關於利用Yii2微信後台開發的解析

這篇文章主要介紹了關於利用Yii2後台開發的解析，有著一定的參考價值，現在分享給大家，有需要的朋友可以參考一下

Yii2是一個高效能，基於組件的 PHP 架構，這篇文章詳細的給大家介紹了利用Yii2開發後台。我們一起來看看。

網上有很多關於YII2.0開發教程，但是太過複雜淩亂，所以今天在這裡給大家整理總結利用Yii2後台開發的系列了，給需要的小夥伴們參考。

一：接入

Yii2後台配置

1.在app/config/params.php中配置token參數

return [ //接入 'wechat' =>[ 'token' => 'your token', ],];

2.在app/config/main.php中配置路由

因為介面模組使用的RESTful API，所以需要定義路由規則。

'urlManager' => [ 'enablePrettyUrl' => true, 'enableStrictParsing' => true, 'showScriptName' => false, 'rules' => [ [  'class' => 'yii\rest\UrlRule',  'controller' => 'wechat',  'extraPatterns' => [  'GET valid' => 'valid',  ], ], ],],

3.在app/controllers中建立WechatController

<?phpnamespace api\controllers;use Yii;use yii\rest\ActiveController;class WechatController extends ActiveController{ public $modelClass = ''; public function actionValid() { $echoStr = $_GET["echostr"]; $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; //valid signature , option if($this->checkSignature($signature,$timestamp,$nonce)){  echo $echoStr; } } private function checkSignature($signature,$timestamp,$nonce) { // you must define TOKEN by yourself $token = Yii::$app->params['wechat']['token']; if (!$token) {  echo 'TOKEN is not defined!'; } else {  $tmpArr = array($token, $timestamp, $nonce);  // use SORT_STRING rule  sort($tmpArr, SORT_STRING);  $tmpStr = implode( $tmpArr );  $tmpStr = sha1( $tmpStr );  if( $tmpStr == $signature ){  return true;  }else{  return false;  } } }}

公眾號後台配置

在公眾號後台配置URL和Token，然後提交驗證即可。

URL:http://app.demo.com/wechats/validToken:your token

二：擷取使用者資訊

使用者表設計

CREATE TABLE `wechat_user` (  `id` int(11) NOT NULL,  `openid` varchar(255) COLLATE utf8_unicode_ci NOT NULL,  `nickname` varchar(50) COLLATE utf8_unicode_ci NOT NULL COMMENT '暱稱',  `sex` tinyint(4) NOT NULL COMMENT '性別',  `headimgurl` varchar(255) COLLATE utf8_unicode_ci NOT NULL COMMENT '頭像',  `country` varchar(50) COLLATE utf8_unicode_ci NOT NULL COMMENT '國家',  `province` varchar(50) COLLATE utf8_unicode_ci NOT NULL COMMENT '省份',  `city` varchar(50) COLLATE utf8_unicode_ci NOT NULL COMMENT '城市',  `access_token` varchar(255) COLLATE utf8_unicode_ci NOT NULL,  `refresh_token` varchar(255) COLLATE utf8_unicode_ci NOT NULL,  `created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;ALTER TABLE `wechat_user`  ADD PRIMARY KEY (`id`);

擷取使用者資訊的相關介面

1.使用者授權介面：擷取access_token、openId等；擷取並儲存使用者資料到資料庫

public function actionAccesstoken(){    $code = $_GET["code"];    $state = $_GET["state"];    $appid = Yii::$app->params['wechat']['appid'];    $appsecret = Yii::$app->params['wechat']['appsecret'];    $request_url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$appid.'&secret='.$appsecret.'&code='.$code.'&grant_type=authorization_code';    //初始化一個curl會話    $ch = curl_init();    curl_setopt($ch, CURLOPT_URL, $request_url);    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    $result = curl_exec($ch);    curl_close($ch);    $result = $this->response($result);    //擷取token和openid成功，資料解析    $access_token = $result['access_token'];    $refresh_token = $result['refresh_token'];    $openid = $result['openid'];    //請求介面，擷取使用者資訊    $userInfo = $this->getUserInfo($access_token,$openid);    $user_check = WechatUser::find()->where(['openid'=>$openid])->one();    if ($user_check) {        //更新使用者資料    } else {        //儲存使用者資料    }    //前端網頁的重新導向    if ($openid) {        return $this->redirect($state.$openid);    } else {        return $this->redirect($state);    }}

2.從擷取使用者資料

public function getUserInfo($access_token,$openid){    $request_url = 'https://api.weixin.qq.com/sns/userinfo?access_token='.$access_token.'&openid='.$openid.'&lang=zh_CN';    //初始化一個curl會話    $ch = curl_init();    curl_setopt($ch, CURLOPT_URL, $request_url);    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    $result = curl_exec($ch);    curl_close($ch);    $result = $this->response($result);    return $result;}

3.擷取使用者資料介面

public function actionUserinfo(){ if(isset($_REQUEST["openid"])){  $openid = $_REQUEST["openid"];  $user = WechatUser::find()->where(['openid'=>$openid])->one();  if ($user) {   $result['error'] = 0;   $result['msg'] = '擷取成功';   $result['user'] = $user;  } else {   $result['error'] = 1;   $result['msg'] = '沒有該使用者';  } } else {  $result['error'] = 1;  $result['msg'] = 'openid為空白'; } return $result;}

三：支付

1.支付介面：打包支付資料

public function actionPay(){    if(isset($_REQUEST["uid"])&&isset($_REQUEST["oid"])&&isset($_REQUEST["totalFee"])){        //uid、oid、totalFee        $uid = $_REQUEST["uid"];        $oid = $_REQUEST["oid"];        $totalFee = $_REQUEST["totalFee"];        $timestamp = time();        //支付參數        $appid = Yii::$app->params['wechat']['appid'];        $mchid = Yii::$app->params['wechat']['mchid'];        $key = Yii::$app->params['wechat']['key'];        $notifyUrl = Yii::$app->params['wechat']['notifyUrl'];        //支付打包        $wx_pay = new WechatPay($mchid, $appid, $key);        $package = $wx_pay->createJsBizPackage($uid, $totalFee, $oid, $notifyUrl, $timestamp);        $result['error'] = 0;        $result['msg'] = '支付打包成功';        $result['package'] = $package;        return $result;    }else{        $result['error'] = 1;        $result['msg'] = '請求參數錯誤';    }    return $result;}

2.接收發送的非同步支付結果通知

public function actionNotify(){    $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];    $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);    //    if ($postObj === false) {        die('parse xml error');    }    if ($postObj->return_code != 'SUCCESS') {        die($postObj->return_msg);    }    if ($postObj->result_code != 'SUCCESS') {        die($postObj->err_code);    }    //支付參數    $appid = Yii::$app->params['wechat']['appid'];    $mchid = Yii::$app->params['wechat']['mchid'];    $key = Yii::$app->params['wechat']['key'];    $wx_pay = new WechatPay($mchid, $appid, $key);    //驗證簽名    $arr = (array)$postObj;    unset($arr['sign']);    if ($wx_pay->getSign($arr, $key) != $postObj->sign) {        die("簽名錯誤");    }    //支付處理正確-判斷是否已處理過支付狀態    $orders = Order::find()->where(['uid'=>$postObj->openid, 'oid'=>$postObj->out_trade_no, 'status' => 0])->all();    if(count($orders) > 0){        //更新訂單狀態        foreach ($orders as $order) {            //更新訂單            $order['status'] = 1;            $order->update();        }        return '<xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml>';    } else {        //訂單狀態已更新，直接返回        return '<xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml>';    }}

3.支付類 WechatPay.php

<?phpnamespace api\sdk;use Yii;class WechatPay{    protected $mchid;    protected $appid;    protected $key;    public function __construct($mchid, $appid, $key){        $this->mchid = $mchid;        $this->appid = $appid;        $this->key = $key;    }    public function createJsBizPackage($openid, $totalFee, $outTradeNo, $orderName, $notifyUrl, $timestamp){        $config = array(            'mch_id' => $this->mchid,            'appid' => $this->appid,            'key' => $this->key,        );        $unified = array(            'appid' => $config['appid'],            'attach' => '支付',            'body' => $orderName,            'mch_id' => $config['mch_id'],            'nonce_str' => self::createNonceStr(),            'notify_url' => $notifyUrl,            'openid' => $openid,            'out_trade_no' => $outTradeNo,            'spbill_create_ip' => '127.0.0.1',            'total_fee' => intval($totalFee * 100),            'trade_type' => 'JSAPI',        );        $unified['sign'] = self::getSign($unified, $config['key']);        $responseXml = self::curlPost('https://api.mch.weixin.qq.com/pay/unifiedorder', self::arrayToXml($unified));        $unifiedOrder = simplexml_load_string($responseXml, 'SimpleXMLElement', LIBXML_NOCDATA);        if ($unifiedOrder === false) {            die('parse xml error');        }        if ($unifiedOrder->return_code != 'SUCCESS') {            die($unifiedOrder->return_msg);        }        if ($unifiedOrder->result_code != 'SUCCESS') {            die($unifiedOrder->err_code);        }        $arr = array(            "appId" => $config['appid'],            "timeStamp" => $timestamp,            "nonceStr" => self::createNonceStr(),            "package" => "prepay_id=" . $unifiedOrder->prepay_id,            "signType" => 'MD5',        );        $arr['paySign'] = self::getSign($arr, $config['key']);        return $arr;    }    public static function curlGet($url = '', $options = array()){        $ch = curl_init($url);        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        curl_setopt($ch, CURLOPT_TIMEOUT, 30);        if (!empty($options)) {            curl_setopt_array($ch, $options);        }        //https請求 不驗證認證和host        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);        $data = curl_exec($ch);        curl_close($ch);        return $data;    }    public static function curlPost($url = '', $postData = '', $options = array()){        if (is_array($postData)) {            $postData = http_build_query($postData);        }        $ch = curl_init();        curl_setopt($ch, CURLOPT_URL, $url);        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        curl_setopt($ch, CURLOPT_POST, 1);        curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);        curl_setopt($ch, CURLOPT_TIMEOUT, 30); //設定cURL允許執行的最長秒數        if (!empty($options)) {            curl_setopt_array($ch, $options);        }        //https請求 不驗證認證和host        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);        $data = curl_exec($ch);        curl_close($ch);        return $data;    }    public static function createNonceStr($length = 16){        $chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';        $str = '';        for ($i = 0; $i<$length; $i++){            $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);        }        return $str;    }    public static function arrayToXml($arr){        $xml = "<xml>";        foreach ($arr as $key => $val){            if (is_numeric($val)) {                $xml .= "<" . $key . ">" . $val . "</" . $key . ">";            } else {                $xml .= "<" . $key . "><![CDATA[" . $val . "]]></" . $key . ">";            }        }        $xml .= "</xml>";        return $xml;    }    public static function getSign($params, $key){        ksort($params, SORT_STRING);        $unSignParaString = self::formatQueryParaMap($params, false);        $signStr = strtoupper(md5($unSignParaString . "&key=" . $key));        return $signStr;    }    protected static function formatQueryParaMap($paraMap, $urlEncode = false){        $buff = "";        ksort($paraMap);        foreach ($paraMap as $k => $v){            if (null != $v && "null" != $v) {                if ($urlEncode) {                    $v = urlencode($v);                }                $buff .= $k . "=" . $v . "&";            }        }        $reqPar = '';        if (strlen($buff)>0) {            $reqPar = substr($buff, 0, strlen($buff) - 1);        }        return $reqPar;    }}

四：擷取JS-SDK的config參數

根據公眾平台開發人員文檔：

所有需要使用JS-SDK的頁面必須先注入配置資訊，否則將無法調用（同一個url僅需調用一次，對於變化url的SPA的web app可在每次url變化時進行調用,目前Android用戶端不支援pushState的H5新特性，所以使用pushState來實現web app的頁面會導致簽名失敗，此問題會在Android6.2中修複）。

即：

wx.config({    debug: true, // 開啟偵錯模式,調用的所有api的傳回值會在用戶端alert出來，若要查看傳入的參數，可以在pc端開啟，參數資訊會通過log打出，僅在pc端時才會列印。    appId: '', // 必填，公眾號的唯一標識    timestamp: , // 必填，產生簽名的時間戳記    nonceStr: '', // 必填，產生簽名的隨機串    signature: '',// 必填，簽名，見附錄1    jsApiList: [] // 必填，需要使用的JS介面列表，所有JS介面列表見附錄2});

1.支付類 WechatPay.php

<?phpnamespace api\sdk;use Yii;class WechatPay{    public function getSignPackage($url) {        $jsapiTicket = self::getJsApiTicket();        $timestamp = time();        $nonceStr = self::createNonceStr();        // 這裡參數的順序要按照 key 值 ASCII 碼升序排序        $string = "jsapi_ticket=".$jsapiTicket."&noncestr=".$nonceStr."&timestamp=".$timestamp."&url=".$url;        $signature = sha1($string);        $signPackage = array(            "appId"     => $this->appid,            "nonceStr"  => $nonceStr,            "timestamp" => $timestamp,            "url"       => $url,            "signature" => $signature,            "rawString" => $string        );        return $signPackage;    }    public static function getJsApiTicket() {        //使用Redis緩衝 jsapi_ticket        $redis = Yii::$app->redis;        $redis_ticket = $redis->get('wechat:jsapi_ticket');        if ($redis_ticket) {            $ticket = $redis_ticket;        } else {            $accessToken = self::getAccessToken();            $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=".$accessToken;            $res = json_decode(self::curlGet($url));            $ticket = $res->ticket;            if ($ticket) {                $redis->set('wechat:jsapi_ticket', $ticket);                $redis->expire('wechat:jsapi_ticket', 7000);            }        }        return $ticket;    }    public static function getAccessToken() {        //使用Redis緩衝 access_token        $redis = Yii::$app->redis;        $redis_token = $redis->get('wechat:access_token');        if ($redis_token) {            $access_token = $redis_token;        } else {            $appid = Yii::$app->params['wechat']['appid'];            $appsecret = Yii::$app->params['wechat']['appsecret'];            $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appid."&secret=".$appsecret;            $res = json_decode(self::curlGet($url));            $access_token = $res->access_token;            if ($access_token) {                $redis->set('wechat:access_token', $access_token);                $redis->expire('wechat:access_token', 7000);            }        }        return $access_token;    }    public static function curlGet($url = '', $options = array()){        $ch = curl_init($url);        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        curl_setopt($ch, CURLOPT_TIMEOUT, 30);        if (!empty($options)) {            curl_setopt_array($ch, $options);        }        //https請求 不驗證認證和host        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);        $data = curl_exec($ch);        curl_close($ch);        return $data;    }    public static function curlPost($url = '', $postData = '', $options = array()){        if (is_array($postData)) {            $postData = http_build_query($postData);        }        $ch = curl_init();        curl_setopt($ch, CURLOPT_URL, $url);        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        curl_setopt($ch, CURLOPT_POST, 1);        curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);        curl_setopt($ch, CURLOPT_TIMEOUT, 30); //設定cURL允許執行的最長秒數        if (!empty($options)) {            curl_setopt_array($ch, $options);        }        //https請求 不驗證認證和host        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);        $data = curl_exec($ch);        curl_close($ch);        return $data;    }    public static function createNonceStr($length = 16){        $chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';        $str = '';        for ($i = 0; $i<$length; $i++){            $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);        }        return $str;    }}

2.擷取config參數介面

public function actionConfig(){ if (isset($_REQUEST['url'])) { $url = $_REQUEST['url']; //支付參數 $appid = Yii::$app->params['wechat']['appid']; $mchid = Yii::$app->params['wechat']['mchid']; $key = Yii::$app->params['wechat']['key']; $wx_pay = new WechatPay($mchid, $appid, $key); $package = $wx_pay->getSignPackage($url); $result['error'] = 0; $result['msg'] = '擷取成功'; $result['config'] = $package; } else { $result['error'] = 1; $result['msg'] = '參數錯誤'; } return $result;}
