微信 SDK

配置公众号 && 商户

// 公众号配置
define('APPID', 'your appid');
define('APPSECRET', 'your appsecret');
// 商户配置
define('MCHID', 'your mchid');
define('MCHKEY', 'your mchkey');
// 支付成功通知 URL
define('NOTIFY_URL', 'http://example.com/your_are_notify.php');

一、获取公众号 AccessToken

use Thenbsp\Wechat\Wechat;
$o = new Wechat(APPID, APPSECRET);
$accessToken = $o->getAccessToken();
var_dump($accessToken);

二、获取公众号 Ticket

use Thenbsp\Wechat\Wechat;
$o = new Wechat(APPID, APPSECRET);
$ticket = $o->getTicket();
var_dump($ticket);

三、获取公众号 JSSDK 配置

use Thenbsp\Wechat\Config;
use Thenbsp\Wechat\Wechat;
$wechat = new Wechat(APPID, APPSECRET);
$apis = array('onMenuShareTimeline', 'onMenuShareAppMessage');
$configJSON = Config::getJssdk($wechat, $apis, $debug = true, $asArray = false);

<script>
wx.config(<?php echo $configJSON; ?>);
</script>

四、获取微信服务器 IP

use Thenbsp\Wechat\Wechat;
$o = new Wechat(APPID, APPSECRET);
$ip = $o->getServerIp();
var_dump($ip);

五、网页授权获取用户信息

use Thenbsp\Wechat\OAuth;
use Thenbsp\Wechat\Exception\OAuthException;
$o = new OAuth(APPID, APPSECRET);
$callbackUrl = 'Your callback url';
if( !isset($_GET['code']) ) {
 $o->authorize($$callbackUrl, 'snsapi_userinfo');
} else {
 /**
 * 根据 code 换取 Token
 */
 try {
 $token = $o->getToken($_GET['code']);
 } catch (OAuthException $e) {
 exit($e->getMessage());
 }
 /**
 * 根据 Token 获取用户信息
 */
 $user = $o->getUser($token);
 
 var_dump($user);
}

六、微信支付

WeixinJSBridge invoke 示例:

use Thenbsp\Wechat\OAuth;
use Thenbsp\Wechat\Config;
use Thenbsp\Wechat\Util\Bag;
use Thenbsp\Wechat\Util\Util;
use Thenbsp\Wechat\Payment\Unifiedorder;
/**
 * 第 1 步:配置商品信息
 */
$bag = new Bag();
$bag->set('appid', APPID);
$bag->set('mch_id', MCHID);
$bag->set('notify_url', NOTIFY_URL);
$bag->set('body', 'iphone 6 plus');
$bag->set('out_trade_no', date('YmdHis').mt_rand(10000, 99999));
$bag->set('total_fee', 1);
$bag->set('openid', $_SESSION['openid']);
/**
 * 第 2 步:统一下单
 */
$unifiedorder = new Unifiedorder($bag, MCHKEY);
/**
 * 第 3 步:生成支付配置文件
 */
$configJSON = Config::getPaymentConfig($unifiedorder, $asArray = false);

var WXPayment = function() {
 if( typeof WeixinJSBridge === 'undefined' ) {
 alert('请在微信在打开页面!');
 return false;
 }
 WeixinJSBridge.invoke('getBrandWCPayRequest', <?php echo $configJSON; ?>, function(res) {
 switch(res.err_msg) {
 case 'get_brand_wcpay_request:cancel':
 alert('用户取消支付!');
 break;
 case 'get_brand_wcpay_request:fail':
 alert('支付失败!('+res.err_desc+')');
 break;
 case 'get_brand_wcpay_request:ok':
 alert('支付成功!');
 break;
 default:
 alert(JSON.stringify(res));
 break;
 }
 });
}

<button type="button" onclick="WXPayment()">支付 \<?php echo ($bag->get('total_fee') / 100); ?> 元</button>

扫码支付示例:

use Thenbsp\Wechat\Config;
use Thenbsp\Wechat\Util\Bag;
use Thenbsp\Wechat\Payment\Unifiedorder;
/**
 * 配置订单信息
 */
$bag = new Bag();
$bag->set('appid', APPID);
$bag->set('mch_id', MCHID);
$bag->set('notify_url', NOTIFY_URL);
$bag->set('body', 'iphone 6 plus');
$bag->set('out_trade_no', date('YmdHis').mt_rand(10000, 99999));
$bag->set('total_fee', 1); // 单位为 "分"
$bag->set('trade_type', 'NATIVE'); // NATIVE 时不需要 Openid
/**
 * 统一下单
 */
$unifiedorder = new Unifiedorder($bag, MCHKEY);
/**
 * 获取支付 URL(模式 2)
 */
$payurl = Config::getTemporaryPayurl($unifiedorder);
