yii2嵌入微信公衆號支付
序言javascript
隨着微信被愈來愈多的人使用，微信商城成爲現在的熱門。每個商城都須要有本身的支付方式，微信商城也不例外。微信公衆號支付就是微信商城的一種支付方式，微信支付隨着微信的推廣使用也被普遍應用。今天我主要講的是yii2嵌入微信公衆號支付，微信官網的微信支付文檔比較簡潔，接下來跟着我來看一下yii2如何嵌入微信公衆號支付，以及須要注意的事項吧！php
前期準備工做html
首先必須有一個微信公衆號，而且須要在微信公衆平臺申請微信支付。微信公衆平臺的地址是：https://mp.weixin.qq.com/cgi-bin/loginpage。申請的過程我這邊就不寫了，錄公衆平臺之後就能夠看到。
其次須要先配置一個域名，必須是80端口,而後在申請完微信支付之後配置上支付受權目錄。
準備工做完成之後咱們能夠開始開發了。java
代碼分析git
一、咱們須要獲取到關注微信公衆號的人的openid。獲取openid,我這邊是經過網頁受權獲取用戶基本信息接口獲取的。其實在github上已經有封裝好的關於微信的開發的接口，咱們能夠直接從上面下載，之後基於yii2的開發微信的其餘的功能能夠使用。網址是：https://github.com/callmez/yii2-wechat-sdk 你們能夠下載而後安裝。個人openid的獲取也是在此基礎上更改的。安裝完成之後的目錄結構以下圖：
github
我這邊使用的是MpWechat.php,在MpWechat.php中我增長了一個方法獲取openid。web
public function getOpenid($turl)
{
if (!isset($_GET['code'])){
//觸發微信返回code碼
$url=$this->getOauth2AuthorizeUrl($turl, $this->state, 'snsapi_userinfo');
Header("Location: $url");
exit();
} else {
//獲取code碼，以獲取openid
$code = $_GET['code'];
$access_info = $this->getOauth2AccessToken($code);
return $access_info;
}
}
$turl是獲取到code之後須要跳轉的地址。
在控制其中獲取openid我是這樣寫的：ajax
public function actionView($id)
{
$openid=isset($_COOKIE['openid'])?$_COOKIE['openid']:'';
if(empty($openid))
{
$t_url=Url::to(['@web/clue/view?id='.$id],true);//這個是獲取到code之後須要跳轉的url。Url這個是在頭部須要增長：use yii\helpers\Url
$info=$this->wechat->getOpenid($t_url);//注:$this->wechat安裝完成yii2-wechat-sdk之後配置之後能夠使用
if($info){
setcookie('access_token',$info['access_token'],time()+86400*365);
setcookie('openid',$info['openid'],time()+86400*365);
}
}
}
將獲取到的openid放入的cookie中儲存。
二、openid獲取之後能夠進行開發微信支付，我這邊將微信支付封裝成了一個類，能夠配置訪問。json
第一步、咱們能夠在common/config/main.php中配置api
return [
'vendorPath' => dirname(dirname(__DIR__)) . '/vendor',
'language' => 'zh-CN', // 啓用國際化支持
'sourceLanguage' => 'zh-CN', // 源代碼採用中文
'timeZone' => 'Asia/Shanghai', // 設置時區
'components' => [
'cache' => [
'class' => 'yii\caching\FileCache',
],
'user' => [
'identityClass' => 'login\models\User',
'enableAutoLogin' => false, //開啓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,
],
],
//這個是支付的
'payment' => [
'class'=>'common\widgets\payment\Instance',
'weixinjspi_config' => [
'code' => 2,
'appid' => 'wx88ee3ca8c06be5c6',//微信的appid
'secret' => '48180f87c2693d50b29d822d019999',//appsecret，在申請完公衆號之後能夠看到
'mch_id' => '13260614455',//商戶號
'key' => '16ceshi',//key須要設置
'cert_path' => '',//能夠不用填寫
'key_path' => '',//能夠不用填寫
],
],
],
我上面的appid、key等都是錯誤信息須要大家根據本身申請的微信支付進行填寫
第二步、在commonwidgets中加入payment文件夾，在文件夾中增長Instance.php
<?php
namespace common\widgets\payment;
use yii\base\Component;
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;
}
/**
* 組合使用餘額支付和其餘支付
* @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;
}
/**
* 得到支付寶支付
* @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);
}
/**
* 得到微信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);
}
/**
* 得到手機微信端支付
* @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);
}
/**
* 得到微信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);
}
/**
* 得到餘額支付
* @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 $notify_url
* @return mixed|object
* @throws \yii\base\InvalidConfigException
*/
private function _getPayment($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};
}
}
這個類實際上是結合了其餘的支付方式，其中如今最主要的是getWeixinjspi($notify_url = null)這個方法。
除了這個還須要增長Weixinjspi.php
<?php

$order['mch_id'] = $this->mch_id;
$order['nonce_str'] = $this->randomStr();
$order['sign'] = $this->sign($order);
$xml = $this->toXml($order);
$response = $this->postXmlCurl($xml, $this->search_refund_url, true, $timeOut);
$result = $this->convertResponse($response);
return $result;
}
private function postXmlCurl($xml, $url, $useCert = false, $second = 30)
{
$ch = curl_init();
//設置超時
curl_setopt($ch, CURLOPT_TIMEOUT, $second);
//若是有配置代理這裏就設置代理
if($this->curl_proxy_host != "0.0.0.0" && $this->curl_proxy_port != 0){
curl_setopt($ch,CURLOPT_PROXY, $this->curl_proxy_host);
curl_setopt($ch,CURLOPT_PROXYPORT, $this->curl_proxy_port);
}
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,FALSE);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,FALSE);
//設置header
curl_setopt($ch, CURLOPT_HEADER, FALSE);
//要求結果爲字符串且輸出到屏幕上
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
if($useCert == true && !empty($this->cert_path) && !empty($this->key_path)){
//設置證書
//使用證書：cert 與 key 分別屬於兩個.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);
//運行curl
$data = curl_exec($ch);
//返回結果
if($data){
curl_close($ch);
return $data;
} else {
$error = curl_errno($ch);
curl_close($ch);
throw new InvalidValueException("curl出錯，錯誤碼:{$error}");
}
}
}
還須要增長一個Notifyurl.php
<?php
namespace common\widgets\payment;
use Yii;
use common\widgets\payment\Weixinjspi;
class Notifyurl
{
public function notify($code)
{
$funame='get'.$code;
$respmodel=Yii::$app->payment->$funame();
$result=$respmodel->notify();
if($result){
//商戶訂單號
$out_trade_no = $result['out_trade_no'];
//交易號
$trade_no = $result['trade_no'];
//交易狀態
$trade_status = $result['trade_status'];
if ($trade_status == 'TRADE_SUCCESS')
{
$this->update_status($out_trade_no,$trade_no,1);
echo "success";
}else{
echo "fail";
}
}else{
echo "fail";
}
}
//支付狀態更改
public function update_status($out_trade_no,$trade_no,$pay_status)
{
}
}
?>
第三步、咱們如何使用呢，
在咱們需支付的controller中，
//微信支付
public function actionWeixinpay()
{
$openid=isset($_COOKIE['openid'])?$_COOKIE['openid']:'';
if($openid)
{
$order_=[
'goods_desc'=>'測試',
'order_sn' =>'2222',
'total_fee' =>12,
'body'=>'測試',
'time_start' =>date("YmdHis"),
'time_expire'=>date("YmdHis", time() + 86400*300),
'goods_tag' =>'',
'notify_url'=>Url::to(['@web/respond/updatepay'],true),//這是回調地址，微信通知的地址
'openid'=>$openid,
];
$paymodel=Yii::$app->payment->getWeixinjspi();
$result=$paymodel->pay($order_);//生成預付單
if($result)
{
$jsstr=$paymodel->getJs($result,$order_['order_sn']);
//根據預付單信息生成js，詳細的能夠看上面的類的方法。
}
}
echo $jsstr;
}
第四步、在view層咱們能夠這樣寫：
<button type="button" class="btn red-sunglo" onclick="pay_(2)" >
<div id="js_">
</div>
<script>
//支付
function pay_(id)
{
$.ajax({
type:"get",
url:"/ceshi/weixinpay?id="+id,//這是訪問的地址
datatype:"json",
data:{},
success: function(data)
{
if(data!='')
{
$("#js_").html(data);
callpay();
}
//alert(data);
}
})
}
</script>
我這邊是採用的ajax的形式進行支付的，能夠根據本身的狀況進行調整
第五步、支付最重要的是須要回調,yii2增長了Csrf驗證，禁止了外部的訪問，咱們在控制其中寫回調方法的時候必須增長：
public function beforeAction($action) {
$this->enableCsrfValidation = false;
return parent::beforeAction($action);
}
否則微信將訪問不到。
回調的方法使用：
use common\widgets\payment\Weixinjspi;
use common\widgets\payment\Notifyurl;
public function actionUpdatepay()
{
$model=new Notifyurl();
$model->notify('Weixinjspi');
}
以上就是個人微信支付。第一次寫文章，有不完善的地方請多包涵，有不對的地方請指出我這邊再完善
