uni-app IOS app微支付、支付宝整合记录

1、微支付
准备工作
1.1 在微信开放平台（https://open.weixin.qq.com）注册并认证成为开发者账号
1.2 在移动应用内创建移动应用，审核通过后获取到该应用的AppID和AppSecret
1.3 点击微支付后面的申请进入微支付申请流程，这里分为已有微商户和没有微商户两种，没有微商户的直接申请即可；已有微商户的需要进行APPID授权（产品中心→APP支付→appid授权），进行授权以后说明这个app就可以调用app支付了;
1.4 HBuilderX manifest.json文件配置APP SDK选项勾选微信支付，填入微信开放平台获取到的appid；

1.5 准备后端代码，这里我使用的是thinkphp5.0作为后端api接口关键控制器如下

    apireturn(0,"invalid oid");
            $result = $this->payinfo($oid);
            if($result["errors"]!="") $this->apireturn(0,$result["errors"]);
            $ostring = $result["orderstring"];
            $this->apireturn(1,"请求成功",$ostring);
            break;
        default:
            $this->apireturn(0,"invalid action");
            break;
    }
}
private function payinfo($oid){
    $orderlogic = new orderlogic();
    $info = $orderlogic->getOrderInfo($oid);
    // 统一下单获取预支付订单信息
    $response = $this->getOrderstring("你app的名称-订单支付",$info["number"],$info["paymoney"]["values"]);
    // 生成调起支付请求的参数
    $input = new WxPayTransferPayment();
    $input->setPrepayId($response["prepay_id"]);

    if(!$input->isPrepayIdSet()){
        return ["errors"=>"缺少调起支付必填参数prepayid"];
    }
    $input->setAppid(WxPayConfig::$APPID);
    $input->setPartnerId(WxPayConfig::$MCHID);
    $input->setPackage("Sign=WXPay");
    $input->setNonceStr(self::getNonceStr());//随机字符串
    $input->setTimeStamt(time());

    $arr = array(
        "appid" => $input->getAppid(),
        "partnerid"=>$input->getPartnerId(),
        "prepayid"=>$input->getPrepayId(),
        "package"=>"Sign=WXPay",
        "noncestr"=>$input->getNonceStr(),

1.6 前端uni-app代码如下,点击支付后执行如下代码

                that.$post(uri,param,"POST",function(res){
                    var jsondata = res.data;
                    //console.log(JSON.stringify(jsondata));
                    if(jsondata.code==1){
                        var orderinfo = jsondata.data;
                        if(orderinfo){
                            uni.requestPayment({
                                provider:"wxpay",

                                orderInfo:{
                                    appid:orderinfo.appid,

                                success:function(res){
                                    uni.showToast({
                                        title:"支付成功",
                                        icon:"success",
                                        duration:2000,
                                        complete:function(){
                                            uni.reLaunch({
                                                url:"showresult?paytype=1"
                                            });
                                        }
                                    });
                                },
                                fail:function(res){
                                    // console.log(JSON.stringify(res));
                                    uni.showToast({
                                        title: '支付失败，请到订单中心重新支付',
                                        icon: "none",
                                        duration: 2000,
                                        complete: function () {
                                            wx.reLaunch({
                                                url: 'showresult?paytype=3',
                                            });
                                        }
                                    });
                                }
                            });
                        }
                    }else{
                        
                    }
                },function(){},function(){});

注意注意注意：如果是默认基座的话会提示：HBuilder mainifest.json中配置的支付appid和生成订单使用的appid不一致,如果是HB调试请在线打包,http://ask.dcloud.net.cn/article/282"，必须使用自定义基座才能真机调试支付

2、支付宝支付
准备工作
1.1 在支付宝平台注册商户用户
1.2 在支付宝商户后台产品中心签约app支付
1.3 在蚂蚁金服开放平台（https://open.alipay.com）开发中心→网页和移动应用新增app应用，通过以后设置好应用公钥，系统会自动生成支付宝公钥注意新增的时候 iOS bundle ID一定要填写正确
1.4 HBuilder mainifest.json中设置支付宝ios scheme用于支付完成跳转回应用。
1.5 后台代码参考支付宝示例代码

apireturn(0,"invalid oid");
            $result = $this->payinfo($oid);

            $this->apireturn(1,"请求成功",$result);

        default:

            break;
    }
}

private function payinfo($oid){
    $orderlogic = new orderlogic();
    $info = $orderlogic->getOrderInfo($oid);
    Vendor('aop.AopClient');
    $aop = new \AopClient();
    $alipayConfig = config("alipayinfo");

    $aop->charset       = "utf-8";
    $aop->signType      = "RSA2";
    $aop->alipayrsaPublicKey = $alipayConfig["publicKey"];
    Vendor("aop.request.AlipayTradeAppPayRequest");
    $request = new \AlipayTradeAppPayRequest();

    $request->setNotifyUrl($alipayConfig["notifyUrl"]);

    $body = "你的app名称订单支付";
    $out_trade_no = $info["number"];
    $total_amount = formatMoney($info["paymoney"]["values"]);
    $total_amount = 0.01;// 实际上线后注释掉

        . "\"total_amount\": \"$total_amount\","
        . "\"product_code\":\"QUICK_MSECURITY_PAY\""
        . "}";
    $request->setBizContent($bizcontent);
    $response = $aop->sdkExecute($request);

    return $response;
}
public function notify()
{
    $data = input("post.");

    $str = ToUrlParams($data);
    Vendor('aop.AopClient');
    $aop = new \AopClient();
    $alipayConfig = config("alipayinfo");
    $aop->alipayrsaPublicKey = $alipayConfig["publicKey"];
    $flag = $aop->rsaCheckV1(input("post."), NULL, "RSA2");

    if($flag){
        // 消息验证通过,更改订单状态
        $states = input("post.trade_status");

        if($states == "TRADE_SUCCESS"){
            $ordernumber = input("post.out_trade_no");
            $paytime = input("post.gmt_payment");
            $orderlogic = new orderlogic();
            $orderlogic->payOrder($ordernumber,$paytime,"支付宝");
        }
        echo "success";
    }
    echo 'filed';
}
}
