appParams - pagination

* Echannel Networks* — Sun, 09 Mar 2008 00:05:23 GMT

I've been reading here that you can pass appParams to the script: http://code.google.com/apis/orkut/docs/orkutdevguide.html#ops_paging

I tried that with Canvas.aspx?appId=XXX&appParams=blah however I'm not getting anything.

Does anybody have any working examples?

Script error on IE after Activities or notifications

Daniel Calife — Wed, 18 Nov 2009 14:01:07 GMT

Hello, after the user send an activity or app invitation there is a script error that blocks all other server requests. This happens just on IE.

Have you had the same problem? How to fix it?

the code i use for activity is here;

self.createTemplateActivity = function(id, variables, media, callback) {
		if (self.activeRequest)
			return false;
		
		self.activeRequest = true;
		var params = {};
		params[opensocial.Activity.Field.TITLE_ID] = id;
		params[opensocial.Activity.Field.TEMPLATE_PARAMS] = variables;
		params[opensocial.Activity.Field.MEDIA_ITEMS] = mountMedia(media);
		
		var activity = opensocial.newActivity(params);
		opensocial.requestCreateActivity(activity, opensocial.CreateActivityPriority.HIGH, dataLoaded);

		function dataLoaded(response) {
			//debug(response);
			//for (var i in response) debug(i + " : " + response);
			var result = "0";
			if (!response.hadError()) {
				result = "1";
			}
			self.activeRequest = false;
			callback(result);
		}
	};

Thank you,

Status And Mood Set/Update

Groundrush — Thu, 22 Oct 2009 19:08:24 GMT

I have the javascript code to retrieve the mood and status in v0.8. Does anyone have and example or could point me in the right direction to update the mood and status using javascript.

opensocial_viewer_id == -1 ??? what does this mean?

Cyn — Sun, 20 Apr 2008 22:04:35 GMT

I'm getting a small stream of views to the canvas where the GET variables are properly populated from makerequest, but every once in a while I get one where the opensocial_viewer_id is -1.

What is this? I can't replicate this, so I don't know how to handle it.

Just guessing: I know there's a condition where, after some time, you'll get auto-logged out, but it still looks like you're logged in. Most profile stuff doesn't care, but apps do. Is that what's going on?

request permissions

Mahesh — Mon, 02 Nov 2009 17:30:05 GMT

Hello guys, I have an application in which I'm loading content from my website in an IFrame. From the IFrame, I'm trying to prompt the user to add the application like on this page - http://profile.myspace.com/Modules/Applications/Pages/Canvas.aspx?appId=124833. I've followed all the recommended steps, like adding the script tags to my code, and registering the required variables (panelId). However, no matter what I do, I can't seem to get it to work. Here's the code snippet inside my IFrame: var perms = MyOpenSpace.Permission['VIEWER_DISPLAY_ON_PROFILE']; var hasPerm = container.hasPermission(perms); alert('has permissions: ' + hasPerm); var reason = "Test permission request"; reqCallback = function (response) { alert("call back!"); }; if (!hasPerm) { alert('about to call request permission, container:' + container.requestPermission); container.requestPermission(perms, reason, reqCallback); } The first alert (inside the if block) appears. When I checked what was happening using Firebug, I noticed the error message "Unknown RPC service" right after the alert - on the line that says container.requestPermissions(.... Can anyone help please?

OAuth, getting it to work

► Ҝėvȋń ◄ ♂ — Tue, 11 Mar 2008 00:19:35 GMT

No doubt there's a lot of confusion in getting OAuth to work; it doesn't help that you're probably debugging against a boolean output. Thought I'd share my fustrations and "tips" on how I was able to get it working, in the hopes of saving someone from jumping off a bridget :) Some of this is from other posts, some is original.

Cheers,
Kevin

Helpful links:

OAuth Tool: http://developer.myspace.com/Modules/APIs/Pages/OAuthTool.aspx
OAuth Spec: http://developer.myspace.com/community/RestfulAPIs/authentication.aspx (not so helpful)
OAuth Standard: http://oauth.net/core/1.0/ (not necessary for those who just want it to work)

Definitions:

Consumer Key - Application URI, looks like http://www.myspace.com/123456789 - but you need to url encode it so that it's recieved like: http%3A%2F%2Fwww.myspace.com%123456789
Consumer Secret - Security Key, looks like 079b72r9z9884e17b6504f723a179c23
OAuth Token - Is a request paramater, is indexed by "oauth_token" (ie, Request.params["oauth_token"]
OAuth Token Secret - this is an empty string, ""

Consume key & consumer secret are both found in the My Apps / App Details page. Never share the consumer secret key with anyone ;)

Pseudocode:
(found in many formums)

string generatedStr = @"your generated string here"; (samples below)
string key = UrlEncode(string.Format("{0}&{1}", UrlEncode(consumerSecret), UrlEncode(tokenSecret)));
HashAlgorithm hashAlgorithm = new HMACSHA1(Encoding.UTF8.GetBytes(key));
string computedHash = Convert.ToBase64String(hashAlgorithm.ComputeHash(Encoding.UTF8.GetBytes(str))));
return computedHash.compareTo(sentHash) == 0;

Cryptography Basics

The goal is to compute a hash that matches the hash provided by the MySpace server...

Keep in mind that purpose of this execise (of signing the request) - to keep the middle man out. The spec allows no room for errors (even if it's not published correctly), and all generated strings are case senstivie. In the .Net platform, that means the default UrlEncode function actually generates the wrong case!! So, yes, your generated string & keys have to be exact...

Debugging:

Remove as much abstraction as possible, including environment, etc. Start with the OAuth tool, which will allow you to work against a constant set of paramaters.

use realistic values (yet keep them simple)
Set the version to 1.0 (server does anyways)
Take the string generated output (see sample base string & sample signature) and get it to work in your algorithm first!

Sample Base String:
GET&http%3A%2F%2Fapi.myspace.com%2Fmystuff%2Fdynamic.aspx&oauth_consumer_key%3Dhttp%253A%252F%252Fwww.myspace.com%252F330069419%26oauth_nonce%3D987654321%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1205192397%26oauth_token%3DoauthToken%26oauth_version%3D1.0

Signature:
azN0BCWSkoCyfDAMrl5JLpgSSac=

Pain points so far - generating the
EXACT
base string as the OAuth tool!
The generated base string includes whitespace (none), and casing (may not be correct if using system libraries). This is by far the hardest part, so don't bother moving forward without being able to replicating the generated string.
I'd suggest using a tool like Beyond Compare (or other visual diff tool), where you split each line up by the = sign (encoded %26), so you can truly compare paramater by paramater. It has to be exact!
I also had to double encode the consumer key to match the OAuth Tool's base string.
Do not drop empty variables (ie, if a paramater is empty / null, you still need to include it)
The normalized request paramaters are as follows:

start with all org paramaters provide
remove all OAuth paramaters except those needed by myspace (needed: OAuthVersionKey, OAuthNonceKey, OAuthTimestampKey, OAuthSignatureMethodKey, OAuthConsumerKeyKey, OAuthTokenKey)
sort remaining paramaters alphabetically, numbers first, 0 before 1
Unconfirmed: "(" and ")" characters may need to be encoded, this is true for other cryto projects i've done in the past. I've seen forum posts stating as much.

Each portion of the string is url encoded; not the entire string:

httpMethod.ToUpper() + "&" + UrlEncode(url) + "&" + UrlEncode(normalizedRequestParamaters)

Once you have a matching base string, now try to generate a signature. The pseudocode to generate your own signature is above. Keep a look out for encoding (UTF8).
A sample key should match the following format: "079b72r9z9884e17b6504f723a179c23&" (note the trailing "&")
If you don't have the OAuth signature, then you've already gone wrong; no need to consider other environmental problems. Repeat debugging until you get this far.

double, tripple, check your base generated string to the one provided by the OAuth tool.

From here, it's time to move against the MySpace server. It shouldn't be too hard, other then each request will be different from the previous - that is, the timestamp will always be different, so you can no longer hard code anything; all variables must come from the request that originated at MySpace.
Also, consider that the OAuth tool, even with the same variables that the myspace server send, will generate a different signature. This is because there are extra paramaters, that can not be input into the OAuth tool (ie, viewer_id, owner_id, etc). So it's time to leave it behind :)
At this time, you're flying somewhat blind. But, as long as you can normalize your parameters properly, you should be OK... But:
Certain characters (?, &, (, ), %, etc) may cause problems - try them in the OAuth tool to see if you can get an exact match with your generated string & signature.

OK, that's it for now. Hopefully this thread will remain useful / grow with time. I can say, that OAuth is possible, but it's important to get the simple steps working first...

Good luck!

How do I fetch data by ID?

Darrell (SNAP Interactive) — Thu, 13 Mar 2008 01:18:49 GMT

For example, i see from the docs that there is a getById() function, but to which object does this function belong?

var thumbnailRequest = dataRequest.newFetchPeopleRequest(opensocial.Person.Field.THUMBNAIL_URL.getById(PersonID));

This doesn't work - the error is:

opensocial.Person.Field.THUMBNAIL_URL.getById is not a function

Can someone point me in the right direction?

Thanks...

opensocial-actionscript-client

Ellis — Fri, 09 Oct 2009 10:19:27 GMT

Hi, I'm embedding a Flash file in the HTML/JavaScript container, and would like to use an API to call opensocial instead of making all the ExternalInterface calls myself. MySpaceID for AS3 is REST only. Since I want to use JavaScript, i've found that the latest opensocial JavaScript API for ActionScript is "opensocial-actionscript-client". I've run into a few problems though. It seems that MySpace only support 0.8 of opensocial, but this library is for 0.9. Also, it doesn't have MySpace extensions. Lastly, I follow the sample to try to use the API, but it doesn't work:

client = new JsWrapperClient("opensocial.flash");
client.addEventListener(OpenSocialClientEvent.CLIENT_READY, onReady);
printer.print("starting client");
client.start();

the problem is that onReady never gets called. I looked into the opensocial-actionscript-client container code, and it's checking to see if "opensocial.flash.jsReady" is set to true, and only then will it continue. But MySpace's OpenSocial implementation doesn't provide opensocial.flash. Is this a difference between 0.8 and 0.9? Will MySpace be providing their own javascript wrapper for ActionScript?

Regards...

gadgets.window.adjustHeight - does this work from an IFRAME app?

Mike — Fri, 24 Jul 2009 22:12:26 GMT

I've seen several references to it in the posts in terms of resizing the canvas height.

I'm calling it from my application, and it currently does nothing.

I am including the following dependency scripts:

<script src="http://x.myspacecdn.com/OpenSocial/references/gadgets003.js" type="text/javascript"></script>

<script src="http://x.myspacecdn.com/modules/common/static/js/Apps/ifpc003.js" type="text/javascript"></script>
<script src="http://x.myspacecdn.com/modules/common/static/js/Apps/json001.js" type="text/javascript"></script>
<script src="http://x.myspacecdn.com/OpenSocial/IFPC_externalIframe004.js" type="text/javascript"></script>

And I am using the following initialization script:

//<![CDATA[
    // set the correct panel id. The name will be apppanel_XXXXXX_canvas where
    // XXXXXX is the id of the application
        MyOpenSpace.MySpaceContainer.get().registerParam("panelId", "apppanel_139844_canvas");
        //Set the location of the ifpc_relay_external001.html within your server
        MyOpenSpace.MySpaceContainer.get().registerParam("localRelay", "./ifpc_relay_external001.html");
   gadgets.util.registerOnLoadHandler(MySpace_ResizeFrame);
    //]]>

 with the contents of  MySpace_ResizeFrame as follows:

function MySpace_ResizeFrame() {
    gadgets.window.adjustHeight();
}

This seems to be doing exactly zip. Can one of the gurus please look at this and tell me what I am doing wrong?

How do you resize the height of the profile surface?

Ramzi — Fri, 07 Aug 2009 18:18:48 GMT

Hello

In our app, I am trying to resize the height of the profile surface in the profile surface code by calling gadgets.window.adjustHeight(height), but this seems to have no effect what so ever. Can anyone help me in how you dynamically adjust the height of a profile.

Friends getTotalSize() no longer works?

Revolutionary Productions — Tue, 25 Aug 2009 20:37:51 GMT

I've been out of the loop for a couple of months due to back surgery but my code for calculating the number of friends of the viewing user no longer works. Here is a clip of my code:

function invitePage(page)
{
   FRIEND_PAGE = page;
   FRIEND_INVITE.length = 0;
   var req = opensocial.newDataRequest();
   var params = {};
   params[opensocial.DataRequest.PeopleRequestFields.FILTER] = opensocial.DataRequest.FilterType.ALL;
   params[opensocial.DataRequest.PeopleRequestFields.FIRST] = ((page - 1) * 40);
   params[opensocial.DataRequest.PeopleRequestFields.MAX] = 20;
req.add(req.newFetchPeopleRequest(opensocial.DataRequest.Group.VIEWER_FRIENDS, params));
   req.send(fillFriendsForInvite);
   document.location.hash = "#inviteTop";
}
function fillFriendsForInvite(dataResponse)
{
   var friendsDataGroup = dataResponse.get(opensocial.DataRequest.Group.VIEWER_FRIENDS);
   var friendsData = friendsDataGroup.getData();
   var friendsSize = friendsData.getTotalSize();
   debug("total friends: " + friendsSize);

}

In this case, the debug outputs 40, the max number of friends returned for that page but the total number of friends in all is actually over 70. Was there a change that I'm not aware of? I cannot seem to find much about this on the forums.

Thanks ahead of time for any help!

MakeRequest 500 Request Timed Out

finwe — Sat, 15 Aug 2009 00:25:18 GMT

My application has started to return this error for a last few hours.

A "CONTENT.TEXT" type of request in the application can not response properly.

Everything was just fine until now. This problem has just suddenly started.

http://api.msappspace.com/proxy/relay.proxy?opensocial_url=http%3A//www.deviantsh*****************fresh=3600&ts=1250295366194

This proxy url returns timed out error. But the original external url in the parameter works fine without proxy.

But i don't think it is something about that original url.

http://www.deviantshare.com/GenDifiUrl.aspx?devName=finwe&myspace=eldar_finwe&devCount=15&devSort=0&devFolder=all&i=396

This an example external requested url in that makeRequest.

It responses in 60ms and the content is only one line text. It can't be about external site.

What is the problem? Is this something temporary?

Please support.

Thanks.
