Many small programs have been developed. Each time, we have to turn over the documents and find the previous project to copy it,
It takes time and trouble. In order to facilitate the development of small programs, we simply build our own wheels,
Integration of small programs (WeChat, QQ, Baidu, byte beating, Alipay) related development.

!! Please be familiar with the relevant applet documentation first!! Please have basic debug ging ability!!

characteristic

• Rich expansion, support for WeChat, QQ, Baidu, byte beating, Alipay (to be perfect) applet.
• Comply with PSR standard and integrate with your framework conveniently
• The file structure is clear, and each class is encapsulated and extended separately, which is convenient for separate use

Supported applets

1. Wechat

2,QQ(QQ)

3. Baidu

4. Byte jitter

5, Alipay (Alipay)

Installation( GitHub)

composer require fengkui/xcx

Improve relevant configuration

# Wechat applet configuration
$wechatConfig = [
    'appid' => '',
    'secret' => '',
];
# QQ applet configuration
$qqConfig = [
    'appid' => '',
    'secret' => '',
];
# Baidu applet configuration
$baiduConfig = [
    'appid' => '',
    'appkey' => '',
    'secret' => '',
];
# Byte runout applet configuration
$bytedanceConfig = [
    'appid' => '',
    'secret' => '',
];
# Alipay applet configuration
$alipayConfig = [
    'app_id' => '', // Application ID allocated to developers by Alipay
    'public_key' => '', // Please fill in the Alipay public key.
    'private_key' => '', // Please fill in the developer's private key, go to the beginning, go to the end and enter
];

instructions

Use alone

$xcx = new \fengkui\Xcx\Wechat($wechatConfig); // WeChat
$xcx = new \fengkui\Xcx\Qq($qqConfig); // QQ
$xcx = new \fengkui\Xcx\Baidu($baiduConfig); // Baidu
$xcx = new \fengkui\Xcx\Bytedance($bytedanceConfig); // Byte runout
$xcx = new \fengkui\Xcx\Alipay($alipayConfig); // Alipay
