Is there documentation for the makeRequest function? Also, can it call webservices?

Hey, there's not really any official documentation yet, but see the comments in MyOpenSpace.js and opensocialreference.js for more info.  And yes, you can call web services.

Comments below:

/**
 * Fetches content from the provided URL and feeds that content into the
 * callback function.
 * @param {String} url The URL where the content is located
 * @param {Function} callback The function to call with the data from the URL
 *     once it is fetched
 * @param {Map.<opensocial.ContentRequestParameters, Object>} opt_params
 *     Additional parameters to pass to the request
 *
 * @private
 */

 /**
 * makeRequest implementation using proxy
 * Fetches content from the provided URL and feeds that content into the callback function
 * @param {String} url The URL where content is located
 * @param {Function} callback The function to call with the data returned from url
 * @param {opensocial.ContentRequestParameters} Additional parameters to pass to the request
 */

<div id="target" style="padding:10px;">
waiting....
</div>

<script type="text/javascript">


function init() {
    
	var target = document.getElementById('target');
	try{
	    opensocial.Container.get().makeRequest(
			"http://www.fuali.com/crap.html", 
			function(content, errored) 
			{
				if (!errored) {target.innerHTML = content.responseText;}
				else {target.innerHTML = 'error';}
			}, opensocial.ContentRequestParameters.MethodType.GET);
		
	}
	catch(er){
		target.style.backgroundColor = '#f00';
		target.style.color = '#fff';

		target.innerHTML = er.message;	
	}
}
init();

</script>

 One quick note regarding callbacks...

After this most recent push, the signature is now makeRequest_callback(content, url, error)

content will be based on your CONTENT_TYPE, so could be an XMLDocument, string, or MyOpenSpace.Feed.RSS2 (so far I've only written RSS2.0 support).

The idea behind passing back url is you can reuse callbacks based on url.  If more finite control is needed, ask for it here =)

Any eta on a fix for makeRequest?  I'm getting runtime errors from relay.proxy for most sites 

I have been trying to do write an RSS feed reader, but I am getting an errorCode of "unauthorized". 

<div id="divHello"></div>
<script type="text/javascript">
      function processFeed(feed) {
var html= "";
html += "Feed object properties: "
		for (property in feed) {
html += "<br>" + property;
 }
	  if (feed.errorCode) {
	html += "<br>errorCode: "+feed.errorCode;
	html += "<br>errorMessage: "+feed.errorMessage;
} else {
          // Access the fields in the feed
          html += "<b>" + feed.Title + "</b>";
          html += "" + feed.Description + "<br>";
	  alert(feed.Title);
          alert(feed.Description);
}
          document.getElementById('divHello').innerHTML = html;

      }
      opensocial.makeRequest("http://www.myblog.com/rss", processFeed, {'method':'GET','contentType':'feed','numEntries':'5','getSummaries':'true'});
</script>

 Is this the right way to do this?  I am assuming that this is the bug everyone is referring to.

I am running into multiple error messages from the "relay.proxy" that makeRequest is using. 

http://api.msappspace.com/relay.proxy?opensocial_token=MIGvBgorBgEEAYI3WAOCoIGgMIGdBgorBgEEAYI3WAMBoIGOMIGLAgMCAAECAmYDAgIAwAQIX7VU6HEggv4EEA%2Fjf5ui4R3jtZ6pHaKETk0EYBEnnWKIek2lQ7ZDsxhxDHA6GdYdpTBXn8EMH%2BVRsSAqlWS8BQX731Cn%2FEWtpeoL35D5PCWMM6jVdI0IfcY5lj4gK11oUxdxwKMwBd28SLtNDy5ibwuvu8Dd3Q1Wqh%2F4kg%3D%3D&opensocial_url=http://www.myspace.com/ktrout 

is returning

<error xmlns="api-v1.myspace.com"><statuscode>401</statuscode><message>Not an OpenSocial resource.</message></error>

or sometimes "Runtime Error" 

Hi all, we're working on getting makeRequest up and running right now, it'll hopefully be fixed shortly.

Thanks,

Chad 

 WRT Feed capabilities via makeRequest(), we currently support RSS2 and are working on ATOM feeds.  That said, we are currently doing the paging/summarization on the client and that just won't do.  In the meantime, just expect the XHR to take a little while longer than the expected content in your callback should take.

Cheers,

Max 

 makeRequest has been pushed to production (not the ATOM bits), so please try your FEED content request again.

Cheers,

 OK... it was fixed than busted. fixed... then busted....

Long story short: "We gotz it working better than ever!"

Big thanks to Paul Walker, Haider and Max Newbould to get this thing at it's best.

I posted this in the bugs topic as well. I have found that some feeds don't work.  This could be because they have 

ATOM tags in them as well as RSS 2.0.  I also noticed that the NUM_ENTRIES parameter for makeRequest on a feed doesn't 

seem to have any effect.  It always gives me the default number of 3 posts.

Here is my code:

<div id="rssFeedContainer"></div>
<script type="text/javascript">
function processFeed(feed, url, error) {
	var html = "";
	if (!error) {
	    for (var i=0; i < feed.items.length; i++) {
			var title = feed.items[i].title;
			var desc = feed.items[i].description;
			html += "<div><b>" + feed.items[i].title + "</b></div>";
	        html += "<div>" + feed.items[i].description + "</div><br>";
        }
	} else {	
		html += "<br>Error when fetching url: " + url;
	}
	document.getElementById('rssFeedContainer').innerHTML = html;
}

function init() {
	var rssContainer = document.getElementById('rssFeedContainer');
	try {
		params = {};
		params[opensocial.ContentRequestParameters.METHOD] = opensocial.ContentRequestParameters.MethodType.GET;
		params[opensocial.ContentRequestParameters.CONTENT_TYPE] = opensocial.ContentRequestParameters.ContentType.FEED;
		params[opensocial.ContentRequestParameters.NUM_ENTRIES] = '5';
		opensocial.Container.get().makeRequest("http://exported.tumblr.com/rss", processFeed, params);	
	} catch (e) {
		rssContainer.innerHTML = e.message;
	}
}
init();
</script>      

Example feeds that do work:

Tumblr feeds

Example feeds that don't work: 

MySpace Developer Forum Feeds

Wordpress feeds

Feedburner feeds

I was just trying this sample code verbatim from the opensocial api docs:

    <div id="content_div"></div>
    <script type="text/javascript">
      opensocial.makeRequest("http://www.google.com",
        function(response) {              
        var html = response.substr(0,400); 
        document.getElementById('content_div').innerHTML = html;
      }, {'method' : 'GET', 'contentType' : 'html'});
    </script>

Any reason why this does not work?
