一，賬號需要有oss和mps的許可權

java sdk通過 accessKeyId和accessKeySecret可以呼叫介面。

但是你這個授權使用者，還需要oss和mps兩個許可權

二，建立一個管道

這個很方便，直接在下面建立

https://mps.console.aliyun.com/pipeline/list

三，程式碼

public ApiResult<FileVO> test2() {
        String accessKeyId = "xxx";
        String accessKeySecret = "xxx";
        String mpsRegionId 
 
= "cn-hangzhou";
        String pipelineId = "xxx";
//模板配置的是轉碼方案，你也可以直接通過程式碼實現例如：container.put("Format", "mp4");
        String templateId = "xxx";
        String ossLocation = "oss-cn-hangzhou";
//例如: myBucket-qa
        String ossBucket = "xxx";
//資源路徑：具體的資料夾+檔案（沒有資料夾的話，自行去掉）
        String ossInputObject = "advertisement/00f89c4c623948d3b8a068d8b9de089c.mp4";
 
//轉碼後的資源路徑
        String ossOutputObject = "advertisement/output.mp4";
        // 建立DefaultAcsClient例項並初始化
        DefaultProfile profile = DefaultProfile.getProfile(
                mpsRegionId,      // 地域ID
                accessKeyId,      // RAM賬號的AccessKey ID
                accessKeySecret); // RAM賬號Access Key Secret
 

        IAcsClient client = new DefaultAcsClient(profile);
        // 建立API請求並設定引數
        SubmitJobsRequest request = new SubmitJobsRequest();
        // Input
        JSONObject input = new JSONObject();
        input.put("Location", ossLocation);
        input.put("Bucket", ossBucket);
        try {
            input.put("Object", URLEncoder.encode(ossInputObject, "utf-8"));
        } catch (UnsupportedEncodingException e) {
            throw new RuntimeException("input URL encode failed");
        }
        request.setInput(input.toJSONString());
        // Output
        String outputOSSObject;
        try {
            outputOSSObject = URLEncoder.encode(ossOutputObject, "utf-8");
        } catch (UnsupportedEncodingException e) {
            throw new RuntimeException("output URL encode failed");
        }
        JSONObject output = new JSONObject();
        output.put("OutputObject", outputOSSObject);
        // Ouput->Container
        JSONObject container = new JSONObject();
        container.put("Format", "mp4");
        output.put("Container", container.toJSONString());
        // Ouput->TemplateId
//        output.put("TemplateId", templateId);
        JSONArray outputs = new JSONArray();
        outputs.add(output);
        request.setOutputs(outputs.toJSONString());
        request.setOutputBucket(ossBucket);
        request.setOutputLocation(ossLocation);
        // PipelineId
        request.setPipelineId(pipelineId);
        // 發起請求並處理應答或異常
        SubmitJobsResponse response;
        try {
            response = client.getAcsResponse(request);
            System.out.println("RequestId is:" + response.getRequestId());
            if (response.getJobResultList().get(0).getSuccess()) {
                System.out.println("JobId is:" + response.getJobResultList().get(0).getJob().getJobId());
            } else {
                System.out.println("SubmitJobs Failed code:" + response.getJobResultList().get(0).getCode() +
                        " message:" + response.getJobResultList().get(0).getMessage());
            }
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        }
        return null;
    }

四，結果：
