I am creating my first facebook app using javascript sdk. In that i can able to post to the user's wall using(FB.api('me/feed', 'post', )).
Now what I need is, when the user accessing my app, it has to show (or list) the post of that user. The code is
FB.api('/me/posts', function(response) {
for (var i=0, l=response.length; i<l; i++) {
var post = response[i];
alert('The value of post is:'+post);
if (post.message) {
alert('Message: ' + post.message);
} else if (post.attachment && post.attachment.name) {
alert('Attachment: ' + post.attachment.name);
}
}
});
But it is not working. If I remove l=response.length and change the condition as i<5 it is going inside the loop but it gives the value of post is undefined.
I didn't get why it is returning as undefined. It returns same for post.message also.
I am getting the access_token of the user also.
If I want to get the post of my user what code i have to use. Can anyone help me in this.
Thanks in advance
You can use the Facebook Graph API Explorer to better understand what data you will be receiving. https://developers.facebook.com/tools/explorer/
You should have l=response.data.length and var post = response.data[i];. Also, some posts will not have a "message", but will have a "story" instead (mainly posts like "Joe Smith and Tom Someone are now friends."). Make sure you also have the appropriate permissions (e.g. user_status) for the information you're trying to receive.

I'm using the Facebook SDK for JS to get a list of FB friends for a given FB user ID. Essentially, I make a request as follows:
FB.api(`/${fbUserId}/friends`, (response) => {
if (response && response.data) {
fbFriends = fbFriends.concat(response.data);
}
if (response && response.paging && response.paging.cursors && response.paging.cursors.after) {
// Recurse through.
}
});
I can get the first set of results, which contains 13 friends, and can also see that there are 200+ friends total, but the problem I'm having is when I try to recurse through and get all 200+ friends.
Specifically, I'm referencing the following two pages:
https://developers.facebook.com/docs/graph-api/using-graph-api/#cursors
https://developers.facebook.com/docs/graph-api/reference/user/friends/
Trying to put things together from those two pages, I thought that a request URL like the following would work:
const afterParam = response.paging.cursors.after ? `&after=${response.paging.cursors.after}` : '';
FB.api(`/${fbUserId}/friends${afterParam}`, (response) => {
...
But it doesn't return any results. I am console-logging response.paging.cursors.after, and I'm sure it's set appropriately from the first API call, but it's not returning any more friends. I always get back an empty array for response.data.
What am I doing wrong? Admittedly, the FB API docs seem a bit sparse, and I don't see anywhere where they specifically show how to go through pages of results for the friends API endpoint, but I'm obviously missing something. Thank you.
I have a fan page with an address.
Also, I can get the location details using the facebook API.
However, to create a new post with a review button I need the location id instead of the details.
I am using the following lines to create a share button:
var data = {
message: 'Hi !',
place: location_id
};
FB.api('/me/feed', 'post', data, function(response) {
if (!response || response.error) {
console.error(response.error);
} else {
console.log(response.id);
}
});
And it works if I use a specific location id. But I can't get the location id from a specific page.
Please give me some ideas. Thank you!
I was falling asleep, but I got one idea.
And finally, that idea was the solution:
It is possible to use the fan page id directly in the place parameter. It can be used like a place id.
I have seen this question but what I want is different.
I want to get the Facebook ID not from a general URL (and therefore conditional if it has Like button or not). I want to get the Facebook ID given a Facebook page using the Graph API.
Notice that Facebook pages can have several formats, such as:
http://www.facebook.com/my_page_name
http://www.facebook.com/pages/my_page_name
http://www.facebook.com/my_page_ID
I know I could do some regex to get either the my_page name or my_page_ID, but I am wondering if any one know if GraphAPI is supporting what I want.
It seems to me that the easiest solution to what you describe is to just get the id/name from the url you have using lastIndexOf("/") (which most languages have an equivalent for) and then get "https://graph.facebook.com/" + id.
The data that this url returns has the id (i.e.: 6708787004) and the username (i.e.: southpark), so regardless of which identifier you use (what you extract from the url using lastIndexOf), you should get the same result.
Edit
This code:
identifier = url.substring(url.lastIndexOf("/"))
graphUrl = "https://graph.facebook.com/" + identifier
urlJsonData = getGraphData(graphUrl)
Should work the same (that is result with the same data) for both:
url = http://www.facebook.com/southpark
And
url = http://www.facebook.com/6708787004
(you'll obviously need to implement the getGraphData method).
Also, the 2nd url form in the question is not a valid url for pages, at least not from my tests, I get:
You may have clicked an expired link or mistyped the address. Some web
addresses are case sensitive.
The answer to the question is posted above but the method shown below works fine we do not have to perform the regex on the facebook page urls
I got the answer by this method
FB.api('/any_fb_page_url', function(response){
console.log(response);
});
any_fb_page_url can be any of the following types
https://www.facebook.com/my_page_name
https://www.facebook.com/pages/my_page_name
https://www.facebook.com/my_page_ID
This are also listed in question above
This code is tested on JS console available on Facebook Developers site tools
You can get the page id by using the below api
https://graph.facebook.com/v2.7/smhackapp?fields=id,name,fan_count,picture,is_verified&access_token=access_token&format=json

This answer is updated and checked in 2019:
and it is very simple because you do not need to extract anything from the link. for examples:
https://www.facebook.com/pg/Vaireo-Shop-2138395226250622/about/
https://www.facebook.com/withminta
https://www.facebook.com/2138395226250622
https://graph.facebook.com/?id=link&access_token=xxxxxxxx
response:
{
"name": "Vaireo Shop",
"id": "2138395226250622"
}
full nodeJS answer:
async function getBusinessFromFBByPageURL(pageURL: string) {
const accessToken = process.env.fb_app_access_token;
const graphUrl = `https://graph.facebook.com/?id=${pageURL}? access_token=${accessToken}`;
const fbGraphResponse = await Axios.get(graphUrl);
<?php
function getFacebookId($url) {
$id = substr(strrchr($url,'/'),1);
$json = file_get_contents('http://graph.facebook.com/'.$id);
$json = json_decode($json);
return $json->id;
}
echo getFacebookId($_GET['url']);
?>
Thats a PHP example of how to get the ID.
As of Nov 26 2021 none of these solutions work.
Facebook has locked down the API so you need an App Review.
https://developers.facebook.com/docs/pages/overview/permissions-features#features
This answer takes into account that a URL can end with a trailing slash, something that Facebook event pages seem to have in their URLs now.
function getId(url) {
var path = new URL(url).pathname;
var parts = path.split('/');
parts = parts.filter(function(part) {
return part.length !== 0;
});
return parts[parts.length - 1];
}
You can Use Requests and re Modules in python
Code:
import requests,re
profile_url = "https://www.facebook.com/alanwalker97"
idre = re.complie('"entity_id":"([0-9]+)"')
con = requests.get(profile_url).content
id = idre.findall(con)
print("\n[*] ID: "+id[0])
Output:
[*] ID: 100001013078780
Perhaps you can look through the https://developers.facebook.com/docs/reference/api/#searching docs: search against a couple of types and if you find what you're looking for go from there.
I'm absolutely new to programming and just managed to learn the basics of ActionScript 3. Now, I would like to learn how to post on my Friends' Walls via the as3 SDK using the UI class (taken from a nice Tutorial):
This is how I post on my own Wall:
protected function newsFeed ():void
{
// define your caption text
var theCaption:String = "CaptionText";
// define the descrition text
var theDescription:String = "Text for game Achievement";
// We need to follow the FB docs to tell it what sort of input we are sending to FB
// We are trying to set the 'feed'
var methodInput:String = 'feed';
var thePicture:String = "mylink/picture.png";
var theLink:String = "mylink";
var theName:String = "Name of FB Status Setter";
// Create an object that we'll call 'data' and fill it with the actual data we're sending to Facebook
var data:Object = {
caption:theCaption,
description:theDescription,
picture:thePicture,
name:theName,
link:theLink
};
Facebook.ui(methodInput, data, onUICallback);
}
protected function onUICallback(result:Object):void
{
// do something
}
This works perfectly fine. I know that I have to integrate the parameter "to" somewhere. But I don't know where and how. Sorry I'm very very new to this. This is from Facebook Docs
Properties
from: The ID or username of the user posting the message. If this is unspecified, it defaults to the current user. If specified, it must be the ID of the user or of a page >that the user administers.
to: The ID or username of the profile that this story will be published to. If this >is unspecified, it defaults to the the value of from.
Hopefully someone can help me out.
Best Regards,
Amir
P.S.: Is there a way to post only one friend's wall and another way to post on several friends' walls?
I believe you want to use Facebook.api() rather than 'ui'. According to the documentation for the AS3 FB API, 'ui' just opens the share dialog. If you want to create a post on a friends wall, then you'll want to use 'api'.
I haven't tested this in Flash, but I think you can set the method as /PROFILE_ID/feed ... of course replacing "PROFILE_ID" with the FB uid of the friend. Then, include the arguments; message, picture, link, name, caption, description and source in your data object.
So your code would look something like:
var method:String = "/friend_id/feed";
var data:Object = {};
data.message = "Your message";
data.picture = "http://www.google.com/kittens.jpg";
data.link = "http://www.mysite.com/link";
data.caption = "Your caption";
data.description = "Your description";
data.source = "http://www.mysite.com/video.swf";//(optional) source is a video or Flash SWF
Facebook.api(method, yourCallback, data, "POST");
function yourCallback(result:Object, fail:Object):void {
if (result) {
trace(result)
} else if (fail) {
trace(fail);
}
}
If you have multiple friends, you could probably just put the uid's in an array and loop through the method above. The AS3 API has a batch request method that I haven't tried, but you can check out the Documentation.
Facebook has some pretty helpful tools that are somewhat hidden.
Checkout their Debugger and their Graph API Explorer
Hope that's helpful.
I tried to get Facebook comments using:
http://graph.facebook.com/[post_id]/comments
It results only 2 of 15 comments, and without count info.
{
"data": [
{
"id": "[post_id]",
"from": {
"name": "[name]",
"id": "[id]"
},
"message": "[message]",
"created_time": "2011-01-23T02:36:23+0000"
},
{
"id": "[id]",
"from": {
"name": "[name]",
"id": "[id]"
},
"message": "[message]",
"created_time": "2011-01-23T05:16:56+0000"
}
]
}
Anyone know why only 2 comments?
Also, I want to retrieve comments (default number) or retrieve comments with my limit number, and get its comments count. Any idea? (Please use Graph API).
You need to call it from a secure request https and provide an access_token:
https://graph.facebook.com/19292868552_118464504835613/comments?access_token=XXX
EDIT:
Added the object from the post document. try clicking the comments connection and then remove the access_token and try and see the difference.
In order to get the Like count and the comment count then you need to use a combination of the PostOwnerID and PostID not just the PostID
So for your example it would be:
https://graph.facebook.com/153125724720582_184234384932460/comments
Again, as mentioned in some of the other answers you need to use the https method along with an auth_token
I experienced the same problem with comments. The issue was that I was using an access token for a test user. Because test users don't have access to other FB users information, only the comments from pages were shown.
There is a word JUGAAR in Urdu that means, finding a way out, just to get the job done. So for like purpose I made this JUGAAR, I hope it helps.
$contents = file_get_contents("http://graph.facebook.com/" . $_GET['id'] . "/likes");
if (substr_count($contents, 'name')>0) {
echo substr_count($contents, 'name') . " people like this album";
}
By the way I am also new to this Fb stuff, I am looking for help to post comments. When I try to use graph.api./id/comments?access_token=sdfsfsdf&message="D" it still returns comments for the id instead of posting.
As a sanity check, do you have "read_stream" permission? I can see the full comments with my access token that uses "read_stream". As mentioned by other people, you have to use https and access token as well...
Try to authenticate via App Login (http://developers.facebook.com/docs/authentication) and then to call GraphAPI with access_token prarameter.
You can do something like this to avoid the whole count of comments issues:
Get the object's (a post is considered an object in the Graph API) ID-as I understand from your question, you already have it?
Create a Comments Social Plugin with this ID, and get the code for it.
Embed the code in your site.
This will result in all the comments for this object.
To get the count of comments per object, you can execute an fql query, something like this:
SELECT comments FROM stream WHERE post_id = [yourpostid]
This will return in the comments array under the count parameter the number of counts for this object.
SELECT comments FROM stream WHERE post_id = [yourpostid] shall not work in this case ..
the id which is returned after making a graph call successfully to post on a user's wall (using access_token of an application ) is of the form abcdef_qwerty ( underscore seperated id )
where as the post id which is mapped in the post_id of the comments table is of the form "lmnop" ..
to get the counts of like and comments on this post id of form "abcdef_qwerty" making a graph call withh app generated access token seems to be the only solution ..
something like:
https://graph.facebook.com/100002619172565_117323155031656?access_token=xxxxxxxxxxxxx
After Successfully Login call this method facebookComments()
parameters.putString("fields", "message"); .............// Its Important
AccessToken accessToken = AccessToken.getCurrentAccessToken();
public void facebookComments() {
try {
getFriends(accessToken, new GraphRequest.Callback() {
public void onCompleted(GraphResponse response) {
Log.e("keshav", "one" + response);
CommonMethod.showAlert("res --> " + response, MainActivity.this);
}
}
);
} catch (Exception e) {
CommonMethod.showAlert("Exception is -> " + e, MainActivity.this);
}
}
public void getFriends(AccessToken token, GraphRequest.Callback callback)
{
// TODO Comments Working but id return only
GraphRequest requestt = new GraphRequest(token, "744511125731315_751199848395776/comments",
null, HttpMethod.GET, callback);
Bundle parameters = new Bundle();
parameters.putString("fields", "id"); // todo in use imp
parameters.putString("fields", "name"); // todo in use imp
parameters.putString("fields", "from"); // todo in use imp
parameters.putString("fields", "message"); // todo in use imp
requestt.setParameters(parameters);
requestt.executeAsync();
}
It results only 2 of 15 comments
Add a limit parameter to the URL:
http://graph.facebook.com/[post_id]/comments?limit=1000&access_token=XXX
This should show all the comments.
