既然自己開發，就需要獲取到資料，並給出編號；

這個也很簡單，根據api能很容易拿到資料，但是封面圖片的地址我在寫這個記錄的時候還是沒有拿到，不知道是我的方法不對，還是微信沒有這個介面，因為傳送圖文資訊需要一個圖片地址連結；因為我要個文章編號，所以我需要一條一條獲取，微信可以一次獲取20條資料。

1、獲取token；

2、獲取文章數量

3、獲取文章列表；

獲取token

wchat.php

/**
	* 獲取access_token
	*grant_type 獲取access_token填寫client_credential
	*appid 第三方使用者唯一憑證
	*secret 第三方使用者唯一憑證金鑰，即appsecret
	*/
	public function get_access_token()
	{
		//https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET
		$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".APPID."&secret=".SECRET;
		$response = file_get_contents($url);
		//返回資料格式:{"access_token":"ACCESS_TOKEN","expires_in":7200}
		//expires_in：憑證有效時間
		$res = json_decode($response, true);
		return $res['access_token'];
	}
 

獲取文章數量

wchat.php

{
  "voice_count":COUNT,
  "video_count":COUNT,
  "image_count":COUNT,
  "news_count":COUNT
}

/*
	*獲取文章數量
	*/
	public function get_article_count($access_token)
	{
		//https://api.weixin.qq.com/cgi-bin/material/get_materialcount?access_token=ACCESS_TOKEN
		$url = "https://api.weixin.qq.com/cgi-bin/material/get_materialcount?access_token=".$access_token;
		$response = file_get_contents($url);
		$res = json_decode($response, true);
		return $res;
	}
 

獲取文章列表

{
   "total_count": TOTAL_COUNT,
   "item_count": ITEM_COUNT,
   "item": [{
       "media_id": MEDIA_ID,
       "content": {
           "news_item": [{
               "title": TITLE,
               "thumb_media_id": THUMB_MEDIA_ID,
               "show_cover_pic": SHOW_COVER_PIC(0 / 1),
               "author": AUTHOR,
               "digest": DIGEST,
               "content": CONTENT,
               "url": URL,
               "content_source_url": CONTETN_SOURCE_URL
           },
           //多圖文訊息會在此處有多篇文章
           ]
        },
        "update_time": UPDATE_TIME
    },
    //可能有多個圖文訊息item結構
  ]
}

/*
