我是卡蒙达的初学者。我想完成一项任务。因此，我首先调用一个实例：

http://localhost:8080/engine-rest/process-definition/key/approve-loan/submit-form

通过邮递员和邮寄请求提供下列数据：

{
  "variables": {
    "customerId": {"value":"Niall","type":"String"},
    "amount":{"value":"100","type":"String"}
  }
}

和Content-Type : application/json

我有以下输出：

{
  "links": [
    {
      "method": "GET",
      "href": "http://localhost:8080/engine-rest/process-instance/3f219a2a-138e-11e7-b49e-104a7ddf1366",
      "rel": "self"
    }
  ],
  "id": "3f219a2a-138e-11e7-b49e-104a7ddf1366",
  "definitionId": "approve-loan:2:8cd1ab3c-1303-11e7-b49e-104a7ddf1366",
  "businessKey": null,
  "caseInstanceId": null,
  "ended": false,
  "suspended": false,
  "tenantId": null
}

我查看了camunda博客，发现我可以通过调用(POST request)：http://localhost:8080/engine-rest/task/3f219a2a-138e-11e7-b49e-104a7ddf1366/complete来完成任务实例，因为我有以下响应，所以这个问题无法工作：

{
  "type": "RestException",
  "message": "Cannot complete task 3f219a2a-138e-11e7-b49e-104a7ddf1366: Cannot find task with id 3f219a2a-138e-11e7-b49e-104a7ddf1366: task is null"
}

而tomcat控制台中的这个异常：

        ... 37 more

我已经调用http://localhost:8080/engine-rest/task/?processInstanceId=3f219a2a-138e-11e7-b49e-104a7ddf1366来获取属性，响应是

[
  {
    "id": "3f220f63-138e-11e7-b49e-104a7ddf1366",
    "name": "Approve Loan",
    "assignee": "john",
    "created": "2017-03-28T10:12:12",
    "due": null,
    "followUp": null,
    "delegationState": null,
    "description": null,
    "executionId": "3f219a2a-138e-11e7-b49e-104a7ddf1366",
    "owner": null,
    "parentTaskId": null,
    "priority": 50,
    "processDefinitionId": "approve-loan:2:8cd1ab3c-1303-11e7-b49e-104a7ddf1366",
    "processInstanceId": "3f219a2a-138e-11e7-b49e-104a7ddf1366",
    "taskDefinitionKey": "UserTask_11fud4o",
    "caseExecutionId": null,
    "caseInstanceId": null,
    "caseDefinitionId": null,
    "suspended": false,
    "formKey": "embedded:app:forms/approve-loan.html",
    "tenantId": null
  }
]

我使用了id和executionId，但仍然会出错。

有什么帮助吗？

感谢@Zelldon :工作网址是http://localhost:8080/engine-rest/task/3f220f63-138e-11e7-b49e-104a7ddf1366/complete

我只需要从http://localhost:8080/engine-rest/task/?processInstanceId=3f219a2a-138e-11e7-b49e-104a7ddf1366呼叫后得到的响应中获取id

请把它标为已解决，因为我不能。
