I am currently trying to run through the publish open graph story for iOS tutorial on the Facebook website.
https://developers.facebook.com/docs/tutorials/ios-sdk-tutorial/publish-open-graph-story/
I'm getting lost at step 2 - Set up your back end server. I have set up a Heroku account just like it says and I go through the set up tutorial on the Heroku site. It all seems fine. I save the code listed in step 2 in a new file I created called opengraphobject.php (I have no idea if this was the right thing to do?).
After that it says "Once you've uploaded the dynamic object creation code, test a sample object using the Object Debugger. Enter a URL into the debugger, for example:"
https://fbsdkog.herokuapp.com/repeater.php?fb:app_id=233936543368280
&og:type=fb_sample_scrumps:meal
&og:title=Pizza
&og:description="Pizza"
&og:image=https%3A%2F%2Fs-static.ak.fbcdn.net%2Fimages%2Fdevsite%2Fattachment_blank.png
&body=Pizza
I have no idea what I'm supposed to do at this point. My action is called beats and the object is called boss. How do I generate a url like this for my own action?
I can't move onto stop 3 till I move past this because it's very similar.
The page opengraphobject.php should contain the sample code provided in that step.
So when you are done setting it up you point to your url in the debugger to test
https://YOUR.herokuapp.com/opengraphobject.php?fb:app_id=YOUR_APP_ID
&og:type=fb_sample_scrumps:meal
&og:title=Pizza
&og:description="Pizza"

Im developing an app with ionic framework and im using Backand as BaaS, im using the sign in with social accounts service that provides me, but when im trying to sign in with facebook, return this error.
The user is not signed up to 'name-of-my-app'.(signing in with facebook).
And when im trying to sign in with google, return this error:
Object reference is not set to an instance of an object.
Also im create my own apps in facebook and google and i set the AppId and AppSecret to Backand.
I dont know why im receiving this error, actually im ussing almost the same code that the starter's Backand provides.
I have met this kind of error "Object reference is not set to an instance of an object" too, after pressing "Validate & Update" button, after editing database json model several times in the backand control panel. I could save the new model and continue, but that red error was appearing on top right at each save. My hypothesis is that also in your case the issue is related to a bug in the database model editor. I personally got rid of that kind of error by deleting the project (I had no data in it yet) and creating a new one, re-pasting and saving all at once the exact same database model json I created in the previous project.
So, I wanted to create a new social media app using Swift and Parse. When I go to the Parse site, and click on dashboard, it gives me a login screen. I don't have an account, so I click on the "I don't have a parse account" button. When I click on that, it just takes me back to the home page. I did manage to get the code and frameworks and stuff that I needed from the docs, but that didn't quite work. It gave me this for the initialize code:
let configuration = ParseClientConfiguration {
$0.applicationId = "YOUR_APP_ID"
$0.server = "http://YOUR_PARSE_SERVER:1337/parse"
}
In the tutorial I'm watching, rather than "YOUR_APP_ID" and "http://YOUR_PARSE_SERVER:1337/parse" it just had a bunch of letters and numbers, which I would assume are the app ID and Parse server. My guess is, that I need an account to get those. Would that be correct? And, does anyone know why I can't seem to get an account? Thanks.
Parse.com is shutting down, so that's why you are not allowed to create new accounts on the service. Check the blog post.
They open sourced a nodeJS implementation, which you should definitely check out at link, and here is an example to get you started. You can easily use the deploy buttons to host the server on services like Heroku, AWS, Azure, etc. You can also deploy a server locally, for testing purposes.
Although it's true that Parse is discontinuing early next year, you can still setup a new app if you want to use the service for a shorter term project. Replace your code with the following.
Parse.setApplicationId("YOUR-APP-ID", clientKey: "YOUR-CLIENT-ID")
You can find your App ID and Client ID in your app's settings > security & keys.
EDIT: You definitely need an account for this to work.
How do I setup a Canvas payments callback url? I only need to set up for static pricing at this time within my app. Facebook requires a Payments Object under "Realtime Updates" heading. I have been searching everywhere for a simple straight example on how to do the complete process but have not been able to find one. I have been working through the Unity3d Friendsmash example project.
I haven't found much information on the callback, but since I don't really use it, I just used this code inside a PHP script to just make it work:
$hub_mode = $_GET['hub_mode'];
$hub_challenge = $_GET['hub_challenge'];
$hub_verify_token = $_GET['hub_verify_token'];
if ($hub_verify_token =='YourToken')
{
echo $hub_challenge;
}
I found the problem! I was using Parse which does not host php pages. I put my file on my bluehost account and it now works! My app can now show the pay dialog on Facebook using the callback url I gave it.
I'm using Rails to try and add an action for an object both defined for my app on the open graph. I am using an :after_filter in my controller to call the following after session#create:
#graph.put_connections('me', 'workkout:complete', :session => url_for([#plan, #session]))
I am getting the following back from Facebook:
{"error":{"type":"Exception","message":"Could not retrieve data from URL.","code":1660002}}
I have checked that the correct URL is passed to put_connections, and when I visit this URL using Facebook's Lint tool, everything is correct.
I can't understand why this isn't working, my only thought is that Facebook is hitting the URL moments before rails has generated the object? - not sure if that's even possible though.
Can anyone shed any light on this?
Turns out it was because the create action and the put_connection methods take place in independent threads and as such the URL is not ready when put_connections is called. Solution here http://railscasts.com/episodes/363-facebook-open-graph?autoplay=true
I have a toy facebook app I'm playing with so I can understand how it all works. It's fine if you go the the app like this: http://apps.facebook.com/pushup-challenge/ (and connect it). But if you then go to it from your facebook page, FB uses the URL http://apps.facebook.com/pushup-challenge/?ref=bookmarks.
In my log file, I see that FB is POSTing the data and including the /?ref=bookmarks to it's call to my codeigniter system. This is causing it to either say "invalid URI parameters" or give me a 404, depending on if I've edited the system/core/URI.php file to add rawurlencode() to a particular call.
I've tried using mod_rewrite to get rid of the query_string, too, but since it's POSTing, it doesn't appear to be working (though I'm not exactly sure why).
Has anyone else run into this? How did you fix it?
Thanks in advance,
Hans
try $config['uri_protocol'] = “PATH_INFO”; and set enable_query_strings = TRUE
or
set
$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-?=';
in config.php
Because it isn't calling your file by name (just ?ref=bookmarks) the server runs thru the standard default files: index.htm, index.html, index.asp. Because you need to accept a POST, you need a server that allows POSTs to htm & html if you choose to use those. Index.asp will accept POSTs on most servers, and that works for me.
SOLUTION: Add a file (index.asp), that calls the real app that you named in the App settings.
