扫微信接口生成的2微码图片但是发现后台接收不到请求!

用 ticket 生成了一张永久带参数的2微码图片，根据接口里面说明如果已关注并且在扫这张2微码图片的话会发送相应请求到开发者配置的后台，但是怎么尝试都接收不到请求，各位大神有遇到此类问题吗。
根据API上说 只要跟微信产生会话就可以立马获取此人的物理地址这个接口，貌似也获取不到请求。
我拥有高级权限！求解。
不能回答已答过的问题、已关闭的问题和你自己的提问1个回答
没有。。用的很正常。是不是回调的问题？

(160 积分)微信扫码支付，模式二方式开发
&此文仅仅针对微信扫码支付方式；
方法一assembleOrder 用来拼装相关参数 &其中ScanPayReqData& 参见先关微信扫码支付demo &或者参见后面有该类
public ThirdOrderRequest assembleOrder(Order order) {
WXMerchant merchant = new WXMerchant();
ScanPayReqData reqData = new ScanPayReqData();
reqData.setAppid(merchant.appid);
//公众账号ID wx***********ae33e (位数相同已*代替)
reqData.setMch_id(merchant.mchid);
1*******02
reqData.setNonce_str(RandomStringGenerator.getRandomStringByLength(32));
reqData.setBody( order.productName);
reqData.setOut_trade_no(order.orderId); //订单
reqData.setTotal_fee(order.total_fee);
reqData.setFee_type(&CNY&);
reqData.setSpbill_create_ip(order.ip);
reqData.setNotify_url(merchant.payNotifyUrl);
//回调地址
SimpleDateFormat sdf = new SimpleDateFormat(&yyyyMMddHHmmss&);
String time_start= sdf.format(System.currentTimeMillis()+24*60*60*1000);
// reqData.setTime_start(time_start);
reqData.setTrade_type(merchant.tradeType); //交易类型
reqData.setProduct_id(order.productId);//产品ID
String sign = WXPayHelper.getSign(reqData.toMap(),merchant.appSecret); //见方法二
reqData.setSign(sign);//把签名数据设置到Sign这个属性中
return new ThirdOrderRequest(reqData);
方法二&&WXPayHelper.getSign sign签名生成方法。其中key 为应用秘钥 如jia************************tvgd（获取于微信平台）
public static String getSign(Map map,String key){
ArrayList list = new ArrayList();
for(Map.Entry entry:map.entrySet()){
if(entry.getValue()!=&& && !entry.getKey().equals(&sign&)){
list.add(entry.getKey() + &=& + entry.getValue() + &&&);
int size = list.size();
String [] arrayToSort = list.toArray(new String[size]);
Arrays.sort(arrayToSort, String.CASE_INSENSITIVE_ORDER);
StringBuilder sb = new StringBuilder();
for(int i = 0; i & i ++) {
sb.append(arrayToSort[i]);
String result = sb.toString();
result += &key=& +
//Util.log(&Sign Before :& + result);
result = MD5.MD5Encode(result).toUpperCase();
//Util.log(&Sign Result:& + result);
方法三 获取支付所需扫码二维码方法
public String submitOrder(ThirdOrderRequest order) {
WXMerchant merchant = new WXMerchant();
String url = &https://api.mch./pay/unifiedorder&;//微信下单获取二维码接口url
//得到数据
ScanPayReqData scanPayReqData = (ScanPayReqData) order.getData();//获取到接口一的ScanPayReqData
自行修改。
WXPAYClient wxpayClient = new WXPAYClient();//微信扫码client
String respXML =wxpayClient.sendPost(url, scanPayReqData);//返回xml类型
System.out.println(&respXML====&+respXML);
ScanPayResData scanPayResData = (ScanPayResData) WXPayHelper.getObjectFromXML(respXML, ScanPayResData.class);//xml转对象
//防止数据被恶意篡改
String return_code = scanPayResData.getReturn_code();
String result_code =
scanPayResData.getResult_code();
String sign = WXPayHelper.getSign(WXPayHelper.toMap(scanPayResData),merchant.appSecret);
//通讯不成功直接返回
if(!TRADE_TRADE_STATUS.equals(return_code)) {
scanPayResData.getReturn_msg();
//业务不成功同样直接返回业务错误代码
if(!TRADE_TRADE_STATUS.equals(result_code)){
return scanPayResData.getErr_code();
if(sign.equals(scanPayResData.getSign())){//安全验证。
//返回code url
String picUrl = getQRImageUrl(scanPayResData.getCode_url());
return &sign验签不正确&;
} catch (Exception e) {
e.printStackTrace();
return &&;
