，这样是⽆效的，我们在命令⾏下⾯执⾏，注意⼀定要到php的绝对路径php  server.php  （这⾏代码的意思是，把程序在服务器跑起来）
注意：php server.php命令运⾏后，下⾯的⿊框关闭后将⽆法聊天。所以⼀般使⽤命令：nohup php server.php &
五、客户端
1、⽹页代码
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>聊天</title>
<style type="text/css">
#show{
width: 600px;
height: 300px;
overflow-y: scroll;
}
.my-message{
background-color: rgba(105, 105, 105, 0.64);
color: #9e0505;
width: 200px;
float: right;
padding: 10px;
}
.other-message{
background-color: rgba(105, 105, 105, 0.64);
color: #9e0505;
width: 200px;
float: left;
padding: 10px;
}
</style>
</head>
<body>
<div id="show"></div>
<div class="panel">
内容：<textarea id="content"></textarea>
收信⼈：<input type="text" id="touser">
<input type="button" id="send-btn" value="发送">
<input type="button" id="close-btn" value="关闭">
</div>
</body>
<script src="__PUBLIC__/js/jquery-1.10.2.min.js" charset="utf-8"></script> <script type="text/javascript">
var socket = new WebSocket("wss://域名");
$("#close-btn").click(function () {
socket.close();
})
$("#send-btn").click(function () {
var touser = $("#touser").val();
var content = $("#content").val();
var htmlstr = "<div><p class='my-message'>我："+content+"</p></div>";  $("#show").append(htmlstr);
socket.send(content+"@"+touser);
})
var htmlstr = "<div><p class='other-message'>"+p1.data+"</p></div>";  $("#show").append(htmlstr);
}
</script>
</html>
2、⼩程序端的代码
Uitls/websocket.js：
var url = 'wss://';//服务器地址
function connect(user, func) {
url: url,
header: { 'content-type': 'application/json' },
success: function () {
console.log('websocket连接成功~')
},
fail: function () {
console.log('websocket连接失败~')
}
})
wx.showToast({
title: 'websocket已开通~',
icon: "success",
duration: 2000
})
//接受服务器消息
wx.showToast({
title: 'websocket连接失败，请检查！',
icon: "none",
duration: 2000
})
})
}
//发送消息
function send(msg) {
wx.sendSocketMessage({
data: msg
});
}
connect: connect,
send: send
}
JS：
// pages/socks/socks.js
const app = getApp()
var websocket = require('../../utils/websocket.js');
var utils = require('../../utils/util.js');
Page({

},
/**

onLoad: function () {
var that = this
if (app.globalData.userInfo) {
this.setData({

})
}
/
/调通接⼝
// console.log(JSON.parse(res.data))
var list = []
list = wslist
list.push(JSON.parse(res.data))
that.setData({

})
},
/
/ 页⾯卸载
onUnload() {
wx.closeSocket();
wx.showToast({

})
},
//事件处理函数
send: function () {
var flag = this
if (im() == "") {
wx.showToast({
title: '消息不能为空哦~',
icon: "none",
duration: 2000
})
} else {
setTimeout(function () {
flag.setData({
increase: false
})
}, 500)
websocket.send('{ "content": "' + ssage + '", "date": "' + utils.formatTime(new Date()) + '","type":"text", "nickName": "' + this.data.userInfo.nickName + '", "avatarUrl": "' + this.data.userInfo.avatarUrl + '" }')  this.bottom()
}
},
//监听input值的改变
bindChange(res) {
this.setData({
message: res.detail.value
})
},
cleanInput() {
//button会⾃动清空，所以不能再次清空⽽是应该给他设置⽬前的input值
this.setData({
message: ssage
})
},
increase() {
this.setData({
increase: true,
aniStyle: true
})
},
//点击空⽩隐藏message下选框
outbtn() {
this.setData({
increase: false,
aniStyle: true
})
},
//发送图⽚
chooseImage() {
var that = this
wx.chooseImage({
count: 1, // 默认9
sizeType: ['original', 'compressed'], // 可以指定是原图还是压缩图，默认⼆者都有
sourceType: ['album', 'camera'], // 可以指定来源是相册还是相机，默认⼆者都有
success: function (res) {
// 返回选定照⽚的本地⽂件路径列表，tempFilePath可以作为img标签的src属性显⽰图⽚
var tempFilePaths = pFilePaths
// console.log(tempFilePaths)
wx.uploadFile({
url: 'wss://', //服务器地址
filePath: tempFilePaths[0],
name: 'file',
headers: {
'Content-Type': 'form-data'
},

//判断res在数组中是否存在，不存在则push到数组中, -1表⽰res不存在
if (list.indexOf(res) == -1) {

}
wx.previewImage({
