With the rapid development of mobile Internet technology, users' demand for instant messaging and real-time interaction has gradually increased. As an important protocol for real-time communication on the Web, the WebSocket protocol has the characteristics of full-duplex communication, real-time push, and low latency, and has become the preferred protocol in real-time interaction scenarios. Therefore, in web development, we need to master how to use WebSocket to achieve real-time communication.
In PHP, we can use the Swoole extension to implement WebSocket functionality. However, it takes a lot of time and effort to deploy and set up Swoole. For some developers who are unfamiliar with Swoole, the learning cost is also relatively high.
Today, we are going to introduce how to use WebSocket in ThinkPHP6.
1. Install the extension
Before using WebSocket in ThinkPHP6, we need to install the topthink/thinker
extension.
composer require topthink/thinker:dev-master
topthink/thinker
is a command line tool for running PHP code and managing asynchronous tasks in ThinkPHP6.
2. Configure WebSocket
We need to configure WebSocket in the project configuration file config/socket.php
.
<?php return [ // WebSocket服務器地址,使用內(nèi)網(wǎng)穿透時填寫內(nèi)網(wǎng)地址 'server' => '127.0.0.1:9501', // WebSocket的應用類,需要實現(xiàn) hinkworkerServer 接口 'worker_class' => 'appcontrollerWebSocket', ];
We need to specify the address of server
and the class worker_class
that implements the Server
interface. Here we will implement the controller class of the WebSocket function. Name it WebSocket
and place it in the appcontroller
directory.
3. Implement WebSocket
We create a controller named WebSocket
in the appcontroller
directory and implement in the controller Server
interface.
<?php namespace appcontroller; use thinkworkerServer; class WebSocket implements Server { protected $socket = 'websocket://127.0.0.1:9501'; public function onMessage($connection, $data) { foreach ($this->worker->connections as $conn) { $conn->send('user ' . $connection->id . ' said: ' . $data); } } public function onConnect($connection) { echo "new connection from ip " . $connection->getRemoteIp() . " "; } public function onClose($connection) { echo "connection closed: " . $connection->id . " "; } public function onWorkerStart($worker) { // 初始化 } }
In the WebSocket
controller class, we need to implement onMessage
, onConnect
, onClose
and onWorkerStart
Four methods.
onMessage
: When the client sends data, theonMessage
method will be triggered. The parameter$connection
represents the client’s connection object.$data
represents the data sent by the client.onConnect
: TheonConnect
method will be triggered when the client connects. The parameter$connection
represents the client's connection object.onClose
: TheonClose
method will be triggered when the client disconnects. The parameter$connection
represents the client's connection object.onWorkerStart
: TheonWorkerStart
method will be triggered when the worker process starts. The parameter$worker
represents the object of the current worker process.
4. Run WebSocket
After configuring WebSocket, we can use the think
command to start WebSocket.
php think worker:start
The above command will start a WebSocket service and output the running log on the console.
5. Test WebSocket
After WebSocket is implemented, we can use the WebSocket client for testing. We can use the Chrome
browser and install the Simple WebSocket Client
plug-in for testing. Enter the address of the WebSocket server in the plug-in and click Connect to start using WebSocket communication.
In Simple WebSocket Client
, we can enter characters and click send, and we can see the output log in the background console, indicating that WebSocket communication can work normally.
Summary
In this article, we introduced how to use WebSocket in ThinkPHP6. The WebSocket protocol is the preferred protocol for real-time communication and its use scenarios are very wide. In actual development, we can use WebSocket to easily implement real-time communication functions according to needs and improve user experience.
The above is the detailed content of Using WebSocket in ThinkPHP6. For more information, please follow other related articles on the PHP Chinese website!

The settings.json file is located in the user-level or workspace-level path and is used to customize VSCode settings. 1. User-level path: Windows is C:\Users\\AppData\Roaming\Code\User\settings.json, macOS is /Users//Library/ApplicationSupport/Code/User/settings.json, Linux is /home//.config/Code/User/settings.json; 2. Workspace-level path: .vscode/settings in the project root directory

Use datetime.strptime() to convert date strings into datetime object. 1. Basic usage: parse "2023-10-05" as datetime object through "%Y-%m-%d"; 2. Supports multiple formats such as "%m/%d/%Y" to parse American dates, "%d/%m/%Y" to parse British dates, "%b%d,%Y%I:%M%p" to parse time with AM/PM; 3. Use dateutil.parser.parse() to automatically infer unknown formats; 4. Use .d

Yes, a common CSS drop-down menu can be implemented through pure HTML and CSS without JavaScript. 1. Use nested ul and li to build a menu structure; 2. Use the:hover pseudo-class to control the display and hiding of pull-down content; 3. Set position:relative for parent li, and the submenu is positioned using position:absolute; 4. The submenu defaults to display:none, which becomes display:block when hovered; 5. Multi-level pull-down can be achieved through nesting, combined with transition, and add fade-in animations, and adapted to mobile terminals with media queries. The entire solution is simple and does not require JavaScript support, which is suitable for large

itertools.combinations is used to generate all non-repetitive combinations (order irrelevant) that selects a specified number of elements from the iterable object. Its usage includes: 1. Select 2 element combinations from the list, such as ('A','B'), ('A','C'), etc., to avoid repeated order; 2. Take 3 character combinations of strings, such as "abc" and "abd", which are suitable for subsequence generation; 3. Find the combinations where the sum of two numbers is equal to the target value, such as 1 5=6, simplify the double loop logic; the difference between combinations and arrangement lies in whether the order is important, combinations regard AB and BA as the same, while permutations are regarded as different;

Python is an efficient tool to implement ETL processes. 1. Data extraction: Data can be extracted from databases, APIs, files and other sources through pandas, sqlalchemy, requests and other libraries; 2. Data conversion: Use pandas for cleaning, type conversion, association, aggregation and other operations to ensure data quality and optimize performance; 3. Data loading: Use pandas' to_sql method or cloud platform SDK to write data to the target system, pay attention to writing methods and batch processing; 4. Tool recommendations: Airflow, Dagster, Prefect are used for process scheduling and management, combining log alarms and virtual environments to improve stability and maintainability.

@property decorator is used to convert methods into properties to implement the reading, setting and deletion control of properties. 1. Basic usage: define read-only attributes through @property, such as area calculated based on radius and accessed directly; 2. Advanced usage: use @name.setter and @name.deleter to implement attribute assignment verification and deletion operations; 3. Practical application: perform data verification in setters, such as BankAccount to ensure that the balance is not negative; 4. Naming specification: internal variables are prefixed, property method names are consistent with attributes, and unified access control is used to improve code security and maintainability.

fixture is a function used to provide preset environment or data for tests. 1. Use the @pytest.fixture decorator to define fixture; 2. Inject fixture in parameter form in the test function; 3. Execute setup before yield, and then teardown; 4. Control scope through scope parameters, such as function, module, etc.; 5. Place the shared fixture in conftest.py to achieve cross-file sharing, thereby improving the maintainability and reusability of tests.

Use the uuid module to obtain the MAC address of the first network card of the machine across the platform, without the need for a third-party library, and convert it into a standard format through uuid.getnode(); 2. Use subprocess to call system commands such as ipconfig or ifconfig, and combine it with regular extraction of all network card MAC addresses, which is suitable for scenarios where multiple network card information needs to be obtained; 3. Use the third-party library getmac, call get_mac_address() after installation to obtain the MAC, which supports query by interface or IP, but requires additional dependencies; in summary, if no external library is needed, the uuid method is recommended. If you need to flexibly obtain multi-network card information, you can use the subprocess solution to allow you to install the dependency getma.
