dolphinscheduler api 创建工作流

以下是使用DolphinScheduler API创建工作流的步骤：

1.登录DolphinScheduler并获取到登录凭证token。

2.创建工作流定义，包括工作流名称、描述、版本号、租户ID等信息。请求示例：

POST /dolphinscheduler/projects/{projectName}/processes HTTP/1.1
Host: dolphinscheduler-server-host:port
Content-Type: application/json
Authorization: Bearer token

{
    "processDefinition": {
        "name": "test_workflow",
        "description": "test_workflow_description",
        "locations": [
            {
                "name": "shell"
            }
        ],
        "tasks": [
            {
                "name": "task_1",
                "description": "task_1_description",
                "type": "SHELL",
                "params": {
                    "rawScript": "echo 'hello world'"
                },
                "preTasks": [],
                "postTasks": []
            },
            {
                "name": "task_2",
                "description": "task_2_description",
                "type": "SHELL",
                "params": {
                    "rawScript": "echo 'hello world'"
                },
                "preTasks": [
                    {
                        "name": "task_1",
                        "type": "SHELL"
                    }
                ],
                "postTasks": []
            },
            {
                "name": "task_3",
                "description": "task_3_description",
                "type": "SHELL",
                "params": {
                    "rawScript": "echo 'hello world'"
                },
                "preTasks": [
                    {
                        "name": "task_2",
                        "type": "SHELL"
                    }
                ],
                "postTasks": []
            }
        ],
        "timeout": {
            "strategy": "FAILED",
            "interval": 1,
            "enable": false
        },
        "tenantId": 1,
        "receivers": "",
        "receiversCc": "",
        "warningType": "NONE",
        "processInstancePriority": "MEDIUM",
        "workerGroupId": -1,
        "timeoutFlag": false,
        "taskRetryTimes": 0,
        "retryInterval": 1,
        "runFlag": "NORMAL",
        "dependence": {
            "relation": "AND",
            "dependTaskList": []
        },
        "globalParams": []
    },
    "releaseState": "ONLINE"
}

3.创建工作流实例，即启动工作流。请求示例：

POST /dolphinscheduler/projects/{projectName}/processes/{processDefinitionId}/start-time HTTP/1.1
Host: dolphinscheduler-server-host:port
Content-Type: application/json
Authorization: Bearer token

{
    "scheduleTime": "2022-01-01 00:00:00",
    "failureStrategy": "END",
    "startNodeList": [
        {
            "name": "task_1",
            "type": "SHELL"
        }
    ],
    "taskDependType": "ALL_SUCCESS",
    "timeout": {
        "strategy": "FAILED",
        "interval": 1,
        "enable": false
    },
    "workerGroupId": -1,
    "processInstancePriority": "MEDIUM",
    "warningType": "NONE",
    "startParams": "",
    "runMode": "NORMAL",
    "environmentParams": "",
    "globalParams": []
}

4.查询工作流实例状态。请求示例：

GET /dolphinscheduler/projects/{projectName}/processes/{processInstanceId}/status HTTP/1.1
Host: dolphinscheduler-server-host:port
Content-Type: application/json
Authorization: Bearer token
