Question

我发布了一个交通网络分析服务，想做连通性分析，但是返回的结果不对，一直显示的有连通。发布时我是把iserver-services.xml中的initFacilityAnalyest字段改为true，那么directionField字段应该设置成什么？smedgeid?

Answer 1

这个要根据您自己的数据来设置，就是在用桌面进行地图配置的时候数据中设置的相关的流向字段。您也可以参考我们自带的服务中的流向字段的值的设定

请问是在哪一步进行配置的呢？还有你们自带的服务的流向字段在哪看？

iserver自带的范例需要下载非deploy包，和iserver-services.xml文件同级目录会有一个iserver-services-sample.xml文件，其中就有相关的一些womeniserver自带的服务范例可以参考。这个是我从我们的范例的xml文件中找到的设定initFacilityAnalyest和directionField的范例，您可以参考一下
