前面已經(jīng)寫了手機(jī)APP支付寶支付，今天再把手機(jī)APP微信支付補(bǔ)上，前期的準(zhǔn)備工作在這里就不多說了，可以參考微信支付開發(fā)文檔，一定要仔細(xì)閱讀開發(fā)文檔，可以讓你少踩點(diǎn)坑；準(zhǔn)備工作完成后就是配置參數(shù),調(diào)用統(tǒng)一下單接口,支付后異步回調(diào)三部曲啦；
1.我封裝好的一個(gè)支付類文件,多余的東西都去除掉了,并且把配置參數(shù)放到了這個(gè)支付類中,只需要修改Weixinpayandroid方法內(nèi)的幾個(gè)參數(shù)就可以直接復(fù)制使用:
class Wxpayandroid

//參數(shù)配置
public $config = array(
'appid' => "", /*微信開放平臺(tái)上的應(yīng)用id*/
'mch_id' => "", /*微信申請成功之后郵件中的商戶id*/
'api_key' => "", /*在微信商戶平臺(tái)上自己設(shè)定的api密鑰 32位*/
);
//服務(wù)器異步通知頁面路徑(必填)
public $notify_url = '';
//商戶訂單號(hào)(必填，商戶網(wǎng)站訂單系統(tǒng)中唯一訂單號(hào))
public $out_trade_no = '';
//商品描述(必填，不填則為商品名稱)
public $body = '';
//付款金額(必填)
public $total_fee = 0;
//自定義超時(shí)(選填，支持dhmc)
public $time_expire = '';
private $WxPayHelper;
public function Weixinpayandroid($total_fee,$tade_no)
{
$this->total_fee = intval($total_fee * 100);//訂單的金額 1元
$this->out_trade_no = $tade_no;// date('YmdHis') . substr(time(), - 5) . substr(microtime(), 2, 5) . sprintf('%02d', rand(0, 99));//訂單號(hào)
$this->body = 'wxpay';//支付描述信息

2.創(chuàng)建控制器定義統(tǒng)一下單接口和支付后的異步回調(diào)接口:
//異步通知接口
public function notifyandroid()
{
$wxpayandroid = new \Wxpayandroid; //實(shí)例化微信支付類
$verify_result = $wxpayandroid->verifyNotify();
if ($verify_result['return_code']=='SUCCESS' && $verify_result['result_code']=='SUCCESS') {
//商戶訂單號(hào)
$out_trade_no = $verify_result['out_trade_no'];
//交易號(hào)
$trade_no = $verify_result['transaction_id'];
//交易狀態(tài)
$trade_status = $verify_result['result_code'];
//支付金額
$total_fee = $verify_result['total_fee']/100;
//支付過期時(shí)間
$pay_date = $verify_result['time_end'];
$order = new Order();
$ret = $order->getOrderN2($out_trade_no); //獲取訂單信息
$total_amount=$ret['money'];
if ($total_amount==$total_fee) {
// 驗(yàn)證成功 修改數(shù)據(jù)庫的訂單狀態(tài)等 $result['out_trade_no']為訂單號(hào)
//此處寫自己的邏輯代碼
}
exit('<xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml>');
}else{
exit('<xml><return_code><![CDATA[FAIL]]></return_code><return_msg><![CDATA[ERROR]]></return_msg></xml>');
}
}
//調(diào)用統(tǒng)一下單接口生成預(yù)支付訂單并把數(shù)據(jù)返回給APP
public function wxpayandroid(Request $request)
{
$param = $request->param(); //接收值
$tade_no = $param['orderCode'];
$order = new Order(); //實(shí)例化訂單
$ret = $order->getOrderN2($tade_no); //查詢訂單信息
$total_fee = $ret['money']; //訂單總金額
$wxpayandroid = new \Wxpayandroid; //實(shí)例化微信支付類
$res = $wxpayandroid->Weixinpayandroid($total_fee,$tade_no); //調(diào)用weixinpay方法
}
封裝一個(gè)支付類文件,并把配置參數(shù)放到支付類內(nèi),再定義控制器創(chuàng)建兩個(gè)方法,這樣兩步就可以把手機(jī)APP微信支付搞定啦。
