微信网页支付接口的主逻辑封装

monkeye · 发表于 2015-10-15 10:16:30

Part1 前提条件
使用微信支付必须拥有以下字段, 其中partnerId，partnerKey和paySignKey需要开通微信支付方可获得：

appId - 公众号身份的唯一标识
appSecret - 公众平台接口API密钥
partnerId - 财付通商户身份的标识
partnerKey - 财付通商户权限密钥 Key
paySignKey - 公众号支付请求中用于加密的密钥Key,对应于支付场景中的appKey值
拿到以上字段后在WXConstant.php中进行配置。

Part2 接口封装
微信支付接口文档：使用公众号发起支付请求

1. web页面调用微信支付
调用JS API支付接口getBrandWCPayRequest()能够调出微信支付的页面：

/

/ js 调用微信支付页面
WeixinJSBridge.invoke('getBrandWCPayRequest', {
appId: appId, // 公众号id
timeStamp: timeStamp, // 时间戳
nonceStr: nonceStr, // 随机字符串
package: package, // 订单详情扩展字符串
signType: signType, // 签名方式
paySign: paySign // 签名
}, function(res) {
if (res.err_msg != 'get_brand_wcpay_request:ok') {
alert('支付失败!');
} else {
alert('支付成功!');
}
});

复制代码

以上代码中，涉及到appId，timeStamp，nonceStr，package，signType和paySign六个参数，其中主要工作在于生成订单详情扩展字符串package和签名paySign：

1.1 生成订单详情(package)扩展字符串

$wxpay = WXPay::factory();
$package = $wxpay->getPackage($orderData);

复制代码

订单详情信息包含有发起支付请求的商户信息和交易信息，重点看其中的3个参数：

out_trade_no - 商户订单号此订单号由调用者即商户自己生成，在商户内全局唯一来标识该比交易, 微信后台通知商户支付成功时，会将此订单号发送给商户
total_fee - 订单总金额此次交易的总金额
notify_url - 通知 URL 此url由商户提供，在支付完成后微信将通过此url通知商户订单的支付
1.2 生成支付签名
$paySign = $wxpay->getPaySign();
2. 接收支付结果通知
用户在成功完成支付后,微信后台通知( POST)商户服务器(notify_url)支付结果, 在微信发过来的数据中重点关注以下参数值：

total_fee - 订单总金额
transaction_id - 订单号, 由微信方生成
out_trade_no －商户订单号，1.1中提到的商户订单号
time_end －支付完成时间
sign －签名
接收到微信通知后，在验证签名后，就可以根据out_trade_no对相应的订单进行状态更新了。

WXPay::factory()->receivePayNotify();

复制代码

3. 发货通知
在收到支付通知后,商户要按时发货,并使用发货通知接口将相关信息同步到微信后台。若微信平台在规定时间内没有收到,将视作发货超时处理。发货时间限制:虚拟、服务类 24 小时内,实物类 72小时内。

WXPay::factory()->deliverNotify($postData)

复制代码

4. 查询订单
商户在预期时间内未收到支付结果通知，可以通过此接口查询订单的支付状态

WXPay::factory()->orderQuery($postData)

复制代码

5. 接收告警通知
微信后台会向商户推送告警通知,包括发货延迟、调用失败、通知失败等情况

WXPay::factory()->receiveAlert($postXML)

复制代码

6. 接收用户维权信息通知
接入微信支付的商户都必须接入用户维权系统，微信将用户投诉内容通过此api发送给商户

WXPay::factory()->receivePayFeedback($postXML = '')

复制代码

7. 更新用户维权处理结果
商户可以通过此api调用，标记客户的投诉处理状态

WXPay::factory()->updatePayFeedback(($openId, $feedbackId))

复制代码
