I want to create a workflow that downloads a file from the internet (SHP file compressed as ZIP file). That file should then be used in my workflow for further analysis and processing.
How should I set that up? I now have a "Creator", followed by a 'HTTPCaller'. This HTTPCaller downloads my ZIP file (contains a SHP file). How can I now use this data for further processing? When I use a ESRI SHP File Reader, I can't seem to send this file as an input to that Reader?
+13You can use the transformer FeatureReader to read your SHP-File after download.

Also make sure your are saving your response body to a file/folder. The path you pass to the FeatureReader will be the "_reponse_file_path" attribute

If you don't want to save the response body permanently, insert a TempPathnameCreator before the HTTPCaller. Store the downloaded zip file in the path created by this transformer. That way, the downloaded data will automatically be removed at the end of the workspace.

FeatureReader does the trick! That's an awesome transformer. Thanks.

Good tip, thanks, just what I needed.

Great suggestion too. Learning so much today!

When I do the same, I end up having to expose the attributes after the feature reader using an AttributeExposer, is that intended? Is there a setting in the feature reader i should be utilizing to avoid this?
