<networkDataName_uri>/edgeweight/{edgeID}/fromnode/{fromNodeID}/tonode/{toNodeID}/weightfield/{weightField}[.<format>]
The edgeWeight resource represents an edge weight. Performing a PUT request with proper parameters on the edgeWeight resource can update the weight of an edge.
Supported Methods:
Supported output formats: rjson, json, html, xml.
Below is an example of performing an HTTP request on a URI, with rjson as the output format. In the URI: supermapiserver is the name of the server; RoadNet@Changchun is the network data to be updated; and time is the weightField name set in the configuration file.
http://supermapiserver:8090/iserver/services/transportationanalyst-sample/rest/networkanalyst/RoadNet@Changchun/edgeweight/20/fromnode/26/tonode/109/weightfield/time.rjson
Updates the weight of an edge.
Proper parameters need to be included in the URI when performing a PUT request on the edgeWeight resource. The parameters that must be passed before "?" are as follows:
| Name | Type | Description |
| edgeID | int | The ID of the target edge. |
| fromNodeID | int | The ID of the starting node of the target edge. |
| toNodeID | int | The ID of the ending node of the target edge. |
| weightField | String | The name of the weight information (i.e., WeightFieldInfo) for the target edge. |
The parameter passed in the request entity body is a double type, specifying the new weight value.
After a PUT request is performed on the edgeWeight resource, the entity body of the response message contains a set of descriptions about whether the update is successful. The structure is as follows:
| Field | Type | Description |
| succeed | boolean | Whether the weight of the edge was successfully updated. |
| errorMsg | String | Details about the error if failure occurs. |
| code | int | Code of the error. |
Performing a PUT request on the following URI is to update the edge weights for the RoadNet@Network dataset:
http://supermapiserver:8090/iserver/services/transportationanalyst-sample/rest/networkanalyst/RoadNet@Changchun/edgeweight/20/fromnode/26/tonode/109/weightfield/time.rjson
The new weight specified in the request body is:
30.0
Given that the update is successful, the returned description of the operation result in rjson forma is as follows:
{
"succeed": true
}
