Question

我的意图是调用了cheerio.load（），并且使响应混乱。 Google助手不断告诉我，即使稍后在我有回复的代码中也没有设置任何回复。控制台还告诉我没有将异步调用返回给处理程序，我相信它是cheerio.load（）。无论如何，我可以解决此问题，以便它继续在代码底部寻找正确的conv.ask吗？它仍然继续向下运行，直到显示console.log（map）。感谢您的帮助！

func createTreatNode() {
    let atlas = SKTextureAtlas(named: "Treat")
    let q1 = atlas.textureNamed("treat1.png")
    let q2 = atlas.textureNamed("treat2.png")
    let q3 = atlas.textureNamed("treat3.png")
    let treatAnimation = [q1, q2, q3]
    let treat = SKSpriteNode(texture: q1)
    treat.position = CGPoint(x: 1000, y: 150)
    print("treat position \(treat.position)")
    treat.size = CGSize(width: 60, height: 50)
    treat.name = "Treat"
    let animate = SKAction.animate(with: treatAnimation, timePerFrame: 0.2)
    let repeatAction = SKAction.repeatForever(animate)
    treat.run(repeatAction)
    let body = SKPhysicsBody(rectangleOf: treat.size)
    body.usesPreciseCollisionDetection = true
    body.affectedByGravity = false
    body.collisionBitMask = 0x7FFFFFFF
    body.contactTestBitMask = 0x80000000
    treat.physicsBody = body
    addChild(treat)
}

}）;

我已修改您的代码以返回Promise。检查是否适合您。

app.intent("late drop", (conv, {
  term,
  year
}) => {

  return new Promise(function (resolve, reject) {

    var date = new Date();
    var month;
    if (term == null) {
      month = date.getMonth();

      if (month >= 9 && month <= 12) {
        term = "fall";
        //console.log("fall")
      } else if (month >= 1 && month <= 5) {
        term = "spring";
        //console.log("spring")
      } else {
        term = "summer";
        //console.log("summer")
      }
    }
    if (year == null) {
      yearDig = date.getFullYear();
      year = yearDig;
      //console.log(year)
    }
    var strYear = year.toString();
    var semester = term + strYear.substr(2);
    const options = {
      uri: `https://www.registrar.psu.edu/academic_calendar/${semester}.cfm`,
      transform: function (body) {
        return cheerio.load(body);
      }
    };
    rp(options)
      .then(($) => {
        let map = {};
        let columnOne = [];
        let columnThree = [];

        $('table').find('tr td:nth-child(1)').each(function (index, element) {
          columnOne.push($(element).text());
        });

        $('table').find('tr td:nth-child(3)').each(function (index, element) {
          columnThree.push($(element).text());
        });

        columnOne.forEach((item, i) => {
          map[item] = columnThree[i];
        });

        console.log(map);
        date = map["2Late Drop Begins"];
        conv.ask("The late drop period begins on " + map["2Late Drop Begins"])
        resolve()
      })
      .catch((error) => {
        console.log(error);
        conv.ask("An error occured, please try again.");
        reject()
      })
  });

});

希望有帮助！

问题不在于欢乐。

您似乎正在使用request-promise或request-promise-native进行HTTP调用。这将执行异步操作，该操作将返回Promise（如您使用.then()和.catch()所证明。

由于执行异步操作的Intent处理程序必须返回一个Promise，因此您只需返回rp / then / catch链返回的那个。像更改此行这样的东西应该起作用：

return rp(options)

Cheerio.load弄乱了Google Assistant的响应
