创建 DataAPI 类访问 MSCI ESG 数据 API
class DataAPI API_VERSION = "/v2" BASE_PATH = "https://api.msci.com/esg/report" def initialize(client_id, secret_key) @client_id = client_id @secret_key = secret_key @token = nil end def self.execute(function) res = get(BASE_PATH + API_VERSION + function) puts res.body true end def auth res = post( "https://accounts.msci.com/oauth/token", { "client_id" => @client_id, "client_secret" => @secret_key, "grant_type" => "client_credentials", "audience" => "https://esg/report" } ) puts res.body response = JSON.parse(res.body) return response["error_description"] if response["error"] true endprivate def post(uri, body) uri = URI.parse(uri) https = Net::HTTP.new(uri.host, uri.port) https.use_ssl = true req = Net::HTTP::Post.new(uri.path) req.body = body.to_json req["Content-Type"] = "application/json" https.request(req) end def get(uri) uri = URI.parse(uri) https = Net::HTTP.new(uri.host, uri.port) https.use_ssl = true req = Net::HTTP::Get.new(uri.path) req["Content-Type"] = "application/json" req["Authorization"] = "Bearer #{@token}" http.request(req) end end endend
