Webhook 允许 GET 方法

Question

根据文档，

"When an intent in which a webhook was enabled is triggered, Dialogflow sends data to the service in the form of POST request with a POST body in the format of response to a query."

所以我假设 GET 请求是不可能的...不是吗？

在 Postman 中，我可以使用我的代码发出 GET 请求，但是在部署到 Heroku 并在 fulfillment 部分设置 URL 之后，除了 [=22] 之外，我无法得到任何正确的响应=].

非常感谢。

这是代码。这是我第一次尝试使用 Node :-)

const express = require('express');
const bodyParser = require('body-parser');
const http = require('https');
var port = process.env.PORT || 8080;

const server = express();


server.use(bodyParser.json());

server.post('/get-movie-details', function (req, res) {

    //This line is crashing the app in Heroku from Dialogflow. Paramaters are not correctly passed
    let movieToSearch = req.body.result.parameters.query;

    let finalurl = encodeURI('https://api.themoviedb.org/3/search/movie?api_key=c21ed50674dabf90143d1136bf9279ae&language=en-US&query=' + req.body.result.parameters.query + '&page=1&include_adult=false');

    console.log('This is the finalUrl: ' + finalurl);

    http.get(finalurl, (responseFromAPI) => {

        responseFromAPI.on('data', function (chunk) {

            let movie = JSON.parse(chunk)['results'][0];


            let dataToSend = movie.original_title  + ' is a ' + movie.vote_average + ' vote average  released in ' + movie.release_date + '. Maybe you want some more information?';

            return res.json({
                speech: dataToSend,
                displayText: dataToSend,
                source: 'The movieDataBase'
            });

        });
    }, (error) => {
        return res.json({
            speech: 'Something went wrong!',
            displayText: 'Something went wrong!',
            source: 'get-movie-details'
        });
    });
});

 server.listen(port);
 console.log('Server started! At https://localhost:' + port);

正确，GET 请求是不可能的。发送的 JSON 的大小很容易超过 GET 允许的 URL 长度。
