出現錯誤：
伺服器報錯500
返回資訊：no SOAPAction header!
<?xml version="1.0" encoding="utf-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

解決方案：在請求端，加上一個請求頭
openConnection.setRequestProperty("SOAPAction", "\"\"");或者
openConnection.setRequestProperty("SOAPAction", "");
