I started a micro blogging app with Sinatra for class but for some reason I can not get the posts for my blog to show on the page. If any one can help it would be greatly appreciated. I don't know if I'm missing code or if I wrote piece of code incorrectly. Thanks again
get "/post/new" do
erb :new_post
end
post "/post/new" do
p '++++++++++++++++++++'
#post = Post.new(text: params[:text],
user_id: session[:user_id])
if #post.save
flash[:notice] = "Post has been added"
else
flash[:notice] = "Your post was not created, please review and resubmit."
end
redirect "/"
end
get "/posts" do
current_user
#posts = Post.all
erb :posts

I was thrown into a pretty old project, which is made in classic ASP. For our needs, I need to make a simple curl-request, to update some data.
I'm pretty new to ASP, so I looked for similar problems. I stumbled upon this
question here:
How can I post data using cURL in asp classic?
I tried to adapt as much as possible, but it seems like I'm missing an important thing and here I need your help:
functions.asp
public function makeCurlRequest(strMethod)
Dim http: Set http = Server.CreateObject("WinHttp.WinHttpRequest.5.1")
Dim privateKey
privateKey = "abc def"
Dim url: url = "https://sandbox.uberall.com/api/locations/322427?private_key=" & privateKey
Dim data: data = "{""location"":{""openingHours"":[{""dayOfWeek"":1,""from1"":""07:01"",""to1"":""07:02""}]}}"
'method needs to be PATCH
With http
Call .Open(strMethod, url, False)
Call .SetRequestHeader("Content-Type", "application/json")
Call .Send(data)
End With
If Left(http.Status, 1) = 2 Then
response.write("updated")
response.end()
Else
'Output error
Call Response.Write("Server returned: " & http.Status & " " & http.StatusText)
End If
end function
In my file, I simply call makeCurlRequest("PATCH").
Now it does indeed print "updated", so I guess I'm retrieving a 200, but the fields aren't updated.
Regarding to the uberall API, they require a location-object, which should be this, what is currently in my data-variable. (Checked it via a JSON-validator).
For a better readability, I'll provide the indented code as well, maybe here is an error:
{
"location":{
"openingHours":[
{
"dayOfWeek":1,
"from1":"07:01",
"to1":"07:02"
}
]
}
}
The ID's are correct, I double-checked that already. Maybe the payload is wrong? What might be the problem? Maybe data needs to be provided otherwise instead of this approach?
Looking at the examples on Uberall Tutorials Page
It looks as though the encapsulation of the location object is not necessary, instead structure the body like
{
"openingHours":[
{
"dayOfWeek":1,
"from1":"07:01",
"to1":"07:02"
}
]
}
In the code, change the data variable to be;
Dim data: data = "{""openingHours"":[{""dayOfWeek"":1,""from1"":""07:01"",""to1"":""07:02""}]}"
Must admit I had to dig around in the documentation to find an example that showed how they expected the body of the request to be structured, which isn't great for an API. Also if the payload was wrong you should be getting back an error so you know there was a problem with the payload, something along the lines of HTTP 400 Bad Request would make sense.
It's also possibly that the API uses HTTP 200 OK for everything, in which case any errors might get missed, so while testing you could just do something like this;
Dim http: Set http = Server.CreateObject("WinHttp.WinHttpRequest.5.1")
Dim privateKey
privateKey = "abc def"
Dim url: url = "https://sandbox.uberall.com/api/locations/322427?private_key=" & privateKey
'Purposefully passing the wrong structure to see what is returned.
Dim data: data = "{""location"":{""openingHours"":[{""dayOfWeek"":1,""from1"":""07:01"",""to1"":""07:02""}]}}"
'method needs to be PATCH
With http
Call .Open(strMethod, url, False)
Call .SetRequestHeader("Content-Type", "application/json")
Call .Send(data)
End With
'Not bothered about the status for now, just give me the response.
Call Response.Write("Server returned: " & http.Status & " " & http.StatusText)
Call Response.Write("Body: " & http.ResponseText)

Using the latest Facebook PHP SDK 4.4.0, in my main app page I can do the following to get a user id etc.
<?php
FacebookSession::setDefaultApplication(APP_ID, SECRET);
$helper = new FacebookRedirectLoginHelper( PAGE_URL );
$pageHelper = new FacebookPageTabHelper();
$session = $pageHelper->getSession();
echo '<p>You are currently viewing page: '. $pageHelper->getPageId() . '</p>';
// get user_id
echo '<p>User Id: ' . $pageHelper->getUserId() . '</p>';
// **depcrecated** get like status - use for likegates
echo '<p>You have '. ( $pageHelper->isLiked() ? 'LIKED' : 'NOT liked' ) . ' this page</p>';
// get admin status
echo '<p>You are '. ( $pageHelper->isAdmin() ? 'an ADMIN' : 'NOT an ADMIN' ) . '</p>';
?>
This does not work on sub pages of my app ... Why is the session (and amongst other things, the signed request) lost? How can I get them back and how can I get methods such as getUserId() from the the FacebookPageTabHelper to continue to work on sub pages?
full original question
I'm fairly new to Facebook app development and I'm having problems with session management and I just can't seem to be able to wrap my head around it. Of course it doesn't help that the official documentation is almost useless.
My problem is that the page session get lost when moving away from the apps main page to a subpage within the Facebook page tab app iframe.
I use the following PHP code to obtain the session and user id on the main (initial) app page and it works great:
<?php
FacebookSession::setDefaultApplication(APP_ID, SECRET);
$helper = new FacebookRedirectLoginHelper( PAGE_URL );
$pageHelper = new FacebookPageTabHelper();
$session = $pageHelper->getSession();
?>
But it doesn't work on sub pages :( when a user clicks on a menu item (or any other link inside the app/iframe), the session goes bye bye. Which is not ideal as I need the user id of the user to track whether or not that user has completed certain actions. Of course I could send the ID along with every request, but there must be a way to have a persisting session, no?
Is there a way to retrieve the session on a sub page in PHP? If so, how? Or do I have to load additional content using javascript? And how would that work, if I can't keep the session between requests and therefore have no way of identifying which user a request came from? How do others handle this?
What I'd like to avoid is to write my own user session management, which would solve the problem but is simply not in the budget and I was hoping I could work with what Facebook already had on offer. Especially since my app doesn't require user information/permissions of any kind.
Thanks a lot in advance for any info on this topic, greatly appreciated, going in circles here.
Edit to clarify: I thought of just saving the Facebook session in a PHP session cookie, but how would I use that to reconnect with Facebook after changing the page?
I finally managed to solve this problem. I'm not sure whether this is considered the right way or can even be a recommended way of doing this, but it works and since time is of the essence, I don't have much of a choice.
If anybody has any further ideas or suggestions, please comment.
Here's how I did it:
// store the signed request
if(isset($_REQUEST['signed_request'])) {
$_SESSION['signed_request'] = $_REQUEST['signed_request'];
} elseif($_SESSION['signed_request']) {
$_REQUEST['signed_request'] = $_GET['signed_request'] = $_POST['signed_request'] = $_SESSION['signed_request'];
}
// assign the stored signed request to REQUEST, GET and POST vars (the unsavory bit, imo)
$_REQUEST['signed_request'] = $_GET['signed_request'] = $_POST['signed_request'] = $_SESSION['signedRequest'];
FacebookSession::setDefaultApplication(APP_ID, APP_SECRET);
$accessToken = APP_ID . '|' . APP_SECRET;
$this->session = new FacebookSession($accessToken);
$pageHelper = new FacebookPageTabHelper();
$isAdmin = ($this->pageHelper->getPageData('admin')) ? $this->pageHelper->getPageData('admin') : 0;
// get pade id
echo '<p>You are currently viewing page: '. $pageHelper->getPageId() . '</p>';
// get user_id
echo '<p>User Id: ' . $pageHelper->getUserId() . '</p>';
// get admin status
echo '<p>You are '. ( $isAdmin ? 'an ADMIN' : 'NOT an ADMIN' ) . '</p>';
I'm using django-facebook's Open Facebook API to try to defer a post with an image to a facebook page. The (relevant part of the) code is:
graph_api = OpenFacebook(integration.long_lived_page_token)
message = "something"
picture = "http://example.com/image.jpg"
d = datetime.datetime.strptime('07-25-2014 06:40 pm UTC', '%m-%d-%Y %I:%M %p %Z')
timestamp = timestamp = int(time.mktime(d.timetuple()))
try:
facebook_response = graph_api.set('/{0}/feed'.format(
facebook_page_id), message=message,
link=picture, picture=picture,
scheduled_publish_time=timestamp, published=0)
except:
...
This seems to work fine (I get the post id on facebook_response) but when the time comes to post this scheduled post nothing happens. When I check at the facebook page I see an error saying 'Sorry, something went wrong publishing this scheduled post' and offers to delete it or post it then. So, I can't seem to figure out what am I doing wrong.
I found a similar question but it does not offer a good answer.
Oh, I forgot to say when I remove timestamp and published=0 parameters (i.e. I post on that exact moment), the post gets created and published on the page's feed.
I am trying to create new test page from REST api calls in Fitnesse. The page is being created but the contents is not being added.
I am using addChild responder.
here is my code.
DefaultHttpClient client = new DefaultHttpClient();
HttpGet post = new HttpGet("http://localhost:80/TestSuite?responder=addChild&pageName=RestSuite&pageType=Suite&content=valuetosave");
HttpResponse response = client.execute(post);
String str1 = EntityUtils.toString(response.getEntity());
System.out.println(str1);
I searched a lot but couldn't find any examples also.. please help.
Thanks in advance.
After lots of efforts I found that that documentation is wrong for Rest on fitness.org the parameter in the request is not 'content' but 'pageContent'...
I have an app and I am able to post to a user's wall when they allow it. However, when the app makes a wall post, it shows that it is from me (the administrator of the app) posting on the user's wall. I want it to look like it was the actual user posting on their own wall... (using VS 2008, .Net 3.5)
Here is my code...
Dim oFB As Facebook.FacebookClient
Dim sAppId As String = "my app id"
Dim sAppSecret As String = "it's a secret"
Dim webClient As System.Net.WebClient = New System.Net.WebClient()
Dim result As String = webClient.DownloadString("https://graph.facebook.com/oauth/access_token?client_id=" & sAppId & "&client_secret=" & sAppSecret & "&grant_type=client_credentials")
'- Access token changes every hour
oFB = New Facebook.FacebookClient(sAppId, sAppSecret)
oFB.AccessToken = result.Substring(result.IndexOf("=") + 1)
Dim oPost As Collections.Generic.IDictionary(Of String, Object)
oPost = New Collections.Generic.Dictionary(Of String, Object)
oPost.Add("message", "(websitepipeline test post) Check out this new product!") '- This is the wall post / the description input for the DM function
oPost.Add("link", "http://www.example.com/content/somepage.html")
oPost.Add("from", "the user who authenticated")
oFB.Post("the user who authenticated/feed", oPost)
Here's a link to a library someone made for .NET that it wraps around ;) [link]http://www.lagorio.net/windows/facebook/) Obviously you will need to present a FBDialog asking the user for his credentials of course! :) Not too sure what library your using but maybe the string for "from" is incorrect or needs to be a user token of some sort
Use the .setStatus command w/ this API.
