                                            这段代码中，我想要得到out_trade_no，怎么取

Answer 1

其实配合JSON来做就很简单了，先通过

        String aa =你的字符串;
        aa = aa.replace("alipay_trade_app_pay_response:", "");
        JSONObject data = JSON.parseObject(aa);
        String bb=data.getString("out_trade_no");

这里用到的是fastjson
