Hiya,
Due to the undocumented nature of the Amazon SNS endpoints and how they interact with the user, I am struggling to code an endpoint in Sinatra for my application.
I have some code written in PHP here, but I am struggling to convert it into a Ruby array because request.env["rack.input"].read encapsulates everything into something similar to a PHP array:
{"Message"=>"chapstick", "Subject"=>"cherry", "Signature"=>"QutYUXuqWQqiAY4PUvd+Hq+9KWSvPVwck22oV0pXkgSg0p+kZ/2Q+pS24siDPKxxHB8+ru5q6 QBqQv+RHKWobiLiupEf4UP1MQu3lnP4Z2TYWvbHVjNiO5OutcaivPrn08EIBTOMsWl2i8JmaTBXozOp4r1vheqg6k/wWDoUmd0=", "TopicArn"=>"arn:aws:sns:us-east-1:687180262489:plinklebird", "SignatureVersion"=>"1", "Timestamp"=>"2010-12-03T22:10:01.141Z", "MessageId"=>"dc8a8502-44a8-41ec-9616-1d049f00724d", "UnsubscribeURL"=>"https://sns.us-east-1.amazonaws.com/?Action=Unsubscribe&SubscriptionArn=arn:aws:sns:us-east-1:687180262489:plinklebird:99e83fd5-58a9-41bb-82bd-9920a1ee1a94", "Type"=>"Notification"}
I am not sure how to handle this, can anybody please help?
Thank you very much for your time,
Luke Carpenter
A year and four months later, reflecting on this problem:
It was because I was a complete and utter noob, and I didn't know what a Hash was in Ruby at the time
In your post block, access the contents of the hash like so:
post "/" do
puts params['Message']
halt 200
end
The message SNS sends you will be printed out to STDOUT/your terminal

I'm trying to use LOAD CSV with a CSV file stored in GitHub. It works fine with the 10 minute, temporary token you get when viewing the raw file, but I want something that's more persistent, as I need to be able to deploy this to multiple environments. Ten minutes just won't cut it.
I figured a private access token would be the way forward, but (once again) GitHub's spectacularly poor quality documentation made this much harder than it should be.
I set up a private access token with the repo and read:org permissions and with this I can get at my files using CURL, e.g.
curl -s https://<my_token>#raw.githubusercontent.com/<my repo>/<path>/<my file>.csv
This works fine and I see the contents of my test file.
But if I try to navigate to that URL I just get a 404 error and if I use it in Neo4j with a LOAD CSV statement, I get an error couldn't load the external resource at:.
I'm basically doing this:
LOAD CSV WITH HEADERS FROM '<URL that worked in CURL>' AS row
...and it fails miserably.
Where:
LOAD CSV WITH HEADERS FROM '<URL for raw file from GitHub with 10 minute token>' AS row
works fine, so I know I can access external files, i.e. files not in the import directory.
Is this just a failing with GitHub, or am I doing something wrong?
Although I hate answering my own questions, I left this kicking around a while and nobody came back with anything that helped.
I now know a whole lot more about public access tokens than I ever wanted to, but it was all worthwhile, as it helped me get around this issue.
There's an apoc.load.jsonParams function that accepts bearer tokens. From here it didn't take too much work to get this working the same way that LOAD CSV had done.
There was one last gotcha though, I soon discovered that the URLs for the repository can't include spaces or other non-alphanumeric characters, but that's a small price to pay for success?
So this doesn't work:
LOAD CSV WITH HEADERS FROM 'https://<my_token>#raw.githubusercontent.com/<my repo>/<path>/<my file>.csv' AS row...
Instead I had to use:
CALL apoc.load.jsonParams("https://raw.githubusercontent.com/<my repo>/<path>/<my file>.json", {Authorization: "Bearer <token>"}, null) YIELD value WITH value AS row...
There's an equivalent apoc.load.csvParams procedure, but I never tested this.
I want to send some "raw" RPC commands
For example;
<rpc>
<open-configuration>
<ephemeral-instance>eph1</ephemeral-instance>
</open-configuration>
</rpc>
]]>]]>
im a bit baffled on how to do that, any thoughts?
Something like
with Config(dev, mode='ephemeral', ephemeral_instance='eph1') as cu:
cu.load('set protocols mpls label-switched-path to-hastings to 192.0.2.1', format='set')
cu.commit()

First off thanks for reading!
Second off YES I have tried to find the answer! :) Perhaps I haven't found it because I'm not using the right words to describe my problem, but it's been about 4 hours that I've been trying to figure it out now and I'm getting a little loopy trying to piece it together on my own.
I am very new to programming. Python is my first language. I am on my third Python course. I have an assignment to use the socket library (not urllib library - I know how to do that) to make a socket and use GET to receive information. The problem is that the program needs to take raw input for the URL in question.
I have everything else the way I want it, but I need to know the syntax that I'm supposed to be using INSIDE my "GET" request in order for the HTTP message to include the requested document path.
I have tried (obviously not all together lol):
mysock.send('GET (url) HTTP/1.0\n\n')
mysock.send( ('GET (url) HTTP:/1.0\n\n'))
mysock.send(('GET (url) HTTP:/1.0\n\n'))
mysock.send("GET (url) HTTP/1.0\n\n")
mysock.send( ("'GET' (url) HTTP:/1.0\n\n"))
mysock.send(("'GET' (url) 'HTTP:/1.0\n\n'"))
and:
basically every other configuration of the above (, ((, ( (, ', '' combinations listed above.
I have also tried:
-Creating a string using the 'url' variable first, and then including it inside mysock.send(string)
-Again with the "string-first" theory, but this time I used %r to refer to my user input (so 'GET %r HTTP/1.0\n\n' % url basically)
I've read questions here, other programming websites, the whole chapter in the book and the whole lectures/notes online, I've read articles on the socket library and the .send(), and of course articles on GET requests... but I'm clearly missing something. It seems most don't use socket library when they can use urllib and I don't blame them!!
Thank you again...
Someone from the university posted back to me that the url variable can concatenated with the GET syntax and assigned to a string variable which can then be called with .send(concatenatedvariable) - I had mentioned trying that but had missed that GET requires a space after the word 'GET' so of course concatenating didn't include a space and that blew it. In case anyone else wants to know :)
FYI: A fully quallified URL is only allowed in HTTP/1.1 requests. It is not the norm, though, as HTTP/1.1 requires setting the Host header. The relevant piece of reading would've been RFC 7230, sec. 3.1.1 and possibly RFC 3986. The syntax of the parameters is largely borrowed from the CGI format. It is in no way enforced, however. In a nutshell, everything put together would look like this on the wire:
GET /path?param1=value1¶m2=value2 HTTP/1.1
Host: example.com
As a final note: The line delimiter in HTTP is CRLF (\r\n). For robustness, a simple linefeed is acceptable as well but not recommended.
I need to access the Date: header when I handle the request, but this seems to be "swallowed" by the framework; any other header (even made up FooBar ones) show up and I can get them, but this gives me None (I'm using Postman to send a simple GET request - everything else works just fine):
println("Date: " + request.headers.get("Date").getOrElse("no date!"))
returns "no date!" no matter how I try to send something sensible.
I'm wondering whether this gets processed before the request object reaches my Action.
I need the actual string value sent, as this should be part of the request's signature - so an equivalent Date object representing the same value would not be of much use (as it needs to be part of the hash, to avoid replay attacks).
Just as a test, I replaced the Date header with a Date-Auth one, and this one shows up just fine:
ArrayBuffer((Date-Auth, ArrayBuffer(Wed, 15 Nov 2014 06:25:24 GMT))
Any ideas or suggestions greatly appreciated!
Are you sure there is a Date Header in your request (tested with tools like firebug or wireshark)?
Browsers do not need to send a Date header.
RFC 2616 (HTTP 1.1) from the Date section (14.18)
Clients SHOULD only send a Date header field in messages that include an entity-body, as in the case of the PUT and POST requests, and even then it is optional. A client without a clock MUST NOT send a Date header field in a request.
I stand corrected - it turns out that Chrome blocks a whole bunch of headers:
http://www.getpostman.com/docs/requests
I wrote a Python Flask test server and, in fact, the Date header is not there.
That page has also a fix, which works just fine with Postman Version 0.10.4.3 and Interceptor(1).
sorry for wasting everyone's time!
1 Incidentally, IMO Postman is the best REST client and has now also some awesome looks, beyond incredible functionality. If you're working with REST APIs, I highly recommend it.
I need tips to build an infrastructe to send 1000 simultaneous voice calls (automated IVR calls with voicexml). Up to now i used asterisk with voiceglue but now i have performance issues.
The infrasturcture was like this:
the asterisk pulls request from queue
the queue consumer create a call file
when the call ends, call file is read and status is sent to the application server
To be honest, i am asking for tips to implement an infrastructure like callfire[1] or voxeo[2]?
[1]https://www.callfire.com/
[2]http://voxeo.com/
you can go with voxeo prophecy (http://voxeo.com/prophecy/) one of the good server which have the capability of making simultaneous voice calls
Note: The requirement which your are expecting to do will not only possible with voxeo prophecy it should also depend the web server like Tomcat, IIS e.t.c in case if you dealing with databases like Sql , Oracle e.t.c
Please do refer to know the architecture
http://www.alpensoftware.com/define_VoiceOverview.html
CallFire's API has a CreateBroadcast method where you can throw up an IVR using their XML in seconds. You can read up on the documentation here:
https://www.callfire.com/api-documentation/rest/version/1.1#!/broadcast
CallFire also offers a PHP-SDK, hosted on Github, with examples of how to do this. The SDK is minimal setup and allows you to easily tap into the APIs robust functionality. Version 1.1 can be found here, with instructions on how to get started: https://github.com/CallFire/CallFire-PHP-SDK
The method call might look something like this. Note the required dependencies.
<?php
use CallFire\Api\Rest\Request;
use CallFire\Api\Rest\Response;
require 'vendor/autoload.php';
$dialplan = <<<DIALPLAN
<dialplan><play type="tts">Congratulations! You have successfully configured a CallFire I V R.</play></dialplan>
DIALPLAN;
$client = CallFire\Api\Client::Rest("<api-login>", "<api-password>", "Broadcast");
$request = new Request\CreateBroadcast;
$request->setName('My CallFire Broadcast');
$request->setType('IVR');
$request->setFrom('15551231234'); // A valid Caller ID number
$request->setDialplanXml($dialplan);
$response = $client->CreateBroadcast($request);
$result = $client::response($response);
if($result instanceof Response\ResourceReference) {
// Success
}
You can read this:
http://www.voip-info.org/wiki/view/Asterisk+auto-dial+out
Main tip: you WILL have ALOT of issues. If you are not expert with at least 5 years development experience with asterisk, you have use already developed dialling cores or hire guru. There are no opensource core that can do more then 300 calls on single server.
You can't do 1000 calls on single asterisk in app developed by "just nice developer". It will just not work.
Task of create dialling core for 1000 calls is "rocket science" type task. It require very special dialling core, very special server/server tunning and very specialized dialler with pre-planning.
1000 calls will result 23Mbit to 80Mbit bandwidth usage with SMALL packets, even that single fact can result you be banned on your hosting and require linux network stack be tunned.
You can use ICTBroadcast REST API to integerate your application with reknown autodialer , please visit following link for more detail
http://www.ictbroadcast.com/news/using-rest-api-integerate-ictbroadcast--third-party-application-autodialer
ICTBroadcast is based on asterisk communication engine
I've already done this for phone validation and for phone message broadcasting using Asterisk and Freeswitch. I would go with Freeswitch and xmlrpc:
