PHP JSAPI 微信支付

直接上代碼：

public static $appid = 'wxdff3ac673973bde2'; //微信對應的appid

public static $mchid = '1483472062'; // 商戶號ID 還有一個妥妥惠的商戶號，appid跟這個相同，但是mchid跟這個不同

public static $key = '934C868AC83C08913F627202AE540055'; // 微信商戶支付平臺中的 商戶支付密鑰

public static $appsecret = '3127d8774a614dd50d27050c78dfdba2'; //公眾號的appsecret 不是微信支付商戶平臺的

三 微信核心類文件 WxPayJsApiPay.php 文件中的某個類修改

//require_once dirname(dirname(__FILE__))."/WxPayApi.php";

require_once "WxPayApi.php";

/**

*

* 通過跳轉獲取用戶的openid，跳轉流程如下：

* 1、設置自己需要調回的url及其其他參數，跳轉到微信服務器https://open.weixin.qq.com/connect/oauth2/authorize

* 2、微信服務處理完成之後會跳轉回用戶redirect_uri地址，此時會帶上一些參數，如：code

*

* @return 用戶的openid

*/

public function GetOpenid()

{

//通過code獲得openid

if (!isset($_GET['code'])){

// $baseUrl = urlencode('http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].$_SERVER['QUERY_STRING';]);

$baseUrl = urlencode('http://';.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']); 後修改的這塊，之前的URL鏈接不對

$url = $this->__CreateOauthUrlForCode($baseUrl);

Header("Location: $url");

exit

} else {

//獲取code碼，以獲取openid

$code = $_GET['code'];

$openid = $this->getOpenidFromMp($code);

return $openid;

}

}

三 目錄結構

四 Controller的代碼

public function cart4(){

$save_data['coupon_id'] = I('coupon_id');

$order_id = I('order_id');

$order = M('Order')->where("order_id = $order_id")->find();

M('Order')->where("order_id = $order_id")->save($save_data);

$mods=D('OrderGoods');

$where['order_id']= I('request.order_id');

$subject_name=$mods->where($where)->select();

// 如果已經支付過的訂單直接到訂單詳情頁面. 不再進入支付頁面

if($order['pay_status'] == 1){

$order_detail_url = U("Mobile/User/order_detail",array('id'=>$order_id));

header("Location: $order_detail_url");

}

$paymentList = M('Plugin')->where("`type`='payment' and status = 1 and code in('weixin','alipay')")->select();

if(strstr($_SERVER['HTTP_USER_AGENT'],'MicroMessenger')){

$paymentList = M('Plugin')->where("`type`='payment' and status = 1 and code in('weixin','cod')")->select();

}

$paymentList = convert_arr_key($paymentList, 'code');

foreach($paymentList as $key => $val)

{

$val['config_value'] = unserialize($val['config_value']);

if($val['config_value']['is_bank'] == 2)

{

$bankCodeList[$val['code']] = unserialize($val['bank_code']);

}

}

$bank_img = include 'Application/Home/Conf/bank.php'; // 銀行對應圖片

$payment = M('Plugin')->where("`type`='payment' and status = 1")->select();

$this->assign('subject_name',$subject_name[0]['goods_name']);

$this->assign('paymentList',$paymentList);

$this->assign('bank_img',$bank_img);

$this->assign('order',$order);

$this->assign('bankCodeList',$bankCodeList);

$this->assign('pay_date',date('Y-m-d', strtotime("+1 day")));

if($this->is_weixin()){

vendor('Weixinpay.WxPayJsApiPay');

//1、獲取openid

$tools = new \\JsApiPay();

// $openId = 'orLeuv4781xUlDJjwACO1vgGjObw';

$openId = $tools->GetOpenid();

$input = new \\WxPayUnifiedOrder();

$input->SetBody($subject_name[0]['goods_name']);

$input->SetAttach("萬惠科技");

$input->SetOut_trade_no($order['order_sn']);

// $input->SetOut_trade_no('1486224422'.date("YmdHis"));

$input->SetTotal_fee($order['order_amount']*100);

$input->SetTime_start(date("YmdHis"));

$input->SetTime_expire(date("YmdHis", time() + 600));

$input->SetGoods_tag("惠生活客戶服務");

$input->SetNotify_url("http://www.wanhuikeji.cn/Api/Notify/wxPayNotify";);

$input->SetTrade_type("JSAPI");

$input->SetOpenid($openId);//$openId

// dump($input);die;

$order = \\WxPayApi::unifiedOrder($input);

// dump($order);die;

echo '

$jsApiParameters = $tools->GetJsApiParameters($order);

$this->assign('jsApiParameters',$jsApiParameters);

}

$this->display();

}
