Android-调用优酷SDK上传视频

 

最近在研究用优酷的SDK来进行视频上传的功能，由于优酷的SDK只是提供了一个上传的sample code，没有涉及到授权的过程，对于新手来说，可能非常棘手，现在分享一下我的思路：

 

程序实现前我们先要到优酷开放平台下载SDK（下载地址：http://open.youku.com/down）

根据优酷SDK的说明，上传过程主要分为以下7个步骤：

1. 新建Android项目，引入YoukuUploadSDK-android jar包

2. 在MainActivity.Java文件添加代码如sample.java所示，添加相关参数

3. 文件夹layout下activity_main.xml添加控件

4. 生成代码（xml文件代码）

5. 连接android手机运行android项目生成apk（切记开启开发者选项usb调试等）

6. 授权过程(获取access_token)

7. 点击upload上传

 

其他的几步按照文档来做，应该不会有问题，下面重点说说步骤6的授权过程。

我们只能采用通用授权的方式(合作级别的授权方式需要收费)，关于授权机制，请参考http://open.youku.com/docs/OAuth2.html。

大概思路就是，通过一个WebView来显示授权页面获取授权码（code），我们需要使用http方法get的方式来获取授权码(code)，所需的参数请参考http://open.youku.com/docs/OAuth2.html?id=101，然后通过使用授权码（code）来交换令牌即所谓的access_token，最后通过access_token来获取上传的权限。

代码如下看代码：

            return access_token;
        }
        @Override
        protected void onDestroy() {
        // TODO Auto-generated method stub
            if(webview != null){
                webview = null;
            }
        super.onDestroy();
        }
     
}

通过上述方法，我们可以很简单地获取优酷上传视频所需要的access_token，获取了access_token以后，我们就可以将access_token设置到params的参数中，这样我们就能实现上传视频到优酷了！如下：
