實(shí)現(xiàn)思路

生成一個(gè)二維碼，加入要處理的url連接 在用戶掃完碼后，在對(duì)應(yīng)的腳本中，判斷掃碼終端，調(diào)用相應(yīng)的支付 若能夠掃碼之后能喚起相應(yīng)app，支付寶要用手機(jī)網(wǎng)站支付方式，微信要使用jsapi支付方式

效果展示

提示： 因?yàn)轫?xiàng)目即將上線，所以上面的支付二維碼連接被我替換了(注意在生成二維碼時(shí)加入的連接，要帶上http協(xié)議)

實(shí)現(xiàn)

步驟生成二維碼

//我的url指向了checkTerrace方法$url = self::ADMIN_URL . ’params=’ . $params; //ADMIN_URL是生成二維碼的url，請(qǐng)?zhí)鎿Q成自己

處理用戶掃碼操作(checkTerrace方法)

public function checkTerrace() { $pay_type = $this->getPayType(); //該方法使用來判斷用戶掃碼終端的 $params = $this->request->get(’params’); //生成二維碼url帶的參數(shù)(看個(gè)人需求，我的項(xiàng)目需要額外參數(shù)) $params = $this->desDecode($params); //這里是因?yàn)槲覍?duì)參數(shù)進(jìn)行了desc加密，看個(gè)人需求 if ($pay_type === ’alipay’) { //如果用戶是通過支付寶掃碼，進(jìn)行支付寶相關(guān)操作 if ($params === false) { echo '系統(tǒng)錯(cuò)誤!，請(qǐng)稍后重試'; exit; } $res = $this->createOrder($pay_type, $params); if (!$res) { echo '系統(tǒng)錯(cuò)誤，請(qǐng)稍后重試'; exit; } $this->aliPay($res); } elseif ($pay_type === ’wechat’) { //如果用戶是通過微信掃碼，進(jìn)行微信相關(guān)操作 if ($params === false) { echo '系統(tǒng)錯(cuò)誤，請(qǐng)稍后重試'; exit; } $prepare = $this->wechat($pay_type, $params); $this->assign(’json’, $prepare); return $this->display(’wpay.html’); } elseif ($pay_type === false) { echo '請(qǐng)使用支付寶或微信進(jìn)行掃碼'; exit; } }

判斷掃碼終端

/** * 判斷掃碼終端 * * @return string|boolean * @date 2021-02-04 */ private function getPayType() { if (strstr($_SERVER[’HTTP_USER_AGENT’], ’AlipayClient’)) { return 'alipay'; } elseif (strstr($_SERVER[’HTTP_USER_AGENT’], ’MicroMessenger’)) { return 'wechat'; } else { return false; } }

生成訂單

/** * 生成訂單 * * @param string $pay_type * @param json $params * @return void * @date 2021-02-04 */ //這個(gè)邏輯就不貼代碼了 private function createOrder($pay_type, $params) { /*生成訂單相關(guān)邏輯代碼*/ }

支付寶支付

/** * 喚起支付寶app * * @param array $api_params * @return void * @date 2021-02-04 */ private function aliPay($api_params) { $config = [ ’notify_url’ => ’異步回調(diào)地址’, ’is_open_certificate’ => true ]; $domain = urlencode($api_params[’domain’]); $api = [ ’out_trade_no’ => $api_params[’trade_no’], ’total_amount’ => ’0.01’, ’subject’ => ’商品標(biāo)題’, ’passback_params’ => $domain ]; $pay = new Pay($config); $res = $pay->driver(’alipay’)->gateway(’wap’)->pay($api); //調(diào)用支付寶手機(jī)網(wǎng)站支付 echo $res; }

微信支付

/** * 喚起微信app * * @return void * @date 2021-02-04 */ public function wechat($pay_type, $params) { $opend_id = $this->getOpenId(); //處理微信jsapi支付之前，要先獲取用戶的openID if (!$opend_id) { echo '微信授權(quán)失敗...'; exit; } $api_params = $this->createOrder($pay_type, $params); //用戶openID獲取成功后才進(jìn)行訂單生產(chǎn)操作 if (!$api_params) { echo '系統(tǒng)錯(cuò)誤，請(qǐng)稍后重試'; exit; } $config = [’notify_url’ => ’微信異步回調(diào)地址’]; $api = [ ’body’ => ’我是標(biāo)題’, ’out_trade_no’ => $api_params[’trade_no’], ’total_fee’ => 1,’openid’ => $opend_id, ’attach’ => $api_params[’domain’] ]; $pay = new Pay($config); $res = $pay->driver(’wechat’)->gateway(’mp’)->pay($api); //調(diào)用微信jsapi支付 return $res; }

靜默獲取openID

/** * 獲取用戶的openid * * @return void * @date 2021-02-04 */ public function getOpenId() { if (isset($_SESSION[’open_id’]) && $_SESSION[’open_id’]) { return $_SESSION[’open_id’]; } if (!$this->request->get(’code’)) { $redirect_uri = $_SERVER[’REQUEST_SCHEME’] . ’://’ . $_SERVER[’HTTP_HOST’] . $_SERVER[’REQUEST_URI’]; //這里授權(quán)后微信跳轉(zhuǎn)的地址，要寫在訂單處理處，否則會(huì)造成因?yàn)槌绦蛱D(zhuǎn)到微信授權(quán)頁面，導(dǎo)致腳本邏輯終止 $redirect_uri = urlencode($redirect_uri); $url = $this->codeUrl . ’redirect_uri=’ . $redirect_uri . ’&appid=’ . $this->appId . ’&scope=snsapi_base&response_type=code&state=STATE#wechat_redirect’; //使用用戶靜默授權(quán)模式(因?yàn)槲也恍枰@取用戶信息所有就沒采用用戶手段授權(quán)模式) header('location:{$url}'); //跳轉(zhuǎn)到微信授權(quán)頁面 } else { $openidurl = $this->openidUrl . ’appid=’ . $this->appId . ’&secret=’ . $this->appSecret . ’&code=’ . $this->request->get(’code’) . ’&grant_type=authorization_code’; $data = Http::get($openidurl); $data = json_decode($data, true); if ($data[’openid’]) { $_SESSION[’open_id’] = $data[’openid’]; //獲取到的用戶openID存儲(chǔ)到session中 } else {$_SESSION[’open_id’] = false; } return $_SESSION[’open_id’]; } }

前端效果：

用戶進(jìn)入支付頁面但是一直為掃碼，超過一定時(shí)間

用戶掃碼后一直未進(jìn)行支付，超過一定時(shí)間
