HBuilder基礎上APP呼叫支付寶、微信支付（PHP）
阿新 • • 發佈：2018-11-13
支付寶後端程式碼：
/** * @param Request $request * @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View * 訂單頁面支付（支付寶支付） */ public function pay(Request $request){ $callback = $request->get('callback'); $pri_key = '私鑰'; $arr = [ 'app_id' => '自己的APPID', 'method' => 'alipay.trade.app.pay', 'charset' => 'utf-8', 'sign_type' => 'RSA2', 'timestamp' => date('Y-m-d H:i:s'), 'version' => '1.0', 'notify_url' => '自己的回撥地址', 'biz_content' => '', ]; $arr_param = [ 'subject' => '測試', 'out_trade_no' => $order_number, 'total_amount' =>strval($sum_price), 'product_code' => 'QUICK_MSECURITY_PAY', ]; $arr['biz_content'] = json_encode($arr_param,JSON_UNESCAPED_UNICODE); ksort($arr); $str = urldecode(http_build_query($arr)); $rsa = new \RSA(); $arr['sign'] = $rsa->rsaSign($str, $pri_key); $content = json_encode(['error_code'=>0,'content'=>http_build_query($arr)]); return $callback."(".$content.")"; }
支付寶非同步回撥程式碼：
/** * 支付寶非同步 */ public function notify(Request $request){ $pub_key = '自己的公鑰'; //獲取支付寶傳送的資料 $params = $request -> all(); //file_put_contents('./test.php', print_r($params,true) . "\r\n",FILE_APPEND); $sign = $params['sign']; //除去sign、sign_type unset($params['sign']); unset($params['sign_type']); //排序 ksort($params); //拼接字串 $str = urldecode(http_build_query($params)); //使用公鑰驗籤 $rsa = new \RSA(); $stat = $rsa->rsaCheck($str, $pub_key, $sign); if($stat){ //判斷支付狀態 //file_put_contents('test.php',$params,FILE_APPEND); if($params['trade_status'] == 'TRADE_SUCCESS' || $params['trade_status'] == 'TRADE_FINISHED'){ $data = DB::table('order')->where('order_number',$params['out_trade_no'])->first(); //根據訂單號 判斷訂單金額是否一致 if($data->sum_price == $params['total_amount']){ //update order stat 更新訂單狀態 $res = DB::table('order')->where('order_number',$params['out_trade_no'])->where('status',1)->update(['status'=>2]); if($res > 0){ echo 'success'; } } } } }
支付寶前段程式碼：
function plusReady(){ // 獲取支付通道 plus.payment.getChannels(function(channels){ channel=channels[0]; },function(e){ alert("獲取支付通道失敗："+e.message); }); } document.addEventListener('plusready',plusReady,false); $('#zhifu').click(function(){ var order_num = sessionStorage.getItem('order_num'); var sum_price = sessionStorage.getItem('sum_price'); var token = localStorage.getItem('token'); $.ajax({ method: "get", url: "http://lmy.jinxiaofei.xyz/pay", data: {token:token,order_number:order_num,sum_price:sum_price}, dataType:'jsonp' }).done(function( msg ) { if(msg.error_code == 0){ plus.payment.request(channel,msg.content,function(result){ plus.nativeUI.alert("支付成功！",function(){ location.href = './index.html'; }); },function(error){ plus.nativeUI.alert("支付失敗：" + error.code); }); }else{ layerUtil.tip(msg.content); } }) })
微信支付後端：
/**
* 微信支付
*/
public function weixin(Request $request){
$callback = $request->get('callback');
$key = 'K8djgYUIQDMCXdr0855kgjdjDGUJDDoi';
$param = [
'appid' => 'wx372200381123eeb2',
'mch_id' => '1517545941',
'nonce_str' => uniqid(),
'body' => 'APP支付測試',
'out_trade_no' => time().rand(1000,9999),
'total_fee' => 1,
'spbill_create_ip' => $_SERVER['REMOTE_ADDR'],
'notify_url' => 'http://lmy.jinxiaofei.xyz/wx_notify',
'trade_type' => 'APP',
];
$sign = $this -> get_sign($param);
$param['sign'] = $sign;
$url = 'https://api.mch.weixin.qq.com/pay/unifiedorder';
$xml = $this -> ArrToXml($param);
$data_xml = $this -> postStr($url,$xml);
$data = $this -> XmlToArr($data_xml);
$arr = [
'appid' => 'wx372200381123eeb2',
'partnerid' => '1517545941',
'prepayid' => $data['prepay_id'],
'package' => 'Sign=WXPay',
'noncestr' => uniqid(),
'timestamp' => time(),
];
$sign2 = $this -> get_sign($arr);
$arr['sign'] = $sign2;
return $callback."({content:".json_encode($arr)."})";
}
public function get_sign($arr){
$key = 'K8djgYUIQDMCXdr0855kgjdjDGUJDDoi';
ksort($arr);
$str = urldecode(http_build_query($arr)).'&key='.$key;
$sign = strtoupper(md5($str));
return $sign;
}
/**
* 微信非同步
*/
public function wx_notify(){
}
//Xml 檔案轉陣列
public function XmlToArr($xml)
{
if($xml == '') return '';
libxml_disable_entity_loader(true);
$arr = json_decode(json_encode(simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA)), true);
return $arr;
}
//陣列轉XML
public function ArrToXml($arr)
{
if(!is_array($arr) || count($arr) == 0) return '';
$xml = "<xml>";
foreach ($arr as $key=>$val)
{
if (is_numeric($val)){
$xml.="<".$key.">".$val."</".$key.">";
}else{
$xml.="<".$key."><![CDATA[".$val."]]></".$key.">";
}
}
$xml.="</xml>";
return $xml;
}
//post 字串到介面
public function postStr($url,$postfields){
$ch = curl_init();
$params[CURLOPT_URL] = $url; //請求url地址
$params[CURLOPT_HEADER] = false; //是否返回響應頭資訊
$params[CURLOPT_RETURNTRANSFER] = true; //是否將結果返回
$params[CURLOPT_FOLLOWLOCATION] = true; //是否重定向
$params[CURLOPT_POST] = true;
$params[CURLOPT_SSL_VERIFYPEER] = false;//禁用證書校驗
$params[CURLOPT_SSL_VERIFYHOST] = false;
$params[CURLOPT_POSTFIELDS] = $postfields;
curl_setopt_array($ch, $params); //傳入curl引數
$content = curl_exec($ch); //執行
curl_close($ch); //關閉連線
return $content;
}微信支付前段：
function plusReady(){
// 獲取支付通道
plus.payment.getChannels(function(channels){
channel=channels[1];
},function(e){
alert("獲取支付通道失敗："+e.message);
});
}
document.addEventListener('plusready',plusReady,false);
$('#zhifu').click(function(){
$.ajax({
method: "get",
url: "http://lmy.jinxiaofei.xyz/weixin",
data: {},
dataType:'jsonp'
}).done(function( msg ) {
plus.payment.request(channel,msg.content,function(result){
plus.nativeUI.alert("支付成功！",function(){
location.href = './index.html';
});
},function(error){
plus.nativeUI.alert("支付失敗：" + error.code);
});
})
})注意：不管支付寶支付還是微信支付都需要在HBuilder中的配置檔案（manifest.json）的SDK配置中開通支付寶、微信支付
RSA類就是生成、驗證簽名的方法，就不完全上傳了，可以自己根據官方文件生成、驗證（並不複雜），最後預祝大家除錯成功
