How can I retrieve this photo through graph API?
It is not possible to get photos posted to the wall of an event like your sample.
I had a client last summer who started a contest that had people post photos to an event wall. They asked me to get them for display on their website. We had to manually download them to get them.
You can look at the feed for that event using
/412778502140672/event?fields=feed
But there are no attachments, and no connections. I don't believe it is possible to even get an event's stream using FQL.
If you are working on Android then this way can help you
Request r=Request.newMeRequest(session, new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user, Response response) {
// TODO Auto-generated method stub
JSONObject jso=null;
try{
//Parse json here
}
catch ( Exception e)
{
//Log.d(sTag,e.getMessage());
}
}
});
Bundle paramsPics=r.getParameters();
paramsPics.putString("fields",
"photos");
r.setParameters(paramsPics);
Response response=r.executeAndWait();
In the "me/home" API call, an item that has a photo will have a "picture" field with the source URL for a low resolution picture. To get to original high resolution picture, and dimensional variants of it, you have to do another API call using the "object_id" field in the same JSONObject as the "picture" field.
Doing the graph call for the "object_id" will then give you a "source" field with the original source image URL, as well as an array of different image sizes.
EDIT:
Set the graph path to "412778502140672_425592530859269" for the post.
Set the graph path to "482760011786004" for the photo.

Our organization wants to develop a "LOST & FOUND System Application" using chatbot integrated in a website.
Whenever the user starts the conversation with the chatbot, the chatbot should ask the details of lost item or item found and it should store the details in database.
How can we do it ?
And can we use our own web-service because organization doesn't want to keep the database in Amazon's Server.
As someone who just implemented this very same situation (with a lot of help from #Sid8491), I can give some insight on how I managed it.
Note, I'm using C# because that's what the company I work for uses.
First, the bot requires input from the user to decide what intent is being called. For this, I implemented a PostText call to the Lex API.
PostTextRequest lexTextRequest = new PostTextRequest()
{
BotName = botName,
BotAlias = botAlias,
UserId = sessionId,
InputText = messageToSend
};
try
{
lexTextResponse = await awsLexClient.PostTextAsync(lexTextRequest);
}
catch (Exception ex)
{
throw new BadRequestException(ex);
}
Please note that this requires you to have created a Cognito Object to authenticate your AmazonLexClient (as shown below):
protected void InitLexService()
{
//Grab region for Lex Bot services
Amazon.RegionEndpoint svcRegionEndpoint = Amazon.RegionEndpoint.USEast1;
//Get credentials from Cognito
awsCredentials = new CognitoAWSCredentials(
poolId, // Identity pool ID
svcRegionEndpoint); // Region
//Instantiate Lex Client with Region
awsLexClient = new AmazonLexClient(awsCredentials, svcRegionEndpoint);
}
After we get the response from the bot, we use a simple switch case to correctly identify the method we need to call for our web application to run. The entire process is handled by our web application, and we use Lex only to identify the user's request and slot values.
//Call Amazon Lex with Text, capture response
var lexResponse = await awsLexSvc.SendTextMsgToLex(userMessage, sessionID);
//Extract intent and slot values from LexResponse
string intent = lexResponse.IntentName;
var slots = lexResponse.Slots;
//Use LexResponse's Intent to call the appropriate method
switch (intent)
{
case: /*Your intent name*/:
/*Call appropriate method*/;
break;
}
After that, it is just a matter of displaying the result to the user. Do let me know if you need more clarification!
UPDATE:
An example implementation of the slots data to write to SQL (again in C#) would look like this:
case "LostItem":
message = "Please fill the following form with the details of the item you lost.";
LostItem();
break;
This would then take you to the LostItem() method which you can use to fill up a form.
public void LostItem()
{
string itemName = string.Empty;
itemName = //Get from user
//repeat with whatever else you need for a complete item object
//Implement a SQL call to a stored procedure that inserts the object into your database.
//You can do a similar call to the database to retrieve an object as well
}
That should point you in the right direction hopefully. Google is your best friend if you need help with SQL stored procedures. Hopefully this helped!
Yes its possible.
You can send the requests to Lex from your website which will extract Intents and Entities.
Once you get these, you can write backend code in any language of your choice and use any DB you want.
In your use case, you might just want to use Lex. PostText will be main function you will be calling.
You will need to create an intent in Lex which will have multiple slots LosingDate, LosingPlace or whatever you want, then it will be able to get all these information from the user and pass it to your web application.
I am trying to get friend list from facebook on cocos2dx game. But when I try, only available to get 25 friends. But in Facebook Graph API Test Site on facebook developer site, I can get more with limit paramter like the picture as below.
How can I implement this on Cocos2dx? The current codes are like this.
void Facebook::getFBFriends()
{
if(fb_user_id.empty() == true) return;
g_vFBFriends.clear();
std::string path = "/me";
FacebookAgent::FBInfo params;
params.insert(std::make_pair("fields", "invitable_friends"));
FacebookAgent::getInstance()->api(path, FacebookAgent::HttpMethod::Get, params, CC_CALLBACK_2(Facebook::onGetFriendsDone, this));
}
"Paging" is the keyword. Without the limit parameter, you only get the first 25 entries - and a link to get the next 25 in the JSON result.

I have just started trying to use ember-data. I have an ember app for which I need to produce all the data on the client side and then save it all at once. So my object graph has a "Project" as the root object, then a project can have many "Sections" and then each section can have many "Items".
I am up to the stage where I am trying to create Item records on the client side and add them to the correct Section. When I am ready to save the data I just want to use project.save() and have it go and save the object graph instead of saving every time the model changes.
I am trying to look up the section to place the items in by name using store.filter({name:"section1"}) but ember keeps trying to go to the server to look them up. I see this in the console: GET http://localhost:4200/sections?name=Section1 404 (Not Found).
This is what I am trying to do:
store.filter('section', {name:'Section1'}, function(section) {
return section;
}).then(function(section)
{
var record;
//create a record
section.pushObject(record);
});
You are doing server side filtering and you want client side filtering.
Please read this article carefully.
In short, you should do
store.filter('section', function(section) {
return section.get('name') == 'Section1';
});
I am trying to integrate facebook sdk in my unity android game. I can not find FBUtil and GameStateManager in SDK downloaded from developer site.
I got the userId using FB.UserId. Also got the response
"sending to Unity OnInitComplete({"access_token":"CAAUCMHNGlZCcBAHJBQAs7AoJNevkZAFbkpSRk60TURemvv4Y6IOu9NXjGcFjFRZAx9RoxwKT4ZBZASs0NLiYTmi4rl7RyWYdtxxhlKkSjoIWiqqDSBdSDKk0OppB2ZB4U6IgtqQs9PM8uNCaNF5xgqWn2c9DDkp4dJc9p38XONKpdwRF7qDHtM","user_id":"100003735696788","opened":true})"
Just after that when I tried to get profile picture of the user, using the code given on developer.facebook.com,
void LoginCallback() {
FB.API (
"/me/picture",
Facebook.HttpMethod.GET,
APICallback
);
}
The response I get is 4 question marks.
????
where is the problem? Please help..
I used this link using WWW in Unity and it worked well.. This is exactly what I did
Once you have the user id, create a WWW object like this:
WWW url = new WWW("http://graph.facebook.com/INSERT_USER_ID_HERE/picture?type=large");
Then in the LateUpdate I put an IF condition checking if the picture was loaded or not with a bool called loaded to avoid reloading the picture more than once
if (url.isDone && !loaded)
{
loaded = true;
Texture2D textFb2 = new Texture2D(50, 50, TextureFormat.ARGB32, false); //TextureFormat must be DXT5
url.LoadImageIntoTexture(textFb2);
PLANE_OR_QUAD_OBJECT.renderer.material.mainTexture = textFb2;
}
NOTE: url is visible in the whole class as well as loaded
If you need further help with this, let me know!
Normally Facebook picture API should return data with Texture type NOT text
For example, If you use code like #jkgm777 answer,
WWW url = new WWW("http://graph.facebook.com/INSERT_USER_ID_HERE/picture");
You should get Texture type that can use to replace your texture object in scene.
But If you want to get image url, USE THIS
http://graph.facebook.com/INSERT_USER_ID_HERE/picture?redirect=false
You will get this JSON for response
data: {
url: "{#IMAGE_URL#}",
is_silhouette: false
}
I'm submitting an object to our API via a POST and then transitioning to a route that displays that object. The API modifies one or more fields in the object in the POST and returns the updated info in the request response.
The data displayed is the original data from before the POST to our API. I can see from the console that ember-data is receiving back the updated information from our API. How can I force ember to "refresh" the object so that it displays the correct info?
Matt. Yehuda Katz posted a reply to a user which provides this functionality:
https://stackoverflow.com/a/14183507/506230
Basically you create a record, apply it, save it, then reload it.
saveMessage: function(text){
var acct = Social.Account.find(this.get("id")),
msg = Social.store.createRecord(
Social.Message,
{
text: text,
account: acct,
created: new Date()
}
);
acct.get("messages").addObject(msg);
Social.store.commit();
var timeoutID = window.setTimeout(function(){
__msg.reload();__
console.log('reloading');
}, 250);
}
It turns out ember was actually behaving properly and no additional work was necessary. The problem is that I was setting a variable on the controller with the same name as a computed property on my model. The value of the variable on the controller was being displayed rather than the computed property. Changing the name of the controller variable resolved the issue without any additional code.
