Downloading files to skydrive using java

advertisements

As per Skydrive api(http://msdn.microsoft.com/en-us/library/live/hh826531.aspx#uploading_files), I am passing the content of the image in byte[] in the body of the post request. the file creation happens on the skydrive server, but when i open it in skydrive it says "the file appers to be damaged or corrupted".

body of the post request

--A300x Content-Disposition: form-data; name="file"; filename="menu-icon.png" Content-Type: application/octet-stream

    [B@11f3043

--A300x--

the response from the server.

<html>
  <head>
    <script type="text/javascript">

    </script>
  </head>
</html>

code for converting the image into byte[]

byte[] image=FileUtils.readFileToByteArray(physicalfile);

Any clue?

EDIT: Following is the code snippet I use

I'm taking some parts from properties file.

env.properties
part1=--A300x\u000d\u000aContent-Disposition: form-data; name=\"file\"; filename=\"
part2=\"\u000d\u000aContent-Type: application/octet-stream\u000d\u000a\u000d\u000a
part3=\u000d\u000a--A300x--

java file

String part1=bundle.getString("part1");
String part2= fileName+bundle.getString("part2");
String part3=bundle.getString("part3");

byte[] imageByteArray=FileUtils.readFileToByteArray(physicalfile);

PostMethod postMethod= new PostMethod("https://apis.live.net/v5.0/"+folderPath+"/files?state="+getSkydriveClientId()+"&redirect_uri="+baseURL+"&access_token="+getAcessToken());
postMethod.setRequestHeader("Content-Type","multipart/form-data; boundary=A300x");
postMethod.setRequestBody(part1+part2+imageByteArray+part3);

HttpClient httpClient=new HttpClient();
httpClient.executeMethod(postMethod);

You appear to be calling toString() on your byte array - that's what's converting it to [B@11f3043. You haven't shown us any of the code you're using to make the request, but basically you need to avoid calling toString(). I don't know whether the API accepts a byte[], but you should at least try to find a method which takes one, as that would be appropriate for your content.

EDIT: Looking at the sample code, it appears you can pass in an InputStream to LiveConnectClient.uploadAsync - so just wrap your byte[] in a ByteArrayInputStream.
