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
- 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();
}
}
}
GO
- 代码示例
package main
import (
"fmt"
"github.com/aliyun/alibaba-cloud-sdk-go/sdk"
"github.com/aliyun/alibaba-cloud-sdk-go/sdk/requests"
)
func main() {
client, err := sdk.NewClientWithAccessKey("default", "<accessKeyId>", "<accessSecret>")
if err != nil {
panic(err)
}
request := requests.NewCommonRequest()
request.Method = "POST"
request.Scheme = "https" // https | http
request.Domain = "lc.<regionId>.aliyuncs.com"
request.Version = "2019-09-25"
// 注意下面的 [WorkflowId] 替换为刚才复制的 ID
request.PathPattern = "<Path>"
request.Headers["Content-Type"] = "application/json"
// 这里根据工作流需求设置参数
request.QueryParams["RegionId"] = "us-east-1"
// 这里根据工作流需求设置正文,注意是 JSON 字符串
body := ``
request.Content = []byte(body)
response, err := client.ProcessCommonRequest(request)
if err != nil {
panic(err)
}
fmt.Print(response.GetHttpContentString())
}
Python
- 代码示例
#!/usr/bin/env python
#coding=utf-8
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.request import CommonRequest
client = AcsClient('<accessKeyId>', '<accessSecret>', 'default')
request = CommonRequest()
request.set_accept_format('json')
request.set_method('POST')
request.set_protocol_type('https') # https | http
request.set_domain('lc.<regionId>.aliyuncs.com')
request.set_version('2019-09-25')
# 注意下面的 [WorkflowId] 替换为刚才复制的 ID
request.set_uri_pattern('<Path>')
# 这里根据工作流需求设置参数
request.add_query_param('RegionId', "us-east-1")
request.add_header('Content-Type', 'application/json')
# 这里根据工作流需求设置正文,注意是 JSON 字符串
body = ''''''
request.set_content(body.encode('utf-8'))
response = client.do_action_with_exception(request)
# python2: print(response)
print(str(response, encoding = 'utf-8'))
Ruby
# gem install aliyunsdkcore
require 'aliyunsdkcore'
client = ROAClient.new(
access_key_id: '<accessKeyId>',
access_key_secret: '<accessSecret>',
endpoint: 'https://lc.<regionId>.aliyuncs.com',
api_version: '2019-09-25'
)
response = client.request(
method: 'POST',
# 注意下面的 [WorkflowId] 替换为刚才复制的 ID
uri: '<Path>',
# 这里根据工作流需求设置参数
queries: {
"RegionId": "cn-hangzhou",
},
headers: {
"Content-Type": "application/json"
},
# 这里根据工作流需求设置正文,注意是 JSON 字符串
body: ``,
options: {}
)
print response
Node.js
- 安装依赖
npm install @alicloud/pop-core
- 代码示例
'use strict'
var ROAClient = require('@alicloud/pop-core').ROAClient;
var client = new ROAClient({
accessKeyId: '<your access key id>',
accessKeySecret: '<your access key secret>',
endpoint: 'https://lc.<regionId>.aliyuncs.com',
apiVersion: '2019-09-25',
});
async function test() {
try {
var res = await client.request(
'POST',
'<Path>',
{}, // 这里根据工作流需求设置参数
'<request body>', // 这里根据工作流需求设置正文,注意是 JSON 字符串
{
'content-type': 'application/json',
}
);
console.log('invoke workflow: ', res);
} catch (err) {
console.error(err);
}
}
test().then();
