Recently, a customer needed to implement such a function. After publishing article information on the WeChat public platform, they also needed to publish it again on the official website. This was equivalent to doing the same work twice. They wanted to implement it on the WeChat public platform. After the platform publishes the article, it can be published to the official website at the same time. Through research, the editor found that the official website of the WeChat public platform provides relevant information collection interfaces. The original address is as follows: https://developers.weixin.qq.com/doc /offiaccount/Asset_Management/Get_materials_list.html

The interface name is: Get permanent materials. In fact, when adding a new material article, click on the article material information saved after publishing, as shown below:

Only article materials that are being published can be collected if you click the publish button and save them to the publishing record--publishing, as shown below:

The editor will explain in detail below

##1 Get ACCESS_TOKEN

public function getAccessToken(){
    $info = Db::name('access_token')->order('inputtime desc')->find();
    if($info){
        $time = time();
        $long_time = $time - $info['updatetime'];
        if($long_time>=$info['expires_in']){
            $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$this->appid."&secret=".$this->secret;
            $res = $this->getJson($url);
            if(in_array('access_token',$this->DbSy->GetArrElement($res))){
                $insert['access_token'] = $res['access_token'];
                $insert['expires_in'] = $res['expires_in'];
                $insert['updatetime'] = time();
                $up_info = Db::name('access_token')->where('id',$info['id'])->update($insert);
                if(!$up_info){
                    return json(['code'=>103,'msg'=>'AccessToken更新失敗']);
                }
                $AccessToken = $res['access_token'];
            }else{
                return json(['code'=>100,'msg'=>'AccessToken獲取失敗']);
            }
        }else{
            $AccessToken = $info['access_token'];
        }
    }else{
        $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$this->appid."&secret=".$this->secret;
        $res = $this->getJson($url);
        if(in_array('access_token',$this->DbSy->GetArrElement($res))){
            $insert['access_token'] = $res['access_token'];
            $insert['expires_in'] = $res['expires_in'];
            $insert['updatetime'] = time();
            $insert['inputtime'] = time();
            $up_info = Db::name('access_token')->where('id',$info['id'])->insertGetId($insert);
            if($up_info){
                $AccessToken = $res['access_token'];
            }else{
                return json(['code'=>101,'msg'=>'AccessToken插入失敗']);
            }

        }else{
            return json(['code'=>100,'msg'=>'AccessToken獲取失敗']);
        }
    }
    return $AccessToken;
}

Note:

Before production, you need to add the data table: access_token in the database, which is used to store the obtained access_token value, because the validity period of each obtained access_token value is 7200s, so as to avoid repeated acquisition of the access_token value.

2 Obtain the material list

After obtaining the access_token value, you can obtain the material list through the access_token value:

public function getArticleList($offset,$type='news',$length=20){
    $data = array(
        'type'=>$type,
        'offset'=>$offset,
        'count'=>$length
    );
    $json_data = json_encode($data);
    $AccessToken = $this->getAccessToken();
    $url = "https://api.weixin.qq.com/cgi-bin/material/batchget_material?access_token=".$AccessToken;
    $res = $this->getJsonData($url,$json_data);
    return $res;
    //dump($res);
}

Among them:

(1) type, the type of material, image, video, voice, news

(2) offset, the offset from all materials The position starts to return, 0 means returning from the first material

(3) count, the number of returned materials, the value is between 1 and 20
