When Android, iOS app calls WeChat payment, the page appears blank. (PHP WeChat payment, app launched WeChat payment white screen)?

The page appears blank when you make an Android or iOS app call
My backend was developed in PHP. I am the first to call the unified next order generation, generate prepay_id pre-paid order number, the code is as follows:

  config[' money ') *100; $notify _url= $this->config[' Notifyurl ']; Notification url//set the unified Payment interface parameters//settings required parameters//appid filled, the merchant does not need to fill in the//mch_id, the merchant does not need to fill in the//noncestr, the merchant does not need to fill in the//spbill_create_ip is filled, The merchant does not need to fill in the//sign, the merchant does not need to fill in the//iconv ("gb2312", "Utf-8//ignore", $unifiedOrder->setparameter ("Body", $this, config[' title ');//Commodity Description//Custom order number, here only for example $out_trade_no = $this->config[' code ']; $create _ip = $_server["REMOTE_ADDR" ]; $unifiedOrder->setparameter ("Out_trade_no", $out _trade_no);//Merchant Order number $unifiedOrder->setparameter ("Total_ Fee ", $amount);//Total Amount $unifiedorder->setparameter (" Notify_url ", $notify _url);//Notification address $unifiedOrder Setparameter ("Spbill_create_ip", $create _ip);//user-side actual ip$unifiedorder->setparameter ("Trade_type", "APP");// App Trading type $unifiedorder->setparameter ("Attach", "111");//Append Data//Get Unified Payment Interface Result $unifiedorderresult = $unifiedOrder GetResult ();//Merchant according to the actual situation to set the corresponding processing process if ($unifiedOrderResult ["return_code"] = = "FAIL") {//merchant to increase the processing process echo "Communication error:". $unifie dorderresult[' return_msg '].

Send the following parameters to Android and iOS:

$result['appid'] = $unifiedOrderResult['appid'];$result['partnerid'] = $unifiedOrderResult['mch_id'];$result['prepayid'] = $unifiedOrderResult['prepay_id'];$result['noncestr'] = $unifiedOrderResult['nonce_str'];$result['timestamp'] = time();$result['package'] = "Sign=WXPay"; //'Sign=WXPay'$result['sign'] = $unifiedOrderResult['sign'];

However, Android, iOS over the call to pay when actually show blank, what error prompt is not, as follows:

When the above transaction class is changed to sweep code payment, the generated QR code can be paid successfully.
has been for one weeks, the card here has been unable to move, ask God to help see, this is what problem, thank you very much
