在百度进行搜索文章时，发现不少的博主文章都是有好几条的搜索结果，原来除了自己的官网博客外，还将文章同步到了新浪微博中，怪不得有怎么多条搜索的结果呢，这样做的最大好处就是让微博给自己的站点进行了曝光，尤其对于新站点来说，这样的功能就更不能缺少了，因为新站发布的文章百度都要过一段时间才能收录，因为没有百度蜘蛛过来抓取，但百度蜘蛛对于新浪微博可就不同了，新浪微博的权重很高，所以导致百度的抓取是最频繁的，所以一旦我们将文章发布到新浪微博上面，就会吸引来蜘蛛，然后会顺着新浪微博来到自己的博客中进行收录，哪么下面夏日博客就来教大家如何将 wordpress 的文章同步发送到新浪微博中，代码如下:

class sync_sina {

public $access_token = "";//access_token

public $default_image = "";//默认图片地址

public $host = "https://api.weibo.com/2/";

public static $boundary = '';

function __construct(){
/**
** 事件绑定
**/
add_action('publish_post', array($this, 'new_post_photo'));
}

function do_mu_post($url, $data) {
$ch = curl_init ();
$headers = array("Content-Type:multipart/form-data;boundary=". self::$boundary);
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, TRUE );
curl_setopt ( $ch, CURLOPT_POST, TRUE );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );
curl_setopt ( $ch, CURLOPT_URL, $url );
curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$ret = curl_exec ( $ch );
curl_close ( $ch );
return $ret;
}

function build_http_query_multi($params) {
if (!$params) return '';
uksort($params, 'strcmp');
$pairs = array();
self::$boundary = $boundary = uniqid('------------------');
$MPboundary = '--'.$boundary;
$endMPboundary = $MPboundary. '--';
$multipartbody = '';
foreach ($params as $parameter => $value) {
if( in_array($parameter, array('pic', 'image')) && $value{0} == '@' ) {
$url = ltrim( $value, '@' );
$content = file_get_contents( $url );
$array = explode( '?', basename( $url ) );
$filename = $array[0];
$multipartbody .= $MPboundary . "\r\n";
$multipartbody .= 'Content-Disposition: form-data; name="' . $parameter . '"; filename="' . $filename . '"'. "\r\n";
$multipartbody .= "Content-Type: image/unknown\r\n\r\n";
$multipartbody .= $content. "\r\n";
} else {
$multipartbody .= $MPboundary . "\r\n";
$multipartbody .= 'content-disposition: form-data; name="' . $parameter . "\"\r\n\r\n";
$multipartbody .= $value."\r\n";
}
}
$multipartbody .= $endMPboundary;
return $multipartbody;
}

function get_image($post_id){
if( has_post_thumbnail($post_id) ){
$timthumb_src = wp_get_attachment_image_src(get_post_thumbnail_id($post_id),'full');
$output = $timthumb_src[0];
} else {
$content = get_post_field('post_content', $post_id);
$defaltthubmnail = $this->default_image;
preg_match_all('/<img.*?(?: |\\t|\\r|\\n)?src=[\'"]?(.+?)[\'"]?(?:(?: |\\t|\\r|\\n)+.*?)?>/sim', $content, $strResult, PREG_PATTERN_ORDER);
$n = count($strResult[1]);
if($n > 0){
$output = $strResult[1][0];
} else {
$output = $defaltthubmnail;
}
}
return $output;
}

function new_post_photo($post) {
global $post;
if( $post->post_status != "publish" ){
$token = $this->access_token;
$url = $this->host ."statuses/upload.json";
$status = "夏日博客刚刚发布了新文章《".get_the_title()."》。".get_permalink();
$status .= mb_strimwidth(strip_tags(apply_filters('the_content', $post->post_content)), 0,180,"..."); //顺手加了个文章摘要，不喜欢就去掉啦
$pic_path = self::get_image($post->ID);
$params = array();
$params['access_token'] = $token;
$params['status'] = $status;
$params['pic'] = '@'.$pic_path;
$body = self::build_http_query_multi($params);
$result = self::do_mu_post($url,$body);

}
}
}
$HMT = new sync_sina();

将这段代码直接放到主题 functions.php 文件中即可，最后还要注意几点，使用本功能的时候需要先进行新浪微博官网的审核，另外需要服务器支持 file_get_contents函数以及 curl 组件，缺一不可额。
