Anyone could please give me an idea of how to call the FB payments dialog using the FB.ui method in c++?
I do have the c# function that I need to convert to c++:
FB.ui({
method: 'pay',
action: 'purchaseitem',
product: "",
request_id: "1234567890ABCDEF"
}, function (response) {
console.log('Payment completed', response);
print(response);
if (response.payment_id) {
facebookPurchaseId = response.payment_id;
payForOrder();
}
});
Tried using a converter app but it wasn't recognizing these methods.

How is it possible to access the loopback context (or simple Express req object) from within the model's logic?
It is critical to be able to know more about the request itself (current user identity more than anything else) inside the model's logic. When I override a built-in method (via custom script or from the model.js file) or develop a custom remote method, I would like to access the Express req object.
As loopback.getCurrentContext() is declared to be buggy, I cannot use it.
Ideas?
PS:
I find this page confusing: http://loopback.io/doc/en/lb2/Using-current-context.html
First it's said (and marked in red as important!) it is not recommended to use LoopBackContext.getCurrentContext() and then it's used it in each example!?
What's the point to give examples that do not work? Should we simply ignore the complete page? If so, what about the context? :)
Any clarification on this topic is much appreciated.
You can get access to express req object by using remote hooks
var loopback = require('loopback');
module.exports = function (MyModel) {
MyModel.beforeRemote('findOne', function (ctx, model, next) {
//access to ctx.req
console.log(ctx.req.headers)
next()
})
MyModel.beforeRemote('my-custom-remote-method', function (ctx, model, next) {
console.log(ctx.req.headers)
next()
})
}
Sure, you can use a beforeRemote hook to modify the ctx.args property. This property is the input of the remote method (that is, custom or built-in). This way, you can copy a part of the request inside this property, and it will be passed to the build-in method
Example 1 with the built-in method findOne.
MyModel.beforeRemote('findOne', function (ctx, model, next) {
ctx.args.filter.extrafield = ctx.req.headers['some-header'];
next();
});
Then override the findOne method since it's what you want to do
MyModel.on('dataSourceAttached', function(obj){
var findOne = MyModel.findOne;
MyModel.findOne = function(filter, cb) {
console.log(filter.extrafield); // Print what was in the header
return findOne.apply(this, arguments);
};
});
And finally call the method with curl
curl -H "some-header: 'hello, world!'" localhost:3000/api/MyModel/findOne
Example 2 with a custom remote printToken, to help you understand further
MyModel.beforeRemote('printToken', function (ctx, model, next) {
ctx.args.token = ctx.req.headers['some-header'];
next();
});
MyModel.printToken = function(token, cb) {
console.log(token);
cb();
}
MyModel.remoteMethod(
'printToken',
{
accepts: {arg: 'token', type: 'string', optional: true}
}
);
Then call the remote with curl, and pass the expected header
curl -H "some-header: 'hello, world!'" localhost:3000/api/MyModel/printToken
EDIT: There is a simpler solution that only works for custom remote
When defining your remote method, it is possible to tell loopback to pass elements of the http request to your remote directly as an input argument
MyModel.remoteMethod(
'printToken',
{
accepts: [
{arg: 'req', type: 'object', 'http': {source: 'req'}},
{arg: 'res', type: 'object', 'http': {source: 'res'}}
]
}
);
This way, your remote can access the req and res objects. This is documented here

I finally resorted to native Activex calls as no other way seem to work for me. Personally I wanted to avoid using it. But It works well.
A word of caution here, activeX are not very well supported in browsers other than IE so you need to either have IE Only application or convince the client to upgrade to higher version of asp.net.
I need to pass the response from ajax call to a jquery template.The response json is not malformed.I have checked this by using alert statements in the ajax fn.When the response is passed to the template,it does not get recognized.For example,when I use ${field1} in template,nothing gets displayed in the browser.No error messages are displayed at the browser.Can someone help me fix this issue?
Json response from server:
{
"field1": 23432434,
"field2": "sometext",
}
Ajax fn:
function getinfo(uri)
{
jQuery.ajax({
url: 'http://{{request.META.SERVER_NAME}}'+uri,
success: function(info) {
return info;
},
async: false,
dataType: 'jsonp'
});
}
Template:
<script id="infoTemplate" type="text/x-jQuery-tmpl">
<div>${field1}</div>
</script>
Code to Bind JSON to template:
<script id="Template1" type="text/x-jQuery-tmpl">
{{tmpl(getinfo(uri)) "#infoTemplate"}}
</script>
Note: I can't use the following method to bind JSON with template.That's a long story.
function getinfo(uri)
{
$.getJSON('http://{{request.META.SERVER_NAME}}'+uri, function(data) {
$("#infoTemplate").tmpl(data).appendTo("#somedivid");
});
}
That's not how callbacks work. You're returning info to the callback function, and not to getinfo.
You either have to do something like you proposed after, or keep the result from the ajax call in a global var and call the tmpl function after while, to be sure that you have already got the answer from the ajax call. The first way is the way to go.
I am working on a Facebook canvas iFrame application, and I`m going insane.
I am trying to check if a user is a fan of the page where the app is located, so that I can allow or disallow voting.
I use the following code:
function CheckFan() {
FB.init({
appId: 'xxxxxxxxxxxxxxxxxxxxxxxxxx',
status: true, // check login status
cookie: true, // enable cookies to allow the server to access the session
xfbml: true // parse XFBML
});
FB.api({ method: 'pages.isFan', page_id: '145116742177104' }
, function(resp) {
if (resp) { $('#main_frame').show(); $('#non_fan').hide(); }
else { $('#main_frame').hide(); $('#non_fan').show(); }
});
}
This JS SDK is driving me up the wall, while calling the documentation "incomplete" is an insult to incompleteness.
Any input will be appriciated.
Thank you!

This has been deprecated by Facebook.
A new Graph API alternative will hopfuly be available by the time we need to deploy the app.
For now I use FQL:
FB.api({ method: 'fql.query', query: 'SELECT uid FROM page_fan WHERE uid= ' + user_id + ' AND page_id=145116742177104' },
function(result) {
if (result.length)
{ $('.main_frame').show(); $('#non_fan').hide(); } else { $('.main_frame').hide(); $('#non_fan').show(); }
});
I started playing a bit with Sencha Touch.
So I've built a really simple application based on one of the examples just to see how it goes.
Basically it creates a JSON Request which executes a Last.FM web service to get music events near the user's location.
Here's the JSON code:
var makeJSONPRequest = function() {
Ext.util.JSONP.request({
url: 'http://ws.audioscrobbler.com/2.0/',
params: {
method: 'geo.getEvents',
location: 'São+Paulo+-+SP',
format: 'json',
callback: 'callback',
api_key: 'b25b959554ed76058ac220b7b2e0a026'
},
callback: function(result) {
var events = result.data.events;
if (events) {
var html = tpl.applyTemplate(events);
Ext.getCmp('content').update(html);
}
else {
alert('There was an error retrieving the events.');
}
Ext.getCmp('status').setTitle('Events in Sao Paulo, SP');
}
})
};
But every time I try to run it, I get the following exception:
Uncaught SyntaxError: Unexpected token :
Anyone has a clue?
A couple of things. First of all the "Uncaught SyntaxError: Unexpected token :" means the browser javascript engine is complaining about a colon ":" that has been put in the wrong place.
The problem will most likely be in the returned JSON. Since whatever the server returns will be run though the eval("{JSON HTTP RESULT}") function in javascript, the most likely thing is that your problem is in there somewhere.
I've put your code on a little sencha test harness and found a couple of problems with it.
First: My browser was not too happy with the "squiggly ã" in location: 'São+Paulo+-+SP', so I had to change this to location: 'Sao+Paulo,+Brazil', which worked and returned the correct results from the audioscribbler API.
Second: I notice you added a callback: 'callback', line to your request parameters, which changes the nature of the HTTP result and returns the JSON as follows:
callback({ // a function call "callback(" gets added here
"events":{
"event":[
{
"id":"1713341",
"title":"Skank",
"artists":{
"artist":"Skank",
"headliner":"Skank"
},
// blah blah more stuff
"#attr":{
"location":"Sao Paulo, Brazil",
"page":"1",
"totalpages":"1",
"total":"2"
}
}
}) // the object gets wrapped with extra parenthesis here
Instead of doing that I think you should be using the callbackKey: 'callback' that comes with the example in http://dev.sencha.com/deploy/touch/examples/ajax/index.js.
Something like this for example:
Ext.util.JSONP.request({
url: 'http://ws.audioscrobbler.com/2.0/',
params: {
method: 'geo.getEvents',
location: 'Sao+Paulo,+Brazil',
format: 'json',
api_key: 'b25b959554ed76058ac220b7b2e0a026'
},
callbackKey: 'callback',
callback: function(result) {
// Output result to console (Firebug/Chrome/Safari)
console.log(result);
// Handle error logic
if (result.error) {
alert(result.error)
return;
}
// Continue your code
var events = result.data.events;
// ...
}
});
That worked for me so hopefully it'll work for you too. Cherio.
