Can't figure out how to make calls against the Facebook ApiClient in the js library
Starting from this very nice article about doing facebook integration using the javascript API, I was able to successfully make several calls against the FB.Connect namespace.
I am now interested in calls that are in the FB.ApiClient library, and have tried a few simple ones. I cannot get this to work, is there something I have to do that different? Specifically, I would like to make calls against开发者_Go百科 the events_get methods.
Documentation:
- Facebook JavaScript API
- streamPublish (working well!)
- events_get (method I would really like to get working)
Code:
Working JavaScript:
function updateStatus() {
FB.Connect.streamPublish();
}
Error: FB.ApiClient.get_apiKey is not a function
function getEventInfo() {
FB.ApiClient.get_apiKey();
}
the namespace and methods are inconsistent in the way that they are named and used. To access the apiClient, you must use FB.Facebook.apiClient.
In short. Instead of calling:
FB.apiClient.get_apiKey();
call:
FB.Facebook.apiClient.get_apiKey();
Below, I have included a complete example, where I worked out several methods on the Connect and ApiClient APIs. This is working as of 1/22/09.

Is FB.ApiClient defined? Have you tried wrapping it in a FB_RequireFeatures call, and making sure it's initialised? E.g.
FB_RequireFeatures(["Api"], function(){
FB.Facebook.init('b9d3cab9951682757d0488290545d854', 'xd_receiver.htm');
FB.Facebook.get_sessionState().waitUntilReady(function(){
FB.Facebook.apiClient.friends_get(null, function(result, ex) {
alert(result)
});
});
加载中,请稍侯......
