Facebook checkin - facebook-graph-api

I am using the following code for location
function graphlocation(){
FB.api('/me', function(response) {
var location = response.location.name;
alert('Post ID: ' + location);
});
}
It gives same location every time I use it even if I change my location in Facebook. I have taken user permissions for checkin.
Any idea what can be wrong here ?

That location is what is set in your user profile under the living section. That location is static to what you set it to in your profile and not tied to any checkins. Also perhaps the API is caching your information. Play around here: https://developers.facebook.com/tools/explorer to see graph requests in real time. Mine always updated no matter where I changed my living current city selection to. What do you get when you check it with the graph API explorer tool?

How can I share a Basic Authentication header across a Collection in Postman?

I have a collection of basic API queries against our local JFrog Artifactory swarm to test whether or not the version of a requested library has been made available on our enterprise package manager.
As an example, I'll use angular.
https://artifactory.foo.com/artifactory/api/storage/npm-approved/angular/-
This returns a nice little list of versions that are available.
I have a test running against this particular query to ensure the appropriate version is available in said result set.
var neededVersion = '1.4.14';
var jsonData = JSON.parse(responseBody);
var versions = jsonData.children;
var hasNeededVersion = false;
for(var version in versions) {
if(versions[version].uri.indexOf(neededVersion) >= 0) {
hasNeededVersion = true;
}
}
tests[neededVersion] = hasNeededVersion;
Great tool, as with the 40+ libraries I'm constantly needing to get updates on, I have a collection of queries to all our project dependencies in the same manner. I invoke the runner and point it at the collection and review all my test results. HUGE improvement.
Then I had to change my password.
I had to go through and update the 'Authentication' header for each and every entry. This seems arduous. I looked into setting the header in Environments and globals, but nothing seemed to work.
The thought would be to just update my credentials in one place.
Anyone have any advice?
Type the username:password in this online tool to get the Authentication header
admin:1234 in base64 is YWRtaW46MTIzNA==
In Postman, goto Settings - Manage Environments - Globals and add a global variable called basic_auth with a value of Basic YWRtaW46MTIzNA==
In each request go to the request Headers and add a key Authorization with a value of {{basic_auth}}
Then when the password changes you can update the global variable and all requests will use the new value.
Rather than saving the Auth header, try setting your username and password in the Authorization tab. Postman will use that info to create the Authorization header when the request is sent. Then you would be able to use Environment Variables (or even collection variables) which would only need to be updated in one place.
Instructions:
Set up environment/collection variables for 'username' and 'password', and save
In each request:
In the Heaaders tab, remove the Authorization header
In the Authorization tab, select the Type: Basic Auth
In the Username field, enter {{username}}
For the Password field, click "Show Password", and enter
{{password}}
Hope this helps others :)

Get comments of public facebook post

I'm trying to download every comment on a public facebook post (it's one of those "can you do this basic algebra problem" posts - I want to see what percent of the comments get it right).
The Graph API Reference shows that I should be able to just GET graph.facebook.com/v2.5/{object-id}/comments.
I believe the object-id of this post is {user-id}_{post-id}, where post-id is the id in the url. So given this url:
https://www.facebook.com/beth.mansfield.9/posts/10207885721596563
The user-id of facebook.com/beth.mansfield.9 is 1101752663 (from findmyfbid.com), and the post-id is 10207885721596563 (from the url), which makes the object-id="1101752663_10207885721596563".
When I try graph.facebook.com/v2.5/1101752663_10207885721596563/comments in the Graph API Explorer, though, I get:
{
"data": [
]
}
What am I doing wrong? Is there another way to get the comments? There are close to a million so loading them all in the browser and scraping with javascript would be unfeasible.
That is a user profile. You can only get data of a user profile if that specific user authorized your App. In that case, you would need to authorize with the user_posts permission. Just because it is public, does not mean you can get the data - that would only work for Pages.

Graph API Javascript bug

Recently I am experiencing this problem.
When I click to register with facebook and I am logged in as a user, I can see my information correctly. But staying on the same page, if I log out from facebook in some other tab and click Register with facebook on my own site, I see this person profile picture. The url of this image is:
http://graph.facebook.com/undefined/picture?type=large
I am accessing graph API using APP
Kindly advise me the solution to the problem
Accessing a users data requires an access token, with out this token your call is getting undefined returned as a user, and with out the access token appended to the picture url it returns emphamous Unknown User.
refer to: http://developers.facebook.com/docs/facebook-login/access-tokens/
for requesting access tokens, and usage.
Example Only: https://graph.facebook.com/ShawnsSpace/picture?type=large&return_ssl_resources=1&access_token=users_access_token
My script cannot access FB script without Access token
FB.login(function(response)
{
//If the user is succesfully authenticated, we execute some code to handle the freshly
//logged in user, if not, we do nothing
if (response.authResponse)
{
FB.api('/me', function(response) {}
}
{scope:'email,user_events,friends_photos,user_about_me,user_birthday,user_hometown,user_location,user_location,user_relationships'}); });//fbclick
So, I think access token condition is already satisfied.

Getting an Access Token Without User Login in Facebook Graph API?

I am working with facebook graph api rsvp_event. I am using javascript SDK. Everything works great when the user is logged in. But when the user is not logged in, it gives an error.
I need information about who is attending a public event. I now understand that I would need an access token to retrieve this information. So, my question is how do I get the access token if no user is logged in? Is it impossible or is there a workaround? Could it be done server side using app_id and client_secret?
I am developing a ColdFusion page, but I can use PHP if needed. I have support for both.
I have heard the term *offline_access_permission*. They have removed this feature. Could it be done when it was still available?
EDIT:
Could this be achieved by test user? Say, on server side I login via test user, get the event information (Just a "get" request to read who is attending an event) and then log off. On the client side I do the rest ( user login, rsvp to an event).
I don't know much about "test user" or its purpose. Can anyone confirm whether this can be achieved or not?
Thanks in advance.
Are you sure you actually need the user's access token? According to documentation here you may need:
- a generic access_token for public events (those whose privacy is set to OPEN)
- a user access_token for a user who can see the event for non-public events
- an app access_token (for non-public events, must be the app that created the event)
- a page access_token (for non-public events, must be the page that created the event)
You can get info on how to get those tokens here https://developers.facebook.com/docs/concepts/login/access-tokens-and-types/
A good idea could be to store the attending users (in the DB) when you have access to the event - when some user is logged in.
UPDATE for getting the data from FileContent.
I don't know what API response exactly you are referring to, but from my experience they are returning data:
- serialized using JSON - you need to use DeserializeJSON(), for example like this:
local.returnStruct = DeserializeJSON( local.requestResult.FileContent );
or
local.returnStruct = DeserializeJSON( local.requestResult.FileContent.toString() );
send as something similar to URI. I'm using a function to get that data:
function getStructFromQueryString( queryString ) {
var ret = StructNew();
var i = 0;
var key = '';
for(i=1; i LTE ListLen(arguments.queryString,'&'); i++) {
key = ListGetAt(arguments.queryString, i, '&');
ret[ListFirst(key,'=')] = URLDecode(ListLast(key,"="));
}
return ret;
}
Basically what you want is a refresh token that can get access tokens when the user is offline, unfortunately facebook does not provide them anymore as far as i know.
To learn more about oauth2 pleas play around with https://developers.google.com/oauthplayground/ its a very nice tool to understand the oauth2 process.

Why is the Facebook API returning an empty array for albums?

I'm fairly new to the Facebook API, but I've tried to do my due diligence to figure this out, but I can't seem to. I'm simply trying to get a list of the logged-in user's albums, using various techniques, to no avail. I'm using the JavaScript SDK, and I have the following code:
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
FB.init({
appId:'{MY_APP_ID}',
cookie: true,
status: true,
xfbml: true,
oauth : true
});
FB.login(function(response) {
if(response.status === 'connected') {
FB.api('/me/albums', function(response) {
console.log(response);
});
}
}, { scope : 'user_photos' });
</script>
Note that {MY_APP_ID} is actually my application ID. So, when this executes, the popup will request access to the users photos, and that works fine. Now, in code, response returns a data array that contains no elements. In addition to trying the above, I've tried initiating a JSON request to the following URL as well as directly visiting it in the browser:
https://graph.facebook.com/me/albums?access_token=" + response.authResponse.accessToken
And this returns an empty data array as well. The access token that I'm using is coming either from the FB.login method or FB.getLoginStatus. Any help would be greatly appreciated. Thanks in advance.
So, I figured it out, so I will answer my own question. All the other answers on SO was related to permissions, but this wasn't it. It turns out that if I looked at my account settings (I'm the 'user'), and looked at apps, for this application, for some reason, it showed it only was requesting the email address. I knew this wasn't correct, because I was clearly asking for user_photos as well. So, after deleting the application from my profile, and reinitiating the connect, it looks like I'm able to access the albums fine. I'm not sure if Facebook intended to do this by design, but it seems like a potential bug to me.
This can also happen if you're using the JS SDK, as that authentication process and auth dialog are apparently complete separate from what you set up in the developer app.
You need to ALSO include the permissions you desire when you call FB.login() using the optional scope parameter, eg...
FB.login(function(response) {
if (response.authResponse) {
M.FB.setIsAuthorised(true);
// On success.
} else {
// On failure.
}
}, {
scope: 'email,friends_birthday,user_photos,friends_photos,publish_actions'
});
I had a similar issue. Several solutions on stackoverflow mostly attributed the issue to the lack of required permissions. Check the permissions you need by using the Graph API explorer or documentation (The tables have a column called permissions for each field).
Jonathan's solution actually gave me a clue about where I went wrong. I had a different issue where I had double-checked all the permissions set for my app dashboard that were correct, but while logging in, I had specified a scope with a set of permissions which seemed to override the app settings. :( I found this strange, but I rectified it by including the other permissions in the scope too and my problem was resolved.
An effective way to see if the right permissions are being set through the code is to use the following code:
FB.api({ method: 'fql.query', query: 'SELECT user_status,friends_status,user_photos,friends_photos,user_location,friends_location FROM permissions WHERE uid=me()' }, function(resp) {
for(var key in resp[0]) {
if(resp[0][key] === "1")
console.log(key+' is granted');
else
console.log(key+' is not granted');
}
});
P.S: Also make sure that if you changed the permissions in the app dashboard, you log out of your application and login again before testing.
I wasted over 3 hours trying to fix this issue and facebook documentation did not help me a bit, so hope this helps someone!
