Cet article contient beaucoup de contenu, notamment l'accès à WeChat, l'obtention d'informations sur les utilisateurs WeChat, le paiement WeChat et l'obtention des paramètres de configuration JSSDK. Si le lecteur n'a pas une compréhension subjective du développement de WeChat, il est recommandé qu'il étudie d'abord la Documentation du développeur de la plateforme publique WeChat, puis de lire cet article pour de meilleurs résultats ! De plus, la version chapitre par section de cet article est disponible sur le blog de Babao Porridge.
1. Configurez les paramètres du jeton dans app/config/params.php
return [ //微信接入 'wechat' =>[ 'token' => 'your token', ], ];
2. . Configurez le routage
dans app/config/main.php car le module d'interface utilise l'API RESTful, vous devez donc définir des règles de routage . .
'urlManager' => [ 'enablePrettyUrl' => true, 'enableStrictParsing' => true, 'showScriptName' => false, 'rules' => [ [ 'class' => 'yii\rest\UrlRule', 'controller' => 'wechat', 'extraPatterns' => [ 'GET valid' => 'valid', ], ], ], ],
3. Créez un nouveau WechatController dans app/controllers
<?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; } } } }
Configurez l'URL et le jeton en arrière-plan du compte officiel WeChat. , puis soumettez-le. Vérifiez simplement.
URL:http://app.demo.com/wechats/valid Token:your token
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`);
Interface d'autorisation utilisateur : obtenir access_token , openid, etc. ; obtenir et enregistrer les informations utilisateur dans la base de données
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. Obtenir les informations utilisateur de WeChat
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 $result; }
3. Obtenir l'interface d'informations utilisateur
public function actionUserinfo() { if(isset($_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 $result; }Paiement WeChat1. Interface de paiement WeChat : données de paiement packagées
public function actionPay(){ if(isset($_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.
