How can I fetch data from facebook using a query string in salesforce?
This is what I have:
I am not fetching data so what can I do?
Have you called Http's send method after this?. I guess you have but are not getting any response back?
Any external site you call from Apex must be registered in the Remote Site Settings. Make sure to add Facebook's URL under Admin Setup > Security Controls > Remote Site Settings

I want to pass the user id (100) to moodle and then get a JSON string about the stored data of the user with the id (100). Is there a way or a web service for this?
Thx
First of all, you need to enable Moodle web services, you can follow this link, then add the "core_user_get_users" function to your external web service, then you can create criteria to search and get user data.
Samples:
webservice endpoint: https://<MOODLE_URL>/webservice/rest/server.php?wstoken=<YOUR_TOKEN>&wsfunction=core_user_get_users&moodlewsrestformat=json&criteria[0][key]=username&criteria[0][value]=<USERNAME>
webservice endpoint: https://<MOODLE_URL>/webservice/rest/server.php?wstoken=<YOUR_TOKEN>&wsfunction=core_user_get_users&moodlewsrestformat=json&criteria[0][key]=id&criteria[0][value]=<ID>
For other response formats change "moodlewsrestformat" in the request.
I'm currently working on a VueJS project on which I've just implemented a SSO system designed by the Portuguese government using our national identity cards, but I'm having some issues parsing the response from the external authentication server.
Here's a small GIF of my problem: https://gfycat.com/threadbarepossiblebagworm
The workflow is as follows:
User clicks on Authenticate.
User chooses "Login via ID Card"
User gets redirected to the external Authentication Provider
User logins with his ID Card.
External Authentication provider then sends back a POST method to the callback URL that is provided.
I read/parse the callback
The issue lies in step 6... The external authentication provider uses the callback URL I provided but I get this error
Cannot POST /users/callback
If this was a typical NodeJS I could just use
router.post('/callback' ....)
Is there a way I can read that callback in VueJS?
I've found this similar issue https://forum.vuejs.org/t/cannot-post-handling-form-post-from-an-external-site/41194/1 but no one managed to offer him a solution.
Thanks in advance!
EDIT: Before you ask, yes, that '/users/callback' is defined on router.ts and if I go to that route it does show a page. It's just not designed for POST methods afaik
Vue is a front-end framework, which means it doesn't have direct access to POST requests by default.
For production, are you running an npm script like "npm run build" and then serving the files that appear in the "dist" folder on a webserver, say Apache? Then you would have to respond to the POST request in Apache.
You could then store their authentication result "farther toward the backend" than Vue and have Vue grab it with vuex.
I would like to allow users to login my web application using "Sign in with LinkedIn" Javascript SDK.
https://developer.linkedin.com/docs/signin-with-linkedin
Once user logging in using LinkedIn i need to transfer (post) the Member ID to my application server and look for a user with that linkedIn memberid in my application database.
The problem is that i couldn't find an option to validate the member id i am getting from the javascript SDK in the server side in order to make sure the end user didn't manipulate it using Chrome Dev tools for example.
Without an option to validate the value on a server side, i assume that users will be able to change the member id value before it post to the server. Am i right?
i found few old threads but the solutions do not work
If you want server side validation you should use the Oauth 2.0 approach.
Start by providing the initial link:
Li Auth
And continue from there:

I'm trying to stream the real time public feeds using Facebook Web-hook API. Here I'm trying to set up a page subscription in Web-hook console. There is a field called Callback URL. What is this URL about?
I have also tried going through the documentation for Setting up callback URL. but I Couldn't figure out.
https://developers.facebook.com/docs/graph-api/webhooks#setup
Cant the callback URL be SSL localhost? Whenever I try to give a localhost URL i get a error message "Unable to verify provided URL".
You can forward the request to localhost with the following:
Download and install ngrok from https://ngrok.com/download
./ngrok http 8445
Subscribe your page to the Webhooks using verify_token and https://<your_ngrok_io>/webhook as callback URL.
Talk to your bot on Messenger!
Facebook will make a request to that URL from their servers to deliver the updates – so of course it has to be publicly reachable over the internet, which a localhost address obviously isn’t.
Facebook will send a request to that URL if any data for the object and fields that you subscribed for changes. And what the data structure looks like, is described in the docs. For page fields it returns the new content directly; for user fields it will only tell you which fields have changed, so that you can then make a request for that data.
You can only get real-time updates for pages that you have admin access to. And the Public Feed API is not deprecated; but access to it is limited to a small set of Facebook partners. You can not apply to become one – if you absolutely need this kind of data, then you’ll have to contact one of those partners and have them develop a solution for you.
I think it means that you need a server which has a fixed IP address. If you want to use the real time update from the Facebook, you need to build a server which receive the post request from Facebook and meanwhile keep a long connection to you endpoint so that the endpoint can receive message pushed by the server.
You have to write a webhook to get the fb request from fb server as well as the webhook should be running in a public ip address, this public url is the one to be filled it out on the callback url box. So that the fb server could update you through the url which is nothing but the url of running webhook. To get the public url address for fb recognising your webhook, you can use ngrok or can host your webook in heroku.
Im writing a user registration mechanism by hand so I dont want to use existing plugins or something.
Im wondering what the best way would be. I planning to do the following abstract steps:
Writing an component which is in charge to output a button which calls the facebook-api --> login in via facebook (Im getting token and user name/id)
In my route im using that Data to call the REST-Server-Backend of my app. I will pass the token as well as the username/id to the Server. (POST api.myapp.com/users)
The Server recieves the request and will validate via Facebook-API
the user data and token on its own --> if valid: Add new user to
database.
If the user wants to login now (after registration) he will do again
step no.1 and than will ask the server if the user is existing. But
how: Since ember suggest that the REST-Server is somekind of a
CRUD-Server and using the store is for working for model data only, there
is no possiblity to do a "logic"-call to the server like "ask
him if user with id is existing". Should I call "GET ../users/" and than check in my route if the sum of the returned records are smaller than 1?
So is that a common pattern?
Sounds like a fairly simple OAuth workflow but obviously refer to the facebook docs. As far as point 4 is concerned, I would suggest that yes, on login you make a request for the login route on your server (which should abstract the facebook OAuth call), and if the user is authenticated, then send down the user resource, otherwise redirect them to the login and send down some sort of 401 HTTP error.
As all your API calls should be authenticated too your user won't be able to access any protected API resources.
I would also suggest you look into an ember plugin like ember-simple-auth which also supports OAuth.
You can find more information about OAuth2 workflows here.
