我正在尝试从iex api获取json数据。我使用的是Google对话框流的内联编辑器,当尝试从api获取json时,我一直收到错误消息:
Error: Parse Error
at Error (native)
at Socket.socketOnData (_http_client.js:363:20)
at emitOne (events.js:96:13)
at Socket.emit (events.js:188:7)
at readableAddChunk (_stream_readable.js:176:18)
at Socket.Readable.push (_stream_readable.js:134:10)
at TCP.onread (net.js:559:20)
控制台日志显示我正在请求正确的路径以获取json请求(在这种情况下,我需要Microsoft json信息
API Request: api.iextrading.com/1.0/stock/MSFT/company
我不确定为什么无法正确读取json,但我认为发生了错误,因为我的代码的主体变量未从http请求接收信息。我只是不确定我的代码有什么问题。
这是我的代码:
'use strict';
const http = require('http');
const functions = require('firebase-functions');
const host = 'api.iextrading.com';
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((req, res) => {
// Get the company
let company = req.body.queryResult.parameters['company_name']; // city is a required param
// Call the iex API
callCompanyApi(company).then((output) => {
res.json({ 'fulfillmentText': output });
}).catch(() => {
res.json({ 'fulfillmentText': `I don't know this company`});
});
});
function callCompanyApi (company) {
return new Promise((resolve, reject) => {
// Create the path for the HTTP request to get the company
let path = '/1.0/stock/' + company + '/company';
console.log('API Request: ' + host + path);
// Make the HTTP request to get the company info
http.get({host: host, path: path}, (res) => {
let body = ''; // var to store the response chunks
res.on('data', (d) => { body += d; });// store each response chunk
res.on('end', () => {
// After all the data has been received parse the JSON for desired data
console.log(body);
let response = JSON.parse(body);
let description = response['description'];
// Create response
let output = `${description}`
// Resolve the promise with the output text
console.log(output);
resolve(output);
});
res.on('error', (error) => {
console.log(`Error calling the iex API: ${error}`)
reject();
});
});
});
}

如果您使用内联对话框流编辑器,则说明您正在运行Firebase的Cloud Functions(或Firebase Cloud Functions)。默认情况下,基本计划有一个限制,即您不能在Google网络之外拨打网络电话。
要解决此问题,您可以将Firebase计划升级为诸如Blaze Plan之类的订阅。这确实需要使用信用卡,但是基本使用级别应该是免费套餐的一部分。
您还可以在其他任何地方运行Webhook,只要存在具有有效SSL证书的Web服务器即可处理HTTPS请求即可。如果要在本地运行,甚至可以使用类似ngrok的东西。
