目前还不清楚这个 API 是否能够通过 URL 进行搜索，通过 G 进行搜索，但没有取得太大成功。

Services_Digg2 只是 PHP 中的一个客户端库，它将所有调用转发到 API，并且 API 确实支持按 url 搜索。您需要传递的是 url 的 md5 哈希值，而不是实际的 url。 PHP 有一个 md5 函数，您可以使用它来获取url 的 md5 哈希值。

然后，API 调用将针对 story.getAll，并且您将之前计算的 md5 哈希值作为参数 link_hash 传递。

http://services.digg.com/1.0/endpoint?method=story.getAll&link_hash=a23658a0828e2fb388b7c83f61e235e6

上面的哈希值适用于 URL http://www.nytimes.com /2010/01/05/health/05docs.html 并且来自 API 的响应是：

<stories timestamp="1262740374" total="1" offset="0" count="1"> 
 <story link="http://www.nytimes.com/2010/01/05/health/05docs.html" submit_date="1262729293" diggs="70" id="18288654" comments="6" href="http://digg.com/health/For_F_D_R_Sleuths_New_Focus_on_an_Odd_Spot" promote_date="1262739603" status="popular" media="news"> 
  <description>Look closely at Roosevelt’s portraits over his 12-year presidency. In his first two terms, there is a dark spot over his left eyebrow. It seems to grow and then mysteriously vanishes sometime around 1940, leaving a small scar.  </description>

  <shorturl short_url="http://digg.com/d31EjiI" view_count="192" /> 
 </story> 
</stories>

此响应中的 Story 元素有一个名为 diggs 的属性，这正是您所需要的。

要通过 PHP 库实现此目的，代码应如下所示：

$url = "...";

$api = new Services_Digg2;
$stories = $api->story->getAll(array('link_hash' => md5($url)))->stories;

foreach($stories as $story) {
    // I am not sure how to access the diggs attribute
    // Maybe this works. If not, just
    // var_dump the $story object and 
    // see how to access the digg count information.
    echo $story['diggs'];
}

Services_Digg2 is just a client library in PHP that forwards all calls to the API and the API does support searching by urls. What you need to pass is the md5 hash of the url instead of the actual url. PHP has a md5 function that you can use to get the md5 hash of a url.

The API call then would be for story.getAll and you pass the previously calculated md5 hash as a parameter link_hash.

http://services.digg.com/1.0/endpoint?method=story.getAll&link_hash=a23658a0828e2fb388b7c83f61e235e6

This hash above is for the URL http://www.nytimes.com/2010/01/05/health/05docs.html and the response from the API is:

<stories timestamp="1262740374" total="1" offset="0" count="1"> 
 <story link="http://www.nytimes.com/2010/01/05/health/05docs.html" submit_date="1262729293" diggs="70" id="18288654" comments="6" href="http://digg.com/health/For_F_D_R_Sleuths_New_Focus_on_an_Odd_Spot" promote_date="1262739603" status="popular" media="news">

  <shorturl short_url="http://digg.com/d31EjiI" view_count="192" /> 
 </story> 
</stories>

The story element in this response has an attribute called diggs which is what you need.

To get this through the PHP library, the code should look something like:

$url = "...";

$api = new Services_Digg2;
$stories = $api->story->getAll(array('link_hash' => md5($url)))->stories;

foreach($stories as $story) {
    // I am not sure how to access the diggs attribute
    // Maybe this works. If not, just
    // var_dump the $story object and 
    // see how to access the digg count information.
    echo $story['diggs'];
}
