How to get Facebook Rate Limit Header using Facebook4J?

QUESTION

How to get Facebook Rate Limit Header using Facebook4J?

Asked 2017-May-31 at 06:46

According to Facebook Docs

If your app is making enough calls to be considered for rate limiting by our system, we return an X-App-Usage HTTP header. [...] When any of these metrics exceed 100 the app will be rate limited.

I am using Facebook4J to connect my application to the Facebook API. But I could not find any documentation about how I can get the X-App-Usage HTTP header after a Facebook call, in order to avoid being rate limited. I want to use this header to know dinamically if I need to increase or decrease the time between each API call.

So, my question is: using Facebook4J, is possible to check if Facebook returned the X-App-Usage HTTP header and get it? How?

There is a getResponseHeader method for the response of BatchRequests in facebook4j see Facebook4j code examples

You could try getResponseHeader("X-App-Usage")

The comment count is a non-default field so you need to explicitly tell the Facebook API to include it in the response. You can use the Reading class to achieve this:

As you can see, the stack trace does not reveal anything from my application. This exception happens purely in the infrastructure. What does it mean and how can I reproduce that? Also, I don't get why there's Jackson in the stack trace. I have no where any JSON output in my application.

At the end I want to understand if my application has an issue. If so, fix that. If not, I don't want to have this in my log as an ERROR.

This is caused because the client is closing the connection before Tomcat has the chance to write out the response.

The main perpetrator of this exception tends to be "Internet Explorer" because of how it handles resource connections (like downloading JavaScript, css, icons etc); if it decides it no longer needs the resource, it closes the connection before the server has a chance to write out to it. I also see it more when you are using Angularjs, or other SPA frameworks, in IE. You will know it is caused by IE because the request resource path with be to a resource file (as described previously).

The second (or equally?) most common culprit could be users refreshing the page multiple times before it has a chance to finish loading, or the user navigating away before the page finishes loading.

The third culprit, and less common but WAY more infuriating, is when you are calling services on your own network. You will see a "ClientAbortException" on the called service and a "SocketException: connection reset" on the client service. The cause is normally because of badly configured firewalls. I talked with my Systems Administrator, and she said that the last time it happened to me it was because the replication traffic was too high during peak usage so the firewall could not return the packet in time. The solution was to throttle traffic from specific sources (such as replication) during peak usage of other essential applications. I suppose you could duplicate this error by simulating heavy usage and traffic through the firewall.

QUESTION

Run Maven ant plugin after the .war is deployed?

Asked 2017-Mar-21 at 06:13

I'm currently trying to create a docker image based on my war file which will be created within the target folder when deployed. But the ant plugin executes the command before the maven war file is deployed into target folder. Due to that though it try to create a docker image it won't find the necessary .war file to add since it hasn't being deployed into target folder.

The ant plugin is also declared under a separate profile called docker. Though I read about the Maven Lifecycle Doc, couldn't find a proper approach to achieve this.

Here is my .pom file

I don`t have the exact answer for this question. But i try to explain our approach for solving this issue. Maven is a good tool for building standard project with identical structure and build phases. If you want get something more complex maven will resist it. Therefore we had decide a bit different approach:

Maven is used only for building application (jar, war, etc...)
All docker artifacts creates with bash scripts, which contains commands for building application with maven, building docker image and pushing it to repository.

I think for this purpose bash more convinient and flexible then maven
