I'm doing a FB app with the Graph API in Flash. I've got everything working which consists in uploading some images created by the user in the app. The only part that I'm missing is how to tag these photos as with the Graph API it is not possible.
So I was wondering if it's possible to call a method of the REST API even though I'm using the Graph API.
Any suggestion on how to deal with that?
Thanks
This question was asked a long time ago but no answers for when I was looking so here's the answer. (Hint: it's all about the formatting of the JSON string within the param object being passed to the Graph API)
function postPhoto( e:MouseEvent ) : void
{
var bitmapData:BitmapData = new BitmapData( 600, 600 );
bitmapData.draw( someSprite );
var bitmap:Bitmap = new Bitmap( bitmapData );
var params:Object = { image:bitmap, message:'Message', fileName:'file-name', tags:'[{"tag_uid":"12345678","x":"0","y":"0"}]' };
FacebookDesktop.api( 'me/photos', photoPostComplete, params );
}
function photoPostComplete( result:Object, fail:Object ) : void
{
//do callback type of stuff
}

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 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.
Currently I'm working on my HTML 5 ASP.Net Application,
Which has requirement of Graffiti Wall, When user draw something on my Wall(means on my HTML 5 Canvas element), and Press Share Button on my Page, at that time the whole picture should need to be post on one of the Facebook Page.
Now my question is that is this thing possible using C# facebook sdk by codeplex ?
if its possible, than how to post image on facebook fan page using this SDK??
Where can I get the good resource the implement this kind of functionality or similar code.
I've check the all examples given by them, there is no any example which post on the facebook fan page.
Or even other library that can implement this kind of functionality.
I've check this library, and see that it has FacebookClient,ExpandoObject, FacebookMediaObject kind of classes, but how to and where to use this classes,where are the description and sample code.
Thanks,
Jigar Shah
you can post to others wall using "{id}/feed"
if you want to post image/video on wall. Try downloading the samples from nuget.
Install-Package Facebook.Sample
Here is how to do using the graph api.
public static string UploadPictureToWall(string id, string accessToken, string filePath)
{
var mediaObject = new FacebookMediaObject
{
FileName = System.IO.Path.GetFileName(filePath),
ContentType = "image/jpeg"
};
mediaObject.SetValue(System.IO.File.ReadAllBytes(filePath));
try
{
var fb = new FacebookClient(accessToken);
var result = (IDictionary<string, object>)fb.Post(id + "/photos", new Dictionary<string, object>
{
{ "source", mediaObject },
{ "message","photo" }
});
var postId = (string)result["id"];
Console.WriteLine("Post Id: {0}", postId);
// Note: This json result is not the orginal json string as returned by Facebook.
Console.WriteLine("Json: {0}", result.ToString());
return postId;
}
catch (FacebookApiException ex)
{
// Note: make sure to handle this exception.
throw;
}
}
I am building a REST API for my project. The API for getting a given user's INFO is:
api.com/users/[USER-ID]
I would like to also allow the client to pass in a list of user IDs. How can I construct the API so that it is RESTful and takes in a list of user ID's?
If you are passing all your parameters on the URL, then probably comma separated values would be the best choice. Then you would have an URL template like the following:
api.com/users?id=id1,id2,id3,id4,id5
api.com/users?id=id1,id2,id3,id4,id5
api.com/users?ids[]=id1&ids[]=id2&ids[]=id3&ids[]=id4&ids[]=id5
IMO, above calls does not looks RESTful, however these are quick and efficient workaround (y). But length of the URL is limited by webserver, eg tomcat.
RESTful attempt:
POST http://example.com/api/batchtask
[
{
method : "GET",
headers : [..],
url : "/users/id1"
},
{
method : "GET",
headers : [..],
url : "/users/id2"
}
]
Server will reply URI of newly created batchtask resource.
201 Created
Location: "http://example.com/api/batchtask/1254"
Now client can fetch batch response or task progress by polling
GET http://example.com/api/batchtask/1254
This is how others attempted to solve this issue:

I find another way of doing the same thing by using #PathParam. Here is the code sample.
#GET
#Path("data/xml/{Ids}")
#Produces("application/xml")
public Object getData(#PathParam("zrssIds") String Ids)
{
System.out.println("zrssIds = " + Ids);
//Here you need to use String tokenizer to make the array from the string.
}
Call the service by using following url.
http://localhost:8080/MyServices/resources/cm/data/xml/12,13,56,76
where
http://localhost:8080/[War File Name]/[Servlet Mapping]/[Class Path]/data/xml/12,13,56,76
As much as I prefer this approach:-
api.com/users?id=id1,id2,id3,id4,id5
The correct way is
api.com/users?ids[]=id1&ids[]=id2&ids[]=id3&ids[]=id4&ids[]=id5
or
api.com/users?ids=id1&ids=id2&ids=id3&ids=id4&ids=id5
This is how rack does it. This is how php does it. This is how node does it as well...
There seems to be a few ways to achieve this. I'd like to offer how I solve it:
GET /users/<id>[,id,...]
It does have limitation on the amount of ids that can be specified because of URI-length limits - which I find a good thing as to avoid abuse of the endpoint.
I prefer to use path parameters for IDs and keep querystring params dedicated to filters. It maintains RESTful-ness by ensuring the document responding at the URI can still be considered a resource and could still be cached (although there are some hoops to jump to cache it effectively).
I'm interested in comments in my hunt for the ideal solution to this form :)
You can build a Rest API or a restful project using ASP.NET MVC and return data as a JSON.
An example controller function would be:
public JsonpResult GetUsers(string userIds)
{
var values = JsonConvert.DeserializeObject<List<int>>(userIds);
var users = _userRepository.GetAllUsersByIds(userIds);
var collection = users.Select(user => new { id = user.Id, fullname = user.FirstName +" "+ user.LastName });
var result = new { users = collection };
return this.Jsonp(result);
}
public IQueryable<User> GetAllUsersByIds(List<int> ids)
{
return _db.Users.Where(c=> ids.Contains(c.Id));
}
Then you just call the GetUsers function via a regular AJAX function supplying the array of Ids(in this case I am using jQuery stringify to send the array as string and dematerialize it back in the controller but you can just send the array of ints and receive it as an array of int's in the controller). I've build an entire Restful API using ASP.NET MVC that returns the data as cross domain json and that can be used from any app. That of course if you can use ASP.NET MVC.
function GetUsers()
{
var link = '<%= ResolveUrl("~")%>users?callback=?';
var userIds = [];
$('#multiselect :selected').each(function (i, selected) {
userIds[i] = $(selected).val();
});
$.ajax({
url: link,
traditional: true,
data: { 'userIds': JSON.stringify(userIds) },
dataType: "jsonp",
jsonpCallback: "refreshUsers"
});
}
