Adding Edges in Batches

Function

This API is used to add edges in batches.

URI

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

**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

Parameter	Mandatory	Type	Description
edges	Yes	Object	Edge array to be added
parallelEdge	No	Object	How to process repetitive edges
action	No	String	Processing mode. The value can be override or ignore. If the value is override, the previous repetitive edges are overwritten. If the value is ignore and an edge already exists, the previous edge will not be overwritten. If no edge exists, the system adds an edge.
ignoreLabel	No	Boolean	Whether to ignore labels on repetitive edges. The value can only be false. false: Edges with the same source vertex, target vertex, and label are duplicate edges.
createNotExists	No	Boolean	Whether to add source or target vertices that do not exist in the edges parameter before adding edges. The value can only be false. false: Edges can be added regardless of whether the source or target vertex exists.

**Table 2** edges parameter description
Parameter	Mandatory	Type	Description
source	Yes	String	Source vertex of an edge
target	Yes	String	Target vertex of an edge
label	Yes	String	Edge label
properties	No	Object	Value of each property

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. If execution succeeds, this parameter may be left blank. If execution fails, this parameter is used to display the error code.
result	String	Request result. If the request is successful, the value is success. If the request fails, the value is failed.

Example Request

Add edges in batches. The source vertex is 46, the target vertices are 39 and 38, and the edge label is rate.

POST http://{SERVER_URL}/ges/v1.0/{project_id}/graphs/{graph_name}/edges/action?action_id=batch-add

                ]

        }
    ],
    "parallelEdge": {
        "action": "override",
        "ignoreLabel": false
    },
    "createNotExists": false
}

SERVER_URL: Address for accessing a graph. For details about its value, see Using Service Plane APIs.
In the example, if vertices 666 and 777 are not in the original graph, create vertices 666 and 777, retain the default value of each label, and add an edge.
