Exposing Data as REST-Style Resources

This sample demonstrates how data can be exposed as REST resources through a data service and also how the service can be invoked in REST style.

About the sample

This sample scenario is based on a database that stores information about the products of an enterprise. There are separate queries/resources written for specific tasks of the products. Resources are defined in order to access data through REST calls. The resources implemented by the service are listed below. 

• Create Product - Use HTTP POST request to insert new products. 
  Resource Path : product 
  Resource Method : POST

• Update Product - Use HTTP PUT request to update product information. 
  Resource Path : product 
  Resource Method : PUT

• GET Product - Use HTTP GET request to retrieve product information for a given product code. 
  Resource Path : product/{productCode} 
  Resource Method : GET

• Get All Products - Use HTTP GET request to get all the products. 
  Resource Path : products 
  Resource Method : GET
  
  
• Delete Product - Use HTTP DELETE request to delete a given product from the database. 
  Resource Path : product/{productCode} 
  Resource Method : DELETE

See Data Services and Resources for details.

Building the sample

The sample data service ResourcesSample should be deployed using the instructions in Samples Setup.

Running the sample

The service can be invoked in REST-style via curl (http://curl.haxx.se). The following commands can be executed using the command line to invoke each of the resources.

• Create Product
  

  curl -X POST -d '<product><productCode>S10_100</productCode><productName>1969 Harley Davidson Ultimate Chopper</productName><productLine>Motorcycles</productLine><quantityInStock>7933</quantityInStock><buyPrice>48.81</buyPrice></product>' --header 'Content-Type: application/xml' http://localhost:9763/services/samples/ResourcesSample.HTTPEndpoint/product

• Update Product
  

  curl -X PUT -d '<product><productCode>S10_100</productCode><productName>1969 Harley Davidson Ultimate Chopper</productName><productLine>Motorcycles</productLine><quantityInStock>8000</quantityInStock><buyPrice>48.81</buyPrice></product>' --header 'Content-Type: application/xml' http://localhost:9763/services/samples/ResourcesSample.HTTPEndpoint/product 

• GET Product
  

  curl -X GET http://localhost:9763/services/samples/ResourcesSample.HTTPEndpoint/product/S10_100 

• Get All Products
  

  curl -X GET http://localhost:9763/services/samples/ResourcesSample.HTTPEndpoint/products

• Delete Product
  

  curl -X DELETE http://localhost:9763/services/samples/ResourcesSample.HTTPEndpoint/product/S10_100
