Webhook呼叫失敗。 錯誤：500內部服務器錯誤| Dialogflow | 火力地堡

Question

我正在嘗試創建一個firebase函數，使用履行webhook將API響應發送到dialogflow，但我面臨的錯誤：500。

const functions = require('firebase-functions');
var request = require('request')

exports.webhook = functions.https.onRequest((request, response) => {

        console.log("request.body.result.parameters: ", request.body.result.parameters);
        let params = request.body.result.parameters;

        var options = {
            url: `https://islam360api.herokuapp.com/${params.find}`,
            json:true
        }
        request(options, function(error, response, body){
            if(error) response.send(error);
            else response.send(body);
        });
    });

我在部署時得到的警告是

  13:26  warning  Unexpected function expression  prefer-arrow-callback

✖ 1 problem (0 errors, 1 warning)
  0 errors and 1 warning potentially fixable with the `--fix` option.

例如，如果params.find是evoke那么解析API響應應該給出這個結果

https://islam360api.herokuapp.com/evoke

{"speech":"In Surat-ul-Fateha, Ayat Number: 7, Quran says:  not of those who have evoked [Your] anger or of those who are astray. ","displayText":"In Surat-ul-Fateha, Ayat Number: 7, Quran says:  not of those who have evoked [Your] anger or of those who are astray. "}

編輯：這是我在部署firebase功能時得到的響應

Firebase日志

從firebase日志看來，我必須付錢。 我一定要嗎？

Answer 1

如果您使用的是dialogflow v2：

 request(options, function(error, response, body){
     if(error) 
         response.send({ fulfillmentText: "error in api call"});
     else 
         response.send({ fulfillmentText: body.speech });
 });

如果你正在使用dilogflow v1（很快就會棄用）

 request(options, function(error, response, body){
     if(error) 
         response.send({ speech: "error in api call"});
     else 
         response.send({ speech: body.speech });
 });

檢查/更改對話框流量版本，轉到dilogflow控制台（ https://console.dialogflow.com ），按齒輪圖標，然后在常規部分查看，不要忘記按保存按鈕以防萬一

更新

根據你的firebase功能日志，你需要支付，

請注意，firebase功能只允許調用谷歌api，並且不允許第三方api免費配額，你需要將你的計划轉移到“按需付費”，因為它是最便宜的

或者，你可以使用快速服務器制作webhook，你可以將它部署在heroku雲上，它們允許在他們的免費計划中使用第三方api呼叫
