企業付款的應用情境: 公眾號向已關注用戶付款,例如處理退款、財務結算等,本文主要和大家分享php開發微信支付企業付款實例代碼,希望能幫助大家。
1.憑證需要用自己的商家裡面的憑證(注意:憑證路徑必須是絕對路徑,如果使用相對路徑會回報下面的錯誤。
unable to use client certificate (no key found or wrong pass phrase?)
2.appid,secret以及key填寫自己的即可。想法:
1.首先取得openid,具體方法見下面。
#參數參考: 企業付款API的文件1.取得CODE(index.php頁面)/** * API 参数 * @var array * ‘mch_appid’ # 公众号APPID * ‘mchid’ # 商户号 * ‘device_info’ # 设备号 * ‘nonce_str’ # 随机字符串 * ‘partner_trade_no’ # 商户订单号 * ‘openid’ # 收款用户openid * ‘check_name’ # 校验用户姓名选项 针对实名认证的用户 * ‘re_user_name’ # 收款用户姓名 * ‘amount’ # 付款金额 * ‘desc’ # 企业付款描述信息 * ‘spbill_create_ip’ # Ip地址 * ‘sign’ # 签名 */2.資訊回呼頁碼處理(getInfo.php)
3.產生簽章函數檔(api.php)<?php //信息回调文件所在的服务器位置$str="http://www.xxx.com/company_pay/getInfo.php";$str_url=urlencode($str);$appid = "xxxx3e5273505e";$url = 'https://open.weixin.qq.com/connect/oauth2/authorize?appid='.$appid.'&redirect_uri='.$str_url.'&response_type=code&scope=snsapi_userinfo&state=STATE#wechat_redirect'; header("Location:".$url);?>
