调用示例

在云函数中调用

// 云函数中使用云调用无需引入其他依赖，只需要使用ctx.cloud调用
module.exports = async function (ctx) {
  const res = await ctx.cloud.payment.faceToFace.pay({
    // 参数接收自云函数调用端传入的参数
    subject: ctx.args.subject,
    outTradeNo: ctx.args.outTradeNo,
    totalAmount: ctx.args.totalAmount,
    authCode: ctx.args.authCode
  });
  return res;
};

支持传入notifyUrl接收支付宝服务器交易通知

// 云函数中使用云调用无需引入其他依赖，只需要使用ctx.cloud调用
module.exports = async function (ctx) {
  const res = await ctx.cloud.payment.faceToFace.pay({
    // 参数接收自云函数调用端传入的参数
    subject: ctx.args.subject,
    outTradeNo: ctx.args.outTradeNo,
    totalAmount: ctx.args.totalAmount,
    authCode: ctx.args.authCode
  }, {
    // 传入接收支付宝服务器交易通知的http/https路径，也可以是云函数的http触发路径
    notify: {
        url: 'http://api.test.alipay.net/atinterface/receive_notify.htm'
    }
  });
  return res;
};

支持传入appAuthToken进行三方代调用

// 云函数中使用云调用无需引入其他依赖，只需要使用ctx.cloud调用
module.exports = async function (ctx) {
  const res = await ctx.cloud.payment.faceToFace.pay({
    // 参数接收自云函数调用端传入的参数
    subject: ctx.args.subject,
    outTradeNo: ctx.args.outTradeNo,
    totalAmount: ctx.args.totalAmount,
    authCode: ctx.args.authCode
   }, {    // appAuthToken参数接收自云函数调用处传入的参数
    appAuthToken: ctx.args.appAuthToken
  });
  return res;
};
