php调用java开发的webservice接口报soap:Server: Fault occurred while processing

请求的数据

Array ( [sTicket] => {"username":"3ab6e844ca851bf318294a4f30f4a03e","password":"449924A9471E628995E503E34E9F5C88"} [sMGoods] => {"goodsguid":"60698","goodssourceurl":"http://www.city-office.com.cn/goods.php?id=60698"} )

php调用接口引用nusoap类 用$client->call()方法

上一个接口用同样的方法访问可以 到这个方法就不行了为什么

require_once('lib/nusoap.php'); $client = new nusoap_client('http://220.191.208.229/gpmall/ws/MallService?wsdl', 'wsdl','',''); $client->soap_defencoding = 'utf-8'; $client->xml_encoding = 'utf-8'; $client->decode_utf8 = false; $username = '3ab6e844ca851bf318294a4f30f4a03e'; $pwd = '449924A9471E628995E503E34E9F5C88'; $aa1= array('username'=>$username, 'password'=>$pwd); $aa1=json_encode($aa1); //print_r($aa1); $goodsparams=array('goodsguid'=>'60698', 'goodssourceurl'=>'http://www.city-office.com.cn/goods.php?id=60698', ); $goodsparams=json_encode($goodsparams); //print_r($goodsparams); $arr=array('sTicket'=>"$aa1",'sMGoods'=>"$goodsparams"); print_r($arr); $result = $client->call('exchangeGoodsURL',$arr, '', '', false, true); if (!$err=$client->geterror()) { //echo '已交换'; print_r($result); echo '
'; } else { echo 'no'; if ($err) { // Display the error echo '
Error
' . $err . '
'; } else { //print_r($result); //echo $result['out']; $ts=explode(',',$result['out']); $ts1=explode(':',$ts[1]); echo $i+1,":",$ts1[1],"
" ; } }
