前言:七牛雲是一個不錯的雲服務提供商,尤其是其對象存儲和cdn是有一定的免費額度,對於小衆開發者來說還是很划算的。爲了更好的用戶體驗和上傳速度,決定通過七牛雲存儲來上傳視頻文件。
前情圖示:
圖片來源:使用Element UI框架(基於vue2.0)的upload組件上傳圖片至七牛雲
一、找到你七牛雲存儲的區域的客戶端url
存儲區域 | 區域簡稱 | 上傳域名 |
華東 | z0 | http(s)://upload.qiniup.com |
華北 | z1 | http(s)://upload-z1.qiniup.com |
華南 | z2 | http(s)://upload-z2.qiniup.com |
文檔參考:七牛雲存儲直傳文件
二、 提供一個服務端接口:七牛上傳token接口
筆者使用php框架Laravel來提供接口服務,由於本身就已經使用了七牛擴展包overtrue/laravel-filesystem-qiniu。大同小異,隨便選擇一個七牛雲擴展也是可以完成此接口(基本是繼承七牛雲的SDK再造輪子)。
代碼:
// 第一步,引入七牛Auth類
use Qiniu\Auth;
// 第二步,實例話七牛Auth類
// config是Laravel框架自帶獲取配置參數的函數。其他框架或者語言請自行填寫
// config('filesystems.qiniu.access_key')是取配置文件中的access_key參數
// config('filesystems.qiniu.secret_key')是取配置文件中的secret_key參數
// config('filesystems.qiniu.bucket')是取配置文件中的bucket參數
$auth = new Auth(config('filesystems.qiniu.access_key'),env('filesystems.qiniu.secret_key'));
return response()->json([
'token' => $auth->uploadToken(config('filesystems.qiniu.bucket'))
]);
// 這裏建議如果使用cdn加速,以及其他一些參數可以在這個接口返回必須的字段。如返回
response()->json([
'action' => 'http://upload-z2.qiniup.com', // 七牛雲存儲客戶端直傳域名
'cdn' => 'https://cdn.xxxx.com', // cdn域名
'token' => $auth->uploadToken(config('filesystems.qiniu.bucket'))
]);
三、前端代碼模塊
我們應該自定義一個方法來實現。根據官方文檔,要覆蓋默認的行爲,要綁定http-request。這裏使用了el-progress來展示進度條,通過axios的onUploadProgress方法來獲取實時的進度,我們直接貼上代碼,具體實現的思想就在代碼裏了。
