INFO-调用中台open API（仅内部使用）

适用模块

离线开发

具体说明

open api调用mammut平台任务

使用示例

1、获取平台信息(需要平台管理员执行下列请求，email可以是普通具备执行任务的用户)
http://easydemo-workbench.163yun.com/api/user/apikey/set?email=用户账号 （需要在平台中的账户名，影响用户的权限等）
如：
http://easydemo-workbench.163yun.com/api/user/apikey/set?email=bigdata-test@taikangamc.com.cn

得到如下：
{"msg":"success","result":{"apikey":"7c419a6f-ec9e-49b3-92cc-434ec6e6aff5","masterkey":"2a9bc117-068e-4d99-b88d-d49d850d4a79","email":"bigdata-test@taikangamc.com.cn"},"code":200,"cost":9,"reqId":"dfa17f5c9f1a44b3972dd1836472a601"}

如下图所示：

2、获取token信息（工程见附件）
更改下列参数运行即可得到所需token （java代码如下）注：token  需要masterkey和url计算获得

package com.netease.hangkong;

import java.net.URLEncoder;
import java.nio.charset.StandardCharsets;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.Base64;

public class EncryptUtil {
    public static String md5(String msg) throws NoSuchAlgorithmException {
        MessageDigest md = MessageDigest.getInstance("MD5");
        md.update(msg.getBytes(StandardCharsets.UTF_8));
        byte[] digest = md.digest();
        return Base64.getEncoder().encodeToString(digest);
    }
    public static void main(String[] args) throws Exception {
        String master_key = "1d2cf5f0-b336-462c-acf1-e5202b9a95ce";
        String url = "/v1/openapi/etl/task/execute";
        String token = URLEncoder
                .encode(EncryptUtil.md5(master_key + url), "utf-8");
        System.out.println(token);

    }
}


public static void main(String[] args) throws NoSuchAlgorithmException, UnsupportedEncodingException {

        mammutOpenApi api = new mammutOpenApi();
        //api.test("/v1/openapi/etl/task/schedule");
        System.out.println(api.getToken("/v2/lineage/batch/table/task/writer"));  (换接口)

3、根据mammut.pdf接口信息执行请求
例如跑某个离线开发任务：请求字段参照pdf说明（pdf见附件）
以postman为调试工具

post请求：http://easydemo-workbench.163yun.com/v1/openapi/etl/task/execute
添加headers：
Content-Type=applications/json
body添加如下
{
    "apiKey": "5586b36a-b4a4-48a6-a96a-418757d1f772",
    "token": "T2ngUN7fOWb1GG%2BwcAzX7A%3D%3D",
    "product": "ebd_user",
    "clusterId": "easyops-cluster",
    "taskName": "ppack_transmit_kafka_service_v2",
    "flowName": "ppack_transmit_kafka_service_v2",
    "email": "admin.mammut@163.com",
    "disables": [],
    "doneNotify": false,
    "execSettings":{
        "concurrentOption": "skip",
        "failureAction": "finishPossible",
        "execQueue": "root.yq_ebd_user.default",
        "execpros": [
            {
                "key": "mapreduce.job.queuename",
                "value": "root.yq_ebd_user.default"
            },
            {
                "key": "yarnid",
                "value": "default"
            }
        ]
    }
}

返回
{
    "result": {
        "message": "Execution submitted successfully with exec id 23736",
        "execid": 23736
    },
    "code": 200
}
