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

namespace app\api\controller;

use app\common\model\Wxpaylog;

use xcxwxpay\database\WxPayUnifiedOrder;

use xcxwxpay\database\WxPayTransferPayment;

use xcxwxpay\WxPayApi;

public function index(){

$action = input("get.a","");

switch ($action){

case "payinfo":

$oid = input("post.oid",-1);

if(empty($oid)||$oid==""||!is_numeric($oid)||$oid==-1) $this->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");

}

// 统一下单

private function getOrderstring($body,$out_trade_no,$total_amount)

{

//统一下单

$money = $total_amount;

$money = 0.01;

$input = new WxPayUnifiedOrder();

$input->setBody($body);

$input->setAttach("");

$input->setOutTradeNo($out_trade_no);

$input->setTotalFee($money * 100);

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

$input->setTimeExpire(date("YmdHis", time() + 3*24*60*60));

$input->setNotifyUrl("https://xxxxxxx.com/api/wxapppay/notify.html");

$input->setTradeType("APP");

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

return $order;

}

public function notify()

{

$xml = file_get_contents("php://input");

$result = WxPayResults::Init($xml);

Writef("wxpaylog.txt",$xml);

if($result["result_code"]=="SUCCESS"){

$ordernumber = $result["out_trade_no"];

$paytime = formateTimeStamp(time());

$orderlogic = new orderlogic();

$orderlogic->payOrder($ordernumber,$paytime,"微支付");

$arr = array("return_code"=>"SUCCESS","return_msg"=>"OK");

echo $this->toXml($arr);

}

$this->writepaylog($result);

}

private function writepaylog($result){

$wxlog = new Wxpaylog();

$wxlog["appid"] = $result["appid"];

$wxlog["bank_type"] = $result["bank_type"];

$wxlog["cash_fee"] = $result["cash_fee"];

$wxlog["transaction_id"] = $result["transaction_id"];

$wxlog->save();

}

/**

$str = "";

for ($i = 0; $i < $length; $i++) {

$str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);

}

return $str;

}

}

1.6 前端uni-app代码如下,点击支付后执行如下代码

var uri = "Wxapppay/index.html?a=payinfo";

var param = {oid:that.orderinfo.oid};

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",

timeStamp:orderinfo.timestamp,

nonceStr:orderinfo.noncestr,

package:orderinfo.package,

signType:"MD5",

paySign:orderinfo.paySign,

orderInfo:{

appid:orderinfo.appid,

noncestr:orderinfo.noncestr,

package:"Sign=WXPay",

partnerid:orderinfo.partnerid,

prepayid:orderinfo.prepayid,

timestamp:orderinfo.timestamp,

sign:orderinfo.paySign,

},

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

namespace app\api\controller;

use app\api\common\orderlogic;

class Alipay extends Filter{

public function index(){

$action = input("get.a","");

switch ($action){

case "payinfo":

$oid = input("post.oid",-1);

if(empty($oid)||$oid==""||!is_numeric($oid)||$oid==-1) $this->apireturn(0,"invalid oid");

$result = $this->payinfo($oid);

$this->apireturn(1,"请求成功",$result);

break;

default:

$this->apireturn(0,"invalid action");

break;

}

}

private function payinfo($oid){

$orderlogic = new orderlogic();

$info = $orderlogic->getOrderInfo($oid);

Vendor('aop.AopClient');

$aop = new \AopClient();

$alipayConfig = config("alipayinfo");

$aop->gatewayUrl = $alipayConfig["gatewayUrl"];

$aop->appId = $alipayConfig["appid"];

$aop->rsaPrivateKey = $alipayConfig["privateKey"];

$aop->format = "json";

$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

$bizcontent = "{\"body\":\"$body\","

. "\"subject\": \"你的app名称-订单支付\","

. "\"out_trade_no\": \"$out_trade_no\","

. "\"timeout_express\": \"30m\","

. "\"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';

}

}

1.6 uni-app前端代码

var uri = "Alipay/index.html?a=payinfo";

var param = {oid:that.orderinfo.oid}

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:"alipay",

orderInfo:orderinfo,

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){

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{

}

}else{

}

},function(){},function(){});
