通过付款条形码区分支付渠道，比如微信、支付宝或者银联：
public static String getPayChannel(String authCode) {
String payChannel;
String wx[] = { "10", "11", "12", "13", "14", "15" };
String ali[] = { "25", "26", "27", "28", "29", "30" };
if (StringUtils.startsWithAny(authCode.substring(0, 2), wx)) {
payChannel= "wx";
} else if (StringUtils.startsWithAny(authCode.substring(0, 2), ali)) {
payChannel= "ali";
}else {
payChannel= "upop";
}
return payChannel;
}
