我是对话流实现的新手,我正在尝试根据用户问题从新闻 API 中检索新闻。我遵循新闻 API 提供的文档,但无法从搜索结果中捕获任何响应,当我在控制台中运行该函数时,这不是错误。我更改了代码,看起来现在它已经到达 newsapi 端点,但没有获取任何结果。我正在利用https://newsapi.org/docs/client-libraries/node-js请求搜索有关该主题的所有内容。当我诊断该函数时,它显示“Webhook 调用失败。错误:不可用。”
'use strict';
const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
const http = require('http');
const host = 'newsapi.org';
const NewsAPI = require('newsapi');
const newsapi = new NewsAPI('63756dc5caca424fb3d0343406295021');
process.env.DEBUG = 'dialogflow:debug';
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((req, res) =>
{
// Get the city
let search = req.body.queryResult.parameters['search'];// search is a required param
// Call the weather API
callNewsApi(search).then((response) => {
res.json({ 'fulfillmentText': response }); // Return the results of the news API to Dialogflow
}).catch((xx) => {
console.error(xx);
res.json({ 'fulfillmentText': `I don't know the news but I hope it's good!` });
});
});
function callNewsApi(search)
{
console.log(search);
newsapi.v2.everything
(
{
q: 'search',
langauge: 'en',
sortBy: 'relevancy',
source: 'cbc-news',
domains: 'cbc.ca',
from: '2019-12-31',
to: '2020-12-12',
page: 2
}
).then (response => {console.log(response);
{
let articles = response['data']['articles'][0];
// Create response
let responce = `Current news in the $search with following title is ${articles['titile']} which says that
${articles['description']}`;
// Resolve the promise with the output text
console.log(output);
}
});
}
这里还有 RAW API 响应

这是履行请求:

任何人都可以指导我,我在这里缺少什么吗?
最佳答案
关键是错误信息的前三行:
Function failed on loading user code. Error message: Code in file index.js can't be loaded.
Did you list all required modules in the package.json dependencies?
Detailed stack trace: Error: Cannot find module 'newsapi'
它表示无法加载 newsapi
模块,最可能的原因是您没有将其列为 package.json< 中的依赖项
文件。
如果您使用的是 Dialogflow 内联编辑器,则需要选择 package.json
选项卡并在 dependencies
部分中添加一行。
更新
目前尚不清楚您何时何地收到“不可用”错误,但如果您使用 Dialogflow 的内联编辑器,一个可能的原因是它使用的是具有限制的 Firebase“Spark”定价计划在 Google 网络之外的网络调用上。
您可以upgrade to the Blaze plan ,这确实需要存档信用卡,但包含 Spark 计划的免费套餐,因此您在少量使用期间不应产生任何费用。这将允许网络调用。
更新基于TypeError:无法读取未定义的属性“0”
这表明属性(或者可能是属性的索引)正在尝试引用未定义的内容。
目前尚不清楚这可能是哪一行,但这些行都是可疑的:
let response = JSON.parse(body);
let source = response['data']['source'][0];
let id = response['data']['id'][0];
let name = response['data']['name'][0];
let author = response['author'][0];
let title = response['title'][0];
let description = response['description'][0];
因为它们都引用一个属性。我会检查到底返回了什么并存储在响应中。例如,发回的内容中是否没有“数据”或“作者”字段?
查看 https://newsapi.org/docs/endpoints/everything ,看起来这些都不是字段,但有一个发送回的articles
属性,其中包含一个文章数组。您可能希望对其进行索引并获取所需的属性。
更新
看起来就像这样,尽管您正在使用此行将参数加载到变量中
// Get the city and date from the request
let search = req.body.queryResult.parameters['search'];// city is a required param
您实际上并没有在任何地方使用 search
变量。相反,您似乎使用此行将文字字符串“search”传递给您的函数
callNewsApi('search').then((output) => {
我猜它会搜索“搜索”这个词。
您表示“它进入 catch 部分”,这表明调用中出现了问题。您不会在 catch 部分显示任何日志记录,并且记录引发的异常可能很有用,因此您知道为什么它会进入 catch 部分。类似的东西
}).catch((xx) => {
console.error(xx);
res.json({ 'fulfillmentText': `I don't know the news but I hope it's good!` });
});
这是正常的,但由于您似乎将其记录在 .on('error')
部分,因此显示该错误可能会很有用。
