新乡阿里云代理商：阿里云上传视频接口

阿里云上传视频可以使用阿里云的VOD服务。

1. 首先要在阿里云的控制台注册VOD服务并且获取到AccessKeyId和AccessKeySecret。
2. 在提供上传功能的应用中，使用阿里云VOD的SDK，将视频文件上传到阿里云的OSS中。上传成功后，会返回一个视频的OSS地址。
3. 将OSS地址传递给VOD服务，进行转码、封面提取、存储等操作。

以下是一个使用Java SDK进行视频上传的简单示例：

import com.aliyun.oss.OSSClient;
import com.aliyun.oss.model.PutObjectResult;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;
import com.aliyuncs.vod.model.v20170321.CreateUploadVideoRequest;
import com.aliyuncs.vod.model.v20170321.CreateUploadVideoResponse;
import com.aliyuncs.vod.model.v20170321.RefreshUploadVideoRequest;
import com.aliyuncs.vod.model.v20170321.RefreshUploadVideoResponse;

public class UploadVideoExample {

    private static String accessKeyId = "yourAccessKeyId";
    private static String accessKeySecret = "yourAccessKeySecret";
    private static String endpoint = "yourEndpoint";
    private static String bucketName = "yourBucketName";

    public static void main(String[] args) {

        // 初始化OSSClient
        OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret);

        // 上传视频到OSS
        String ossPath = "videos/test.mp4";
        PutObjectResult putObjectResult = ossClient.putObject(bucketName, ossPath, new java.io.File("test.mp4"));

        // 获取OSS中视频的url
        String ossUrl = ossClient.generatePresignedUrl(bucketName, ossPath, new Date(System.currentTimeMillis() + 3600 * 1000)).toString();

        // 初始化VodClient
        IClientProfile profile = DefaultProfile.getProfile("cn-shanghai", accessKeyId, accessKeySecret);
        DefaultAcsClient client = new DefaultAcsClient(profile);

        try {
            // 初始化CreateUploadVideoRequest
            CreateUploadVideoRequest createUploadVideoRequest = new CreateUploadVideoRequest();
            createUploadVideoRequest.setTitle("test-title");
            createUploadVideoRequest.setFileName("test.mp4");
            createUploadVideoRequest.setFileSize(putObjectResult.getMetadata().getContentLength());
            createUploadVideoRequest.setDescription("test-description");
            createUploadVideoRequest.setCoverURL("test-cover-url");
            // 其它属性根据需要设置

            // 发起CreateUploadVideoRequest请求并获取response
            CreateUploadVideoResponse createUploadVideoResponse = client.getAcsResponse(createUploadVideoRequest);

            // 获取VOD的上传地址和上传凭证
            String uploadAddress = createUploadVideoResponse.getUploadAddress();
            String uploadAuth = createUploadVideoResponse.getUploadAuth();

            // 上传视频到VOD
            HttpClient httpClient = new HttpClient();
            PostMethod postMethod = new PostMethod(uploadAddress);
            File file = new File("test.mp4");
            RequestEntity requestEntity = new InputStreamRequestEntity(new FileInputStream(file), file.length());
            postMethod.setRequestEntity(requestEntity);
            postMethod.setRequestHeader("Authorization", uploadAuth);
            httpClient.executeMethod(postMethod);

            // 刷新上传凭证
            String videoId = createUploadVideoResponse.getVideoId();
            RefreshUploadVideoRequest refreshUploadVideoRequest = new RefreshUploadVideoRequest();
            refreshUploadVideoRequest.setVideoId(videoId);
            RefreshUploadVideoResponse refreshUploadVideoResponse = client.getAcsResponse(refreshUploadVideoRequest);
            uploadAuth = refreshUploadVideoResponse.getUploadAuth();

            // 将视频的OSS地址和VOD的视频ID进行关联
            /** TODO: 根据实际场景调用对应API完成关联操作 **/
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

阿里云上传视频接口是一种通过API调用的方式将视频文件上传至阿里云服务器的接口。以下是具体步骤：

1. 首先需要获取阿里云的Access Key ID和Access Key Secret。
2. 根据阿里云提供的上传SDK进行开发，可参考官方文档：https://help.aliyun.com/document_detail/31883.html
3. 调用阿里云SDK中提供的上传接口，上传视频文件至阿里云服务器，接口中需要填写Access Key ID、Access Key Secret、Bucket名称、Object名称等参数。
4. 上传成功后，可以通过阿里云的CDN加速服务将视频文件加速分发到全球各地用户，实现最优的用户体验。
5. 上传后还可以通过阿里云的媒体处理服务对视频进行转码、截图等操作，实现视频的进一步优化。

以上就是阿里云上传视频接口的大致流程。如需更详细的接口参数、使用方法等，请参考阿里云官方文档或联系阿里云客服进行咨询。
