Ruby Faceplusplus识别身份证,ocr,idcard,faceid,

供以后参考。

值得一提的是，就使用curl 来提交文件即可。不要使用 restclient 等ruby第三方包。因为发现这些都对post 请求支持的不好。对添加附件支持的不好。

代码如下：

def check_id_card options
  id_card_approval = options[:id_card_approval]
  type = options[:type]
  id_card_full_path = id_card_approval.send type

  url = 'https://api-cn.faceplusplus.com/cardpp/v1/ocridcard'

  api_key = 'xr4IiPXr8K9wxd1UeV42HmhAppO8QGis'
  api_secret = 'yA6bf25mtdFPdyrbamLmrVB0yiGrL1Yg'

  id_card_full_path = id_card_full_path.gsub('/public', 'public')

  command = %Q{curl -X POST "#{url}" \
  -F "api_key=#{api_key}" \
  -F "api_secret=#{api_secret}" \
  -F "image_file=@#{id_card_full_path}"}

  $logger.info "== command: #{command}"
  response = `#{command}`
  $logger.debug "---- response: #{response}"

  if response.blank? || JSON.parse(response)['cards'].blank?
    $logger.info "== invalid card: |#{response}|"

    # 这里用的是元编程．．．．好吧，注释比代码多．
    #  front, back, man
    id_card_approval.send "#{type}_checked_at=", Time.now
    id_card_approval.save!
    return
  end
