Hello my fellow ColdFusion developers!
I'm trying to learn node.js, and I have a free sandbox account at http://pusher.com/.
If I view the API access, they give pastable html code:
<!DOCTYPE html>
<head>
<title>Pusher Test</title>
<script src="http://js.pusherapp.com/1.9/pusher.min.js" type="text/javascript"></script>
<script type="text/javascript">
// Enable pusher logging - don't include this in production
Pusher.log = function(message) {
if (window.console && window.console.log) window.console.log(message);
};
// Flash fallback logging - don't include this in production
WEB_SOCKET_DEBUG = true;
var pusher = new Pusher('0xxxx0xxxxxxxxxxxx00');
var channel = pusher.subscribe('test_channel');
channel.bind('my_event', function(data) {
alert(data);
});
</script>
</head>
and I have pasted that into a web page.
Then they give some code to send via curl:
curl -d "hello world" \
"http://api.pusherapp.com/apps/7499/channels/test_channel/events?"\
"name=my_event&"\
"body_md5=xxxxxxxxxxxxxxxxx&"\
"auth_version=1.0&"\
"auth_key=0xxxxxxxxxxxxxxx00&"\
"auth_timestamp=1318305150&"\
"auth_signature=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
but I don't think I have curl.
Q: Can I use cfhttp instead?
I have no idea what is going on here. NodeJS is not your web browser. I do not see how NodeJS relates to any of this.
I never used pusher or coldfusion before, but I am sure you can use ColdFusion to send simple HTTP requests to "pusher", just like curl. HTTP requests are not complicated at all, and curl is a simple command line program that sends and receives them.
The curl command is just opening that long URL as POST request, and sending "hello world" as the body, and "hello world" should appear in your web browser.

I am trying to embed an AWS Quicksight dashboard into our application but I am having some trouble with the embed process. The URL has been generated correctly and but I get a permission denied error when I attempt to embed it.
I am able to load the generated URL directly in a new tab but when I attempt to embed it I get a 401 error.
I have whitelisted the domain in the Quicksight console and am accessing the page over HTTPS. The complete test page is shown below.
The following code is what I am using to test embedding. It was taken from an Amazon example.
<!DOCTYPE html>
<html>
<head>
<title>My Dashboard</title>
<script src="https://unpkg.com/amazon-quicksight-embedding-sdk/dist/quicksight-embedding-js-sdk.min.js" ></script>
<script type="text/javascript">
function embedDashboard() {
var containerDiv = document.getElementById("dashboardContainer");
var params = {
url: "<link that works in a standalone browser tab>",
container: containerDiv,
parameters: {
},
height: "700px",
width: "1000px"
};
var dashboard = QuickSightEmbedding.embedDashboard(params);
dashboard.on('error', function(err) {console.log('dashboard error:', err)});
dashboard.on('load', function() {});
}
</script>
</head>
<body onload="embedDashboard()">
<div id="dashboardContainer"></div>
</body>
</html>
Amazon sends a 302, followed by a 401. Which results in a frame with the error message "We can't display this page (Not Authorized).
The first request in the image fetches a fresh link from the server and the subsequent two are the framing attempt.
I would expect that if something was wrong with my authorization then a loading the link in it's own tab would not work. I think the issue must be with the frame but don't know what other options to check beyond the whitelist.
Does anyone have any idea what else I can try?
This is a single script.php only to load data.

In Mac Safari I get I get `SyntaxError: Unexpected token ':'. Parse error.
Several data is loaded I see it in Safari debugger starting in:
but I cannot use it because of that error message.
In Chrome and Opera I get Cross-Origin Read Blocking (CORB) blocked cross-origin response with MIME type application/json.
Reading some old questions I added
<?php header('Access-Control-Allow-Origin: http://example.com') ?>
and then replaced by
<?php header('Access-Control-Allow-Origin: *') ?>
as the first line but nothing changed.
From Google side: Key restrictions
-> Application restrictions: none.
-> API restrictions: yes (key is accepted for 4 APIs, one of them is Geocoding API
What's wrong here?
Since you are making a Geocoding web service request in the client-side (front-end) that's why you are getting the Cross-origin blocking error (CORB). Web service requests are meant to be executed server side.
Note that if you intend to use Geocoding in client-side, the JavaScript API has a Geocoding Service (which prevents the CORB issue). Please refer to this guide: https://developers.google.com/maps/documentation/javascript/geocoding
Hope this helps!
I can't seem to get any sample app working. I'm trying to run a simple websocket 101 starter app that does nothing more than log something to console.
I have cfws directory in my webroot C:\inetpub\wwwroot, and I'm working in C:\inetpub\wwwroot\site\.
I have enabled web sockets in the cfadmin, with "use proxy" option, port 8579.
The code I'm running is:
index.cfm:
<html>
<head>
<title>Example One</title>
<script language="javascript">
function messageHandler(msg) {
console.log("messageHandler Run");
console.dir(msg);
}
</script>
</head>
<body>
<h1>Example One</h1>
</body>
</html>
<cfwebsocket name="myWS" onMessage="messageHandler" subscribeTo="news">
Application.cfc
component {
this.name="cfwack2_1";
this.wschannels = [{name:"news"}];
}
I run the code and there are no errors, but I don't see the expected log in the console.
So far every sample app I've tried does five eighths of nothing. Any help appreciated.
You may have a typo in your Application.cfc. According to the docs here, it should look like this:
component {
this.name="cfwack2_1";
this.wschannels=[{name="news"}];
}
An = (equal sign) instead of a : (colon) after name.
The documentation also shows that the JavaScript function should accept an event and a token value. Here is the example from the documentation.
<script type="text/javascript">
function mymessagehandler(aevent, atoken)
{
var message = ColdFusion.JSON.encode(atoken);
var txt=document.getElementById("myDiv");
txt.innerHTML +=message +"";
}
</script>
<cfwebsocket name="mycfwebsocketobject" onmessage="mymessagehandler" subscribeto="news">
<cfdiv id="myDiv"></cfdiv>
I've just discovered CherryPy. I am going through the tutorial, so far so good. While doing it I wanted to create a "BUSY DOING WORK" splash screen, essentially I have a python function that for example updates an sqlite table with 10000 records. What I want to do is get CherryPy to display a busy.html page while the database is being updated, when the database operation completes I want to redirect the user back to the main.html page.
So far I have only come across
dev update_db(self):
#Code to update the database goes here
return "busy.html"<----show user that work is being done
#database has completed
CherryPy.redirect "main.html"
But return simply exits the function. Is there anyway of doing presenting the user with a temporary splashscreen, while the database is being updated then returning the user back to another page once its complete.
I suppose an alternative is to have a message flash across the top of the existing page, But I don't know if CherryPy has a flash message feature much like Flask.
IMHO, you can achieve this with generators and here is a link from latest (v3.8) cherrypy documentation. However, you should take into account the following issue in the docs
Streaming generators are sexy, but they play havoc with HTTP. CherryPy allows you to stream output for specific situations: pages which take many minutes to produce, or pages which need a portion of their content immediately output to the client. Because of the issues outlined above, it is usually better to flatten (buffer) content rather than stream content. Do otherwise only when the benefits of streaming outweigh the risks.
Generators have some limitations as written in the documentation
you cannot manually modify the status or headers within your page handler if that handler method is a streaming generator, because the method will not be iterated over until after the headers have been written to the client. This includes raising exceptions like HTTPError, NotFound, InternalRedirect and HTTPRedirect. To use a streaming generator while modifying headers, you would have to return a generator that is separate from (or embedded in) your page handler.
Because the headers have already been written to the client when streaming, raising redirection exception cannot help to redirect to different page after your long running task. If I were you, I would yield this
<meta http-equiv="refresh" content="0;URL='/anotherpage'" />
or this at the final yield
<script>window.location.href="/anotherpage";</script>
I coded and example for you. I hope this gives you an idea.

Im trying to implement oauth1 for quickbooks, using a python library requests_oauthlib. My problem is i tried setting up the quickbooks oauth as suggested by quickbooks inserting the quicbooks button.
The sample code provided was:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:ipp="">
<head><meta http-equiv="Content-Type"
content="text/html; charset=ISO-8859-1">
<title>My Connect Page</title>
<script type="text/javascript" src="https://appcenter.intuit.com/Content/IA/intuit.ipp.anywhere-1.3.2.js">
</script>
<script type="text/javascript">
intuit.ipp.anywhere.setup({
grantUrl: 'http://www.mycompany.com/HelloWorld/RequestTokenServlet'
datasources: {
quickbooks : true,
payments : false
},
paymentOptions:{
intuitReferred : true
}
});
</head>
<body>
<ipp:connectToIntuit></ipp:connectToIntuit>
</body>
</html>
But what it does is, it opens a new pop up like window and goes through the oauth process, but i am not able to figure out, how to get the control back to my app when the redirect happens to the redirect url mentioned, with the access token. Now the redirect url is also opened within the pop up window.
But what it does is, it opens a new pop up like window and goes through the oauth process,
This is expected behavior. This should happen. The entire OAuth process takes place within the pop-up.
Now the redirect url is also opened within the pop up window.
It should be, this is good.
All you have to do is use window.close() to close the pop-up once the OAuth process completes.
