微信小程序支付

最近做小程序，涉及到微信支付，看了看微信小程序开发文档，尽管之前做过微信支付，还是有点懵逼，不过好在之前研究过，不然真的是无从下手。对比了一下发现，其实小程序中做支付比公众号支付要省事很多，因为不需要支付授权目录，也不需要授权域名，但是支付流程却比公众号多了一步，就是统一下单是预支付，然后需要对预支付的结果再次签名之后，才调起支付。
前期准备：
1.开通了微信支付，并且小程序绑定了微信支付；
2.准备好小程序的appid，微信支付的商户号，支付秘钥。
商户系统和微信支付系统主要交互：
1、小程序内调用登录接口，获取到用户的openid
此步骤在小程序内完成，也很简单，方法见：【小程序登录API】
2、调用商户服务器支付统一下单接口，进行预支付
/**
* 预支付请求接口(POST)
* @param string $openid openid
* @param string $body 商品简单描述
* @param string $order_sn 订单编号
* @param string $total_fee 金额
* @return json的数据
*/
public function prepay(){
$config = $this->config;
$openid = I('post.openid');
$body = I('post.body');
$order_sn = I('post.order_sn');
$total_fee = I('post.total_fee');
//统一下单参数构造
$unifiedorder = array(
'appid' => $config['appid'],
'mch_id' => $config['pay_mchid'],
'nonce_str' => self::getNonceStr(),
'body' => $body,
'out_trade_no' => $order_sn,
'total_fee' => $total_fee * 100,
'spbill_create_ip' => get_client_ip(),
'notify_url' => 'https://'.$_SERVER['HTTP_HOST'].'/Api/Wxpay/notify',
'trade_type' => 'JSAPI',
'openid' => $openid
);
$unifiedorder['sign'] = self::makeSign($unifiedorder);
//请求数据
$xmldata = self::array2xml($unifiedorder);
$url = 'https://api.mch.weixin.qq.com/pay/unifiedorder';
$res = self::curl_post_ssl($url, $xmldata);
if(!$res){
self::return_err("Can't connect the server");
}
// 这句file_put_contents是用来查看服务器返回的结果 测试完可以删除了
//file_put_contents(APP_ROOT.'/Statics/log1.txt',$res,FILE_APPEND);
$content = self::xml2array($res);
if(strval($content['result_code']) == 'FAIL'){
self::return_err(strval($content['err_code_des']));
}
if(strval($content['return_code']) == 'FAIL'){
self::return_err(strval($content['return_msg']));
}
self::return_data(array('data'=>$content));
//$this->ajaxReturn($content);
}
3、调用商户服务器再次签名接口，返回支付数据
/**
* 进行支付接口(POST)
* @param string $prepay_id 预支付ID(调用prepay()方法之后的返回数据中获取)
* @return json的数据
*/
public function pay(){
$config = $this->config;
$prepay_id = I('post.prepay_id');
$data = array(
'appId' => $config['appid'],
'timeStamp' => time(),
'nonceStr' => self::getNonceStr(),
'package' => 'prepay_id='.$prepay_id,
'signType' => 'MD5'
);
$data['paySign'] = self::makeSign($data);
$this->ajaxReturn($data);
}
4、小程序内完成支付，商户服务器接收支付回调通知，小程序加密方式一定是MD5
小程序端代码:
wx.requestPayment({
'timeStamp': '',
'nonceStr': '',
'package': '',
'signType': 'MD5',
'paySign': '',
'success':function(res){
},
'fail':function(res){
}
})
服务器回调通知:
//微信支付回调验证
public function notify(){
$xml = $GLOBALS['HTTP_RAW_POST_DATA'];
// 这句file_put_contents是用来查看服务器返回的XML数据 测试完可以删除了
//file_put_contents(APP_ROOT.'/Statics/log2.txt',$res,FILE_APPEND);
//将服务器返回的XML数据转化为数组
$data = self::xml2array($xml);
// 保存微信服务器返回的签名sign
$data_sign = $data['sign'];
// sign不参与签名算法
unset($data['sign']);
$sign = self::makeSign($data);
// 判断签名是否正确 判断支付状态
if ( ($sign===$data_sign) && ($data['return_code']=='SUCCESS') && ($data['result_code']=='SUCCESS') ) {
$result = $data;
//获取服务器返回的数据
$order_sn = $data['out_trade_no']; //订单单号
$openid = $data['openid']; //付款人openID
$total_fee = $data['total_fee']; //付款金额
$transaction_id = $data['transaction_id']; //微信支付流水号
//更新数据库
$this->updateDB($order_sn,$openid,$total_fee,$transaction_id);
}else{
$result = false;
}
// 返回状态给微信服务器
if ($result) {
$str='<xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml>';
}else{
$str='<xml><return_code><![CDATA[FAIL]]></return_code><return_msg><![CDATA[签名失败]]></return_msg></xml>';
}
echo $str;
return $result;
}
小程序端完整代码如下:
/**
* 支付函数
* @param {[type]} _payInfo [description]
* @return {[type]} [description]
*/
pay:function(_payInfo,success,fail){
var payInfo = {
body:'',
total_fee:0,
order_sn:''
}
Object.assign(payInfo, _payInfo);
if(payInfo.body.length==0){
wx.showToast({
title:'支付信息描述错误'
})
return false;
}
if(payInfo.total_fee==0){
wx.showToast({
title:'支付金额不能0'
})
return false;
}
if(payInfo.order_sn.length==0){
wx.showToast({
title:'订单号不能为空'
})
return false;
}
var This = this;
This.getOpenid(function(openid){
payInfo.openid=openid;
This.request({
url:'api/pay/prepay',
data:payInfo,
success:function(res){
var data = res.data;
console.log(data);
if(!data.status){
wx.showToast({
title:data['errmsg']
})
return false;
}
This.request({
url:'api/pay/pay',
data:{prepay_id:data.data.data.prepay_id},
success:function(_payResult){
var payResult = _payResult.data;
console.log(payResult);
wx.requestPayment({
'timeStamp': payResult.timeStamp.toString(),
'nonceStr': payResult.nonceStr,
'package': payResult.package,
'signType': payResult.signType,
'paySign': payResult.paySign,
'success': function (succ) {
success&&success(succ);
},
'fail': function (err) {
fail&&fail(err);
},
'complete': function (comp) {
}
})
}
})
}
})
})
}
