上傳臨時素材文件

根據開發文檔,可以看出,需要三個參數access_token、type、media,
access_token和type容易解決,media的話就要寫一個表單上傳過來
表單如下:
<form action="<{$upload_url}>" name="file" method="POST" enctype="multipart/form-data">
<input type="file" name="image_file" value="選擇">
<input type="submit" value="上傳">
- </form>
表單提交后,即可開始上傳
private function upload_image($image_file) {
$access_token = $this->get_access_token($this->corpid, $this->corpsecret);
$type = 'image';
//這里是個坑,臨時文件不能上傳,需要保存到某個路徑下再上傳
$upload_dir = SYSTEM_DATA . "upload/test/";
!is_dir($upload_dir) and mkdir($upload_dir, 0755, true);
$file_path = $upload_dir . $image_file["name"];
//這里用move_uploaded_file也可以
copy($image_file["tmp_name"], $file_path);
$post_data = array(
//這里是個坑,要在前面加@(@是禁止將字符串中的斜杠解釋為轉義字符)
"media" => "@" . $file_path,
);
$url = 'https://qyapi.weixin.qq.com/cgi-bin/media/upload?access_token=' . $access_token . '&type=' . $type;
$array_result = json_decode($this->https_request($url, $post_data), TRUE);
return $array_result['media_id'];
}
獲取臨時素材文件

根據開發文檔,可以看出,需要兩個參數access_token和media_id,media_id就是上面上傳時返回的media_id
private function download_image($media_id) {
$access_token = $this->get_access_token($this->corpid, $this->corpsecret);
$url = 'https://qyapi.weixin.qq.com/cgi-bin/media/get?access_token=' . $access_token . '&media_id=' . $media_id;
$a = file_get_contents($url);
//以讀寫方式打開一個文件,若沒有,則自動創建
$download_dir = SYSTEM_DATA . "download/test";
!is_dir($download_dir) and mkdir($download_dir, 0755, true);
$resource = fopen($download_dir."/$media_id.jpg" , 'w+');
//將圖片內容寫入上述新建的文件
fwrite($resource, $a);
//關閉資源
fclose($resource);
}
