最近我开始研究在黑莓中使用 wcf rest webservices。
我使用了以下两个代码：
1. URLEncodedPostData postData = new URLEncodedPostData(URLEncodedPostData.DEFAULT_CHARSET, false); // 传递 q 的值和 ie 的值
postData.append("UserName", "hsharma@seasiaconsulting.com");
postData.append("Password", "mind@123");
HttpPosst hh=new HttpPosst();
add(new LabelField("1"));
String res=hh.GetResponse("http://dotnetstg.seasiaconsulting.com/profire/ProfireService.svc/UserRegistration",postData);
add(new LabelField("2"));
add(new LabelField(res));
公共字符串 GetResponse（字符串 url，URLEncodedPostData 数据）{
this._postData = data;
this._url = url;
ConnectionFactory conFactory = new ConnectionFactory();
ConnectionDescriptor conDesc = null;
try
{
if (WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED)
{
connectionString = ";interface=wifi";
}
// Is the carrier network the only way to connect?
else if ((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_DIRECT) == CoverageInfo.COVERAGE_DIRECT) {
// logMessage("Carrier coverage.");
// String carrierUid = getCarrierBIBSUid();
// Has carrier coverage, but not BIBS. So use the carrier's TCP
// network
// logMessage("No Uid");
connectionString = ";deviceside=true";
}
// Check for an MDS connection instead (BlackBerry Enterprise
// Server)
else if ((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_MDS) == CoverageInfo.COVERAGE_MDS) {
// logMessage("MDS coverage found");
connectionString = ";deviceside=false";
}
// If there is no connection available abort to avoid bugging the
// user
// unnecssarily.
else if (CoverageInfo.getCoverageStatus() == CoverageInfo.COVERAGE_NONE)
{
// logMessage("There is no available connection.");
}
// In theory, all bases are covered so this shouldn't be reachable.
else {
// logMessage("no other options found, assuming device.");
// connectionString = ";deviceside=true";
}
conDesc = conFactory.getConnection(url + connectionString);
}
catch (Exception e)
{
System.out.println(e.toString() + ":" + e.getMessage());
}
String response = ""; // this variable used for the server response
// if we can get the connection descriptor from ConnectionFactory
if (null != conDesc)
{
try
{
HttpConnection connection = (HttpConnection) conDesc.getConnection();
// set the header property
connection.setRequestMethod(HttpConnection.POST);
connection.setRequestProperty("Content-Length",Integer.toString(data.size()));
// body content of
// post data
connection.setRequestProperty("Connection", "close");
// close
// the
// connection
// after
// success
// sending
// request
// and
// receiving
// response
// from
// the
// server
connection.setRequestProperty("Content-Type","application/json");
// we set the
// content of
// this request
// as
// application/x-www-form-urlencoded,
// because the
// post data is
// encoded as
// form-urlencoded(if
// you print the
// post data
// string, it
// will be like
// this ->
// q=remoQte&ie=UTF-8).
// now it is time to write the post data into OutputStream
OutputStream out = connection.openOutputStream();
out.write(data.getBytes());
out.flush();
out.close();
int responseCode = connection.getResponseCode();
// when this
// code is
// called,
// the post
// data
// request
// will be
// send to
// server,
// and after
// that we
// can read
// the
// response
// from the
// server if
// the
// response
// code is
// 200 (HTTP
// OK).
if (responseCode == HttpConnection.HTTP_OK)
{
// read the response from the server, if the response is
// ascii character, you can use this following code,
// otherwise, you must use array of byte instead of String
InputStream in = connection.openInputStream();
StringBuffer buf = new StringBuffer();
int read = -1;
while ((read = in.read()) != -1)
buf.append((char) read);
response = buf.toString();
}
// don’t forget to close the connection
connection.close();
}
catch (Exception e)
{
System.out.println(e.toString() + ":" + e.getMessage());
}
}
return response;
}
public boolean checkResponse(String res)
{
if(!res.equals(""))
{
if(res.charAt(0)=='{')
{
return true;
}
else
{
return false;
}
}
else
{
return false;
}
}
但是使用此代码，我无法获得上述 wcf Web 服务返回的响应，即 ({"UserRegistrationResult":[{"OutputCode":"2","OutputDescription":"UserName Already Exists."}]})
任何人都可以帮我解决它在黑莓客户端中的解析。
2.我使用的另一个代码是：
公共类 KSoapDemo 扩展 MainScreen {
private EditField userNametxt;
private PasswordEditField passwordTxt;
private ButtonField loginBtn;
String Username;
String Password;
public KSoapDemo()
{
userNametxt = new EditField("User Name : ", "hsharma@seasiaconsulting.com");
passwordTxt = new PasswordEditField("Password : ", "mind@123");
loginBtn = new ButtonField("Login");
add(userNametxt);
add(passwordTxt);
add(loginBtn);
loginBtn.setChangeListener(new FieldChangeListener()
{
public void fieldChanged(Field field, int context)
{
//Dialog.alert("Hi Satyaseshu..!");
login();
}
});
}
private void login()
{
if (userNametxt.getTextLength() == 0 || passwordTxt.getTextLength() == 0)
{
//Dialog.alert("You must enter a username and password", );
}
else
{
String username = userNametxt.getText();
String password = passwordTxt.getText();
System.out.println("UserName... " + username);
System.out.println("Password... " + password);
boolean value = loginPArse1(username, password);
add(new LabelField("value... " + value));
}
}
public boolean onClose()
{
Dialog.alert("ADIOOO!!");
System.exit(0);
return true;
}
public boolean loginPArse1(String username, String password)
{
username=this.Username;
password=this.Password;
boolean ans = false;
String result = null;
SoapObject request = new SoapObject("http://dotnetstg.seasiaconsulting.com/","UserRegistration");
//request.addProperty("PowerValue","1000");
//request.addProperty("fromPowerUnit","kilowatts");
//request.addProperty("toPowerUnit","megawatts");
request.addProperty("userName",Username);
request.addProperty("Password", Password);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.bodyOut = request;
envelope.dotNet = true;
add(new LabelField("value... " + "1"));
HttpTransport ht = new HttpTransport("http://dotnetstg.seasiaconsulting.com/profire/ProfireService.svc/UserRegistration"+ConnectionInfo.getInstance().getConnectionParameters());
ht.debug = true;
add(new LabelField("value... " + "2"));
//System.out.println("connectionType is: " + connectionType);
try {
ht.call("http://dotnetstg.seasiaconsulting.com/profire/ProfireService.svc/UserRegistration", envelope);
SoapObject body = (SoapObject) envelope.bodyIn;
add(new LabelField("soap....="+body.toString()));
add(new LabelField("property count....="+body.getPropertyCount()));
// add(new LabelField("Result....="+body.getProperty("HelloWorldResult")));
//result = body.getProperty("Params").toString();
// add(new LabelField("value... " + "4"));
ans=true;
}
catch (XmlPullParserException ex) {
add(new LabelField("ex1 "+ex.toString()) );
ex.printStackTrace();
} catch (IOException ex) {
add(new LabelField("ex1 "+ex.toString()) );
ex.printStackTrace();
} catch (Exception ex) {
add(new LabelField("ex1 "+ex.toString()) );
ex.printStackTrace();
}
return ans;
}
作为回报，我得到响应为 net.rim.device.cldc.io.dns.DNS Exception:DNS Error
请在这方面帮助我
