验签

后台通知验签，本例使用 koa 和 koa-better-body

const uniondocpay = new Uniondocpay(...);

public webhook = async (ctx: IContext) => {
  try {
    if (!uniondocpay.verify(ctx.request.fields)) throw new Error('签名错误');
    // 这里处理支付成功
    ctx.status = 200;
    ctx.body = 'SUCCESS';
  } catch (e) {
    console.error(e);
    ctx.body = 'FAIL';
  }
};
