Create TinyURL via Jquery Ajax call

问题

I've looked through simiilar questions on SO, but can't seem to find one addressing what seems like a simple call..

function TweetThis(url)
{
    $.ajax({
      url: "http://tinyurl.com/api-create.php?url=" + url,
      cache: false,
      success: function(data){
       alert(data);
      }
    });
}

Basically I want to call TinyURL with an Ajax call and a long URL and return the shortened URL.. The success never fires, but when I check the URL it builds it returns fine in a browser.

Looking in Firebug it doesn't show response coming back.. what am I missing?

回答1:

Attempting to make a regular AJAX request is impossible because of same origin policy restrictions. Luckily there's a JSONP API courtesy of Remy Sharp.

Here's working code:

function TweetThis(bigurl)
{
    $.getJSON(
      "http://json-tinyurl.appspot.com/?&callback=?",
      {url: bigurl},
      function(data){
       alert(data.tinyurl);
      }
    );
}

回答2:

never used it, but maybe worth checking out. http://tiny-url.info/open_api.html

If you have ability to add logic to the server side, you can avoid the requirement for JSONP by installing a "shim" or gateway script that does what you want, and returns a formatted JSON string.

some examples of scripts that produce tinyurls by calling tinyurl.com's API:

PHP.
ASP classic
ASPNET Handler (ASHX) in C#
Python/CGI

Anyone can take that code and host it themselves to allow webpages to gain access to the tinyurl service. The same approach works for any service that is not accessible via JSONP.

In Safari 4 (Mac OS X), it works fine.
In Firefox 3 (Mac OS X), it half works - a alert dialog comes up, but it's empty (so success is firing, but no data is returned).
It seems to be a Firefox bug then.

Try this one.

The script:

<script language="javascript" type="text/javascript">
<!-- 
var ajaxRequest;  // The variable that makes Ajax possible!

    try{
        // Opera 8.0+, Firefox, Safari
        ajaxRequest = new XMLHttpRequest();
    } catch (e){
        // Internet Explorer Browsers
        try{
            ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
            try{
                ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e){
                // Something went wrong
                alert("Your browser is very old!");
            }
        }
    }

//Browser Support Code
function ajaxGetTiny(){

    // Create a function that will receive data sent from the server
    ajaxRequest.onreadystatechange = function(){
        if(ajaxRequest.readyState == 4){
            var ajaxDisplay = document.getElementById('ajaxDisplayTiny');
            ajaxDisplay.innerHTML = ajaxRequest.responseText;

        }
    }
        var long_url = document.getElementById('long_url').value;


    var queryString = "?long_url=" + long_url;
    ajaxRequest.open("GET", "getTiny.php" + queryString, true);
    ajaxRequest.send(null); 

}

function ClipBoard() 
{
holdtext.innerText = copytext.innerText;
Copied = holdtext.createTextRange();
Copied.execCommand("Copy");
}
//-->

</script>

Now the form:

<form name='myForm'>
      <input name="long_url" type="text" class="main" size="90">
      <br>
        <input type='button' class="Buttons" onclick='ajaxGetTiny();' value='GET TINY' />
      </form>

Now the helper file:

<? 
//gets the data from a URL  
function get_tiny_url($url)  {  
    $ch = curl_init();  
    $timeout = 5;  
    curl_setopt($ch,CURLOPT_URL,'http://tinyurl.com/api-create.php?url='.$url);  
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);  
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);  
    $data = curl_exec($ch);  
    curl_close($ch);  
    return $data;  
}

//test it out!
$new_url = get_tiny_url($_GET['long_url']);

?>
<link href="../styles.css" rel="stylesheet" type="text/css" />


<table width="100%" border="0" class="main">
<tr>
            <td width="5%" align="left" valign="middle"><strong>longURL:</strong></td>
            <td width="95%" valign="middle" class="ArticleBody"><? echo $_GET['long_url']; ?></td>
  </tr>
          <tr>
            <td align="left" valign="middle"><strong>tinyURL:</strong></td>
            <td valign="middle" class="ArticleBody"><SPAN ID="copytext"><? echo $new_url; ?></SPAN> 
            <TEXTAREA ID="holdtext" STYLE="display:none;"></TEXTAREA><br>
            <BUTTON onClick="ClipBoard();">Copy to Clipboard</BUTTON>
</td>
  </tr>
        </table>

回答5:

Have you tried adding &callback=? to the end of the URL? It could be the browser security getting in the way.

回答6:

This should work

function TweetThis(url){
    $.get(
        "http://tinyurl.com/api-create.php",
        {url: url},
        function(data){
            alert(data);
        }
    );
}
