GP REST API<br />http://<catalog-url>/<serviceName>/GPServer<br />Task<br />http://<gpservice-url>/<taskName><br />Execute Task(Synchronous)<br />http://<task-url>/execute<br />执行同步任务, 发送请求后会一直处于等待状态, 直到任务执行完毕返回结果<br />Parameters<br />ParameterDetailsfDescription: The response format. The default response format is html. Values: html | json | kmz<gpParameter1>, <gpParameter2>, ...Description: The various input parameters accepted by the corresponding GP task. These parameters are listed in the parameters property of the JSON representation associated with the GP task resource.The valid values for the input parameters are dependent on the data type of the parameter. These values are discussed in more detail in submit job operation.<br />Example<br />http://a.com/ArcGIS/rest/services /ESRI_Currents_World/GPServer/MessageInABottle/execute?<br />Input_Point={quot;

The default response format is html.Values: html | json | image | kmzoutSRDescription: The spatial reference of the output geometries. The spatial reference can be specified as either a well-known ID or as a spatial reference json object. This parameter is applicable for result parameters that contain geometries. This parameter can be used to return the geometries in a spatial reference that is different from the spatial reference in which the outputs were initially created.returnTypeDescription: If the GP service is associated with a result map service, the default output for GPRasterDataLayer and GPFeatureSetLayer parameters is a map image. However, you can explicitly request the raw raster data by using returnType and setting its value to data.Values: data<br />Example<br />http://a.com/ArcGIS/rest/services/ /ESRI_CadastralData_Portland/GPServer/MailingList/jobs/ JE30155054C2C416EA3CF6C88A40B94FF/results/Output_Long?f=json<br />{<br /> quot;
