I have an application in which you can search for videos repeatedly. Do I need to new Vimeo everytime I call $vimeo->request?
$vimeo = new Vimeo(APPLICATION_ID, APPLICATION_SECRET, ACCESS_TOKEN);
$vimeo->request('/videos?query=cars');
You only need to construct a new instance of the Vimeo object if you want to switch to different application id's secrets, or tokens.

I have a Line-of-Business (LoB) Windows 8.1 Store application I developed for a client. The client side-loads it on several Windows 10 tablets. They use it in an environment where WiFi is spotty at best and they would like to get some sort of notification inside the app, regardless of what page they are on, notification that will let them know that they've lost connectivity to the network. I have created a method on my Web API that is not hitting the repository (database). Instead, it quickly returns some static information regarding my Web API, such as version, date and time of the invocation and some trademark stuff that I'm required to return. I thought of calling this method at precise intervals of time and when there's no response, assume that the Web API connectivity is lost. In my main page, the first one displayed when the application is started, I have the following stuff in the constructor of my view model:
_webApiStatusTimer = new DispatcherTimer();
_webApiStatusTimer.Tick += OnCheckWebApiStatusEvent;
_webApiStatusTimer.Interval = new TimeSpan(0, 0, 30);
_webApiStatusTimer.Start();
Then, the event handler is implemented like this:
private async void OnCheckWebApiStatusEvent(object sender, object e)
{
// stop the timer
_webApiStatusTimer.Stop();
// refresh the search
var webApiInfo = await _webApiClient.GetWebApiInfo();
// add all returned records in the list
if (webApiInfo == null)
{
var messageDialog = new MessageDialog(#"The application has lost connection with the back-end Web API!");
await messageDialog.ShowAsync();
// restart the timer
_webApiStatusTimer.Start();
}
}
When the Web API connection is lost, I get a nice popup message that informs me that the Web API is no longer available. The problem I have is that after a while, especially if I navigate away from the first page but not necessary, I get an UnauthorizedAccessException in my application.
I use the DispatcherTimer since my understanding is that this is compatible with
UI threads, but obviously, I still do something wrong. Anyone cares to set me on the right path?
Also, if you did something similar and found a much better approach, I'd love to hear about your solution.
Thanks in advance,
Eddie
First, If you are using Windows Store Apps, then you could possibly use a Background task to check poll for the status of the web api instead of putting this responsibility on your view model, its not the viewmodels concern
Second, if you are connecting from your Windows store app to your API then one successful authentication/ authorization for the first time, how and where do you store the token (assuming you are using token authentication). If you are (and ideally you should), is there a timer that you start which is set to the token expiration time? Is your local storage getting flushed somehow and loosing the aurthorization data?
Need more information.
Alright I have my sqldb hosted online and can access it using phpmyadmin what i would like to do is create tables and add items to the tables via adobe flex builder 4.6 desktop AIR application.
Anyone know if i am able to do this, the idea for the program is so person at position A can enter a name and person at position B can then use his program to read those names
According to Accessing mysql from Adobe flex/AIR, AIR is unable to access MySQL servers directly, so you'll have to use web services or some custom API do to this. But yeah, sure it's possible to do what you want.
I agree with Isaac. However, I want to add that it is good coding practices to not allow client side applications modify a database directly. In the applications that I have built, I like to use PHP to set-up an API that then interacts with the database. The AIR application then the interaction with the API using HTTP Requests.
Following code shows how to perform a URL request from the Adobe Website.
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/URLRequest.html
var url:String = url location of the API;
var request:URLRequest = new URLRequest(url);
var variables:URLVariables = new URLVariables(); //create variables to pass to the API
variables.exampleSessionId = new Date().getTime(); //create variables to pass to the API
variables.exampleUserLabel = "guest"; //create variables to pass to the API
request.data = variables; //Add the variables to the request
request.method = URLRequestMethod.POST; //Set the method of the Request GET, POST, PUT
navigateToURL(request); //Executes the request
You'd probably like something like https://backendless.com/ for this.
after reading the oauth documentation on box's website, I understand the steps to get access_token and refresh_token, which requires authorization_code.
step1: send Get request to https://www.box.com/api/oauth2/authorize?response_type=code&client_id=CLIENT_ID&state=authenticated&redirect_uri=https://www.appfoo.com
step2: after entering credentials of box in browser and then click the "Allow" button, redirect to the specified redirect_uri with state=authenticated&code=AUTHORIZATION_CODE
step3: now with the AUTHORIZATION_CODE in the redirect url from step2, getting access_token can be done programmatically, by sending POST request to https://www.box.com/api/oauth2/token with AUTHORIZATION_CODE, client_id, client_secret in body and then parsing the returned json response.
My question is: is it possible to programmatically do step1 and step2 instead of via browser?
thank you very much!
The current OAuth 2 flow requires the user to go through the browser and can't be done programmatically.
It is possible, just imitate every form with cURL and on second step post cookies.
First time you will need 3 requests, next time only one (if refresh_token isn't expired, otherwise 3 again)
The point about imitating the browser transactions is a good one but instead of using cURL you would want to use a higher level tool like mechanize (available for ruby, perl and python). It will handle the cookies for you and can programatically traverse forms and links. Good for page scraping and writing scripts to order hot concert tickets from TicketMaster too!
If you have the authorization code, you then should be able to get the OAuth Token(access_token, refresh_token) via SDK, correct?
In response to aIKid, this is what I first do to get a BoxClient
BoxClient client = new BoxClient(clientId, clientSecret);
Map<String,Object> authToken = new HashMap<String,Object>();
authToken.put("exprires_in","3600");
authToken.put( "token_type","bearer");
authToken.put("refresh_token", clientRefreshToken);
authToken.put("access_token",clientAccessToken);
BoxOAuthToken oauthToken = new BoxOAuthToken(authToken);
client.authenticate(oauthToken);
return client;
Then, I have this to create a new user,
BoxUser createdUser = new BoxUser();
BoxUserRequestObject createUserRequest = BoxUserRequestObject.createEnterpriseUserRequestObject("someEmail.domain.com", "test user");
createdUser = client.getUsersManager().createEnterpriseUser(createUserRequest);
Now I'm trying to figure out how to do the RUD part of my CRUD operations on users and groups.
I'm trying to make a simple video chat using Flex framework and red5 server. It's an application with 2 video displays. With connection to the server more or less figured out. However, I do not understand how to transfer user1 stream to user2.
Here is functions i use to transfer webcam image to the server and to get the stream.
public function appendStream(connection:NetConnection):void {
myNetStream = new NetStream (connection);
myNetStream.attachAudio(cameraVideo.getMic());
myNetStream.attachCamera(cameraVideo.getCam());
myNetStream.publish("videochat" , "live");
}
public function getStream(connection:NetConnection):Video {
guestNetStream = new NetStream(connection);
video2.attachNetStream (guestNetStream);
guestNetStream.play("videochat");
return video2;
}
As you can see, i am getting my own stream.
Is it possible to solve the problem by flex, or I need programming on the server side?
You dont need separate rooms, simply use unique stream names for each client. The ez way is to create your steam names ahead of time and pass them to your swf via flashvars; that way you dont have to pair them with some other complicated scheme.
For a bit more background in red5, a room is a type of scope and a scope can contain other scopes which includes broadcast scopes, shared object scopes, and rooms. There is no limit on the number of these scopes other than the amount of RAM on the server itself.
You need to have two "rooms" instead of one "videochat". User1 must publish to "videochat1" and stream from "videochat2". Vice versa for user2.
And please remove Flex mention here since there's nothing related to Flex UI framework here
I have a small multiplayer Flash game in which you can display a player profile by clicking at his or her avatar:
const PROFILE_URL:String = 'http://myserver/user.php?id=';
try {
navigateToURL(new URLRequest(PROFILE_URL+id), '_blank');
} catch(e:Error) {
}
This works well, but now I'd like to extend the user.php, so that players can add comments about each other. For authorization I'd like to use HTTP cookies, passed from the game.swf to the user.php.
(I don't want use GET or POST here, because GET will have the auth. variables in the URL and players might occasionaly send that URL around or post it in my forum. And POST will ask to re-post the request when you reload).
My problem is that I can't find the way to set HTTP cookies through the navigateToURL() method. Please advise me
Regards,
Alex
You could first authenticate by logging in via a seperate call, for example login.php and that script would start a session. Then all other calls to the same domain would already have the session started and you could check authentication. No need to worry about cookies when PHP can do it for you.
Assuming that you already have the cookie value in your swf you should be able to use the URLRequestHeader together with the URLRequest as follows:
var header:URLRequestHeader = new URLRequestHeader("Cookie", "<the cookie>");
var request:URLRequest = new URLRequest("http://example.com/script.php");
request.requestHeader.push(header);
request.method = URLRequestMethod.POST;
navigateToURL(request, "_blank");
Under certain circumstances, the browser will send the cookie to the server if it has been already set even if you don't explicitly include it in the request. This depends on the browser and the version of the Flash Player. You might also need to adjust your crossdomain.xml file.
Also note that there might be security implications of passing around an unencrypted cookie token. See Firesheep.
