使用Services_Digg2與PHP的URL獲取Digg的計數

Question

有人可以在這方面的信息，目前還不清楚，如果這個api甚至能夠通過網址搜索，搜索谷G，沒有太多的成功。

關於新Services_Digg2梨包中的一些信息：

Answer 1

Services_Digg2只是一個客戶端庫在PHP轉發到API的所有調用和API不支持通過網址搜索。你需要傳遞的是網址的md5哈希值，而不是實際的網址。 PHP有一個md5函數，您可以使用它來獲取url的md5哈希值。

然後，API調用將用於story.getAll，並且您將先前計算的md5散列作爲參數link_hash傳遞。

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

上面這哈希是針對URL http://www.nytimes.com/2010/01/05/health/05docs.html和來自API的響應是：

<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> 

在此響應故事元素有一個名爲diggs的屬性，是你所需要的。

要通過PHP庫得到這個，代碼應該是這個樣子：

$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']; 
}
