支付结果接收接口，接收到如下数据，请问怎么提取

Question

在对接某聚合支付时候，支付结果对方以post形式返回到我的服务器

通过打印得到post数据如下：
'_POST' =>
array (
'{"interfaceType":"2","memberCode":"1010000873","orderNum":"1841503477441840955","payMoney":"2_00","payNum":"20170823163726423137","payTime":"20170823163735","payType":"2","platformType":"3","respType":"2","resultCode":"0000","resultMsg":"浜ゆ槗鎴愬姛","signStr":"wiTuiG4lWOYVW/qKjJXWzY8Kt7zLDpufRqJCiuazt8AykrviD2Y_1QlIoDlttm5/6a6gmBhdCgATUc6TOGwcXQ' => '="}',
),

所有有效数据都是在array的键名中。请问怎么提取

 <br> <br> <br> <br>

"signStr":"wiTuiG4lWOYVW/qKjJXWzY8Kt7zLDpufRqJCiuazt8AykrviD2Y_1QlIoDlttm5/6a6gmBhdCgATUc6TOGwcXQ' => '="}',

问题根源

其实signStr 的值是
wiTuiG4lWOYVW/qKjJXWzY8Kt7zLDpufRqJCiuazt8AykrviD2Y_1QlIoDlttm5/6a6gmBhdCgATUc6TOGwcXQ==

不清楚为什么尾部变成6TOGwcXQ' => '="}',

Answer 1

这个具体要看你和支付接口之间的关系，最好说一下支付方式是哪一种 查查文档，不难的
