一、功能简要介绍

1、根据需求，用户在美团大众点评中所购买的门票在自己的系统上可以核销，同时把核销信息存储到自己的系统里。2、美团点评API文档地址：[https://open.dianping.com/document/v2?rootDocId=5000](https://open.dianping.com/document/v2?rootDocId=5000)

二、开发步骤：

1、用点评管家账号登录文档，相应文档说明：https://open.dianping.com/document/v2?docId=6000136&rootDocId=1000

2 、选好自己相应的应用型，审核通过之后，就可以用平台系统的测试的数据就行接口调用

3、在大众点评app购买相应票，根据验券核销API文档（根据业务需求选择的类型是自用型）调取查询券、验券即核销券的接口。
代码如下：

//查询券、验券public function prepare(){//  $arr 为数组  里面为应用参数$appKey = "1ef04****e3a8";  //key$secret = "dd8a291f9f*****4e3fbd9be6ff";  //秘钥$timestamp = date('Y-m-d H:i:s');$format = 'json';$v = 1;$sign_method = 'MD5';$qr_code = '257***4228';$open_shop_uuid = '34d5902420ca****48e941a38d773';$session = 'bbf7059256aaf3f1****3b4d9c0816cf819b7';$data = ['app_key' => $appKey,'timestamp' => $timestamp,'sign_method' => $sign_method,'format' => $format,'v' => $v,'session' => $session,];$arr = ['requestid'=>'123','receipt_code' => $qr_code,//'qr_code'=>$qr_code,'open_shop_uuid' => $open_shop_uuid,//'count'=>1,//'app_shop_account' =>'test',// 'app_shop_accountname' =>'test1',];$data = array_merge($data, $arr);ksort($data);$sign = $this->cal_sign($secret, $data);//获取签名$data['sign'] = $sign;
//        $data['count'] = $sign;
//        $data['app_shop_account'] = $sign;
//        $data['app_shop_accountname'] = $sign;$data = array_merge($data, $arr);$postdata = http_build_query($data);$url = 'https://openapi.dianping.com/router/tuangou/receipt/prepare';//输码查询券//$url = 'https://openapi.dianping.com/router/tuangou/receipt/scanprepare';//扫码查询券//$url = 'https://openapi.dianping.com/router/tuangou/receipt/consume';//验券$tmpInfo=$this->curl_post($url,$postdata);var_dump($tmpInfo);}/*** 计算签名** @param $app_secret 三方app_secret* @param $req_param 请求参数集合，包括公共参数和业务参数* @return string md5签名*/function cal_sign($app_secret, $req_param){// 排序所有请求参数ksort($req_param);$src_value = "";// 按照key1value1key2value2...keynvaluen拼接foreach ($req_param as $key => $value) {$src_value .= ($key . $value);}//计算md5return md5($app_secret . $src_value . $app_secret);}//post请求private function curl_post($url,$postdata){$curl = curl_init(); // 启动一个CURL会话curl_setopt($curl, CURLOPT_URL, $url); // 要访问的地址curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); // 对认证证书来源的检测curl_setopt($curl, CURLOPT_HTTPHEADER, array('Expect:')); // 解决数据包大不能提交curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转curl_setopt($curl, CURLOPT_AUTOREFERER, 1); // 自动设置Referercurl_setopt($curl, CURLOPT_POST, 1); // 发送一个常规的Post请求curl_setopt($curl, CURLOPT_POSTFIELDS, $postdata); // Post提交的数据包curl_setopt($curl, CURLOPT_TIMEOUT, 30); // 设置超时限制防止死循curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回

运用平台提供的相应参数，流程能顺利走通。

4、当放到线上的时候，选择相应的进行上线，首先要去平台“我的应用”设置回调地址，然后再授权地址上加上回调地址，还要进行授权去获取session，然后通过session去获取店铺的id
回调地址：
授权地址：
5、授权地址：

https://e.dianping.com/dz-open/merchant/auth?app_key=1ef0e3a8&redirect_url=https:///admin/Dian/get_auth&state=teststate&scope=[%22tuangou%22]
授权地址可以获取auth_code,根据这个值去换取session，换取session后可以去换取店铺id

//获取auth_codepublic function get_auth(){$auth_code = input('auth_code');if(!isset($auth_code)) {$app_key='1ef*****3a8';$state='teststate';$redirect_url='https://****/admin/Dian/get_auth';$scope='tuangou';$url='https://e.dianping.com/dz-open/merchant/auth?';$data=['app_key' =>$app_key,'state' => $state,'redirect_url' =>$redirect_url,'scope' =>$scope,];$postdata = http_build_query($data);Header("Location: $url$postdata");} else {var_dump($auth_code);die();}}//获取sessionpublic function get_session(){$app_key='1ef0*****e3a8';$app_secret='dd8a291******bd9be6ff';$auth_code='4e027519e******a6a9d1ee5f2';$grant_type='authorization_code';$redirect_url='https://*****/admin/Dian/get_auth';$data=['app_key' =>$app_key,'app_secret' => $app_secret,'redirect_url' =>$redirect_url,'auth_code' =>$auth_code,'grant_type' =>$grant_type];$postdata = http_build_query($data);$url='https://openapi.dianping.com/router/oauth/token';$tmpInfo=$this->curl_post($url,$postdata);var_dump($tmpInfo);}//获取所有店铺的idpublic function get_shopid(){$app_key='1ef04*****e3a8';$secret = "dd8a29*****fbd9be6ff";  //秘钥$sign_method='MD5';$timestamp = date('Y-m-d H:i:s');$format = 'json';$v = 1;//$session = 'f44d594ab895c******85b70bade02c';$session = 'bbf7059256aaf3*******0816cf819b7';$bid='5da1aab********5ad457a2c';//和session一起返回的$offset =0;$limit = 20;$url='https://openapi.dianping.com/router/oauth/session/scope?';$data=['app_key' =>$app_key,'sign_method' => $sign_method,'timestamp' =>$timestamp,'format' =>$format,'v' =>$v,'session' =>$session,'bid' =>$bid,'offset' =>$offset,'limit' =>$limit,];ksort($data);$sign = $this->cal_sign($secret, $data);$data['sign'] = $sign;$postdata = http_build_query($data);$tmpInfo=$this->curl_get($url.$postdata);var_dump($tmpInfo);}

有需要的朋友可以试一下。本人没有试过，但是可以用。以前用到过。
