While deleting index from Elastic Search, I am getting a HTTP error: 403. The code for deleting index is as follows:
static void DeleteIndex(string indexName)
{
// Delete index, recreate
if (_client.IndexExists(desc => desc.Index(indexName)).Exists)
{
var response = _client.DeleteIndex(desc => desc.Index(indexName));
if (!response.IsValid)
{
Console.WriteLine(response.ConnectionStatus);
Console.WriteLine("Press any key to continue");
Console.ReadKey();
}
}
}
Any pointers to how to remove the forbidden error?

Today i wanted to switch from GCM to FCM so i set up everything needed and wanted to implement the server side code. I used the gcm4j library and changed it so that the adress goes to https://fcm.googleapis.com/fcm/send.
So im doing the following:
FCM fcm = new FCMDefault(new FCMConfig().withKey(FCMGlobals.FCM_API_KEY));
FCMRequest request = new FCMRequest().withRegistrationId(android.getRegistration())
// .withCollapseKey(collapseKey)
.withDelayWhileIdle(true)
.withDataItem(FCMGlobals.FCM_PARAM_CODE, code)
.withDataItem(FCMGlobals.FCM_PARAM_USER_ID, "" + user.getId())
.withDataItem(FCMGlobals.FCM_PARAM_ADDITION, "" + addition);
ListenableFuture<FCMResponse> responseFuture = fcm.send(request);
Futures.addCallback(responseFuture, new FutureCallback<FCMResponse>() {
public void onFailure(Throwable t) {
log.error(t);
}
#Override
public void onSuccess(FCMResponse response) {
log.info(response.toString());
}
});
The implementation for that is:
protected FCMResponse executeRequest(FCMRequest request) throws IOException {
byte[] content = this.objectMapper.writeValueAsBytes(request);
HttpURLConnection conn = this.connectionFactory.open(this.fcmUrl);
conn.setRequestMethod("POST");
conn.addRequestProperty("Authorization", getAuthorization(request));
conn.addRequestProperty("Content-Type", "application/json");
conn.setDoOutput(true);
conn.setFixedLengthStreamingMode(content.length);
LoggerFactory.getLogger("FCMDefaultAbstract").info("Authorization: " + conn.getRequestProperty("Authorization"));
LoggerFactory.getLogger("FCMDefaultAbstract").info("Content-Type: " + conn.getRequestProperty("Content-Type"));
LoggerFactory.getLogger("FCMDefaultAbstract").info("send: " + new String(content));
try (OutputStream outputStream = conn.getOutputStream()) {
IOUtils.write(content, outputStream);
} catch (Exception e) {
throw new FCMNetworkException("Error sending HTTP request to FCM", e);
}
FCMResponse response;
try (InputStream inputStream = conn.getInputStream()) {
response = this.objectMapper.readValue(IOUtils.toByteArray(inputStream), FCMResponse.class);
} catch (IOException e) {
try (InputStream inputStreamError = conn.getErrorStream()) {
String str = inputStreamError != null ? IOUtils.toString(inputStreamError) : "No error details provided";
int responseCode = conn.getResponseCode();
if (responseCode < 500) {
throw new FCMNetworkException(conn.getResponseCode(), str.trim(), e);
} else {
throw new FCMNetworkException(conn.getResponseCode(), str.trim(), checkForRetryInResponse(conn), e);
}
}
}
response.setRequest(request);
response.setRetryAfter(checkForRetryInResponse(conn));
Iterator<String> iteratorId = request.getRegistrationIds().iterator();
Iterator<FCMResult> iteratorResponse = response.getResults().iterator();
while (iteratorId.hasNext() && iteratorResponse.hasNext()) {
iteratorResponse.next().setRequestedRegistrationId(iteratorId.next());
}
if (iteratorId.hasNext()) {
LOG.warn("Protocol error: Less results than requested registation IDs");
}
if (iteratorResponse.hasNext()) {
LOG.warn("Protocol error: More results than requested registation IDs");
}
return response;
}
Here the log output:
FCMDefaultAbstract Authorization: null
FCMDefaultAbstract Content-Type:application/json
FCMDefaultAbstract send: {"registration_ids":["dMpvzp*************************************2lRsSl_5lFET2"],"data":{"CODE":"201","USER_ID":"1","ADDITION":"1468083549493"},"delay_while_idle":true}
FCM FCMNetworkException: HTTP 401: No error details provided
The Authorization header is not null in fact. it is correctly set with my FCM API Key. Only the HTTPUrlConnection implementation says to return null if someone trys to access Authorization key.
As you can see i am not able to connect with FCM. The Code 401 means that authentication failed.
What could be the problem here?
Check that you are using a server type API-KEY, and not a client or browser API-KEY.
If you are using Firebase you can find the API-KEY in
Project Settings > Cloud Messaging
If you are using cloud console, or you are not sure which key you are using,
you can generate a new key through through https://console.cloud.google.com
Quoting the documentation
https://firebase.google.com/docs/cloud-messaging/concept-options#credentials
Server key: A server key that authorizes your app server for access to
Google services, including sending messages via Firebase Cloud
Messaging. [...]
Important: Do not include the server key anywhere in your client code.
Also, make sure to use only server keys to authorize your app server.
Android, iOS, and browser keys are rejected by FCM.
I'm trying to use Xamarin.Auth with the Xamarin Google-APIs to login to Google and access Drive. I've managed to get nearly everything working, but the authentication tokens seem to expire after about an hour. Everything works great for awhile, but after about an hour, when I attempt access, I get an Invalid Credentials [401] error and a leak:
Google.Apis.Requests.RequestError
Invalid Credentials [401]
Errors [
Message[Invalid Credentials] Location[Authorization - header] Reason[authError] Domain[global]
]
: GoogleDriveAgent: FetchRemoteFileList() Failed! with Exception: {0}

Invalid Credentials [401]
Errors [
Message[Invalid Credentials] Location[Authorization - header] Reason[authError] Domain[global]

objc[37488]: Object 0x7f151e50 of class __NSCFString autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug
//...more leaks.
I'd like to make sure I'm using Xamarin.Auth and the Google APIs as intended, so here is my code:
In my GoogleDriveService class, I've got an account store and a saved account:
AccountStore Store {
get {
if (m_store == null)
m_store = AccountStore.Create ();
return m_store;
}
}
Account SavedAccount {
get {
var savedAccounts = Store.FindAccountsForService ("google");
m_savedAccount = (savedAccounts as List<Account>).Count > 0 ? (savedAccounts as List<Account>) [0] : null;
return m_savedAccount;
}
}
I initialize a session and start the service:
void InitializeSession ()
{
Authenticator = new GoogleAuthenticator (ClientID, new Uri (RedirectUrl), GoogleDriveScope);
Authenticator.Completed += HandleAuthenticationCompletedEvents;
if (SavedAccount != null) {
Authenticator.Account = SavedAccount;
StartService ();
}
UpdateSignInStatus ();
}
bool StartService ()
{
try {
Service = new DriveService (Authenticator);
return true;
} catch (Exception ex) {
// Log exception
return false;
}
}
...and respond to authentication completed events:
void HandleAuthenticationCompletedEvents (object sender, AuthenticatorCompletedEventArgs e)
{
if (e.IsAuthenticated) { // Success
UpdateSignInStatus();
Store.Save (e.Account, "google");
Authenticator.Account = e.Account;
StartService();
LoginController.DismissViewController(true, null);
} else { // Cancelled or no success
UpdateSignInStatus();
LoginController.DismissViewController(true, null);
LoginController = null;
InitializeSession (); // Start a new session
}
}
Again, everything works fine, for awhile, but then the authentication expires. I understand that it should, but I thought the credentials saved in the AccountStore ought to still work.
In the Xamarin.Auth getting started docs, it says that calling Save again will overwrite the credentials and that "This is convenient for services that expire the credentials stored in the account object." Sounds promising...
So I tried another approach: having an IsSignedIn property that always overwrites the credentials in the getter...
public bool IsSignedIn {
get {
if (Authenticator == null) {
m_isSignedIn = false;
return m_isSignedIn;
}
if (Authenticator.Account != null) {
Store.Save (Authenticator.Account, "google"); // refresh the account store
Authenticator.Account = SavedAccount;
m_isSignedIn = StartService ();
} else {
m_isSignedIn = false;
}
return m_isSignedIn;
}
}
...and then I access IsSignedIn before any API calls (Fetching metadata, downloading, etc). It doesn't work: I'm still getting expired credentials errors shown above.
Is this a case of needing to refresh the token? What am I doing wrong?
Access tokens are supposed to expire relatively quickly. This is why after the first auth you also receive a refresh_token that you can use to get a new access token if the current one expires. Consecutive auths will not give you a refresh token necessarily, so make sure you keep the one you receive!
All you have to do after an access token becomes invalid is use the refresh_token and send an OAuthRequest to the token_url of Google's OAuth endpoint.
var postDictionary = new Dictionary<string, string>();
postDictionary.Add("refresh_token", googleAccount.Properties["refresh_token"]);
postDictionary.Add("client_id", "<<your_client_id>>");
postDictionary.Add("client_secret", "<<your_client_secret>>");
postDictionary.Add("grant_type", "refresh_token");
var refreshRequest = new OAuth2Request ("POST", new Uri (OAuthSettings.TokenURL), postDictionary, googleAccount);
refreshRequest.GetResponseAsync().ContinueWith (task => {
if (task.IsFaulted)
Console.WriteLine ("Error: " + task.Exception.InnerException.Message);
else {
string json = task.Result.GetResponseText();
Console.WriteLine (json);
try {
<<just deserialize the json response, eg. with Newtonsoft>>
}
catch (Exception exception) {
Console.WriteLine("!!!!!Exception: {0}", exception.ToString());
Logout();
}
}
});
I'm trying to delete a file from bucket using following code. but I can still view the file via browser
if (isValidFile(s3Client, BucketName, keyName)) {
try{
s3Client.deleteObject(new DeleteObjectRequest(BucketName,keyName));
}catch(Exception e){
e.printStackTrace();
}}
Why is delete not working??
For me, working here is an option.
public boolean deleteFileFromS3Bucket(String fileUrl) {
String fileName = fileUrl.substring(fileUrl.lastIndexOf("/") + 1);
try {
DeleteObjectsRequest delObjReq = new DeleteObjectsRequest(bucketName).withKeys(fileName);
s3client.deleteObjects(delObjReq);
return true;
} catch (SdkClientException s) {
return false;
}
}
If the object is public, it may cached by browser. Besides, DELETE OBJECT operation is eventual consistent
When an Action is called and throws a specific exception, I use an ExceptionFilterAttribute that translate the error into a different response as HttpStatusCode.BadRequest. This has been working locally, but we pushed it to a server and now when I get the BadRequest I do not get any information in the reponse. What am I missing?
public override void OnException(HttpActionExecutedContext actionExecutedContext)
{
MyException ex = actionExecutedContext.Exception as MyException;
if (ex == null)
{
base.OnException(actionExecutedContext);
return;
}
IEnumerable<InfoItem> items = ex.Items.Select(i => new InfoItem
{
Property = i.PropertyName,
Message = i.ToString()
});
actionExecutedContext.Result = new HttpResponseMessage<IEnumerable<InfoItem>>(items, HttpStatusCode.BadRequest);
}
Edit: When I hit the service locally the body is included. It seems the problem is when hitting the service from a remote machine.
Try this:
GlobalConfiguration.Configuration.IncludeErrorDetailPolicy =
IncludeErrorDetailPolicy.Always
This code:
private void Submit_Click(object sender, RoutedEventArgs e)
{
user temp = new user();
temp.Username = UserName.Text;
temp.Password = Password.Text;
dataBase.AddTouser(temp);
IAsyncResult result = dataBase.BeginSaveChanges(new AsyncCallback (OnSaveChangesCompleted), temp);
}
void OnSaveChangesCompleted(IAsyncResult result)
{
try
{
string name = ((user) result.AsyncState).Username.ToString();
dataBase.EndSaveChanges(result);
}
catch (DataServiceRequestException ex)
{
MessageBox.Show("OnSaveChangesCompleted Error: " + ex.ToString());
}
}
produces this error:
The HTTP verb POST used to access path '/Membership/user/' is not allowed
I think it may have something to do with this being incorrect:
public static void InitializeService(IDataServiceConfiguration config)
{
config.SetEntitySetAccessRule("*", EntitySetRights.All);
config.SetServiceOperationAccessRule("*", ServiceOperationRights.All);
}
Or it may have something to do with the ASP.NET configuration, but I am not sure what to do in there.
I am trying to use Silverlight, DataEntityFramework, and a WCF Service all together (for the first time) and have no idea where exactly the solution to this problem lies.
I got a similar problem, it seems that there are problems with the url rewriting.

You have to remove the mapping of ‘*’ to aspnet_isapi.dll in yourIIS settings.
