<h1> Connection Manager GET Transaction</h1>
<p>
To construct a GET transaction using the Connection Manager, you will need to construct a querystring of key-value pairs and append it to the URL.
The following code example provides a step-by-step approach to creating a simple GET transaction.
</p>
<h3>Source file and dependencies</h3>
<p>Load the YAHOO namespace and connection manager source file:</p>
<pre><textarea name="code" class="JScript" cols="60" rows="1"><script src="yahoo.js"></script>
<script src="connection.js"></script></textarea></pre>
<h3>Assemble the Querystring</h3>
<p>Construct a querystring with two key-value pairs of <em>username = anonymous</em> and <em>userid = 0</em>:</p>
<pre><textarea name="code" class="JScript" cols="60" rows="1"> /*
*
* Create a querystring with example key-value pairs of
* username and userid. Remember to encode the querystring
* if and when the string contains special characters.
*
*/
var sUrl = "get.php?username=anonymous&userid=0";</textarea></pre>
<h3>The Callback Object</h3>
<p>Create a callback object to handle the response, and pass an object literal to both success and failure as the argument.</p>
<pre><textarea name="code" class="JScript" cols="60" rows="1">var handleSuccess = function(o){
function parseHeaders(){
var allHeaders = headerStr.split("\n");
var headers;
for(var i=0; i < headers.length; i++){
var delimitPos = header[i].indexOf(':');
if(delimitPos != -1){
headers[i] = "&lt;p&gt" +
headers[i].substring(0,delimitPos) + ":"+
headers[i].substring(delimitPos+1) + "&lt;/p&gt;";
}
return headers;
}
if(o.responseText !== undefined){
div.innerHTML = "Transaction id: " + o.tId;
div.innerHTML += "HTTP status: " + o.status;
div.innerHTML += "Status code message: " + o.statusText;
div.innerHTML += "HTTP headers: " + parseHeaders();
div.innerHTML += "Server response: " + o.responseText;
div.innerHTML += "Argument object: property foo = " + o.argument.foo +
"and property bar = " + o.argument.bar;
}
}
var callback =
{
success:handleSuccess,
failure: handleFailure
argument: { foo:"foo", bar:"bar" }
};</textarea></pre>
<h3>Initiate the GET Transaction</h3>
<p>Call YAHOO.util.Connect.asyncRequest to send the request to get.php,
and the PHP file will return the output of $_POST via <strong>print_r()</strong>.
The handleSuccess callback will print the response object's properties, including
the server response data.
</p>
<p>
Note: Caching and GET idempotency.
