Shortest Path

**Table 1** **parameters** parameter description
Parameter	Mandatory	Description	Type	Value Range	Default Value
source	Yes	Source vertex ID of a path	String	-	-
target	Yes	Target vertex ID of a path	String	-	-
weight	No	Weight of an edge	String	Empty or character string Empty: The default weight and distance of edges are 1. Character string: The property of the corresponding edge is the weight. If the edge does not have a property, the weight is 1 by default. NOTE: The weight of an edge must be greater than 0.	-
directed	No	Whether to consider the edge direction	Boolean	The value can be true or false.	false
timeWindow	No	Time window used for time filtering	Json	For details, see Table 2. NOTE: timeWindow does not support the shortest path with weight. That is, parameters timeWindow and weight cannot be both specified.	-

**Table 2** **timeWindow** parameter description
Parameter	Mandatory	Description	Type	Value Range	Default Value
filterName	Yes	Name of the time property used for time filtering	String	Character string: The property on the corresponding vertex/edge is used as the time.	-
filterType	No	Filtering by vertex or edge	String	V: filtering by vertex E: filtering by edge BOTH: filtering by vertex and edge	BOTH
startTime	No	Start time	String	Date character string or timestamp	-
endTime	No	End time	String	Date character string or timestamp	-

**Table 3** **response_data** parameter description
Parameter	Type	Description
path	List	Shortest path. The format is as follows: [vertexId,...] where vertexId is of the string type.
source	String	Source vertex ID
target	String	Target vertex ID
