如何获得使用Services_Digg2一个URL的Digg的计数?
题
目前尚不清楚,如果此API甚至能够通过URL搜索的,至G搜索,但没有成功。
解决方案
Services_Digg2只是在PHP客户端库,所有呼叫转发到API及API不支持网址搜索。你需要传递的是URL,而不是实际的URL的MD5哈希值。 PHP有一个,你可以用它来获得MD5 功能一个URL的MD5哈希值。
在API调用然后将是story.getAll
和传递先前计算的MD5哈希作为参数link_hash
。
http://services.digg.com/1.0/endpoint?method=story.getAll&link_hash=a23658a0828e2fb388b7c83f61e235e6
以上该散列是用于URL 的http:// WWW。 nytimes.com/2010/01/05/health/05docs.html 和从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>
在此响应的故事元素有一个名为diggs
的属性,是你所需要的。
要通过PHP库得到这个,代码看起来应该是这样的:
$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'];
}
