Re-write and encapsulate Baidu Payment (Baidu Smart Mini Program Payment)
Jul 17, 2021 pm 03:38 PM
Recently due to project reconstruction, Baidu Payment has been rewritten and encapsulated. In this rewrite, signature processing and user refunds have been added to facilitate subsequent development and use.
Due to the upgrade of Baidu e-commerce open platform, the payment function has been moved to the smart mini program. The specific application process is: Baidu Cashier Payment Activation Guide, (https://smartprogram.baidu.com/docs/operations /transform/pay/)
(Note: In the payment service, the service phone number should be filled in with the mobile phone number reserved by the bank. If it is incorrectly filled in, [bank reserved mobile phone number format verification failed] will be reported)
Baidu Payment Document: Baidu Cashier Interface 2.0 (https://smartprogram.baidu.com/docs/develop/function/tune_up_2.0/)
1. After the application is approved, fill in the Baidu payment related information Configuration:
$config = array(
'deal_id' => '', // 百度收銀臺(tái)的財(cái)務(wù)結(jié)算憑證
'app_key' => '', // 表示應(yīng)用身份的唯一ID
'private_key' => '', // 私鑰原始字符串
'public_key' => '', // 平臺(tái)公鑰
'notify_url' => '', // 支付回調(diào)地址
);2. Call the encapsulated payment method and pass the returned information to Baidu Mini Program
<?php
include './BaiduPay.php';
$baidupay = new \feng\BaiduPay($config);
$order_sn = time().rand(1000,9999);
$order = array(
'body' => '測(cè)試商品', // 產(chǎn)品描述
'total_amount' => '1', // 訂單金額（分）
'order_sn' => $order_sn, // 訂單編號(hào)
);
$re = $baidupay->xcxPay($order);
die(json_encode($re)); // JSON化直接返回小程序客戶端

public static function xcxPay($order)

}3. Baidu Intelligence Use of mini program
SWAN
<view class="wrap">
<view class="card-area">
<button bind:tap="requestPolymerPayment" type="primary" hover-stop-propagation="true">支付0.01元</button>
</view>
</view>
HTMLJS
Page({
requestPolymerPayment(e) {
swan.request({
url: 'https://mbd.baidu.com/xxx', // 僅為示例，并非真實(shí)的接口地址，開發(fā)者從真實(shí)接口獲取orderInfo的值
success: res => {

let data = res.data;
if (data.errno !== 0) {
console.log('create order err', data);
return;
}
swan.requestPolymerPayment({

success: res => {
swan.showToast({

});
console.log('pay success', res);
},
fail: err => {

},
fail: err => {
swan.showToast({

});
console.log('create order fail', err);
}
});
}
});4. Payment callback
<?php
include './BaiduPay.php';
$baidupay = new \feng\BaiduPay($config);
$re = $baidupay->notify();
if ($re) {
// 這里回調(diào)處理訂單操作
// 以驗(yàn)證返回支付成功后的信息，可直接對(duì)訂單進(jìn)行操作，已通知微信支付成功
$baidupay->success(); // 支付返還成功，通知結(jié)果
} else {
// 支付失敗
$baidupay->error(); // 支付失敗，返回狀態(tài)（無論支付成功與否都需要通知百度）
