PHP implements instant chat (based on Rongyun Communication)

Real-time chat in php (based on Rongyun Communication) is currently just a simple example.
Today I saw a very interesting project, an instant messaging tool. Although there are popular chat tools like QQ, it is still interesting to build one yourself.
This case is based on Rongyun Communication. The official website address is http://www.rongcloud.cn/. It has many functions. Since I don’t have a good-looking page, I directly use their plug-in. According to my observation, the plug-in only has the function of recent contacts. . Then let’s implement it according to the simple case first. If you like it, you can continue to study it yourself!
First, you need to register a Rongyun account --- and then create an instance yourself --- check various KEYs. Please follow the instructions on the official website for details. The example I gave is one of my test keys, which can be used directly. It's still a tp5 framework. I don't know how to configure the tp5 framework, so I won't say anything else. There is no use of a database to implement user information. It is a simple implementation of functions. It is mainly to demonstrate the functions for everyone. Please don’t complain.
Configure config.php for various keys<?php <br /> //Configuration file<br> return [<br> <br> 'APP_KEY' => 'e0x9wycfxxx5q',<br> 'APP_SECRET' => 'F7sI8rkLtv'<br> ]; The key they gave is so short. Do you have it? Let’s continue. I downloaded the official SDK and introduced it to the extend file. It can be called directly. Let’s start the main part, the main method of the chat page:
Index.php<?php <br /> namespace appindexcontroller;<br> <br> use rongyunServerAPI;<br> use thinkController;<br> <br> class Index extends Controller<br> {<br> Public function _initialize()<br> {<br> If (Empty (Cookie ('UID'))) {<br>                $this->redirect( url('login/index') );<br>          }<br> }<br> <br> //Chat main method<br> Public function index()<br> {<br> ​​​​$appKey = config('APP_KEY');<br>         $appSecret = config('APP_SECRET');<br> <br>         $rongYun = new ServerAPI( $appKey, $appSecret);<br> <br>          $tx = "http://www.tk.com/static/images/1.jpg";<br> If( 2 == cookie('uid') ){<br>              $tx = "http://www.tk.com/static/images/2.jpg";<br>          }<br>         $token = $rongYun->getToken( cookie('uid'), cookie('uname'), $tx );<br> <br>         $token = json_decode( $token, true )['token'];<br>           $this->assign([<br> ‘token’ => $token<br> ]);<br>           return $this->fetch();<br> }<br> <br> //All user information<br> Public function userInfo()<br> {<br>          $return['userlist'] = [<br>                                                                                                                                                                                                              ['id' => 2, 'name' => '李思', 'portraitUri' => 'http://www.tk.com/static/images/2.jpg']<br> ];<br>           return json( $return );<br> }<br> <br> //Login user information<br> Public function onLine()<br> {<br>         $return['data'] = [<br>                                                                                                                                                  ['id' => '1', 'status' => true],<br> ['id' => '2', 'status' => true]<br> ];<br>           return json( $return );<br> }<br> }I have written all kinds of codes to death, mainly to demonstrate the effect. Okay, for the rest of the code, you can go to my github to download it and go to the official website to compare it. I mainly demonstrate how to run it. Take a look at login.php:<?php <br /> namespace appindexcontroller;<br> <br> use thinkController;<br> <br> class Login extends Controller<br> {<br> Public function index()<br> {<br>            return $this->fetch();<br> }<br> <br> Public function doLogin()<br> {<br>          $param = input('param.');<br> <br> If ('Zhang San' == $ Param ['uname']) {<br>                cookie('uid', 1);<br> Cookie('uname', 'Zhang San');<br>           }else if('李思'==$param['uname']){<br> <br> Cookie('uid', 2);<br> Cookie('uname', '李思');<br>         }<br> <br>          $this->redirect( url('index/index') );<br> }<br> } Haha, my login is just to distinguish users (this is not the case for real projects!). As you can see, one user is Zhang San and the other user is Li Si. Just enter the password randomly. Let’s take a look at the demonstration effect:
First visit the homepage. If you are not logged in, you will be redirected to log in:


If you are using Zhang San to log in, remember: Zhang San’s ID is 1, which is very important! The username is correct and the password is entered randomly. After logging in, the page is as follows:

Enter the ID of the session, which is the user ID. Let’s talk to Li Si, Li Si is 2, and then click Set Session, the following page will pop up:

Let’s start chatting:


Then reopen a browser, it must be another browser! Log in, use Li Si to log in, you will see:

I saw Zhang San sent you a message, open it and take a look:

You can also reply:

Haha, isn’t it interesting? Of course, I have only implemented the simplest functions now, and those who are interested can continue to study!
