我目前正在使用
@L_502_0@研究SOAP消息格式到Socket Message格式转换,反之亦然.
我需要这个来重用读取套接字格式消息的遗留系统来连接到发送和接收SOAP消息格式的网站.
我该怎么做？我应该考虑文字处理吗？
示例Socket到SOAP
插座
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Interface Code="20"
<Transaction Txn="01880120121024000001" CD="01880120121024000001001"
Date="2012-10-24 17:27:25" BirthDate="1983-03-27" Code="8110009000000720" Type="0"/>
</Interface>
肥皂
<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<webRequest xmlns="http://____________">
<arg0 xmlns=""><?xml version="1.0" encoding="UTF-8"
standalone="yes"?><Interface xmlns="http://____________"
Version="1.0" Code="20" Txn="123" CD="456"><Info
BirthDate="1983-03-27" Code="1234" Type="0" /></Interface></arg0>
</webRequest>
</soapenv:Body>
</soapenv:Envelope>
解决方法
套接字消息是SOAP消息的XML转义主体.您不需要额外的库,因为有
parsing SOAP requests的javax类.
SOAP到socket非常简单：
String message = "<?xml version='1.0' encoding='UTF-8'?>\n<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\">\n <soapenv:Body>\n <webRequest xmlns=\"http://____________\">\n <arg0 xmlns=\"\"><?xml version=\"1.0\" encoding=\"UTF-8\"\n standalone=\"yes\"?><Interface xmlns=\"http://____________\"\n Version=\"1.0\" Code=\"20\" Txn=\"123\" CD=\"456\"><Info\n BirthDate=\"1983-03-27\" Code=\"1234\" Type=\"0\" /></Interface></arg0>\n </webRequest>\n </soapenv:Body>\n</soapenv:Envelope>"; InputStream is = new ByteArrayInputStream(message.getBytes()); SOAPMessage request = MessageFactory.newInstance().createMessage(null,is); System.out.println(request.getSOAPBody().getTextContent());
Socket to SOAP更复杂,因为我们需要创建webRequest包装元素：
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
docFactory.setNamespaceAware(true); // webRequest needs a namespace
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.newDocument();
Element root = doc.createElementNS("http://____________","webRequest");
doc.appendChild(root);
Element argElement = doc.createElement("arg0");
root.appendChild(argElement);
String message = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>\n<Interface Code=\"20\" \n <Transaction Txn=\"01880120121024000001\" CD=\"01880120121024000001001\" \n Date=\"2012-10-24 17:27:25\" BirthDate=\"1983-03-27\" Code=\"8110009000000720\" Type=\"0\"/>\n</Interface>";
argElement.setTextContent(message);
SOAPMessage request = MessageFactory.newInstance().createMessage();
request.getSOAPBody().addDocument(doc);
request.setProperty(SOAPMessage.WRITE_XML_DECLARATION,"true");
request.writeTo(System.out);
