node.js - response.send 不是函数

Question

我正在编写一个 Firebase 函数，用于实现对话流聊天机器人的 Webhook。它不断生成错误，response.send不是一个函数

const functions = require('firebase-functions');
var request1 = 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
        }
        request1(options, function(error, response, body){
            if(error) response.send({speech: "error in API call"});
            else response.send({speech: body.speech});
        });
    });

Answer 1

问题:这是影子变量名称的问题，当您尝试使用 firebase 函数响应对象发送响应时，实际上您正在将响应发送回 npm 请求模块的响应对象，这当然是不可能的

解决方案: 只需添加下划线或更改拼写，就可以开始了，看看代码: (注意从底部算起第五行的变化)

const functions = require('firebase-functions');
var request1 = 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
        }
        request1(options, function(error, _response, body){
            if(error) response.send({speech: "error in API call"});
            else response.send({speech: body.speech});
        });
    });
