項目背景：小程序中實現實時聊天功能
一、服務器域名配置
配置流程
配置參考URL：https://developers.weixin.qq.com/miniprogram/dev/api/api-network.html
二、nginx中配置反向代理加密websocket(wss)
upstream websocket{
hash $remote_addr consistent;
server 127.0.0.1:9090 weight=5 max_fails=3 fail_timeout=30s;
}
server {
listen 80;
server_name www.xxxx.cn;
rewrite ^(.*)$ https://$host$1 permanent;
}
server
{
listen 443;
server_name www.xxxx.cn;
ssl on;
root /home/wwwroot/yzcp;
index index.php index.html index.htm;
ssl_certificate /usr/local/nginx/conf/cert/1526060965511.pem;#這里是服務端證書路徑
ssl_certificate_key /usr/local/nginx/conf/cert/1526060965511.key;#這里是密鑰路徑
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;
#隱藏index.php
location / {
#index index.php;
deny 127.0.0.1;
if (!-e $request_filename) {
#一級目錄
rewrite ^(.*)$ /index.php?s=$1 last;
break;
}
#wss配置
client_max_body_size 100m;
proxy_redirect off;
proxy_pass http://websocket;#反向代理轉發地址
proxy_set_header Host $host;# http請求的主機域名
proxy_set_header X-Real-IP $remote_addr;# 遠程真實IP地址
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;#反向代理之后轉發之前的IP地址
proxy_read_timeout 604800s;#websocket心跳時間，默認是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;

}

}
三、安裝swoole
編譯安裝:
wget http://pecl.php.net/get/swoole-1.9.3.tgz //下載swoole tar -zvxf swoole-1.9.3.tgz //解壓swoole cd swoole-1.9.3/; //進入swoole /usr/local/php54/bin/phpize; //生成configure ./configure --with-php-config=/usr/local/php/bin/php-config make && make install //安裝 cd /phpstudy/server/php/lib/php/extensions/no-debug-non-zts-20121212 //查看是否安轉上了swoole.so (注意：此文件下邊都是你安裝的拓展) 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; //重啟nginx php -m; //查看phpinfo,這時候swoole拓展已經裝上了
四、服務器端運行程序
1、創建server.php放到項目的根目錄即可
<?php
//實例化一個swoole的websocket服務監聽本機的9501端口
$server = new swoole_websocket_server("服務器IP", 9090);
//只需要綁定要監聽的ip和端口。如果ip指定為127.0.0.1，則表示客戶端只能位于本機才能連接，其他計算機無法連接。
//端口這里指定為9090，可以通過netstat查看下該端口是否被占用。如果該端口被占用，可更改為其他端口，如9502，9503等。
$server->on('open', function (swoole_websocket_server $server, $request) {
echo "你好連接成功{$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只能運行在CLI模式下，所以不要試圖通過瀏覽器進行訪問，這樣是無效的,我們在命令行下面執行,注意一定要找到php的絕對路徑php server.php （這行代碼的意思是，把程序在服務器跑起來）
注意：php server.php命令運行后，下面的黑框關閉后將無法聊天。所以一般使用命令：nohup php server.php &
五、客戶端
1、網頁代碼
<!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">
內容：<textarea id="content"></textarea>
收信人：<input type="text" id="touser">
<input type="button" id="send-btn" value="發送">
<input type="button" id="close-btn" value="關閉">
</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);
})
socket.onmessage = function (p1) {
var htmlstr = "<div><p class='other-message'>"+p1.data+"</p></div>";
$("#show").append(htmlstr);
}
</script>
</html>
2、小程序端的代碼
Uitls/websocket.js：
var url = 'wss://www.xxx.cn';//服務器地址
function connect(user, func) {
wx.connectSocket({
url: url,
header: { 'content-type': 'application/json' },
success: function () {
console.log('websocket連接成功~')
},
fail: function () {
console.log('websocket連接失敗~')
}
})
wx.onSocketOpen(function (res) {
wx.showToast({
title: 'websocket已開通~',
icon: "success",
duration: 2000
})
//接受服務器消息
wx.onSocketMessage(func);//func回調可以拿到服務器返回的數據
});
wx.onSocketError(function (res) {
wx.showToast({
title: 'websocket連接失敗，請檢查！',
icon: "none",
duration: 2000
})
})
}
//發送消息
function send(msg) {
wx.sendSocketMessage({
data: msg
});
}
module.exports = {
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({
/**
* 頁面的初始數據
*/
data: {
newslist: [],
userInfo: {},
scrollTop: 0,
increase: false,//圖片添加區域隱藏
aniStyle: true,//動畫效果

previewImgList: []
},
/**

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

}
//調通接口
websocket.connect(this.data.userInfo, function (res) {
// console.log(JSON.parse(res.data))
var list = []
list = that.data.newslist
list.push(JSON.parse(res.data))
that.setData({
newslist: list
})
})
},
// 頁面卸載
onUnload() {
wx.closeSocket();
wx.showToast({
title: '連接已斷開~',
icon: "none",
duration: 2000
})
},
//事件處理函數
send: function () {
var flag = this
if (this.data.message.trim() == "") {
wx.showToast({
title: '消息不能為空哦~',
icon: "none",
duration: 2000
})
} else {
setTimeout(function () {
flag.setData({
increase: false
})
}, 500)
websocket.send('{ "content": "' + this.data.message + '", "date": "' + utils.formatTime(new Date()) + '","type":"text", "nickName": "' + this.data.userInfo.nickName + '", "avatarUrl": "' + this.data.userInfo.avatarUrl + '" }')
this.bottom()
}
},
//監聽input值的改變
bindChange(res) {
this.setData({
message: res.detail.value

cleanInput() {
//button會自動清空，所以不能再次清空而是應該給他設置目前的input值
this.setData({

increase: true,
aniStyle: true
})
},
//點擊空白隱藏message下選框
outbtn() {

})
},
//發送圖片
chooseImage() {
var that = this
wx.chooseImage({
count: 1, // 默認9
sizeType: ['original', 'compressed'], // 可以指定是原圖還是壓縮圖，默認二者都有
sourceType: ['album', 'camera'], // 可以指定來源是相冊還是相機，默認二者都有
success: function (res) {
// 返回選定照片的本地文件路徑列表，tempFilePath可以作為img標簽的src屬性顯示圖片
var tempFilePaths = res.tempFilePaths
// console.log(tempFilePaths)
wx.uploadFile({
url: 'wss://www.xxx.cn', //服務器地址
filePath: tempFilePaths[0],
name: 'file',
headers: {
'Content-Type': 'form-data'
},
success: function (res) {
if (res.data) {
that.setData({
increase: false
})
websocket.send('{"images":"' + res.data + '","date":"' + utils.formatTime(new Date()) + '","type":"image","nickName":"' + that.data.userInfo.nickName + '","avatarUrl":"' + that.data.userInfo.avatarUrl + '"}')
that.bottom()
}
}
})
}
})
},
//圖片預覽
previewImg(e) {
var that = this
//必須給對應的wxml的image標簽設置data-set=“圖片路徑”，否則接收不到
var res = e.target.dataset.src
var list = this.data.previewImgList //頁面的圖片集合數組
//判斷res在數組中是否存在，不存在則push到數組中, -1表示res不存在
if (list.indexOf(res) == -1) {
this.data.previewImgList.push(res)
}
wx.previewImage({
current: res, // 當前顯示圖片的http鏈接
urls: that.data.previewImgList // 需要預覽的圖片http鏈接列表
})
},
//聊天消息始終顯示最底端
bottom: function () {
var query = wx.createSelectorQuery()
query.select('#flag').boundingClientRect()
query.selectViewport().scrollOffset()
query.exec(function (res) {
wx.pageScrollTo({
scrollTop: res[0].bottom // #the-id節點的下邊界坐標
})
res[1].scrollTop // 顯示區域的豎直滾動位置
})
},
})
