paiza.ioでelixir その77

概要

paiza.ioでelixirやってみた。
e-statのsparqlを叩いてみた。

サンプルコード

:inets.start
:ssl.start

query = URI.encode_query(%{query: """

SELECT ?subject ?predicate ?object
WHERE {
    ?subject ?predicate ?object
}
LIMIT 3

"""})
#|> IO.inspect
{:ok, {{_, _, _}, _, body}} = :httpc.request(:post, {
	'https://data.e-stat.go.jp/lod/sparql/alldata/query', 
	[{'Accept', 'application/sparql-results+json'}], 
	'application/x-www-form-urlencoded', 
	query
}, [], [])
#|> IO.inspect
body = IO.iodata_to_binary(body)
IO.puts(body)

実行結果

{
  "head": {
    "vars": [ "subject" , "predicate" , "object" ]
  } ,
  "results": {
    "bindings": [
      {
        "subject": { "type": "uri" , "value": "http://data.e-stat.go.jp/lod/dataset/gridCode/dm012015302/obsQ24DSKRZDMDOMMQ7TRTQI5FT4PMVNYLM" } ,
