Suppose that you need to consume the following REST web service in your GeneXus application:
http://labs.genexus.com/mobilecrm/rest/WorkWithDevicesCompany_Company_List_Grid?fmt=json
where its response is in JSON format and looks as follows:
[{"CompanyId":"1","CompanyLogo":"PublicTempStorage\/image\/gx_upl_a7473480b990012f68a412313d236401.tmp","CompanyName":"Adobe"},
{"CompanyId":"14","CompanyLogo":"PublicTempStorage\/image\/gx_upl_f38b1930f3ff012fc28e12313d236401.tmp","CompanyName":"Apple"}]
To consume it in GeneXus:
1. Define a Structured Data Type object as follows:
2. Write the following code in your GeneXus object (use HttpClient data type):
&httpclient.Host = "labs.genexus.com"
&httpclient.BaseUrl = "/mobilecrm/rest/"
&httpclient.Execute('GET','WorkWithDevicesCompany_Company_List_Grid?fmt=json')
&companies.FromJson(&httpclient.ToString() )
Where:
&htttpclient is a HttpClient data type variable and
&companies is a collection variable based on the Structured Data Type defined previously.
3. Finished! You already have your companies loaded in your &companies variable
