微信app支付流程
需要的配置参数
private function wechat($body,$indent_id,$cou,$user_id,$total_fee,$ip,$domain,$nonce_str){ //微信配置信息和初始逻辑
$appid= \WxPayConfig::APPID; //appid (微信开放平台的应用appid)
$body= $body; //商品描述
$mch_id= \WxPayConfig::MCHID; //商户号(注册商户平台时,发置注册邮箱的商户id)
$notify_url= ******; //回调地址(外部可访问的)
$out_trade_no= time(); //商户订单编号自定义
$ip = $ip;
$total_fee= $total_fee; //支付金额 分
$key = \WxPayConfig::KEY;(商户平台api支付处设置的key)
$param = $this->signature($appid,$body,$mch_id,$nonce_str,$notify_url,$out_trade_no,$ip,$total_fee,$key); //请求数据转码,xml格式 下文会有介绍
$payment = Payment::create([//插入预订单(这个对应数据库字段就行,根据自己情况来)
\'indent_id\'=> $indent_id, //订单id
\'coupon_id\'=> $cou==null?0:$cou->id, //优惠券id
\'ordernum\'=> $out_trade_no,
\'user_id\'=> $user_id, //用户id
\'update_time\' => time(),
\'create_time\'=> time(),
\'way\'=> $body,
\'content\' => \'APP马上拍【微信】\'
]);
return $param;
}
2.请求数据组装成xml格式
private function signature($appid,$body,$mch_id,$nonce_str,$notify_url,$out_trade_no,$ip,$total_fee,$key){ //支付请求数据组装
$stringA = "appid=$appid&body=$body&mch_id=$mch_id&nonce_str=$nonce_str¬ify_url=$notify_url&out_trade_no=$out_trade_no&spbill_create_ip=$ip&total_fee=$total_fee&trade_type=APP";
$stringSignTemp = $stringA."&key=$key";
$sign = strtoupper(md5($stringSignTemp)); //签名
$param = "<xml>\n";
$param .= "<appid>{$appid}</appid>\n";
$param .= "<body>{$body}</body>\n";
$param .= "<mch_id>{$mch_id}</mch_id>\n";
$param .= "<nonce_str>{$nonce_str}</nonce_str>\n";
$param .= "<notify_url>{$notify_url}</notify_url>\n";
$param .= "<out_trade_no>{$out_trade_no}</out_trade_no>\n";
$param .= "<spbill_create_ip>{$ip}</spbill_create_ip>\n";
$param .= "<total_fee>{$total_fee}</total_fee>\n";
$param .= "<trade_type>APP</trade_type>\n";
$param .= "<sign>{$sign}</sign>\n";
$param .= "</xml>";
return $param;
}
3.统一下单,拿到需要的参数,并二次签名,(这一步,就可以拿到所有的字段,倒是后app请求的时候,返回给app就可以,app藉此可以调起app支付)
private function unify_curl($param,$ip,$total_fee,$domain,$body,$timestamp){//统一下单(拿到微信临时会话id,二次签名组装,返回给app ,)
$xml = $this->post_curl("https://api.mch.weixin.qq.com/pay/unifiedorder",$param); //发起请求
$info = json_decode(json_encode(simplexml_load_string($xml,\'SimpleXMLElement\',LIBXML_NOCDATA)),true); //数据结果解析
$appid= $info[\'appid\'];//二次签名
$body= $body; //商品描述
$mch_id= $info[\'mch_id\'];
$ip = $ip;
$key = \WxPayConfig::KEY;
$prepay_id= $info[\'prepay_id\'];
$noncestr = $info[\'nonce_str\'];
$SignA = strtoupper(md5("appid=$appid&noncestr=$noncestr&package=Sign=WXPay&partnerid=$mch_id&prepayid=$prepay_id×tamp=$timestamp&key=$key"));
$info[\'sign\']= $SignA;
$info[\'timestamp\'] = $timestamp;
return $info;
}
private function post_curl($url,$data,$agreement = 0){//curl远程请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
if($agreement == 0){//0 https 1 http
unset($_REQUEST[\'agreement\']);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
}
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
curl_setopt($ch, CURLOPT_USERAGENT, \'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)\');
curl_setopt($ch, CURLOPT_TIMEOUT, 15);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
4.微信支付回调
function wechat_notify(){
$postStr = @$GLOBALS["HTTP_RAW_POST_DATA"];
$getData = json_decode(json_encode(simplexml_load_string($postStr, \'SimpleXMLElement\', LIBXML_NOCDATA)),true);
if (!empty($getData[\'result_code\']) || $getData[\'result_code\'] ==\'SUCCESS\') {//如果支付成功
//你的业务逻辑
return \'SUCCESS\';
}
}
