Question

我想获得当前网页的Google + 1s数量？我想在PHP中执行此过程，然后将数量的共享或+ 1s写入数据库。这就是为什么，我需要它。那么，我怎样才能在PHP中完成这个过程（获得+ 1s的数量）？
提前谢谢。

Answer 1

这个适用于我，比CURL更快：

function getPlus1($url) {
    $html =  file_get_contents( "https://plusone.google.com/_/+1/fastbutton?url=".urlencode($url));
    $doc = new DOMDocument();   $doc->loadHTML($html);
    $counter=$doc->getElementById('aggregateCount');
    return $counter->nodeValue;
}

此处还有推文，引脚和Facebook

function getTweets($url){
    $json = file_get_contents( "http://urls.api.twitter.com/1/urls/count.json?url=".$url );
    $ajsn = json_decode($json, true);
    $cont = $ajsn['count'];
    return $cont;
}

function getPins($url){
    $json = file_get_contents( "http://api.pinterest.com/v1/urls/count.json?callback=receiveCount&url=".$url );
    $json = substr( $json, 13, -1);
    $ajsn = json_decode($json, true);
    $cont = $ajsn['count'];
    return $cont;
}

function getFacebooks($url) { 
    $xml = file_get_contents("http://api.facebook.com/restserver.php?method=links.getStats&urls=".urlencode($url));
    $xml = simplexml_load_string($xml);
    $shares = $xml->link_stat->share_count;
    $likes  = $xml->link_stat->like_count;
    $comments = $xml->link_stat->comment_count; 
    return $likes + $shares + $comments;
}

注意：Facebook数字是喜欢+分享的总和，有些人说加上评论（我还没有搜索过），无论如何都要使用你需要的那个。

如果你的php设置允许打开外部URL，这将有效，检查你的“allow_url_open”php设置。

希望有所帮助。

function get_plusones($url) {
  $curl = curl_init();
  curl_setopt($curl, CURLOPT_URL, "https://clients6.google.com/rpc");
  curl_setopt($curl, CURLOPT_POST, 1);
  curl_setopt($curl, CURLOPT_POSTFIELDS, '[{"method":"pos.plusones.get","id":"p","params":{"nolog":true,"id":"' . $url . '","source":"widget","userId":"@viewer","groupId":"@self"},"jsonrpc":"2.0","key":"p","apiVersion":"v1"}]');
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
  $curl_results = curl_exec ($curl);
  curl_close ($curl);
  $json = json_decode($curl_results, true);
  return intval( $json[0]['result']['metadata']['globalCounts']['count'] );
}

echo get_plusones("http://www.stackoverflow.com")

此处其他帖子中列出的cURL和API方式不再有效。

There is still at least 1 method，但它很难看，Google显然不支持它。您只需使用正则表达式从官方按钮的JavaScript源代码中删除变量：

function shinra_gplus_get_count( $url ) {
    $contents = file_get_contents( 
        'https://plusone.google.com/_/+1/fastbutton?url=' 
        . urlencode( $url ) 
    );

    preg_match( '/window\.__SSR = {c: ([\d]+)/', $contents, $matches );

    if( isset( $matches[0] ) ) 
        return (int) str_replace( 'window.__SSR = {c: ', '', $matches[0] );
    return 0;
}

到目前为止，下一个PHP脚本可以很好地检索Google+上的分数和+ 1。

$url = 'http://nike.com';
$gplus_type = true ? 'shares' : '+1s';

/**
 * Get Google+ shares or +1's.
 * See out post at stackoverflow.com/a/23088544/328272
 */
function get_gplus_count($url, $type = 'shares') {
  $curl = curl_init();

  // According to stackoverflow.com/a/7321638/328272 we should use certificates
  // to connect through SSL, but they also offer the following easier solution.
  curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

  if ($type == 'shares') {
    // Use the default developer key AIzaSyCKSbrvQasunBoV16zDH9R33D88CeLr9gQ, see
    // tomanthony.co.uk/blog/google_plus_one_button_seo_count_api.
    curl_setopt($curl, CURLOPT_URL, 'https://clients6.google.com/rpc?key=AIzaSyCKSbrvQasunBoV16zDH9R33D88CeLr9gQ');
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, '[{"method":"pos.plusones.get","id":"p","params":{"nolog":true,"id":"' . $url . '","source":"widget","userId":"@viewer","groupId":"@self"},"jsonrpc":"2.0","key":"p","apiVersion":"v1"}]');
    curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
  }
  elseif ($type == '+1s') {
    curl_setopt($curl, CURLOPT_URL, 'https://plusone.google.com/_/+1/fastbutton?url='.urlencode($url));
  }
  else {
    throw new Exception('No $type defined, possible values are "shares" and "+1s".');
  }

  $curl_result = curl_exec($curl);
  curl_close($curl);

  if ($type == 'shares') {
    $json = json_decode($curl_result, true);
    return intval($json[0]['result']['metadata']['globalCounts']['count']);
  }
  elseif ($type == '+1s') {
    libxml_use_internal_errors(true);
    $doc = new DOMDocument();
    $doc->loadHTML($curl_result);
    $counter=$doc->getElementById('aggregateCount');
    return $counter->nodeValue;
  }
}

// Get Google+ count.
$gplus_count = get_gplus_count($url, $gplus_type);

Answer 5

Google目前没有公共API来获取网址的+1计数。您可以提交功能请求here。您还可以使用@DerVo提到的reverse engineered方法。请记住，虽然该方法可以随时改变和破坏。

Answer 6

我已经汇编了这段代码，直接从社交按钮使用的iframe中读取数量。我没有在批量规模上测试它，所以也许你要减慢请求和/或更改用户代理:)。这是我的工作代码：

function get_plusone($url) 
{
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "https://plusone.google.com/_/+1/fastbutton?   
bsv&size=tall&hl=it&url=".urlencode($url));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
$html = curl_exec ($curl);
curl_close ($curl);
$doc = new DOMDocument();
$doc->loadHTML($html);
$counter=$doc->getElementById('aggregateCount');
return $counter->nodeValue;

}

用法如下：

echo get_plusones('http://stackoverflow.com/');

结果是：3166

我必须合并来自不同选项和网址的一些想法才能让它适合我：

function getPlusOnes($url) {
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, "https://plusone.google.com/_/+1/fastbutton?url=".urlencode($url));
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        $html = curl_exec ($curl);
        curl_close ($curl);
        $doc = new DOMDocument();
        $doc->loadHTML($html);
        $counter=$doc->getElementById('aggregateCount');
        return $counter->nodeValue;
    }

我所要做的只是更新网址，但我想为有兴趣的人发布一个完整的选项。

echo getPlusOnes('http://stackoverflow.com/')

感谢Cardy使用这种方法，然后我只需要得到一个适合我的网址...

我发布了一个PHP库，用于检索主要社交网络的计数。它目前支持谷歌，Facebook，Twitter和Pinterest。

使用的技术类似于此处描述的技术，库提供了一种缓存检索数据的机制。该库还有一些其他不错的功能：可通过Composer安装，经过全面测试，支持HHVM。
