网上有很多关于YII2.0微信开发教程,但是太过复杂凌乱,所以今天在这里给大家整理总结利用Yii2微信后台开发的系列了,给需要的小伙伴们参考。
一:接入微信
Yii2后台配置
1.在app/config/params.php中配置token参数
return [ //微信接入 'wechat' =>[ 'token' => 'your token', ], ];
2.在app/config/main.php中配置路由
因为接口模块使用的RESTful API,所以需要定义路由规则。
'urlManager' => [ 'enablePrettyUrl' => true, 'enableStrictParsing' => true, 'showScriptName' => false, 'rules' => [ [ 'class' => 'yii\rest\UrlRule', 'controller' => 'wechat', 'extraPatterns' => [ 'GET valid' => 'valid', ], ], ], ],
3.在app/controllers中新建WechatController
<?php namespace 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; } } } }
微信公众号后台配置
在微信公众号后台配置URL和Token,然后提交验证即可。
URL:http://app.demo.com/wechats/valid Token:your token
二:获取用户信息
用户表设计
代码如下:
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 '微信昵称', `sex` tinyint(4) NOT NULL COMMENT '性别', `headimgurl` varchar(255) COLLATE utf8_unicode_ci NOT NULL COMMENT '头像', `country` varchar(50) COLLATE utf8_unicode_ci NOT NULL COMMENT '国家', `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`);
获取用户信息的相关接口
1.用户授权接口:获取access_token、openId等;获取并保存用户资料到数据库
代码如下:
public function actionAccesstoken() { $code = $_GET["code"]; $state = $_GET["state"]; $appid = Yii::$app->params['wechat']['appid']; $appsecret = Yii::$app->params['wechat']['appsecret']; $request_url = '/tupian/20230522/access_token //初始化一个curl会话 $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $request_url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($ch); curl_close($ch); $result = $this->response($result); //获取token和openid成功,数据解析 $access_token = $result['access_token']; $refresh_token = $result['refresh_token']; $openid = $result['openid']; //请求微信接口,获取用户信息 $userInfo = $this->getUserInfo($access_token,$openid); $user_check = WechatUser::find()->where(['openid'=>$openid])->one(); if ($user_check) { //更新用户资料 } else { //保存用户资料 } //前端网页的重定向 if ($openid) { return $this->redirect($state.$openid); } else { return $this->redirect($state); } }
2.从微信获取用户资料
代码如下:
public function getUserInfo($access_token,$openid) { $request_url = '/tupian/20230522/userinfo //初始化一个curl会话 $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $request_url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($ch); curl_close($ch); $result = $this->response($result); return $result; }
3.获取用户资料接口
public function actionUserinfo() { if(isset($_REQUEST["openid"])){ $openid = $_REQUEST["openid"]; $user = WechatUser::find()->where(['openid'=>$openid])->one(); if ($user) { $result['error'] = 0; $result['msg'] = '获取成功'; $result['user'] = $user; } else { $result['error'] = 1; $result['msg'] = '没有该用户'; } } else { $result['error'] = 1; $result['msg'] = 'openid为空'; } return $result; }
三:微信支付
1.微信支付接口:打包支付数据
代码如下:
public function actionPay(){ if(isset($_REQUEST["uid"])&&isset($_REQUEST["oid"])&&isset($_REQUEST["totalFee"])){ //uid、oid、totalFee $uid = $_REQUEST["uid"]; $oid = $_REQUEST["oid"]; $totalFee = $_REQUEST["totalFee"]; $timestamp = time(); //微信支付参数 $appid = Yii::$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'] = '请求参数错误'; } return $result; }
2.接收微信发送的异步支付结果通知
代码如下:
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); } //微信支付参数 $appid = Yii::$app->params['wechat']['appid']; $mchid = Yii::$app->params['wechat']['mchid']; $key = Yii::$app->params['wechat']['key']; $wx_pay = new WechatPay($mchid, $appid, $key); //验证签名 $arr = (array)$postObj; unset($arr['sign']); if ($wx_pay->getSign($arr, $key) != $postObj->sign) { die("签名错误"); } //支付处理正确-判断是否已处理过支付状态 $orders = Order::find()->where(['uid'=>$postObj->openid, 'oid'=>$postObj->out_trade_no, 'status' => 0])->all(); if(count($orders) > 0){ //更新订单状态 foreach ($orders as $order) { //更新订单 $order['status'] = 1; $order->update(); } return '<xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml>'; } else { //订单状态已更新,直接返回 return '<xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml>'; } }
3.微信支付类 WechatPay.php
代码如下:
<?php namespace 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('/tupian/20230522/unifiedorder& $unifiedOrder = simplexml_load_string($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, $options); } //https请求 不验证证书和host curl_setopt($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); //设置cURL允许执行的最长秒数 if (!empty($options)) { curl_setopt_array($ch, $options); } //https请求 不验证证书和host curl_setopt($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 $reqPar; } }
四:获取JS-SDK的config参数
根据微信公众平台开发者文档:
所有需要使用JS-SDK的页面必须先注入配置信息,否则将无法调用(同一个url仅需调用一次,对于变化url的SPA的web app可在每次url变化时进行调用,目前Android微信客户端不支持pushState的H5新特性,所以使用pushState来实现web app的页面会导致签名失败,此问题会在Android6.2中修复)。
即:
代码如下:
wx.config({ debug: true, // 开启调试模式,调用的所有api的返回值会在客户端alert出来,若要查看传入的参数,可以在pc端打开,参数信息会通过log打出,仅在pc端时才会打印。 appId: '', // 必填,公众号的标识 timestamp: , // 必填,生成签名的时间戳 nonceStr: '', // 必填,生成签名的随机串 signature: '',// 必填,签名,见附录1 jsApiList: [] // 必填,需要使用的JS接口列表,所有JS接口列表见附录2 });
1.微信支付类 WechatPay.php
代码如下:
<?php namespace api\sdk; use Yii; class WechatPay { public function getSignPackage($url) { $jsapiTicket = self::getJsApiTicket(); $timestamp = time(); $nonceStr = self::createNonceStr(); // 这里参数的顺序要按照 key 值 ASCII 码升序排序 $string = "jsapi_ticket=".$jsapiTicket."&noncestr=".$nonceStr."×tamp=".$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缓存 jsapi_ticket $redis = Yii::$app->redis; $redis_ticket = $redis->get('wechat:jsapi_ticket'); if ($redis_ticket) { $ticket = $redis_ticket; } else { $accessToken = self::getAccessToken(); $url = "/tupian/20230522/getticket $res = json_decode(self::curlGet($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缓存 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 = "/tupian/20230522/token $res = json_decode(self::curlGet($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, $options); } //https请求 不验证证书和host curl_setopt($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); //设置cURL允许执行的最长秒数 if (!empty($options)) { curl_setopt_array($ch, $options); } //https请求 不验证证书和host curl_setopt($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 $str; } }
2.获取config参数接口
public function actionConfig(){ if (isset($_REQUEST['url'])) { $url = $_REQUEST['url']; //微信支付参数 $appid = Yii::$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'] = '获取成功'; $result['config'] = $package; } else { $result['error'] = 1; $result['msg'] = '参数错误'; } return $result; }
