微信公众号 企业付款 微信用户(商户号,微信公众号:appid,openid)demo

流程:

微信用户从微信公众号进入查询页面(网页授权获取openid),进行提交申请单。
后台管理员进行审核(支付,驳回),主要记录支付操作。

事先准备:

    1、商户号
    2、公众号(开通支付功能)
    3、商户号绑定到公众号
    4、证书(由商户号进行生成导出,用于api验证)https://kf.qq.com/faq/180824BrQnQB180824m6v2yA.html

主要操作:主要两个动作(获取openid,付款)**

一、 获取用户openid,并记录。(时间,申请金额什么的乱七八糟的参数略略略略)

    可由公众号会话生成(未用)
    网页授权生成(因为有页面用此方法)
    1、请求连接(https://open.weixin.qq.com/connect/oauth2/authorize?appid=*************d&redirect_uri=(回传地址)jump.php&response_type=code&scope=snsapi_base&state=1#wechat_redirect)
    由中转页获取code并请求获取用户openid

jump.php

二、 付款(用到之前准备项)

官方:https://pay.weixin.qq.com/wiki/doc/api/tools/mch_pay.php?chapter=14_2

1、请求参数(简化过了,针对不同进行需求修改)

 //支付rpc
$this->wx_pay_client = new xmlrpc_client('http:/*********_server.php', 'app_com');
....
$pay_id = time() . rand(1000, 9999);
$money = $log_data['money'];
$arr = array(
   'appid' => 'w*****d',//公众号appid
   'partner_trade_no' => $pay_id,//商户订单号(标准见官方文档)
   'openid' => $open_id,//接收人openid
   'amount' => $money * 100,//单位分
    'desc' => '微信提现',//描述
);
$rs = $this->wx_pay_client->call('transfers', $arr);//封装过的支付rpc
if ($rs['result_code'] != 'SUCCESS') {
    $arr = array(
         'ret' => 0,
          'msg' => $rs['return_msg']
    );
}else{
 
}
