Considering a Unity project from ~3 years ago, and using Facebook graph I'm pretty sure it was 1.0,
You could post to a user's wall like this:
private byte[] imageAsBytes;
Texture2D im = ... your image
imageAsBytes = im.EncodeToPNG();
Dictionary<string, object> dct = new Dictionary<string, object>
{
{ "message", "Marketing message here" },
{ "picture", imageAsBytes }
};
Facebook.instance.graphRequest(
"me/photos", HTTPVerb.POST, dct, completionHandler );
As has been made known for many months now, there is a change to this coming.
With Facebook 2.1 being required as of this Aug 8, I'm rather confused about, simply, whether this still works in 2.1?
in short, how to post an image to the user's wall, in 2.1?
Note - here's where to find the important resource CBRoe mentions below...
Note that the only problem with the alternative, FB.FeedShare() is that, as far as I understand, you can not actually post an image (sure, you can link to an image at a URL).
This isn’t deprecated in any way. But since API v2.0 you need to get the necessary permission reviewed and approved by Facebook, before you can ask normal users for it.
And yes, this is a rather major change - but that's why it was announced way ahead of time, via a lot of channels. We all know how fast the IT world moves and changes- so I think you can not put the blame on Facebook here. If you were "out of the game" (this particular one) for over three years, you just have to go and find the resources that a) list what's changed, and b) what the current state of things is. And the developer section does both. The changelog has already been mentioned, and for example the need to get permissions reviewed now is also mentioned on the starting page for Facebook login, right at the top under Essential Guides.
Plus, Facebook actively informs you about changes - if you let them. Go to https://developers.facebook.com/settings/developer/contact/ where you'll find several options to get informed about specific stuff via e-mail.
You can check the changelog to see what changes happened https://developers.facebook.com/docs/apps/changelog. There are no changes for /me/photos as far as I can tell.
It is possible to use image data or a URL.
See https://developers.facebook.com/docs/graph-api/reference/user/photos#Creating for more info

as the title says, I can no longer use friends locations with the graph api explorer any more(in https://developers.facebook.com). Even if I click all access token checkboxes,(trying to get me/friends?fields=locations.fields(place)) I still get error(
{
"error": "Request failed"
}). But me/locations?fields=place works, so it must be someting with "friends" that makes it to crash.
I was able use it 2 weeks ago, and I have not done any changes, it just suddenly stoped working. if I login with my test Account I can get all the parameters I request, but not on my primary account. Is there any one that has any idea what the problem can be? or why it occurred? I have done everything that I can think of, from using diffrent web browers, deleting all history, use diffrent computer. I have compared the settings for both my test account and my main account, both have the same settings.
I am sincerely sorry if i have misspelled anything.
It happens for me as well for any of the locations methods, but the location method with out the s works. I don't know if that data is usable for you.
me/friends?fields=location,hometown
I have figured out the reason to this problem. I has to do with requests from facebook's api, if i lower the Limit per request it works. Then to save the information I use offset.
I have two facebook apps. I am trying to access comments from posts using the graph api. Use an access_token from the old app I can access comments from a non-public post like this:
https://graph.facebook.com/{post-id}/comments?access_token={access-token}
When I do this, I get json for all the comments on the post just as I would expect. But if I use an access token from my new app, when I make the same request I always get an empty data set like this:
{
"data": []
}
If I make a request for a public post using the new app, I get results. It is just the non-public posts that I get the empty dataset. I checked and double-checked all the settings in both my new and old app, and the only difference I could find was that the old app has an alert that I need to fix "July 2013 Breaking Changes".
Could this be what makes the difference? If I mark the old app as being fixed for "July 2013 Breaking Changes" will it stop working correctly too? Where else should I check?
I've been successfully posting from my app to user's walls for a couple of years now using the methodology defined here:
https://developers.facebook.com/docs/reference/api/post/
and now I'm switching to posting video (instead of photos) to their walls and suddenly am getting this error:
{"error":{"message":"(#200) The user hasn't authorized the application to perform this action","type":"OAuthException","code":200}}
Presumably the permissions for posting photos and videos are the same (as far as I can tell) so this is almost certainly a red herring error (not unusual for facebook). So, I'm curious if anyone else uses the /post/ method to publish content to the walls of users who have authorized your apps and I'm wondering what I'm doing wrong... After I pull the user's access token (which I have xxxed out below) the rest of my call looks like this:
post/access_token=xxxxxxxxx
&from=MyCompany
&to=user_facebook_id
&title=SomeString
&link=URL_TO_FOLLOW_BACK_FROM_FB
&source=URL_OF_VIDEO_FILE
&name=SOME_STRING
&type=video
&picture=URL_OF_THUMBNAIL
My guess is that I'm missing something in the call, but I can't figure out what it might be.
I guess this is what is different:
Video POST requests should use graph-video.facebook.com
Source: Graph API > Video
I am trying to publish scores from my app. But unfortunately I am unable to do so. I even tried using the code snippet at http://developers.facebook.com/blog/post/539/ but for some odd reason it didn't work for me. If someone can provide me with some basic guidelines I would really be helpful as that would help me build upon that system and move forward. I don't want any fancy publishing technique I am just looking forward to publishing score at the end of the game.
Using https://graph.facebook.com/user id/scores?score=10&access_token=acess_token returns
{
"data": [
]
}
Your example looks like a HTTP GET request (i.e. 'show me the scores of this user')
To update a score you either need to make a POST request, or 'fake' the POST request by adding ?method=post to your GET call
You'll also need to use an App Access Token, the instructions for obtaining this are at:
https://developers.facebook.com/docs/authentication/#applogin
I've done it using javascript sdk, you can check out the source code for my game
https://apps.facebook.com/tgif-game/
you should be checking out scripts/gameui.js for the calls to posting scores and getting the list of scores.
In the FaceBook Developer Dashboard set your app category as games.
Then only you'll be able to post scores.
I am using Graph API in my application. I am fetching user's facebook wall feeds using graph API also getting details of particular post i.e (Like count,Comments etc).
but i want to allow user to Like and Comment any post from the application itself.
what is the request format for that?
Please help me or give any pointers.

You would be well served to check out the Publishing section of the documentation. It provides information such as this.
One example is liking, which is defined as:
Method: /OBJECT_ID/likes
Description: Like the given object (if it has a /likes connection)
Arguments: none
Basically, just initiate a Graph API call to something like:
[facebookObject requestWithGraphPath:#"98423808305/likes" andDelegate:self];
That will "like" a picture from Coca-Cola (ID taken from the documentation).
Edit 1
According to the documentation:
Most write operations require extended permissions for the active user. See the authentication guide for details on how you can request extended permissions from the user during the authentication step.
Are you sure you have enough privileges? Unfortunately the documentation is very unclear as to whether it serves the dual purpose of liking the object and returning the likes already on that object.
Edit 2
I did some more research into what could be causing this and came across this question and answer that indicated that the code I posted above using requestWithGraphPath:: should work. However, it does not due to a bug on Facebook's Bug Tracker.
Unfortunately, it looks like there is no way to "like" an object via the Graph API, which seems very strange to me. Perhaps it is possible with the legacy REST API instead of the Graph API?
Edit 3
Well, it looks like your best bet is the stream.addLike method of the legacy REST API which you can still call using the Facebook iOS SDK. You should be able to use the stream.addLike method to "like" something in the "stream". Unfortunately, it doesn't appear to support photos, videos, etc. Only posts and comments.
Finally i found the solution for LIKE option
We should use following method for like option.
-(void) requestWithGraphPath:(NSString *)graphPath
andParams:(NSMutableDictionary *)params
andHttpMethod:(NSString *)httpMethod
andDelegate:(id <FBRequestDelegate>)delegate
graphPath = /OBJECT_ID/likes
Paramas = dictionary with comment ,for like option use empty dictionary
HttpMethod should be POST
you should get response = true if the LIKE request is successful.
