The RESO Commander offers the following command line utilities:
- Getting Metadata
- Validating XML Metadata
- Requesting and Saving Results
- Running RESOScript Files
- Displaying RESOScript Testing Queries
In order to run the RESO Commander locally, you must have the Java Runtime Environment (JRE) version 8, 10, or 12 installed.
You may also use Docker if you prefer.
Your operating system probably already has a Java Runtime Environment (JRE) installed. This is all you need to run the Commander as a Web API Client.
To check your version of Java, type the following in a command line environment:
$ java -version
If you have the Java SE Runtime Environment installed, the output will look similar to the following:
$ java -version Java version "1.8.x" (or a higher version) Java<TM> SE Runtime Environment ...
If you don’t see something like this, you need to install the Java SE runtime.
Once the Java SE Runtime is installed, you may download the Commander JAR file
After downloading the latest
web-api-commander.jar file from GitHub, help is available from the command line by passing
--help or just passing no arguments, as follows:
$ java -jar path/to/web-api-commander.jar
Doing so displays the following information:
usage: java -jar web-api-commander --bearerToken <b> Bearer token to be used with the request. --clientId <d> Client Id to be used with the request. --clientSecret <s> --contentType <t> Results format: JSON (default), JSON_NO_METADATA, JSON_FULL_METADATA, XML. --entityName <n> The name of the entity to fetch, e.g. Property. --generateDDAcceptanceTests Generates acceptance tests in the current directory. --generateMetadataReport Generates metadata report from given <inputFile>. --generateQueries Resolves queries in a given RESOScript <inputFile> and displays them in standard out. --generateReferenceDDL Generates reference DDL to create a RESO-compliant SQL database. Pass --useKeyNumeric to generate the DB using numeric keys. --generateReferenceEDMX Generates reference metadata in EDMX format. --getMetadata Fetches metadata from <serviceRoot> using <bearerToken> and saves results in <outputFile>. --help print help --inputFile <i> Path to input file. --outputFile <o> Path to output file. --runRESOScript Runs commands in RESOScript file given as <inputFile>. --saveGetRequest Performs GET from <requestURI> using the given <bearerToken> and saves output to <outputFile>. --serviceRoot <s> Service root URL on the host. --uri <u> URI for raw request. Use 'single quotes' to enclose. --useEdmEnabledClient present if an EdmEnabledClient should be used. --useKeyNumeric present if numeric keys are to be used for database DDL generation. --validateMetadata Validates previously-fetched metadata in the <inputFile> path.
When using commands, if required arguments aren’t provided, relevant feedback will be displayed in the terminal.
The RESO Commander only supports passing OAuth2 “Bearer” tokens from the command line at this time. For those using OAuth2 Client Credentials, please see the section on Running RESOScript files.
To get metadata from a given server, use the
--getMetadata argument with the following
$ java -jar path/to/web-api-commander.jar --getMetadata --serviceRoot https://api.server.com/serviceRoot --outputFile metadata.xml --bearerToken abc123
serviceRoot is the path to the root of the OData WebAPI server.
Assuming everything goes well, metadata will be retrieved from the host
and written to the provided
--outputFile, and the following output will be displayed:
Requesting metadata from: https://api.server.com/serviceRoot/$metadata Metadata request succeeded.
Validating Metadata stored in an EDMX file
Sometimes it’s useful to validate a local OData XML Metadata (EDMX) file.
Since parsing EDMX is an incremental process, validation terminates each time invalid items are encountered. Therefore, the workflow for correcting an EDMX document that contains errors would be to run the Commander repeatedly, fixing errors that are encountered along the way.
To validate metadata that’s already been downloaded, call Commander with the following options,
--inputFile path for your environment accordingly:
$ java -jar path/to/web-api-commander.jar --validateMetadata --inputFile '/src/main/resources/RESODataDictionary-1.7.xml'
XML or OData validation errors will be displayed if any issues were found. If successful, the following message should appear:
Checking Metadata for validity... Valid Metadata!
Saving Results from a Given
--saveGetRequest action makes a request to a
--uri using a given
--bearerToken, and saves the response to the given
$ java -jar build/libs/web-api-commander.jar --saveGetRequest --uri 'https://api.server.com/OData/Property?$filter=ListPrice gt 100000&$top=100' --bearerToken abc123 --outputFile response.json
If the response is successful, it will be written to the specified file and the following will be displayed on the console:
JSON Data fetched from: https://api.server.com/OData/Property?$filter=ListPrice gt 100000&top=100" with response code: 200 JSON Response saved to: response.json
Otherwise, errors will be displayed showing what went wrong during the request.
Displaying Queries for RESOScript Files
A RESOScript file usually contains a server’s service root and one or more Requests that can either be used in batch-format or can be used during testing.
To resolve all parameters and display the queries to be run with your RESOScript, use the following command:
$ java -jar web-api-commander.jar --generateQueries --inputFile /path/to/your.resoscript
This should display something similar to the following:
============================================================== Web API Commander Starting... Press <ctrl+c> at any time to exit. ============================================================== Displaying 44 Request(s) RESOScript: src/test/resources/mock.web-api-server.core.2.0.0.resoscript ============================================================== =========================== Request: #1 =========================== Request Id: metadata-validation Resolved URL: https://api.reso.org/OData/$metadata =========================== Request: #2 =========================== Request Id: fetch-by-key Resolved URL: https://api.reso.org/OData/Property('12345')?$select=ListingKey ...
Running RESOScript Files
The Web API Commander is able to run files written using RESO’s XML-based scripting format, also known as a RESOScript.
In order to run an RESOScript file, use a command similar to the following:
$ java -jar out/web-api-commander.jar --runRESOScript --inputFile /path/to/your/inputFile
A results directory will be created from the RESOScript name and timestamp when it was run, and output will be shown as the requests are made.
Results will be saved to the filenames specified in the given RESOScript, and error files will be created when there are exceptions, with an “.ERROR” extension appended to them.
