微信支付已經(jīng)普及到很多地方了,今天就整理了一下微信小程序支付的前后端代碼,方便以后直接拿過來使用,微信小程序可以直接調(diào)起微信支付,只需要后臺(tái)配置好所有參數(shù)就可以支付成功非常方便,這里就直接將所有代碼貼上不做過多解釋了。
前端代碼:
wx.request({ url: 'https://www.yourhost.com/weixin/WeiActivity/payJoinfee',//改成你自己的鏈接 header: { 'Content-Type': 'application/x-www-form-urlencoded' }, method:'POST', success: function(res) { console.log(res.data); console.log('調(diào)起支付'); wx.requestPayment({ 'timeStamp': res.data.timeStamp, 'nonceStr': res.data.nonceStr, 'package': res.data.package, 'signType': 'MD5', 'paySign': res.data.paySign, 'success':function(res){ console.log('success'); wx.showToast({ title: '支付成功', icon: 'success', duration: 3000 }); }, 'fail':function(res){ console.log('fail'); }, 'complete':function(res){ console.log('complete'); } }); }, fail:function(res){ console.log(res.data) } });
后端代碼:
//支付費(fèi)用 public function payJoinfee(){ $appid='wx888888888'; $openid='oCQwY0Q_pzrQpu8888888'; $mch_id='141388888'; $key='9A0A86888888888'; import('Weixin.Lib.WeixinPay'); $weixinpay = new \WeixinPay($appid,$openid,$mch_id,$key); $return=$weixinpay->pay(); $this->response($return,'json'); }

appid=$appid; $this->openid=$openid; $this->mch_id=$mch_id; $this->key=$key; } public function pay(){ //統(tǒng)一下單接口 $return=$this->weixinapp(); return $return; } //統(tǒng)一下單接口 private function unifiedorder(){ $url='https://api.mch.weixin.qq.com/pay/unifiedorder'; $parameters=array( 'appid'=>$this->appid,//小程序ID 'mch_id'=>$this->mch_id,//商戶號(hào) 'nonce_str'=>$this->createNoncestr(),//隨機(jī)字符串 'body'=>'測試',//商品描述 'out_trade_no'=>'2015450806125346',//商戶訂單號(hào) 'total_fee'=>floatval(0.01*100),//總金額 單位 分 'spbill_create_ip'=>$_SERVER['REMOTE_ADDR'],//終端IP 'notify_url'=>'http://www.weixin.qq.com/wxpay/pay.php',//通知地址 'openid'=>$this->openid,//用戶id 'trade_type'=>'JSAPI'//交易類型 ); //統(tǒng)一下單簽名 $parameters['sign']=$this->getSign($parameters); $xmlData=arrayToXml($parameters); $return=xmlToArray(postXmlSSLCurl($xmlData,$url,60)); return $return; } //微信小程序接口 private function weixinapp(){ //統(tǒng)一下單接口 $unifiedorder=$this->unifiedorder(); $parameters=array( 'appId'=>$this->appid,//小程序ID 'timeStamp'=>''.time().'',//時(shí)間戳 'nonceStr'=>$this->createNoncestr(),//隨機(jī)串 'package'=>'prepay_id='.$unifiedorder['prepay_id'],//數(shù)據(jù)包 'signType'=>'MD5'//簽名方式 ); //簽名 $parameters['paySign']=$this->getSign($parameters); return $parameters; } //作用:產(chǎn)生隨機(jī)字符串,不長于32位 private function createNoncestr($length = 32 ){ $chars = "abcdefghijklmnopqrstuvwxyz0123456789"; $str =""; for ( $i = 0; $i < $length; $i++ ) { $str.= substr($chars, mt_rand(0, strlen($chars)-1), 1); } return $str; } //作用:生成簽名 private function getSign($Obj){ foreach ($Obj as $k => $v){ $Parameters[$k] = $v; } //簽名步驟一:按字典序排序參數(shù) ksort($Parameters); $String = $this->formatBizQueryParaMap($Parameters, false); //簽名步驟二:在string后加入KEY $String = $String."&key=".$this->key; //簽名步驟三:MD5加密 $String = md5($String); //簽名步驟四:所有字符轉(zhuǎn)為大寫 $result_ = strtoupper($String); return $result_; } ///作用:格式化參數(shù),簽名過程需要使用 private function formatBizQueryParaMap($paraMap, $urlencode){ $buff = ""; ksort($paraMap); foreach ($paraMap as $k => $v){ if($urlencode) { $v = urlencode($v); } $buff .= $k . "=" . $v . "&"; } $reqPar; if (strlen($buff) > 0){ $reqPar = substr($buff, 0, strlen($buff)-1); } return $reqPar; } }
