序言


随着微信被越来越多的人使用,微信商城成为如今的热门。每一个商城都需要有自己的支付方式,微信商城也不例外。微信公众号支付就是微信商城的一种支付方式,微信支付随着微信的推广使用也被广泛应用。今天我主要讲的是yii2嵌入微信公众号支付,微信官网的微信支付文档比较简洁,接下来跟着我来看一下yii2如何嵌入微信公众号支付,以及需要注意的事项吧。


前期准备工作


首先必须有一个微信公众号,并且需要在微信公众平台申请微信支付。微信公众平台的地址是:https://mp.weixin.qq.com/cgi-bin/loginpage。申请的过程我这边就不写了,录公众平台以后就可以看到。
其次需要先配置一个域名,必须是80端口,然后在申请完微信支付以后配置上支付授权目录。
准备工作完成以后我们可以开始开发了。


代码分析


1、我们需要获取到关注微信公众号的人的openid。获取openid,我这边是通过网页授权获取用户基本信息接口获取的。其实在github上已经有封装好的关于微信的开发的接口,我们可以直接从上面下载,以后基于yii2的开发微信的其他的功能可以使用。网址是:https://github.com/callmez/yii2-wechat-sdk大家可以下载然后安装。我的openid的获取也是在此基础上更改的。安装完成以后的目录结构如下图:


我这边使用的是MpWechat.php,在MpWechat.php中我增加了一个方法获取openid。


public function getOpenid($turl)
{
if (!isset($_GET['code'])){
//触发微信返回code码
$url=$this->getOauth2AuthorizeUrl($turl, $this->state, 'snsapi_userinfo');
Header("Location: $url");
exit();
} else {
//获取code码,以获取openid
$code = $_GET['code'];
$access_info = $this->getOauth2AccessToken($code);
return $access_info;
}
}

$turl是获取到code以后需要跳转的地址。
在控制其中获取openid我是这样写的:


public function actionView($id)
{
$openid=isset($_COOKIE['openid'])?$_COOKIE['openid']:'';
if(empty($openid))
{
$t_url=Url::to([[email protected]/clue/view?id='.$id],true);//这个是获取到code以后需要跳转的url。Url这个是在头部需要增加:use yiihelpersUrl
$info=$this->wechat->getOpenid($t_url);//注:$this->wechat安装完成yii2-wechat-sdk以后配置以后可以使用
if($info){
setcookie('access_token',$info['access_token'],time()+86400*365);
setcookie('openid',$info['openid'],time()+86400*365);
}
}
}
将获取到的openid放入的cookie中储存。

2、openid获取以后可以进行开发微信支付,我这边将微信支付封装成了一个类,可以配置访问。


第一步、我们可以在common/config/main.php中配置


return [
'vendorPath' => dirname(dirname(__DIR__)) . '/vendor',
'language' => 'zh-CN', // 启用国际化支持
'sourceLanguage' => 'zh-CN', // 源代码采用中文
'timeZone' => 'Asia/Shanghai', // 设置时区
'components' => [
'cache' => [
'class' => 'yiicachingFileCache',
],
'user' => [
'identityClass' => 'loginmodelsUser',
'enableAutoLogin' => false, //开启authTimeout失效
'identityCookie' => ['name' => '_identity', 'httpOnly' => true,'domain' => '.' . DOMAIN],
// 'returnUrl'=>'//' . DOMAIN_HOME,
'authTimeout' => 24*3600*30, // 30 days
],
'session' => [
'timeout' => 24*3600*30, // 30 days
'useCookies' => true,
'cookieParams' => [
'domain' => '.' . DOMAIN,
'lifetime' => 24*3600*30,
],
],
//这个是支付的
'payment' => [
'class'=>'commonwidgetspaymentInstance',
'weixinjspi_config' => [
'code' => 2,
'appid' => 'wx88ee3ca8c06be5c6',//微信的appid
'secret' => '48180f87c2693d50b29d822d019999',//appsecret,在申请完公众号以后可以看到
'mch_id' => '13260614455',//商户号
'key' => '16ceshi',//key需要设置
'cert_path' => '',//可以不用填写
'key_path' => '',//可以不用填写
],
],
],

我上面的appid、key等都是错误信息需要你们根据自己申请的微信支付进行填写
第二步、在commonwidgets中加入payment文件夹,在文件夹中增加Instance.php


<?php
namespace commonwidgetspayment;
use yiibaseComponent;
class Instance extends Component{
private $weixin_config;
private $weixins_config;
private $weixinjspi_config;
private $alipay_config;
private $balance_config;
private $_weixin = null;
private $_weixins = null;
private $_alipay = null;
private $_balance = null;
private $_weixinjspi = null;
public function setWeixin_config($config)
{
$this->weixin_config = $config;
}
public function setWeixins_config($config)
{
$this->weixins_config = $config;
}
public function setWeixinjspi_config($config)
{
$this->weixinjspi_config = $config;
}
public function setAlipay_config($config)
{
$this->alipay_config = $config;
}
public function setBalance_config($config)
{
$this->balance_config = $config;
}
/**
* 组合使用余额支付和其他支付
* @param $order
* @param $payment
* @param $balance
*/
public function unionPay($order,$payment,$balance,$notify)
{
$res = [];
$total_fee = $order['total_fee'];
if($balance > 0)
{
$pay = $this->getBalance();
if($balance >= $total_fee)
{
$res['balance'] = $pay->pay($order);
return $res;
}
else
{
$order['total_fee'] = $balance;
$res['balance'] = $pay->pay($order);
$total_fee -= $balance;
}
}
$order['total_fee'] = $total_fee;
$pay = $this->$payment;
$pay->setNotifyUrl($notify);
$res[$payment] = $pay->prepay($order);
//$res[$payment]['balance'] = $balance;
return $res;
}
/**
* 获得支付宝支付
* @param null $notify_url
* @return mixed|object
*/
public function getAlipay($notify_url = null)
{
$this->alipay_config = array_merge(['class'=>Alipay::className()],$this->alipay_config);
//'var_dump($this->alipay_config);exit;
return $this->_getPayment('_alipay',$notify_url);
}
/**
* 获得微信app c端支付
* @param null $notify_url
* @return mixed|object
*/
public function getWeixin($notify_url = null)
{
$this->weixin_config = array_merge(['class'=>Weixin::className()],$this->weixin_config);
return $this->_getPayment('_weixin',$notify_url);
}
/**
* 获得手机微信端支付
* @param null $notify_url
* @return mixed|object
*/
public function getWeixinjspi($notify_url = null)
{
$this->weixinjspi_config = array_merge(['class'=>Weixinjspi::className()],$this->weixinjspi_config);
return $this->_getPayment('_weixinjspi',$notify_url);
}
/**
* 获得微信app s端支付
* @param null $notify_url
* @return mixed|object
*/
public function getWeixins($notify_url = null)
{
$this->weixins_config = array_merge(['class'=>Weixin::className()],$this->weixins_config);
return $this->_getPayment('_weixins',$notify_url);
}
/**
* 获得余额支付
* @return mixed|object
*/
public function getBalance()
{
$this->balance_config = array_merge(['class'=>Balance::className()],$this->balance_config);
return $this->_getPayment('_balance',null);
}
/**
* @param $name
* @param $notify_url
* @return mixed|object
* @throws yiibaseInvalidConfigException
*/
private function _getPayment($name, $notify_url)
{
$config = substr($name.'_config',1);
if(is_null($this->{$name}))
{
$this->{$name} = Yii::createObject($this->{$config});
}
if(!is_null($notify_url))
{
$this->{$name}->setNotifyUrl($notify_url);
}
return $this->{$name};
}
}

这个类其实是结合了其他的支付方式,其中现在最主要的是getWeixinjspi($notify_url = null)这个方法。
除了这个还需要增加Weixinjspi.php

if($useCert == true && !empty($this->cert_path) && !empty($this->key_path)){
//设置证书
//使用证书:cert 与 key 分别属于两个.pem文件
curl_setopt($ch,CURLOPT_SSLCERTTYPE,'PEM');
curl_setopt($ch,CURLOPT_SSLCERT, $this->cert_path);
curl_setopt($ch,CURLOPT_SSLKEYTYPE,'PEM');
curl_setopt($ch,CURLOPT_SSLKEY, $this->key_path);
}
//post提交方式
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
//运行curl
$data = curl_exec($ch);
//返回结果
if($data){
curl_close($ch);
return $data;
} else {
$error = curl_errno($ch);
curl_close($ch);
throw new InvalidValueException("curl出错,错误码:{$error}");
}
}
}

还需要增加一个Notifyurl.php


<?php
namespace commonwidgetspayment;
use Yii;
use commonwidgetspaymentWeixinjspi;
class Notifyurl
{
public function notify($code)
{
$funame='get'.$code;
$respmodel=Yii::$app->payment->$funame();
$result=$respmodel->notify();
if($result){
//商户订单号
$out_trade_no = $result['out_trade_no'];
//交易号
$trade_no = $result['trade_no'];
//交易状态
$trade_status = $result['trade_status']; if ($trade_status == 'TRADE_SUCCESS')
{
$this->update_status($out_trade_no,$trade_no,1);
echo"success";
}else{
echo"fail";
}
}else{
echo"fail";
}}
//支付状态更改
public function update_status($out_trade_no,$trade_no,$pay_status)
{
}
}
?>

第三步、我们如何使用呢,
在我们需支付的controller中,
//微信支付


public function actionWeixinpay()
{
$openid=isset($_COOKIE['openid'])?$_COOKIE['openid']:'';if($openid)
{
$order_=[
'goods_desc'=>'测试',
'order_sn' =>'2222',
'total_fee' =>12,
'body'=>'测试',
'time_start' =>date("YmdHis"),
'time_expire'=>date("YmdHis", time() + 86400*300),
'goods_tag' =>'',
'notify_url'=>Url::to([[email protected]/respond/updatepay'],true),//这是回调地址,微信通知的地址
'openid'=>$openid,];
$paymodel=Yii::$app->payment->getWeixinjspi();
$result=$paymodel->pay($order_);//生成预付单
if($result)
{
$jsstr=$paymodel->getJs($result,$order_['order_sn']);
//根据预付单信息生成js,详细的可以看上面的类的方法。
}}
echo $jsstr;}

第四步、在view层我们可以这样写:
