支付宝支付接口(即时到账交易接口)

时间:2022-01-09 03:21:02
create_direct_pay_by_user 官方参数API文档地址:

步骤:
  • 1. 按照官方文档,编写此接口所需要的各个参数;
  • 2. 对各参数进行签名处理,生成URL;
  • 3.调用此URL,跳转到支付宝官方扫码支付页面;
  • 4.支付成功后会进行回调通知,通知自己系统已经支付

一.访问参数:

支付宝支付接口(即时到账交易接口)


二.回调参数

array(22) {
["body"]=>//商品描述
string(18) "690525226950818654"
["buyer_email"]=>
string(16) "11111@qq.com"

string(4) "0.01"//交易金额,单位是元
["trade_no"]=>
string(28) "2016082321001004270244845496",//支付宝生成的
["trade_status"]=>
string(13) "TRADE_SUCCESS"//交易结果
["sign"]=>
string(32) "1e85b163affcaab205767ec8585d64cd"//签名
["sign_type"]=>
string(3) "MD5"
}


记得在自己回调方法的逻辑里添加合法性验证


三. 注意:

1.需要特别提醒的两个参数:

return_url:同步页面回调地址,可以配置HOST在本地调试(扫码成功以后,会在扫码页面 带回调参数跳转回此URL,进行后续操作)
notify_url: 异步回调通知地址,只能在服务器调试 (扫码成功以后,支付宝系统带回调参数异步访问此URL,进行后续操作)

2.回调时记得进行合法性验证(详细代码见下方)
