![]() To verify if the installation has successfully setup the required REST environment, open IIS Manager -> Sites. IIS (Internet Information Services) 7.0 or higher is installed and configured (refer to the Configuring IIS for REST API section in NosDB Administrator's Guide).Generally, the installation setup of NosDB automatically creates a new application pool and deploys REST API as an application in the default website on your systems provided that the following conditions are duly met: Configuring and Deploying the NosDB REST APIīefore delving into the world of REST-based programming, you need to ensure that your environment is suitably configured. The goal of this article is to present an introductory walk-through regarding the use of REST with NosDB. In previous articles, the NosDB client API and server side APIs were described in detail. This way, languages like JavaScript, Python, and Ruby-on-Rails can access NosDB without having to implement any communication protocols. Since we want our databases to be easily accessible via applications (like web or mobile) and not be restricted by platform constraints, NosDB provides a ready-to-publish-in-production REST API in addition to the existing NosDB clients (.NET and JAVA). It depends on resources which are uniquely represented by URLs and normally supports the four basic HTTP verbs: GET, POST, PUT and DELETE. REpresentational State Transfer (REST) uses HTTP as the medium to communicate with a data source and returns results in the form of JSON. Because of this, numerous clients, irrespective of their environment, are able to update and retrieve user data effectively. With the emergence of web services, user applications have been able to communicate with remote data sources without having to rely on discrete platforms. ![]() JSON structures: geometryType=&geometry=&geometryType=esriGeometryPoint&inSR=4326&spatialRel=esriSpatialRelIntersects&outFields=*&returnGeometry=false&returnIdsOnly=true&f=htmlĮxample 3: Query distinct sensors and products in an image service.Introduction to REST API in NoSQL Database - NosDB.In addition to the JSON structures, for envelopes and points, you can specify the geometry with a comma-separated syntax. The structure of the geometry is the same as the structure of the JSON geometry objects returned by the ArcGIS REST API. The geometry to apply as the spatial filter. Time extent (For time extents, one of or could be 'null').Įxample: time=1199145600000, 1230768000000 ( 00:00:00 GMT to 00:00:00 GMT)Ī null value specified for startTime or endTime will represent infinity for start or end time, respectively. You can provide arguments to the query operation as query parameters defined in the parameters table below.Įxample: time=1199145600000 ( 00:00:00 GMT) When the exceededTransferLimit property is false or missing, it indicates that you have reached the end of the query results.Īt 10.4, the query operation supports geometryPrecision, maxAllowableOffset, and returnTrueCurves.Īt 10.3.1, the query operation supports resultOffset and resultRecordCount.Īt 10.3, the query operation supports multidimensionalDefinition.Īt 10.2.1, the query operation supports outStatistics, groupByFieldsForStatistics, orderByFields, and returnDistinctValues. When exceededTransferLimit is true, it indicates there are more query results, and you can continue to page through the results. This property is typically used when paging through a query result with the optional resultOffset and resultRecordCount parameters, and it will also be affected by the maxRecordCount image service property. Clients can exploit this to get all the query-conforming object IDs by specifying returnIdsOnly=true and subsequently requesting feature sets for subsets of object IDs.Īt 10.8.1, the query operation supports rasterQuery if the image service uses ArcObjects11 or ArcObjectsRasterRendering as the service provider.Īt 10.7, the exceededTransferLimit property is included in the JSON response if it hasn’t reached the end of the query results. While there is a limit ( maxRecordCount) to the number of features included in the feature set response, there is no limit to the number of object IDs returned in the ID array response. The result of this operation is a set of features or an array of raster IDs (if returnIdsOnly is set to true), a count (if returnCountOnly is set to true), or a set of field statistics (if outStatistics is used). It queries by applying the filter specified by the user. The query operation is performed on an image service resource. As of 10.5, you must license your ArcGIS Server as an ArcGIS Image Server to use this resource. ![]()
