DataWorks:Best practices for calling API operations to develop, commit, and run tasks

You need to develop the ProjectService class. The class defines the ListProjects function that is used to call the ListProjects operation to query workspaces. After you call the operation, the workspaces that can be used for frontend development are returned.

package com.aliyun.dataworks.services;


import com.aliyuncs.dataworks_public.model.v20200518.ListProjectsRequest;
import com.aliyuncs.dataworks_public.model.v20200518.ListProjectsResponse;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


@Service
public class ProjectService {


    @Autowired
    private DataWorksOpenApiClient dataWorksOpenApiClient;


    /**
   	 * @param pageNumber
     * @param pageSize
     * @return
     */
    public ListProjectsResponse.PageResult listProjects(Integer pageNumber, Integer pageSize) {
        try {
            ListProjectsRequest listProjectsRequest = new ListProjectsRequest();
            listProjectsRequest.setPageNumber(pageNumber);
            listProjectsRequest.setPageSize(pageSize);
            ListProjectsResponse listProjectsResponse = dataWorksOpenApiClient.createClient().getAcsResponse(listProjectsRequest);
            System.out.println(listProjectsResponse.getRequestId());
            return listProjectsResponse.getPageResult();
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
            // The request ID.
            System.out.println(e.getRequestId());
            // The error code.
            System.out.println(e.getErrCode());
            // The error message.
            System.out.println(e.getErrMsg());
        }
        return null;
    }
}

You need to develop the BusinessService class. The class defines the following functions:

• The CreateBusiness function that can be used to call the CreateBusiness operation to create a workflow.

• The ListBusiness function that can be used to call the ListBusiness operation to query workflows.

The functions are used during frontend development to create a sample workflow and query workflows.

You need to develop the FileService class. The class defines the following functions that can be used to process files:

• The listFile function that can be used to call the ListFiles operation to query files.

• The createFile function that can be used to call the CreateFile operation to create files.

• The updateFile function that can be used to call the UpdateFile operation to update files.

• The deployFile function that can be used to call the DeployFile operation to deploy files.

• The runSmokeTest function that can be used to call the RunSmokeTest operation to perform smoke testing.

• The getInstanceLog function that can be used to call the GetInstanceLog operation to query the logs of an instance.

The functions can be used to create a file, query files, save a file, and commit and run a file.

You must follow the instructions provided in GitHub to prepare the environment. Make sure that the following dependencies are prepared: Java 8 or later, Maven, runtime environment, and pnpm. Then, perform initial installation.

pnpm install

You also need to modify information related to AccessKey pairs in the root path. Run the following command in the project root directory to run the sample code:

npm run example:ide

You can enter https://localhost:8080 in the address bar of a browser to verify the results.
