业务场景

微信提现使用场景一般为用户客户端发起提现申请，服务端收到请求后调用微信Api发起微信提现。然后通过查询提现结果接口确认一下即可。

接口介绍

https://api.mch./mmpaymkttransfers/promotion/transfers

特别注意：该接口对微信商户有如下要求：

商户号已入驻90日且截止今日回推30天商户号保持连续不间断的交易。

接入流程

第一步

登录微信商户平台，配置一下（配置微信商户流程），获取商户号、支付密钥、证书文件；点击产品中心–我的产品开通企业付款到零钱的功能；

第二步

调用接口发起提现申请，上代码（不喜勿喷）：

//接口地址$url = "https://api.mch./mmpaymkttransfers/promotion/transfers";//参数$param = [];$param['mch_appid'] = '***********'; //申请商户号的appid或商户号绑定的appid$param['mchid'] = '***********'; //商户id$param['device_info'] = ""; //设备号，可空值$param['nonce_str'] = Zmd5(time() . Zrand(5) . 'test'); //随机字符串$param['partner_trade_no'] = $withdrawInfo['tid']; //内部订单号$param['openid'] = $userInfo['open_id']; //提现用户的open_id$param['check_name'] = "NO_CHECK"; //不校验用户姓名$param['re_user_name'] = '';$param['amount'] = "" . $withdrawInfo['real_price'] * 100; //提现金额，单位是分故乘100$param['desc'] = "佣金提现"; //提现描述$param['spbill_create_ip'] = request()->ip(); //客户端ip或服务端ip均可//处理签名（签名规则末尾有官方文档链接，此处不介绍）ksort($param);$string = ToUrlParams($param);$string = $string .
