WebSync Version 2 Docs


Overview
Clients
Publishers
Proxies

WebSync publishers can publish data without having to maintain an active connection. They are intended for server-side integration.

.NET Publisher

Getting Started

If you haven't already:

  1. Download the latest copy of WebSync On-Demand .NET.
  2. Add a reference to the downloaded library to your project.

You're ready to start coding!

Using the Publisher

To create a publisher, simply instantiate an instance of Publisher: 

// WebSync On-Demand Only
Publisher publisher = new Publisher(
    "11111111-1111-1111-1111-111111111111", // replace with your domain key
    "mydomain.com"                          // replace with your domain name
);

// WebSync Server Only
Publisher publisher = new Publisher(
    "http://mydomain.com/request.ashx"      // replace with your request handler
);

For WebSync Server, direct publishing over HTTP must be enabled server-side.

After creating a new publisher, make calls to Publish as necessary. The outgoing string parameter of Publish is empty if all publications were successful. It contains an array of JSON objects with successful and error properties if at least one of the publications failed.

Example

// create the publisher
// use your domain key and name here (if using WebSync On-Demand)
Publisher publisher = new Publisher(
    "11111111-1111-1111-1111-111111111111",
    "mydomain.com"
);

// publish data
string result;
bool success = client.Publish(new Publication[] {
    new Publication() {
        Channel = "/test",
        Data = "{\"text\":\"Hello, world!\"}"    // must be valid JSON
    },
    new Publication() {
        Channel = "/test",
        Data = "{\"text\":\"Hello, universe!\"}" // must be valid JSON
    }
}, out result);

PHP Publisher

Getting Started

If you haven't already:

  1. Download the latest copy of WebSync On-Demand PHP.
  2. Include a reference to 'Publisher.php' in your script.

You're ready to start coding!

Using the Publisher

To create a publisher, simply instantiate an instance of Publisher: 

// WebSync On-Demand Only
$publisher = new Publisher(
    "11111111-1111-1111-1111-111111111111", // replace with your domain key
    "mydomain.com"                          // replace with your domain name
);

// WebSync Server Only
$publisher = new Publisher(
    "http://mydomain.com/request.ashx"      // replace with your request handler
);

After creating a new publisher, make calls to publish, passing your publication(s). The string returned the method is empty if all publications were successful. It contains an array of JSON objects with successful and error properties if at least one of the publications failed.

The publish method takes either a single publication or an array of publications. Each publication is an associative array with channel and data properties:

  • channel (string)
    The name of the channel to which the client should publish.
  • data (object)
    The data to publish (a single serializable object).

Example

// create the publisher
// use your domain key and name here (if using WebSync On-Demand)
$publisher = new Publisher(
    "11111111-1111-1111-1111-111111111111",
    "mydomain.com"
);

// publish data
$response = $publisher->publish(array(
	array(
		'channel' => '/test',
		'data' => (object) array(
			'text' => 'Hello, world!'
		)
	),
	array(
		'channel' => '/test',
		'data' => (object) array(
			'text' => 'Hello, universe!'
		)
	)
));

// success if empty (no error)
$success = empty($response);

HTTP Publishing

It is possible to publish from any language with HTTP support (.NET, Java, PHP, Python, Ruby, etc.) by sending a GET or POST request.

Using GET

Publish messages by sending an HTTP request with a method type of GET to: 

// WebSync On-Demand Only
http://sync.frozenmountain.com/request.ashx?key=KEY&publications=PUBLICATIONS

// WebSync Server Only (replace with your request handler)
http://mydomain.com/request.ashx?publications=PUBLICATIONS
  • For WebSync On-Demand only, replace KEY with your public or private domain key.
  • Replace PUBLICATIONS with a URL-encoded array of publications in JSON format.
  • Set the referrer of the GET request to your fully-qualified domain, including an http:// prefix.

Be cautious of size limitations! Local proxies often enforce a limit on the query string length and may truncate your publications. If your submission is larger than 1-2 KB, we recommend using POST instead.

C# Example: 

// prepare our publications in valid JSON
string publications = HttpUtility.UrlEncode(
    "[{\"channel\":\"/test\",\"data\":{\"text\":\"Hello, world!\"}}]"
);

// create the request
// use your domain key here (if using WebSync On-Demand)
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(
    "http://sync.frozenmountain.com/request.ashx" +
    "?key=11111111-1111-1111-1111-111111111111" +
    "&publications=" + publications
);

// set request options
// use your domain here (if using WebSync On-Demand)
request.Referer = "http://mydomain.com";
request.Method = "GET";

// get response
string response = "";
using (Stream respStream = request.GetResponse().GetResponseStream())
using (StreamReader respReader = new StreamReader(respStream))
    response = respReader.ReadToEnd();

// success if empty (no error)
bool success = (string.IsNullOrEmpty(response));

PHP Example: 

// prepare our publications in valid JSON
$publications = urlencode(
    "[{\"channel\":\"/test\",\"data\":{\"text\":\"Hello, world!\"}}," +
    "{\"channel\":\"/test\",\"data\":{\"text\":\"Hello, universe!\"}}]"
);

// create the request
// use your domain key here (if using WebSync On-Demand)
$ch = curl_init(
    "http://sync.frozenmountain.com/request.ashx" +
    "?key=11111111-1111-1111-1111-111111111111" +
    "&publications=$publications"
);

// set request options
// use your domain here (if using WebSync On-Demand)
curl_setopt($ch, CURLOPT_REFERER, "http://mydomain.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

// get response
$response = curl_exec($ch);
curl_close($ch);

// success if empty (no error)
$success = empty($response);

Using POST

Publish messages by sending an HTTP request with a method type of POST to: 

// WebSync On-Demand Only
http://sync.frozenmountain.com/request.ashx?key=KEY

// WebSync Server Only (replace with your request handler)
http://mydomain.com/request.ashx
  • For WebSync On-Demand only, replace KEY with your public or private key.
  • Set the content-type to application/json.
  • Set the referrer of the POST request to your fully-qualified domain, including an http:// prefix.

POST is more reliable for large data publications as it does not have the size limitations of GET.

C# Example: 

// prepare our publications in valid JSON
string publications =
    "[{\"channel\":\"/test\",\"data\":{\"text\":\"Hello, world!\"}}]";

// create the request
// use your domain key here (if using WebSync On-Demand)
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(
    "http://sync.frozenmountain.com/request.ashx" +
    "?key=11111111-1111-1111-1111-111111111111"
);

// set request options
// use your domain here (if using WebSync On-Demand)
request.Referer = "http://mydomain.com";
request.Method = "POST";
request.ContentType = "application/json";

// write POST data
using (Stream reqStream = request.GetRequestStream())
using (StreamWriter reqWriter = new StreamWriter(reqStream))
    reqWriter.Write(publications)

// get response
string response = "";
using (Stream respStream = request.GetResponse().GetResponseStream())
using (StreamReader respReader = new StreamReader(respStream))
    response = respReader.ReadToEnd();

// success if empty (no error)
bool success = (string.IsNullOrEmpty(response));

PHP Example: 

// prepare our publications in valid JSON
$publications =
    "[{\"channel\":\"/test\",\"data\":{\"text\":\"Hello, world!\"}}," +
    "{\"channel\":\"/test\",\"data\":{\"text\":\"Hello, universe!\"}}]";

// create the request
// use your domain key here (if using WebSync On-Demand)
$ch = curl_init(
    "http://sync.frozenmountain.com/request.ashx" +
    "?key=11111111-1111-1111-1111-111111111111"
);

// set request options
// use your domain here (if using WebSync On-Demand)
curl_setopt($ch, CURLOPT_REFERER, "http://mydomain.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json"));

// write POST data
curl_setopt($ch, CURLOPT_POSTFIELDS, $publications);

// get response
$repsonse = curl_exec($ch);
curl_close($ch);

// success if empty (no error)
$success = empty($response);
