I use the url https://graph.facebook.com/{app_user_id}/picture?width=120&height=120 to show the user picture on my app, but since this morning, it has stopped working on mobile devices.
Now, the same url redirects to https://lookaside.facebook.com/platform/profilepic/?asid={app_user_id}&height=120&width=120. This url works on desktop web, but on mobile it redirects again to https://m.facebook.com/platform/profilepic/?asid={app_user_id}&height=120&width=120 and the mobile web refuses to output the image. If I try to load it in the address bar, it is downloaded instead of showed.
I have searched for any change on the Facebook graph api about this but didn't find anything. Any hint to solve this? Thanks.
This seems to be a bug. Started happening to my app earlier on this morning. Still no fix as of yet.
A few bug reports that have been submitted on Facebook for Developers:
Profile Pictures Can't Load
Graph API Profile picture doesn`t work on mobile
Cross site policy error while accessing graph pictures
I faced the same issue today and I'v found a solution for that and it worked for me.
After login we get below Profile pic URL
http://graph.facebook.com/11111111111/picture?type=large&height=320&width=420
11111111111 is your social id/facebook id
now we need to change this URL in order to display image,
here is the code.
try {
profile_pic = new URL("https://graph.facebook.com/" + id + "/picture?type=large");
Log.i("profile_pic", profile_pic + "");
Picasso.with(getContext()).
load(profile_pic.toString())
.placeholder(R.drawable.img)
.into(imageviewId);
}
catch (MalformedURLException e) {
e.printStackTrace();
}
id is your socialid/facebook id
in short we just need to remove &height=320&width=420 from url.
you can compare both the url:
http://graph.facebook.com/11111111111/picture?type=large&height=320&width=420
https://graph.facebook.com/11111111111/picture?type=large
and yes you need to change http to https as well
Though I didn't find any official announcements, Facebook during last few days changed their api's, now when you request user's public profile the picture url has extra parameters, ext and hash
Calling the url without these params returns 404 error.
Not sure if the change is affecting Page Scope ID's only.
Currently, when you request user's public profile data the url looks like this
https://lookaside.facebook.com/platform/profilepic/?psid=PAGE_SCOPED_ID&height=1024&ext=1522585606&hash=AeThc8c7EQDFgShs
before it was just
https://lookaside.facebook.com/platform/profilepic/?psid=PAGE_SCOPED_ID&height=1024
It seems to me the only known solution currently would be requesting new public profile data and updating your database.
Hope that helps.

I have 3 questions: 1)Can I combine facebook login via mozila browser(selenium) with facebook graph api, for example:
browser=webdriver.Firefox()
browser.get('https://facebook.com')
user=browser.find_element_by_id('email')
user.send_keys('email')
password=browser.find_element_by_id('pass')
password.send_keys('pass')
login=browser.find_element_by_id('u_0_r')
login.click()
graph = facebook.GraphAPI(token)
profile = graph.get_object("me")
friends = graph.get_connections("me", "friends")
friend_list = [friend['name'] for friend in friends['data']]
print (friend_list)
2)Can somebody help me with login on facebook through app_id, secret_id and token, or through email and password
3)I want to get profile info, for example with help of get_object, but I need to know user's id to do it. How can I get this id, if I have only page url's, or I can use part after facebook.com/ to do this request?
P.s. If u know answer at least on one of this questions, pls right it in comments or in answers, it will be very useful:)
We have used the v2.0 graph API & FQL(FaceBook Query Language) for getting the FaceBook details in our project. But recently the result is empty.
I have checked the developer.facebook.com and i found one solution that is Login Review process. We need to get the FB details means we need to get the pre approval from FB.(user_photos, user_videos) It'll work perfectly or not ?
https://developers.facebook.com/blog/post/2015/04/28/april-30-migration/
Sample Code :
args = "SELECT uid,name FROM user WHERE uid = me()"
file = urllib2.urlopen("https://api.facebook.com/method/fql.query?" + urllib.urlencode(args), timeout=3)
Please give some suggestion to fix this problem.
https://developers.facebook.com/docs/apps/api-v1-deprecation
Advance Thanks :)
Have a look at
https://developers.facebook.com/docs/apps/changelog#v2_1_deprecations
The FQL and REST APIs are no longer available in v2.1: Previously announced with v2.0, apps must migrate to versioned Graph API calls starting with v2.1.
You're querying the REST API which is deprecated, as cited. Use https://graph.facebook.com/fql instead.
I have some code like the following in my application:
message = "Hi, #John Doe!"
postID = fb.stream.publish(
message = loader.render_to_string('wall_post.phtml', {'message':message}),
action_links = simplejson.dumps([{'text': "Check out blah", 'href': "http://blah.dev"}]),
target_id = 'nf'
)
Is there any way to represent a facebook #mention in the message string so that facebook converts it to a profile link for the mentioned user?
I've also been looking for an answer to this. The facebook website uses the format:
#[139730900025:PhotoGrabber] is awesome
to represent the links but I haven't been able to make that work. I re-posted a thread on the facebook forum under the "Stream" category since your post wasn't getting any attention:
http://forum.developers.facebook.com/viewtopic.php?id=47885
Mention it's partially available by open graph now. You can use only when posting an open graph ACTION
Check:
https://developers.facebook.com/docs/opengraph/mention_tagging/
It seems still impossible to use #mention tagging in classic feed posting via API
I'm pretty sure this is impossible at the moment. If it were posible by using the format that tam7t suggested it should work... Your best bet is asking them to add that to their api stream parser.
This is not possible at the moment, sorry.
AFAIK facebook's API does not allow this. The only approach that I know of at the moment would be to write a screen scraper to do these posts using the format described by tam7t's answer. If you use the mobile version of facebook's site (m.facebook.com) it makes it much easier.
NOTE: This might be a violation of Facebook's Application TOS.
Edit:
Here is some ruby code that will do the trick, using the Mechanize Gem
require 'mechanize'
agent = Mechanize.new
agent.user_agent_alias = 'Mac Safari'
page = agent.get('http://m.facebook.com')
form = page.forms.first
# enter credentials
form.pass = 'user password'
form.email = 'user#example.com'
page = agent.submit form
# go straight to page to post on
page = agent.get("http://m.facebook.com/wall.php?id=PAGE_ID_NUM")
form = page.forms.first
form.message = "#[139730900025:PhotoGrabber] is awesome"
page = agent.submit form
NOTE: Obviously (as tiagoboldt kindly pointed out) it would be wrong to store / utilise the credentials of other people in your application. This approach would only be appropriate for making posts from a facebook account that you controlled.
That said, back to the original question of putting an #mention in a wall post, I have noticed that whilst the post and #mention go up on the wall fine, this method does not propagate the post to the mentioned user/page's wall. Not sure if that is important to you.
