国政通身份证认证

Gemfile里添加

gem 'savon', '~> 2.12.0'

# 国政通参数加密

  def encrypt(str, key = 'XXXX')

    cipher = OpenSSL::Cipher.new("DES")

    cipher.encrypt

    cipher.key = key

    cipher.iv = key

    result = cipher.update(str.encode('gb18030','utf-8'))

    result << cipher.final

    Base64.encode64(result).strip

  end

  def decrypt(str, key: 'XXXX')

    cipher = OpenSSL::Cipher.new("DES")

    cipher.decrypt

    cipher.key = key

    cipher.iv = key

    result = cipher.update(Base64.decode64(str)) + cipher.final

    result

  end

调用国政通接口

client = Savon.client(wsdl: 'http://xxxxxxx?wsdl')

      response = client.call(:query_single, message: { username_: encrypt("xxx"),

                                                      password_: encrypt("xxx"),

                                                      type_: encrypt("xxx"),

                                                      param_: encrypt("姓名,身份证号").encode('utf-8','gb18030') })

      result = response.body[:query_single_response][:query_single_return]

      doc = Nokogiri.XML(decrypt(result))

      data_status = doc.xpath('/data/message/status[1]').text

      return false if data_status != "0"

      policeCheckInfo_status = doc.xpath('/data/policeCheckInfos/policeCheckInfo/message/status[1]').text

      # policeCheckInfo_value = doc.xpath('/data/policeCheckInfos/policeCheckInfo/message/value[1]').text.encode('utf-8','gb18030')

      return false if policeCheckInfo_status != "0"

      compStatus = doc.xpath('/data/policeCheckInfos/policeCheckInfo/compStatus[1]').text

      # compResult = doc.xpath('/data/policeCheckInfos/policeCheckInfo/compResult[1]').text.encode('utf-8','gb18030')

      name = doc.xpath('/data/policeCheckInfos/policeCheckInfo/name[1]').text.encode('utf-8','gb18030')

      if compStatus == "3"

         认证通过

      end

国政通编码为gb18030，在加密参数的时候记得转换编码。
