谷粒学院97——添加小节的视频上传功能

97.添加小节的视频上传功能

(1)引入依赖

已完成.

(2)配置appliaction.properties

# 服务端口号
server.port=8003

# 服务名
spring.application.name=service_vod

# 环境设置 dev test prod
spring.profiles.active=dev

# 最大上***个文件大小：默认1M
spring.servlet.multipart.max-file-size=1024MB
# 最大置总上传的数据大小 ：默认10M
spring.servlet.multipart.max-request-size=1024MB

# 阿里云 vod
aliyun.vod.file.keyid=xxx
aliyun.vod.file.keysecret=xxx

上面vod部分请读者自己配置。

(3)创建启动类

package com.wangzhou.vod;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;

// 该模块与数据库无交互，加入exclude参数避免报错
@SpringBootApplication(exclude = DataSourceAutoConfiguration.cla***包扫描规则，这样我们就能用到swager-ui等在com.wangzhou中存放的功能
@ComponentScan(basePackages = "com.wangzhou")
public class VodApplication {
    public static void main(String[] args) {
        SpringApplication.run(VodApplication.class ,args);
    }
}

(4)Controller

@RestController
@CrossOrigin
@RequestMapping("eduvod/video")
public class VodController {

    @Autowired
    private VodService vodService;

    @PostMapping("/uploadVideo")
    public R uploadVideo(MultipartFile file) {
        String videoId = vodService.uploadFile(file);
        return R.ok().data("videoId", videoId);
    }
}

(5)service

public interface VodService {

    String uploadFile(MultipartFile file);

}

 /**
     * 文件流上传接口
     *
     */
    @Override
    public String uploadFile(MultipartFile file) {
        try {
            String videoId;
            String accessKeyId = ConstantVodUtils.ACCESSKEY_ID;
            String accessKeySecret = ConstantVodUtils.ACCESSKEY_SECRET;
            String fileName = file.getOriginalFilename();
            String title = fileName.substring(0, fileName.lastIndexOf("."));

            UploadFileStreamRequest request = new UploadFileStreamRequest(accessKeyId, accessKeySecret, title, fileName);
            UploadVideoImpl uploader = new UploadVideoImpl();

            UploadFileStreamResponse response = uploader.uploadFileStream(request);
            /* 如果设置回调URL无效，不影响视频上传，可以返回VideoId同时会返回错误码。其他情况上传失败时，VideoId为空，此时需要根据返回错误码分析具体错误原因 */
            videoId = response.getVideoId();
            return videoId;
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }

(6)application.properties

# 服务端口号
server.port=8003

# 服务名
spring.application.name=service_vod

# 环境设置 dev test prod
spring.profiles.active=dev

# 最大上***个文件大小：默认1M
spring.servlet.multipart.max-file-size=1024MB
# 最大置总上传的数据大小 ：默认10M
spring.servlet.multipart.max-request-size=1024MB

# 阿里云 vod
aliyun.vod.file.keyid=LTAI5tFgGXoyhNYWPMHf3gNz
aliyun.vod.file.keysecret=C8acTTWjFrySJIarGvSfJVTQNce1vt

(7)ConstantVodUtils

@Component
public class ConstantVodUtils implements InitializingBean {
    @Value("${aliyun.vod.file.keyid}")
    private String keyId ;
    @Value("${aliyun.vod.file.keysecret}")
    private String keysecret;

    public static String ACCESSKEY_ID;
    public static String ACCESSKEY_SECRET;

    @Override
    public void afterPropertiesSet() throws Exception {
        ACCESSKEY_ID = keyId;
        ACCESSKEY_SECRET = keysecret;
    }
}
