PHP使用curl_init post 提交json 或 SoapClient 外部服务器报错

使用curl_init:

$serviceURL = 'http://61.153.225.106:5678/Service.asmx/tests';
 $ch = curl_init ( $serviceURL );
 curl_setopt ( $ch, CURLOPT_CUSTOMREQUEST, "POST" );
 curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, true );
 curl_setopt ( $ch, CURLOPT_POSTFIELDS, $strjson ); //全部数据使用HTTP协议的POST操作来发送
curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, false );
 curl_setopt ( $ch, CURLOPT_SSL_VERIFYHOST, false );
 curl_setopt ( $ch, CURLOPT_HTTPHEADER, array (
 'Content-Type: application/json; charset=utf-8;',
 'Content-Length: ' . strlen ( $strjson )
 ) );
 curl_setopt($ch,CURLOPT_POST,1);
 $result = curl_exec ( $ch );
 $errorNo = curl_errno ( $ch );
 echo $errorNo; //错误号 输出0
 echo "error:".curl_error($ch);
 echo $result; //执行信息 报错
curl_close ( $ch );

json字符串：{"ccode":"1234ew4" , "ddate":"2015-12-16", "ccuscode":"0100001", "cinvcode":"100101", "iquantity":"1", "address":"测试地址", "cmemo":"无", "cmaker":"demo", "cverifer":"demo", "dpredate":"2015-12-17", "imoney":"1"}

其中ccode是需要变化的，同一个插入不进去。由于是往第三方插入数据，所以没法改变上
