使用 AccessKey 鉴权方式执行工作流，可以通过 SDK 调用执行，为您提供更安全的服务。

SDK逻辑编排目前提供了两种客户端调用方式，如果无需鉴权，可以直接调用 endpoint 执行工作流；如果选择的是 AccessKey 鉴权方式，需要配合 SDK 调用执行，可以通过以下步骤执行。

步骤

  1. 获取 Path

2. 通过 RAM 授权（使用子账号调用）

如果是使用子账号进行访问，请提前给子账号赋予权限，具体操作可参见 使用RAM授权。

3. 使用 SDK 调用

JAVA

  • 安装依赖

将 Maven 依赖项添加到 pom.xml 中

<dependency>
  <groupId>com.aliyun</groupId>
  <artifactId>aliyun-java-sdk-core</artifactId>
  <version>4.0.3</version>
</dependency>
  • 代码示例
import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.FormatType;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;

public class TestJavaSDK {
    public static void main(String[] args) {
        DefaultProfile profile = DefaultProfile.getProfile("default", "<accessKeyId>", "<accessSecret>");
        IAcsClient client = new DefaultAcsClient(profile);

        CommonRequest request = new CommonRequest();
        request.setProtocol(ProtocolType.HTTPS);
        request.setMethod(MethodType.POST);
        request.setDomain("lc.<regionId>.aliyuncs.com");
        request.setVersion("2019-09-25");
        
        request.setUriPattern("<Path>");
        // 这里根据工作流需求设置参数
        request.putQueryParameter("RegionId", "us-east-1");
        request.putHeadParameter("Content-Type", "application/json");
        // 这里根据工作流需求设置正文，注意是 JSON 字符串
        String requestBody = "";
        request.setHttpContent(requestBody.getBytes(), "utf-8", FormatType.JSON);
        try {
            CommonResponse response = client.getCommonResponse(request);
            System.out.println(response.getData());
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        }
    }
}
