How to send data in HTTP POST request while calling a url?
Question
I wrote a simple jsp page where I am loading an external website inside one of my division.
Below is the code :
<html>
<head>
<script src="../common/jquery-1.6.2.min.js"></script>
<script>
$(document).ready(function(){
$("#menu").html('<object data="www.someurl.com">').appendTo('body');;
});
</script>
</head>
<body>
<div id="menu" style="position:relative; bottom: 0; overflow:hidden;">
</div>
</body>
</html>
Basically what I am doing is that , I am setting an HTML content having a src URL inside the object tag. This is successful and I can load web URL inside my division.
Question comes when I want to send some data(may be a single variable) using HTTP POST method.
Is there any way to call the same URL using HTTP POST ?
Note : Here I cannot use Jquery POST because of same origin policy.

Take a look at the Jquery post function: http://api.jquery.com/jQuery.post/
Also, if you want to send some data, along with the url, you can do it with your get as well:
www.someurl.com?dataAttr=someValue&dataOtherAttr=someOtherDataValue
This would be the GET equivalent of a post with the following data:
{
"dataAttr": "someValue",
"dataOtherAttr": "someOtherDataValue"
}
Here is a pure js that will make a post to a server. The script makes an invisible iframe and makes a call to a specified server with the specified parameters. The server has to support the Cross Domain Policy. If you can't make the server support CORS, you are out of luck:
/**
*
* Makes a post to the specified url with the specified param - keyval
*/
makePost = function makePost(url, params){
var iframeId = 'iframeid';
var addParamsToForm = function (form, params){
var addParamToForm = function(form, paramName, paramValue){
var input = document.createElement('input');
input.hidden = 'hidden';
input.name = paramName;
input.value = paramValue;
form.appendChild(input);
}
for ( var prop in params ){
if ( params.hasOwnProperty(prop) ){
if ( params[prop] instanceof Array ){
for ( var i = 0; i < params[prop].length; i ++ ){
addParamToForm(form, prop, params[prop][i]);
}
} else {
addParamToForm(form, prop, params[prop]);
}
}
}
};
var iframe = document.getElementById(iframeId);
if ( iframe === null ){
iframe = document.createElement('iframe');
iframe.name = 'iframeName';
iframe.id = iframeId;
iframe.setAttribute("style", "width: 0; height: 0; border: none; display: none;");
}
var form = document.createElement('form');
form.action = url;
form.method = 'POST';
form.target = iframe.name;
addParamsToForm(form, params);
iframe.appendChild(form);
document.getElementsByTagName('body')[0].appendChild(iframe);
form.submit();
}
example usage:
makePost('yourserver', {'someAttr':'someAttrValue', 'someOtherAttr': 'someOtherAttrValue'});
Or a jquery variant:
$.ajax({
type: 'POST',
url: 'yourserver',
crossDomain: true,
data: {'someAttr':'someAttrValue', 'someOtherAttr': 'someOtherAttrValue'},
dataType: 'json',
success: function(responseData, textStatus, jqXHR) {
var value = responseData.someKey;
},
error: function (responseData, textStatus, errorThrown) {
alert('POST failed.');
}
});

Try to load the external link or website in an Iframe and try.
<div>
<iframe id="" name="" src="your external link" ></iframe>
</div>

I dont know if you an use php,becouse of the no php tag,but you can post data using HttpRequest class in php,and it is secured ! here is a link : http://php.net/manual/en/class.httprequest.php
