PHP WeChat development to obtain WeChat selected articles-PHP Tutorial-php.cn

This article mainly introduces in detail the simple implementation of PHP WeChat development to query the relevant information of WeChat selected articles. Interested friends can refer to it. I hope to be helpful.

Query some selected articles in WeChat with relatively large number of clicks.
Don’t forget to apply for apikey (you can get it by logging in to your Baidu account). Thefunctionto be completed is:

1. The user replies to "article", and the official account must return the number of the article category (For example, 9. Technology).

2. If the user replies wz9, 1, Tencent, the article with the keyword "Tencent" in the science and technology articles can be returned, and the first page will be displayed (wz9, 2, Tencent can return to the second page, The number of articles returned on each page can be customized, here I return 7 articles).

Detailed steps:

1. Reply to "article" and return the ids of all article categories. The following code is part of the responseMsg method

if(!empty($postStr)){ //解析post来的XML为一个对象$postObj $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $fromUsername = $postObj->FromUserName; //请求消息的用户 $toUsername = $postObj->ToUserName; //"我"的公众号id $keyword = trim($postObj->Content); //用户发送的消息内容 $time = time(); //时间戳 $msgtype = 'text'; //消息类型：文本 $textTpl = "   %s   ";

Copy after login

$which = mb_substr($keyword, 0, 2, 'UTF-8');

elseif($which == "文章"){ $ch = curl_init(); $url = 'http://apis.baidu.com/showapi_open_bus/weixin/weixin_article_type'; $header = array('apikey: 你自己的apikey'); // 添加apikey到header curl_setopt($ch, CURLOPT_HTTPHEADER , $header); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 执行HTTP请求 curl_setopt($ch , CURLOPT_URL , $url); $res = curl_exec($ch); $res = json_decode($res, true); //获取文章分类name和id foreach($res['showapi_res_body']['typeList'] as $v){ $article[] = $v['id'] . "、" . $v['name']; } sort($article, SORT_NUMERIC); foreach($article as $v){ $contentStr .= $v . "\n"; } $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgtype, $contentStr); echo $resultStr; exit(); }

Copy after login

2. At this time, the $resultStr of echo is the classification of all articles.Users can choose their favorite category to view articles based on the category ID. For example, by replying to wz19, 1, basketball, you can view articles about basketball classified as sports.
The specific calling interface and function implementation code are as follows:

elseif($which == "wz"){ list($art_id, $page_id, $keyname) = split('，', $keyword); $art_id = str_replace('wz', '', $art_id); $ch = curl_init(); $url = 'http://apis.baidu.com/showapi_open_bus/weixin/weixin_article_list?typeId=' . $art_id . '&page=' . $page_id . '&key=' . urlencode($keyname); $header = array('apikey: 你自己的apikey'); // 添加apikey到header curl_setopt($ch, CURLOPT_HTTPHEADER , $header); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 执行HTTP请求 curl_setopt($ch , CURLOPT_URL , $url); $res = curl_exec($ch); $res = json_decode($res, true); foreach($res['showapi_res_body']['pagebean']['contentlist'] as $k=>$v){ if($k <= 6){ $arts[] = $v; }else{ break; } } $items = ""; foreach($arts as $v){ $items .= " <![CDATA[" . $v['title'] . "]]>    "; } $textTpl = "   %s  7 " . $items . "   "; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time); echo $resultStr; exit(); }

Copy after login

Don’t forget to fill in$header = array('apikey: ');Your own apikey, otherwise the interface will refuse to return your request.
