My application is getting slow when I try to make the Titanium.Network.createHTTPClient call though I'm making the call in the Alloy.js and the webservice is not depended on the screen as its a background call.
Alloy.Globals.xhr = Titanium.Network.createHTTPClient({
async: true,
onerror : function(e) {
},
timeout : 9000 // in milliseconds
});
My screen is getting halted until I get the response. How to call the service in background without effecting the screen/application performance

Android Platform - Not working
iOS Platform - working
As pointed out in the documentation:
By default, the HTTPClient makes asynchronous requests. Asynchronous requests do not block the application and use callbacks to process responses when they are received.
Synchronous requests block the execution of the application until it receives a response. On the iOS platform, you can make synchronous requests by setting the optional async parameter to false when calling the open method.
The Android platform does not support synchronous requests.
There is no async parameter for the constructor, only inside the open() method for iOS: http://docs.appcelerator.com/platform/latest/#!/api/Titanium.Network.HTTPClient-method-open (optional 3rd parameter).
So the http request might not be the source for the slow down.
What you could try is to move the HTTPClient part out of the global space into a library or into the controller itself (for testing purposes). I use it in a Podcatcher app without blocking the UI and download multiple files without blocking the UI.

Here, instead of Thread.Sleep in Custom Action, I have to make an http call which sometimes takes more than 15 secs.
I need some help in injecting a service with http call in the Sleep Custom Action.
I have been trying to intercept a server request using Cypress' intercept method.
I have noticed that Cypress can intercept requests made through the front-end/browser, however, the intercept method doesn't work if I make a request directly to the back-end server.
Let me clarify what I mean:
One thing is intercepting a request that the front-end/browser makes to the back-end server.
Another thing is intercepting a call that doesn't use the browser but calls directly the back-end endpoint.
For example:
I can create a user using the front-end interface
or I can create a user calling the back-end endpoint directly (directly calling the server).
Coming back to my question. Is there a way to intercept a call that was made directly to the back-end endpoint?
This is what I have tried so far:
I wrote a regex to intercept api/v0/customers
I then made a request to http://locahost:5440/api/v0/customers (which is the URL of the server)
Finally, I waited for the request to happen
Timeout request using Cypress intercept method
cy.intercept(/^\/api\/v0\/customers\/$/).as('createCustomer');
cy.request(createCustomer(customerData, headers));
cy.wait('#createCustomer').then(({ status, body }) => {
const customerId = body.customer_id;
console.log(body);
expect(status).equal(201);
});
Here's the problem: There was a timeout error.
As you can see in the image, I'm making a request to http://locahost:5440 which is the server URL. NOTE: I made sure the server was up and running.
The regex is also correct and it will match the endpoint http://locahost:5440/api/v0/customers
I suspect that intercept only works for requests being made through the browser. Is this assertion correct? I couldn't find this answer anywhere in the Cypress docs.
Is there a way for me to intercept a call being made directly to a server (not using the browser)?
You don't have to intercept the requests you explicitly make with cypress, just use .then to get the response, like this:
cy.request(createCustomer(customerData, headers)).then((response) => {
const customerId = response.body.customer_id;
console.log(response.body);
expect(response.status).equal(201);
});

I have build a simple cloud-SDK based application for adding as a Webhook in Enterprise messaging queue to receive the events as soon as it gets inside the queue.
I have an OPTIONS and POST function. OPTIONS is for the handshake with the queue and it works.
Now, when there is message in the Queue, it hits my application with the POST block but the request body is coming as empty object.
I have tried the same from the postman, i'm able to receive the data in request body. Only from the Enterprise messaging queue, the data is empty.
In contrast, to verify this, I have used a Express based nodejs application, there i'm able to receive the data from the queue.
What am i missing in the Cloud-SDK based code ?
POST block, looks like this
#Post('ems-events')
receiveEmsEvents(#Body() requestBody: string, #Req() req:Request) {
Logger.log("Event Received with Data:");
Logger.log(requestBody);
Logger.log(req.body);
Logger.log("Log over--");
Logger.log(Object.keys(req));
return {};
}
The SAP Cloud SDK for JavaScript does not offer any support for Enterprise Messaging as of today. The code you're writing here is most likely Nest.js code, which is an independent framework.
That being said, Nest.js does run Express.js under the hood by default. So if you've been able to make it work in Express, you should be able to make it work in Nest.
I have an API which I consume from a VueJS app, backend is handled through Laravel 5.2.
I have setup automatic session timeout after 15min, but if happens you're in the site and try to do anything, I have a loading screen, and it freezes as you're unauthorized.
I wanted to know if there's any global method to read Unauthorized response when all requests are made.
I don't know what this is called, so I wouldn't know how to properly Google the feature.
I'm using VueJS Resource $http library to manage all requests.
Thanks!
I've finally made my way to the right documentation, it was under Vue-Resource, and these are called Interceptors.

I have a Worklight 6.1.0.1 hybrid app that I'm running on iOS. The app uses adapter-based authentication. The app prepares the invocation data makes the following call when the Login button is clicked:
singleStepAuthRealmChallengeHandler.submitAdapterAuthentication(invocationData, {});
If the WL service is down, or if the mobile device has no network access, the invocation will timeout. I see the following in the Xcode console:
defaultOptions:onFailure Request timed out for http://myipaddress:10080/myapp/apps/services/../../invoke. Make sure the host address is available to the application (especially relevant for Android and iPhone apps).
How can I capture this timeout event, so that I can update the UI with a proper message?
Update May 23rd based on comments:
What is your exact flow?
You should first use WL.Client.connect({onSuccess: ..., onFailure:...});
If connection to the server is successful, you will enter the challenge handler. Otherwise, you will enter onFailure and there you can create the custom error handling.
Previous answer attempt:
The below is when trying to connect() to the Worklight Server.
If you want custom handling for when the client fails connecting to the server I believe you need to enable and use the option onConnectionFailure in initOptions.js:
var wlInitOptions =
// # The callback function to invoke in case application fails to connect to Worklight Server
//onConnectionFailure: function (){},
}
Otherwise, Worklight's default dialog will be displayed.
