我是JBPM新手，最近我开始使用jBPM Workbench展示Docker镜像，更具体地说是招聘过程。一切工作正常在控制台上，但是当我试图使用JBPM rest API来控制过程时，我得到了一个PermissionDeniedException。在JBPM返回执行索赔休息调用PermissionDeniedException
当我想要使用[POST] /task/{taskId}/claim声明任务时发生错误。我有以下异常：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<exception>
<status>FAILURE</status>
<url>http://localhost:8080/jbpm-console/rest/task/1/claim</url>

我不明白的东西，我想声明该任务使用用户katy，但错误显示用户admin没有权限！ 
感谢您的回答！我完全同意你和我'米不试图与管理员用户执行任务，而是我'米使用一个从合格组（凯蒂在我的情况！检查图像）！我不知道'为什么它考虑来自'admin'的呼叫 – Aboullaite
看起来像你使用google-chrome中的POSTMAN工具发送请求，并且在浏览器中，你使用admin用户登录到jbpm-console。如果我的理解是正确的，那么先从浏览器注销管理员用户，然后尝试执行REST API。 – Abhijit
哦不，你说的对！尝试了旧的简单卷曲命令，它的作用就像一个魅力。邮差显然有些问题。谢谢 – Aboullaite
