但是試過 Ksoap2 後發現它包出來的格式和WSDL的格式無法符合，讓server 無法解析。在<soapenv:Envelope>中無法自訂自己的namespace資訊。所以只能自己動手包出request，以下詳細說明各段所需程式碼。
基本所需的變數
private final String MAIN_REQUEST_URL = "http://tmpuri.org/"; private final String NAMESPACE = "http://namespaceuri.org/"; private String SOAP_ACTION = "http://namespaceurimethod.org/"; private HttpURLConnection SERVER_CONNECTION;
此request範例是我遇到的 WSDL server內定的格式，所以可能會跟別人遇到的有點誤差，自行調整
request範例
String requestString = "<Request>"+
"<Access/>"+
"<RequestContent>"+
"<Parameter>"+
"<Record>"+
"<Field name=\"user\" value=\"hello\" />"+
"<Field name=\"pwd\" value=\"abc1234\" />"+
"</Record>"+
"</Parameter>"+
"<Document />"+
"</RequestContent>"+
"</Request>";
String actionName = "CheckLogin";
包出SOAP格式
public String getSoapEnvelope(String actionName, String requestString) {
SOAP_ACTION += actionName;
String soapEnvelope = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:sv=\""+NAMESPACE+"\">" +
"<soapenv:Header/>" +
"<soapenv:Body>";
soapEnvelope += " <tip:"+actionName+"><sv:request>";
//add request
soapEnvelope += requestString;
soapEnvelope += "</sv:request></sv:"+actionName+">";
soapEnvelope += "</soapenv:Body></soapenv:Envelope>";
return soapEnvelope;
}
包出soap envolope後，就可以把這個字串透過http request傳送給server
建立http request
public String sendRequestToSystem(String soapEnvelope) {
BufferedReader rd = null;
String line;
String resultXML = "";
try {
//create connection
URL url = new URL(MAIN_REQUEST_URL);
HttpURLConnection soapServerConnection = (HttpURLConnection) url.openConnection();
soapServerConnection.setDoOutput(true);
soapServerConnection.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
soapServerConnection.setRequestProperty("SOAPAction", SOAP_ACTION);
soapServerConnection.setRequestProperty("POST", MAIN_REQUEST_URL+" HTTP/1.1");
soapServerConnection.setRequestProperty("Content-Length", "" + soapEnvelope.length());
soapServerConnection.setRequestProperty("Accept-Encoding", "gzip,deflate");
soapServerConnection.setRequestMethod("POST");
byte[] postData = soapEnvelope.getBytes();
//send data to soap server
DataOutputStream wr = new DataOutputStream(this.soapServerConnection.getOutputStream());
wr.write(postData);
wr.close();
//read data from soap server
BufferedReader rd = new BufferedReader(new java.io.InputStreamReader(soapServerConnection.getInputStream()));
while ((line = rd.readLine()) != null) {
line = line.replace("<", "<");
line = line.replace(">", ">");
resultXML += line;
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (ProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return resultXML;
}
依照上述流程透過 resultXML變數就可以取得 soap response資訊
推薦一個測試WSDL的工具: SOAP UI
可以建立一個WSDL的project連線到server 測試每個request 很方便.
