How to handle REST API call for GET Verb

Dear pals,

I am newbie in RESTful services . I need to call a GET Verb in Server . I know 2 methods

1. Ajax Call

we can write it as

Code:

$.ajax({
         url: url, 
         dataType: "html",
         type: 'POST', 
         data: "id="+id+"&type="+type, 
         success: function(data){ 
		    //$("#content").html(data); 
			alert(data);
			$('table #sample-boxed-2-pagination th a').each(function(){
				//this.href = this.href.replace(sub_url, main_url);
				var value = this.href.split('?');
				//alert(value[0]);
				if(value[0]!=sub_url)
				{
				  this.href = this.href.replace(value[0], sub_url);
				}
      });
         }
		 
		 
      });		 
});

But I know it's not working in Cross domain scenario . Please advise a method to work same in all domains .

2. Using file_get_contents() function like

Code:

$response = file_get_contents('<url>?parm1=9');

I know I can call POST verb using cURL as

Code:

$ch = curl_init();

	curl_setopt($ch, CURLOPT_URL, "<base_url>/simple_rest_master/test");
	curl_setopt($ch, CURLOPT_HEADER, 0);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_POST, 1);


	$data = array(
		'username' => 'foo',
		'password' => 'bar'
	);

	curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

	$contents = curl_exec($ch);

	curl_close($ch);
	
	echo $contents;  // manipulate response

Do you can advise the syntax of GET call using cURL ?

Waiting your fast reply

Thanks,
