Querying Vertex Data in Batches

Function

This API is used to query the vertex data (such as the labels and properties) in batches based on the vertex IDs.

URI

POST /ges/v1.0/{project_id}/graphs/{graph_name}/vertices/action?action_id=batch-query

Table 1 URI parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain the project ID, see Obtaining a Project ID.
graph_name	Yes	String	Graph name

Request Parameters

Table 2 Request body parameters
Parameter	Mandatory	Type	Description
vertices	Yes	String	Vertex IDs you use to query the vertices

Response Parameters

Table 3 Response body parameters
Parameter	Type	Description
errorMessage	String	System prompt. If execution succeeds, this parameter may be left blank. If execution fails, this parameter is used to display the error message.
errorCode	String	System prompt code. If execution succeeds, this parameter may be left blank. If execution fails, this parameter is used to display the error code.
data	Object	The data field is contained when the query is successful, and the data field contains the vertices query result.
result	String	Query results. If the request is successful, the value is success. If the request fails, the value is failed.

Example Request

Query nodes in batches by node ID. The vertex IDs to be queried are 27003509_Station Building and 39636392_Badaling Great Wall.

POST http://{SERVER_URL}/ges/v1.0/{project_id}/graphs/{graph_name}/vertices/action?action_id=batch-query  
{
  "vertices":
 ["27003509_Station Building",
 "39636392_Badaling Great Wall"]
}

Note

SERVER_URL: Address for accessing a graph. For details about its value, see Using Service Plane APIs.
