Send JSON POST request to 'http://index_service_ip:8001'
JSON format:
Input: {'task' : 'getSuggestions', 'word' : str} Output: {'suggestions' : ['word1', 'word2', ...]}
Input: {'task' : 'getArticles', 'word' : str} Output: {'articleID' : ['id1', 'id2', ...]}
Input: {'task' : 'getFrequencyList'} Output: {'word1' : freq_word1, 'word2' : freq_word2}
The index service requires that the publish module responds with a JSON on the form:
{"list": [{"id": id1, ""title":title1}, {"id": id2, ""title":title2}, {"id": id2, ""title":title2}, ...]}
when GET requests are sent to 'http://publish_module_ip:port_num/list'
Furthermore publish needs to send JSON POST requests to 'http://index_service_ip:8001' when an article is published, removed or updated on the form:
Input: {'task' : 'publishedArticle', 'articleID' : 'id'}
Input: {'task' : 'removedArticle', 'articleID' : 'id'}
Input: {'task' : 'updatedArticle', articleID' : 'id'}
