好久没有更新文章了。不知道关注我的小伙伴们是不是已经不在关注我了。最近在忙着一些推广运营的事情，所以没有更新，
这几天接到一个项目，需要对接美团API接口，实现核销功能。现在就来给大家展示具体代码，
public function tuangou_hexiao(){ // $qr_cpde = $_GET['qr_code']; $open_shop_uuid = $_GET['open_shop_uuid']; // $arr 为数组 里面为应用参数 $appKey = "111111111"; $secret = "11111111111111111"; //秘钥 $timestamp = date('Y-m-d H:i:s'); $format = 'json'; $v = 1; $sign_method = 'MD5'; //因为功能要实现在小程序，所以获取的必要信息要存在文件中，有必要时拿出来 //不是必要行为， $file = $this->readFile(); $data = [ 'app_key' => $appKey, 'timestamp' => $timestamp, 'sign_method' => $sign_method, 'format' => $format, 'v' => $v, //此处的session值，我原本是存在文件中的， //如果你不需要存文件，那你就当做参数传递过来 'session' => $file['session'], ]; //根据不同的操作类型配置不同的参数 //具体参数含义见 https://open.dianping.com/document/v2?docId=6000176&rootDocId=5000 if($_GET['type']=='save'){ $arr = [ 'requestid' => '123', 'count'=>1, 'receipt_code' => $qr_cpde, 'open_shop_uuid' => $open_shop_uuid, 'app_shop_account' => '账号', 'app_shop_accountname' => '账号名称', ];

}}这段代码是实现美团核销的功能。 亲测有效，如果有小伙伴需要的话，可否动动你的手指，给我点个关注呢。
