I am having an issue with sending a jagged Array to a wcf webservice. The method is expecting a studentId and jaggedArray of information related to the student. Here is the method signature in c#
String[][] SearchStudent(string studentId, String[][] additionalInformation);
According to KSOAP wiki page, the below piece of code should have worked. I've also tried it with Hashtable; it returned the same error message.
SoapObject additionalInformation = new SoapObject(NAMESPACE, "SearchStudent");
additionalInformation.addProperty("StudentFirstName", "John");
additionalInformation.addProperty("StudentLastName", "Doe
additionalInformation.addProperty("StudentDOB", "06101990");
SoapObject request = new SoapObject(NAMESPACE, "Authenticate");
request.addProperty("sessionId", params[0]);
request.addProperty("additionalInformation ", AuthParams);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.bodyOut = request;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(url);
androidHttpTransport.debug = true;
(new MarshalHashtable()).register(envelope);
androidHttpTransport.call(SOAP_ACTION + "SearchStudent", envelope);
SoapObject sResult = (SoapObject)envelope.getResponse();
I am getting the message Invalid argument error message.
What am I doing wrong here?
I was able to get it to work with envelope.version 10 and not 11. Here is the link to my other post where you can find the solution.

I am newbie to web service. Due to requirement I have to send a file[most probably in txt format] to server through REST web service.
I am getting the exception like below.
MessageBodyWriter not found for media type=application/json, type=class gvjava.org.json.JSONObject, genericType=class gvjava.org.json.JSONObject.
Here is my web service method.
#Path("{c}")
#POST
#Produces(MediaType.APPLICATION_JSON)
#Consumes(MediaType.APPLICATION_JSON)
public String convert(#PathParam("c") JSONObject object) throws JSONException {
String result = "";
return "<ctofservice>" + "<ctofoutput>" + result + "</ctofoutput>" + "</ctofservice>";
}
Now client code is like below
JSONObject data_file = new JSONObject();
data_file.put("file_name", uploadFile.getName());
data_file.put("description", "Something about my file....");
data_file.put("file", uploadFile);
Client client = ClientBuilder.newClient();
webTarget = client.target(uploadURL).path("ctofservice").path("convert");
Response value = webTarget.request(MediaType.APPLICATION_JSON_TYPE)
.post(Entity.entity(data_file,MediaType.APPLICATION_JSON_TYPE),
Response.class);
Please help me with this.
Thanks in advance.

As suggested by peeskillet in the answer below, I tried to send file through multipart. Still I am facing exception of no octet stream found.
Below is my rest api
#Path("{c}")
#POST
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response convert(#FormDataParam("file") FormDataContentDisposition file) {
String result = "";
Some operation with attached parameter ...
return Response.status(200).entity(result).build();
}
Here is my test client
FormDataMultiPart multiPart = new FormDataMultiPart();
multiPart.setMediaType(MediaType.MULTIPART_FORM_DATA_TYPE);
FileDataBodyPart fileDataBodyPart = new FileDataBodyPart("file",
uploadFile,MediaType.APPLICATION_OCTET_STREAM_TYPE);
multiPart.bodyPart(fileDataBodyPart);
Client client = Client.create();
WebResource webResource = client
.resource(uploadURL).path("ctofservice");
ClientResponse response = webResource.accept("application/json")
.post(ClientResponse.class,multiPart);
if (response.getStatus() != 200) {
throw new RuntimeException("Failed : HTTP error code : "
+ response.getStatus());
}
And I am getting the exception below
I am not able to understand why I need to send data as MediaType.APPLICATION_OCTET_STREAM_TYPE ? As I have used multipart as media type before ...
I appreciate your help..
Without needing to configuring anything else, the easiest way to get around this is to just use a String instead of the actual JSONObject (i.e. just passing toString())
.post(Entity.json(data_file.toString()))
The problem with using JSONObject is that there is no provider that knows how to handle the conversion. You will have the same problem on the server side, where there is no provider to handle the conversion to JSONObject. So you will need to just do
#POST
public Response post(String json) {
JSONObject jsonObject = new JSONObject(json);
}
If you really want to be able to just use JSONObject without needing to use a String, then you should check out this post.
As an aside, this is not valid JSON (it's XML)
"<ctofservice>" + "<ctofoutput>" + result + "</ctofoutput>" + "</ctofservice>"
but you are saying that the endpoint returns JSON
I perform a POST using Robospice and okHttp :
public String loadDataFromNetwork() throws Exception {
uriBuilder = Uri.parse(url).buildUpon();
uri = new URI(uriBuilder.build().toString());
tmp = "user=" + user + "&password=" + pwd
HttpURLConnection connect = new OkUrlFactory(client).open(uri.toURL());
// Send post request
connect.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(connect.getOutputStream());
wr.writeBytes(tmp);
wr.flush();
wr.close();
// Read the response
in = connect.getInputStream();
}
Is there a better way to send a post (with Robospice/okHttp) ?
NB : my code is working fine, just want to know if it's correct or not...
The problem is that if I want to use the okHttp POST like that :
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url("https://api.github.com/markdown/raw")
.post(RequestBody.create(MEDIA_TYPE_MARKDOWN, parameters))
.build();
Response response = client.newCall(request).execute();
if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
System.out.println(response.body().string());
with Robospice, RequestBody and newCall and isSuccessful cannot be resolved !
Do I have a solution to use okHttp post WITH Robospice ? (I know how to make a GET, but not a POST...)
I am accessing Rackspace Cloud APIs.
I have one api call which authenticates me on the rackspace cloud.
The method works perfectly, however, from time to time, i get this exception, randomly :
The remote name could not be resolved: 'identity.api.rackspacecloud.com'
When i am not getting this exception, the method returns the expected result, as it should be.
Is there any specific reason why it does this?
Here is my .net code:
private async Task<XDocument> AuthenticateAsync()
{
XNamespace ns = "http://docs.rackspace.com/identity/api/ext/RAX-KSKEY/v1.0";
XDocument doc =
new XDocument(
new XDeclaration("1.0", "UTF-8", "Yes"),
new XElement("auth",
new XElement(ns + "apiKeyCredentials",
new XAttribute("username", "the userName"),
new XAttribute("apiKey", "the apiKey")
)
)
);
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));
StringContent content = new StringContent(doc.ToString(), Encoding.UTF8, "application/xml");
// i randomly get "The remote name could not be resolved" exception
HttpResponseMessage response = await client.PostAsync("https://identity.api.rackspacecloud.com/v2.0/tokens", content);
response.EnsureSuccessStatusCode();
string stringResponse = await response.Content.ReadAsStringAsync();
return XDocument.Parse(stringResponse);
}
}
This certainly sounds like a DNS failure. Can you configure your machine to use the Google DNS servers and try again?
I'm working on a WinRT app that does login to a webpage and get some data. The problem is that I'm getting a "HttpRequestException: An error occurred while sending the request" message. Here is the code:
Uri url = new Uri("https://miyoigo-b.yoigo.com/selfcare/login");
HttpContent msg = new StringContent("account[cli]=" + number + "&password=" + pass);
HttpClientHandler handler = new HttpClientHandler();
handler.UseDefaultCredentials = true;
handler.UseCookies = true;
handler.CookieContainer = new CookieContainer();
HttpClient req = new HttpClient(handler);
req.DefaultRequestHeaders.Add("Host", "miyoigo-b.yoigo.com");
req.DefaultRequestHeaders.ExpectContinue = false;
HttpResponseMessage response = await req.PostAsync(url, msg);
string responseBody = await response.Content.ReadAsStringAsync();
I've been trying a lot of thing I found over the internet, even disabling my firewall, but nothing worked. I'm porting this from a Windows Phone app and it did work with this:
Uri url = new Uri("https://miyoigo-b.yoigo.com/selfcare/login");
HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(url);
req.Method = "POST";
req.Headers["Host"] = "miyoigo-b.yoigo.com";
req.CookieContainer = new CookieContainer();
req.BeginGetRequestStream(new AsyncCallback(WriteCallback), req);
And afterwards, in the Callback I created a Stream and wrote the credentials.
Any idea?? I know that the problem is only with this webpage, maybe I'm forgetting to send something or the format of the POST content is not correct...
Thanks
Finally the problema was that Win8 Metro Apps only accepts SSL3.1 and this webpage was using SSL3.0. The solution was using the new version of the webpage.
Thank you all
Can't get the POST working? What's wrong?
Note: This works for a GET with autocomplete
GET works without signing the url
I'm following the Web services steps to Sign the URL with my "API Key"
Docs say"client id" still?
http://code.google.com/apis/maps/documentation/webservices/
2.Try sending the POST data with the signed URL (tried the unsigned signature aswell)
def signedUrl = "https://maps.googleapis.com/maps/api/place/add/json?key=xxxxxkeyxxxxxx&sensor=false&signature=xxxxxxxxxxsignaturexxxxxx"
String postData = "{'location': { 'lat': '-33.8669710','lng': '151.1958750'},'accuracy': '50','name': 'Google Shoes!'}"
URL urlPost = new URL(signedUrl);
URLConnection connection = urlPost.openConnection();
connection.addRequestProperty("Referer", "http://www.mysite.com");
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("CONTENT-TYPE", "text/json");
connection.setRequestProperty("CONTENT-LENGTH", postData.length() + "");
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
out.write(postData);
out.close();
String line;
StringBuilder builder = new StringBuilder();
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
while((line = reader.readLine()) != null) {
builder.append(line);
}
JSONObject json = new JSONObject(builder.toString());
println json
Returns a 403
"java.io.IOException: Server returned HTTP response code: 403 for URL:"
Simular to the "Java Access"section under they give an example of a GET
http://code.google.com/apis/websearch/docs/#fonje
Ok solved.
No signing the URL required
postData string was wrong
should have been
String postData = "{\"location\": { \"lat\": -33.8669710,\"lng\": 151.1958750},\"accuracy\": 50,\"name\": \"Google Shoes!\", \"types\":[\"bar\"]}"
