How does wordpress connect to Weibo to synchronize articles?

WordPress对接微博使WordPress文章同步到微博

WordPress文章发布后无插件自动同步到新浪微博详细步骤:

1、申请新浪微博APPKEY

申请地址:http://open.weibo.com/

我们需要有自己的新浪微博账户,然后登陆上面的地址,申请APPKEY。

(1)申请网站接入

(3)网站接入完成后,在我的应用下面会看到自己刚接入的网站,这个时候我们需要记下如下图位置处的App Key

2、修改wordpress代码

在当前使用的主题根目录下的functions.php中加入如下代码:

function post_to_sina_weibo($post_ID) {

   /* 此处修改为通过文章自定义栏目来判断是否同步 */
   if(get_post_meta($post_ID,'weibo_sync',true) == 1) return;

   $get_post_info = get_post($post_ID);
   $get_post_centent = get_post($post_ID)->post_content;
   $get_post_title = get_post($post_ID)->post_title;
   if ($get_post_info->post_status == 'publish' && $_POST['original_post_status'] != 'publish') {
       $appkey='上个步骤获取的App key';  
       $username='用户名';
       $userpassword='密码';
       $request = new WP_Http;
       $keywords = ""; 

       /* 获取文章标签关键词 */
       $tags = wp_get_post_tags($post_ID);
       foreach ($tags as $tag ) {
          $keywords = $keywords.'#'.$tag->name."#";
       }

      /* 修改了下风格,并添加文章关键词作为微博话题,提高与其他相关微博的关联率 */
     $string1 = '【文章发布】' . strip_tags( $get_post_title ).':';
     $string2 = $keywords.' 查看全文:'.get_permalink($post_ID);

     /* 微博字数控制,避免超标同步失败 */
     $wb_num = (138 - WeiboLength($string1.$string2))*2;
     $status = $string1.mb_strimwidth(strip_tags( apply_filters('the_content', $get_post_centent)),0, $wb_num,'...').$string2;
     
		if ( has_post_thumbnail()) {   
			$timthumb_src = wp_get_attachment_image_src( get_post_thumbnail_id($post_ID), 'full' ); 
			$url = $timthumb_src[0]; 
		} else {
			preg_match_all(&#39;/<img .*?(?: |\\t|\\r|\\n)?src=[\&#39;"]?(.+?)[\&#39;"]?(?:(?: |\\t|\\r|\\n)+.*?)? alt="How does wordpress connect to Weibo to synchronize articles?" >/sim&#39;, $get_post_centent,	$strResult, PREG_PATTERN_ORDER);  //正则获取文章中第一张图片
			$n = count($strResult[1]);  
			if($n > 0){
				$url=$strResult[1][0];  
			}
		}
	   /* 判断是否存在图片,定义不同的接口 */
       if(!empty($url)){
           $api_url = &#39;https://api.weibo.com/2/statuses/upload_url_text.json&#39;; /* 新的API接口地址 */
           $body = array(&#39;status&#39; => $status,&#39;source&#39; => $appkey,&#39;url&#39; => $url);
       } else {
           $api_url = &#39;https://api.weibo.com/2/statuses/update.json&#39;;
           $body = array(&#39;status&#39; => $status,&#39;source&#39; => $appkey);
       }
       $headers = array(&#39;Authorization&#39; => &#39;Basic &#39; . base64_encode("$username:$userpassword"));
       $result = $request->post($api_url, array(&#39;body&#39; => $body,&#39;headers&#39; => $headers));

       /* 若同步成功,则给新增自定义栏目weibo_sync,避免以后更新文章重复同步 */
       add_post_meta($post_ID, &#39;weibo_sync&#39;, 1, true);
    }
}
add_action(&#39;publish_post&#39;, &#39;post_to_sina_weibo&#39;, 0);

/*
//获取微博字符长度函数 
*/
function WeiboLength($str)
{
    $arr = arr_split_zh($str);   //先将字符串分割到数组中
    foreach ($arr as $v){
        $temp = ord($v);        //转换为ASCII码
        if ($temp > 0 && $temp < 127) {
            $len = $len+0.5;
        }else{
            $len ++;
        }
    }
    return ceil($len);        //加一取整
}
/*
//拆分字符串函数,只支持 gb2312编码  
//参考:http://u-czh.iteye.com/blog/1565858
*/
function arr_split_zh($tempaddtext){
    $tempaddtext = iconv("UTF-8", "GBK//IGNORE", $tempaddtext);
    $cind = 0;
    $arr_cont=array();
    for($i=0;$i<strlen($tempaddtext);$i++)
    {
        if(strlen(substr($tempaddtext,$cind,1)) > 0){
            if(ord(substr($tempaddtext,$cind,1)) < 0xA1 ){ //如果为英文则取1个字节
                array_push($arr_cont,substr($tempaddtext,$cind,1));
                $cind++;
            }else{
                array_push($arr_cont,substr($tempaddtext,$cind,2));
                $cind+=2;
            }
        }
    }
    foreach ($arr_cont as &$row)
    {
        $row=iconv("gb2312","UTF-8",$row);
    }
    return $arr_cont;
}

至此我们只要修改上述代码中的三处,其中APP KEY直接修改成我们自己的APP KEY,然后输入自己的微博账户和密码。
