Hi John,
Thanks for this, seems to be heading in the right direction - although
I've now hit a weird issue with a 401 Unauthorised error. At the
moment, I'm not sure where this is coming from as the accessor and
client have been set and other posts are working. I changed the code
to below:
public static class InputStreamMessage extends OAuthMessage
{
public InputStreamMessage(String url, InputStream body,
List<Parameter> params) {
super("POST", url, params);
this.body = body;
}
private final InputStream body;
@Override
public InputStream getBodyAsStream() throws IOException {
return body;
}
}
Also, I created a postImage function:
public OAuthMessage postImage(OAuthMessage request, ParameterStyle
params) {
OAuthMessage return_value = null;
try {
return_value = client.invoke(request, params);
} catch (OAuthProblemException e) {
int status_code = e.getHttpStatusCode();
if (200 <= status_code && status_code < 300) {
// Not really a problem.
} else {
e.printStackTrace();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return return_value;
}
And this is how I invoke it:
try {
OAuthMessage response = null;
File input_file = new File(filename);
InputStream input = new FileInputStream(input_file);
OAuthMessage request = new InputStreamMessage(post_url, input,
OAuth.newList("photo[body]", post_message));
request.getHeaders().add(new OAuth.Parameter("Content-Type", "image/
jpeg"));
request.getHeaders().add(new OAuth.Parameter("Content-Length",
""+input_file.length()));
response = oauth_request.postImage
(request,ParameterStyle.AUTHORIZATION_HEADER);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I had to add the Content-Length, as it was getting a 411 error that
the length was not set. Any ideas why this would be getting
unauthorised (except the obvious answer that it's coming from the
other end, but I need to try eliminate anything at my end).
Thanks
