node.js集成authorize.net支付

本文主要是介绍node.js集成authorize.net支付，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

1.申请沙箱登录账号

2.登录后，申请api凭证和密钥

                            res.message = response.getMessages().getMessage()[0].getText();    
                        }
                    }
                }else {
                    res.code = 500;
                    res.message = 'Null Response.';
                }
                resolve(res);
            });
        });
    }

}

以上都是封装好的支付和退款，直接传参调方法就完事了！

注意;测authorize.net正式环境时，要求全球通用的信用卡.
