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
(2)按照下图流程进行操作:
(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('/<img .*?(?: |\\t|\\r|\\n)?src=[\'"]?(.+?)[\'"]?(?:(?: |\\t|\\r|\\n)+.*?)? alt="How does wordpress connect to Weibo to synchronize articles?" >/sim', $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 = 'https://api.weibo.com/2/statuses/upload_url_text.json'; /* 新的API接口地址 */ $body = array('status' => $status,'source' => $appkey,'url' => $url); } else { $api_url = 'https://api.weibo.com/2/statuses/update.json'; $body = array('status' => $status,'source' => $appkey); } $headers = array('Authorization' => 'Basic ' . base64_encode("$username:$userpassword")); $result = $request->post($api_url, array('body' => $body,'headers' => $headers)); /* 若同步成功,则给新增自定义栏目weibo_sync,避免以后更新文章重复同步 */ add_post_meta($post_ID, 'weibo_sync', 1, true); } } add_action('publish_post', 'post_to_sina_weibo', 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。
