HBuilder基础上APP调用支付宝、微信支付（PHP）
支付宝后端代码：
/**
* @param Request $request
* @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
* 订单页面支付（支付宝支付）
*/
public function pay(Request $request){
$callback = $request->get('callback');
$pri_key = '私钥';
$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' => '自己的回调地址',
'biz_content' => '',
];
$arr_param = [
'subject' => '测试',
'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.")";
}支付宝异步回调代码：
/**
* 支付宝异步
*/
public function notify(Request $request){
$pub_key = '自己的公钥';
//获取支付宝发送的数据
$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);
//拼接字符串
$str = urldecode(http_build_query($params));
//使用公钥验签
$rsa = new \RSA();
$stat = $rsa->rsaCheck($str, $pub_key, $sign);
if($stat){
//判断支付状态
//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();
//根据订单号 判断订单金额是否一致
if($data->sum_price == $params['total_amount']){
//update order stat 更新订单状态
$res = DB::table('order')->where('order_number',$params['out_trade_no'])->where('status',1)->update(['status'=>2]);
if($res > 0){
echo 'success';
}
}
}
}
}支付宝前段代码：
function plusReady(){
// 获取支付通道
plus.payment.getChannels(function(channels){
channel=channels[0];
},function(e){
alert("获取支付通道失败："+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("支付失败：" + error.code);
});
}else{
layerUtil.tip(msg.content);
}
})

});
}
document.addEventListener('plusready',plusReady,false);

plus.nativeUI.alert("支付成功！",function(){
location.href = './index.html';
});
},function(error){
plus.nativeUI.alert("支付失败：" + error.code);
});
})
})注意：不管支付宝支付还是微信支付都需要在HBuilder中的配置文件（manifest.json）的SDK配置中开通支付宝、微信支付
RSA类就是生成、验证签名的方法，就不完全上传了，可以自己根据官方文档生成、验证（并不复杂），最后预祝大家调试成功
