Hello, I am using new fabric twitter kit and really like it so far, but I’ve found it lacking of image upload functionality so I decided to call api from retrofit. Problem is I got 400 error so I suspect I am doing something more with authorization. Could someone point me out what is wrong with my code? (sorry for quality)
final File photo = new File("<path here>");
TypedFile typedFile = new TypedFile("image/*", photo);
final TwitterSession session = Twitter.getSessionManager().getActiveSession();
if (session != null) {
final TwitterAuthToken authToken = session.getAuthToken();
RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint("https://upload.twitter.com")
.setLogLevel(RestAdapter.LogLevel.FULL)
.setRequestInterceptor(new RequestInterceptor() {
@Override
public void intercept(RequestFacade request) {
byte[] b = new byte[32];
new Random().nextBytes(b);
String randomBytes = null;
try {
randomBytes = URLEncoder.encode(String.valueOf(b), "UTF-8");
} catch (UnsupportedEncodingException e) {
Log.e(TAG, e.getMessage());
}
long currentTimeMillis = System.currentTimeMillis();
String token = session.getAuthToken().token;
String signature = String.format("oauth_consumer_key=%s&oauth_nonce=%s&oauth_signature_method=HMAC-SHA1&oauth_timestamp=%s&oauth_token=%s&oauth_version=1.0", MainApplication.TWITTER_KEY, randomBytes, currentTimeMillis, token);
String finalSignature = null;
try {
finalSignature = sha1(signature, MainApplication.TWITTER_SECRET + "&" + authToken.secret);
} catch (UnsupportedEncodingException e) {
Log.e(TAG, e.getMessage());
} catch (NoSuchAlgorithmException e) {
Log.e(TAG, e.getMessage());
} catch (InvalidKeyException e) {
Log.e(TAG, e.getMessage());
}
String header = String.format("OAuth oauth_consumer_key=\"%s\", oauth_nonce=\"%s\", oauth_signature=\"%s\", " +
"oauth_signature_method=\"HMAC-SHA1\", oauth_timestamp=\"%s\", oauth_token=\"%s\", oauth_version=\"1.0\")", MainApplication.TWITTER_KEY, randomBytes, finalSignature, currentTimeMillis, token);
request.addHeader("Authorization", header);
}
})
.build();
CustomService service = restAdapter.create(CustomService.class);
service.upload(typedFile, new Callback<TwitterMedia>() {
@Override
public void success(Result<TwitterMedia> twitterMediaResult) {
Log.d(TAG, "uploaded file");
}
@Override
public void failure(TwitterException e) {
Log.d(TAG, "file upload failed" + e.getMessage());
}
});
public static String sha1(String s, String keyString) throws
UnsupportedEncodingException, NoSuchAlgorithmException,
InvalidKeyException {
SecretKeySpec key = new SecretKeySpec((keyString).getBytes("UTF-8"), "HmacSHA1");
Mac mac = Mac.getInstance("HmacSHA1");
mac.init(key);
byte[] bytes = mac.doFinal(s.getBytes("UTF-8"));
return Base64.encodeToString(bytes, Base64.URL_SAFE);
}
interface CustomService {
@Multipart
@POST("/1.1/media/upload.json")
void upload(@Part("media") TypedFile file, Callback<TwitterMedia> cb);
}
static class MyTwitterApiClient extends TwitterApiClient {
public MyTwitterApiClient(com.twitter.sdk.android.core.Session session) {
super(session);
}
public CustomService getCustomService() {
return getService(CustomService.class);
}
}
thank you for the answers !
PS TwitterMedia is class mapped to request from media/load api:
