EasyWeChat and PHP develop WeChat mini-program tourist guide function implementation skills
[Introduction]
With the rapid development of the mobile Internet, WeChat mini-programs have become the choice of more and more enterprises and individuals . As a fast and concise application, mini programs are gradually equipped with more functions and services, among which the tourist guide function is a very popular service. This article will introduce how to use EasyWeChat and PHP to develop the tourist navigation function of the WeChat applet, and provide relevant code examples.
[Technical Preparation]
To realize the tourist guide function, we need the following technical preparations:
[Implementation steps]
Step 1: Create a mini program
First, we need to create a new mini program on the official WeChat mini program platform. During the creation process, we need to obtain the AppID and AppSecret of the applet. This information will be used in subsequent steps.
Step 2: Install EasyWeChat
Use Composer to install EasyWeChat, which can be executed in the command line through the following command:
composer require overtrue/wechat
Step 3: Configure EasyWeChat
Create a config.php file in the project and fill in the EasyWeChat configuration information. The following is a sample configuration:
<?php return [ 'app_id' => 'your-app-id', 'secret' => 'your-secret', 'response_type' => 'array', ];
Step 4: Create a PHP script
Create an index.php file and write the following source code:
<?php require 'vendor/autoload.php'; use EasyWeChatFactory; $config = require 'config.php'; $app = Factory::miniProgram($config); $app->server->push(function ($message) { switch ($message['MsgType']) { case 'text': return "欢迎使用游客导览功能!"; break; case 'location': // 处理位置信息 return "你的位置:" . $message['Location_X'] . "," . $message['Location_Y']; break; default: return "未知消息类型"; break; } }); $response = $app->server->serve(); $response->send();
Step 5: Deploy code
Upload the index.php file to the server, and use nginx or other web servers to configure the domain name and path.
Step 6: Mini Program Development
Write the following code in the js file of the page:
Page({ data: { location: '' }, onLoad: function() { wx.getLocation({ type: 'wgs84', success: (res) => { const latitude = res.latitude const longitude = res.longitude this.setData({ location: `经度:${longitude},纬度:${latitude}` }) } }) } })
wx.getLocation
method to obtain the user’s location information , and display the location information on the page. [Summary]
By using EasyWeChat and PHP to develop the tourist navigation function of the WeChat applet, we can implement this function simply and efficiently. This article provides implementation steps and related code examples, hoping to be helpful to readers in the development of WeChat mini programs. Of course, the tourist guide function is only a small part of the WeChat mini program, and developers can expand and optimize more functions according to their own needs and actual conditions.
