API-HARVESTER

A tool for harvesting data from an api
Very generic implementation that could work for some cases that accept an offset and limit query parameters.

Usage

Harvest mode:

  • Download the directory api-harvester-run
  • Update the harvester.properties file appropriately
  • Run the .jar file java -jar api-harvester-1.0-SNAPSHOT-jar-with-dependencies.jar

It will output harvesting information on the terminal but also under the directory logs, which will be generated.

Convert mode:

Convert from json files to xml files.
usage: xml converter
-c,--convert enable only convertion of input
-d,--outputDirectoryPath <arg> output directory path
-f,--filePath <arg> file to read from
-h,--help help output
-l,--listElementNames <arg> if json is list, set the element names
-o,--outputFileName <arg> output filename
-r,--rootElementName <arg> root element name

Examples:
Convert json file located in /tmp/test.json to current directory ./ with output file name test.xml.
If json is a list and does not start with a bracket { then each element will have the tag name record
java -jar api-harvester-1.0-SNAPSHOT-jar-with-dependencies.jar -c -d ./ -o test.xml -l record -f /tmp/test.json

Run with providing a wrapper element as well: java -jar api-harvester-1.0-SNAPSHOT-jar-with-dependencies.jar -c -d ./ -o test.xml -l record -r root -f /tmp/test.json

harvester.properties
The user who runs the .jar file should have write access to the directories specified for the generation of the directories and files.
api.endpoint The api endpoint to harvest.
directory.name.prefix The directory prefix that the harvest should have, for example if it's set to harvest then the result should be something like harvest-2017_03_27_1746/.
json.convert.to.xml true or false. Convert json received data automatically to xml.
offset.parameter.name The query parameter name used for offset.
limit.parameter.name The query parameter name used for limit.
offset The value of the offset query parameter.
limit The value of the limit query parameter.
record.list.field The element that hold the list/array of the records to be extracted from the response.
