Get Groups

This section covers operations to retrieve and query node groups. These operations are performed using the ESPRMUser instance.

备注

To get the user instance, use ESPRMAuth.getLoggedInUser method:

try {
  const authInstance = ESPRMBase.getAuthInstance();
  const userInstance = await authInstance.getLoggedInUser();
  
  if (userInstance) {
    // Use userInstance for group operations
  } else {
    console.log("No user is currently logged in");
  }
} catch (error) {
  console.error("Error getting logged in user:", error);
}

Get User Groups

To retrieve user groups, use the getGroups method. This method supports pagination to fetch groups in batches.

const requestParams = {
  resultCount: 10,
  withNodeList: true,
  withSubGroups: true
};

try {
  let allNodeGroups = [];
  let response = await userInstance.getGroups(requestParams);

  allNodeGroups = allNodeGroups.concat(response.groups);

  while (response.hasNext) {
    response = await response.fetchNext();
    allNodeGroups = allNodeGroups.concat(response.groups);
  }

  console.log("All node groups:", allNodeGroups);
} catch (error) {
  console.error("Error getting node groups:", error);
}

Get Group By ID

To retrieve a specific group by its ID, use the getGroupById method.

try {
  const group = await userInstance.getGroupById({
    groupId: "group_id_123"
  });
  console.log("Group details:", group);
} catch (error) {
  console.error("Error getting group by ID:", error);
}

Get Group By Name

To retrieve a specific group by its name, use the getGroupByName method.

try {
  const group = await userInstance.getGroupByName({
    groupName: "Living Room Devices"
  });
  console.log("Group details:", group);
} catch (error) {
  console.error("Error getting group by name:", error);
}
