使用Javascript API检索访问令牌
|
这是该主题的后续内容：将signed_request和AJAX调用传递给装饰有CanvasAuthorize的ActionMethod
由于我无法使signed_request不能为null，因此我认为我要在客户端对用户进行身份验证，然后将访问令牌与AJAX调用一起发送到服务器端（ASP.NET MVC） 。不幸的是，我也无法使它正常工作！这是我的Javascript代码（从文档中获得）：
function postOnFacebook(msg, itemLink, pic, itemTitle, signedReq) {
var siteUrl = \'http://www.localhost:2732\';
var appID = 193005690721590;
if (window.location.hash.length == 0) {
var path = \'https://www.facebook.com/dialog/oauth?\';
var queryParams = [\'client_id=\' + appID,
\'redirect_uri=\' + window.location,
\'response_type=token\',
\'scope=offline_access\'];
var query = queryParams.join(\'&\');
var url = path + query;
window.open(url);
} else {
var accessToken = window.location.hash.substring(1);
var path = \"https://graph.facebook.com/me?\";
var queryParams = [accessToken];
var query = queryParams.join(\'&\');
var url = path + query;
// use jsonp to call the graph
var script = document.createElement(\'script\');
script.src = url;
document.body.appendChild(script);
}
$.ajax({
url: \'/Facebook/Share\',
data: {
\'message\': msg,
\'link\': siteUrl + itemLink,
\'picture\': siteUrl + pic,
\'name\' : itemTitle,
\'accessToken\': accessToken
},
type: \'get\',
success: function(data) {
if(data.result == \"success\") {
alert(\"item was posted on facebook\");
}
}
});
}
public ActionResult Share(string message, string link, string picture, string name, string accessToken)
{
if (FacebookWebContext.Current.Session == null)
return RedirectToAction(\"Login\");
var fb = new FacebookWebClient(accessToken);
var postArgs = new Dictionary<string, string>();
postArgs[\"message\"] = message;
postArgs[\"link\"] = link;
postArgs[\"picture\"] = picture;
postArgs[\"name\"] = name;
fb.Post(\"/me/feed\", postArgs);
return Json(new {result = \"success\"}, JsonRequestBehavior.AllowGet);
}
}

<input id=\"AccessToken\" type=\"text\" value=\"\" /> <div id=\"fb-root\"></div> <script src=\"https://connect.facebook.net/en_US/all.js\" type=\"text/javascript\"></script> <script src=\"https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js\" type=\"text/javascript\"></script> <script type=\"text/javascript\"> $(document).ready(function () { FB.init({ appId: \'insert your appID value here\', cookie: true, xfbml: true, status: true }); FB.getLoginStatus(function (response) { if (response.authResponse) { $(\'#AccessToken\').val(response.authResponse.accessToken); } else { // do something...maybe show a login prompt } }); }); </script>
