我正在尝试部署示例天气对话框流聊天机器人,
我按照对话框流程手册中的说明部署它
用于部署index.js我正在使用以下命令
gcloud beta functions deploy helloHttp --stage-bucket weather-example --trigger-http
部署文件后,我收到以下错误
ERROR: (gcloud.beta.functions.deploy) OperationError: code=3, message=Function load error: Node.js module defined by file index.js is expected to export function named helloHttp
我不知道如何解决它,我是谷歌云和对话流的新手,
这是我的index.js文件我刚刚添加了我的api密钥
'use strict';
const http = require('http');
const host = 'api.worldweatheronline.com';
const wwoApiKey = 'MY wheather key';
exports.weatherWebhook = (req, res) => {
// Get the city and date from the request
let city = req.body.queryResult.parameters['geo-city']; // city is a required param
// Get the date for the weather forecast (if present)
let date = '';
if (req.body.queryResult.parameters['date']) {
date = req.body.queryResult.parameters['date'];
console.log('Date: ' + date);
}
// Call the weather API
callWeatherApi(city, date).then((output) => {
res.json({ 'fulfillmentText': output }); // Return the results of the weather API to Dialogflow
}).catch(() => {
res.json({ 'fulfillmentText': `I don't know the weather but I hope it's good!` });
});
};
function callWeatherApi (city, date) {
return new Promise((resolve, reject) => {
// Create the path for the HTTP request to get the weather
let path = '/premium/v1/weather.ashx?format=json&num_of_days=1' +
'&q=' + encodeURIComponent(city) + '&key=' + wwoApiKey + '&date=' + date;
console.log('API Request: ' + host + path);
// Make the HTTP request to get the weather
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
let response = JSON.parse(body);
let forecast = response['data']['weather'][0];
let location = response['data']['request'][0];
let conditions = response['data']['current_condition'][0];
let currentConditions = conditions['weatherDesc'][0]['value'];
// Create response
let output = `Current conditions in the ${location['type']}
${location['query']} are ${currentConditions} with a projected high of
${forecast['maxtempC']}°C or ${forecast['maxtempF']}°F and a low of
${forecast['mintempC']}°C or ${forecast['mintempF']}°F on
${forecast['date']}.`;
// Resolve the promise with the output text
console.log(output);
resolve(output);
});
res.on('error', (error) => {
console.log(`Error calling the weather API: ${error}`)
reject();
});
});
});
}
你可以告诉我这里出了什么问题吗?

根据您的 index.js 文件,您要导出名为javascript函数的 weatherWebhook ,因此您应该放置部署函数名称的值GCloud beta函数deploy
命令的属性与导出的方法名称相同,因为默认情况下触发Google Cloud Function时,它会执行具有相同名称的JavaScript函数,或者如果找不到具有相同名称的函数,则执行名为function
的函数。
为此你的命令就是,试试这个
gcloud beta functions deploy weatherWebhook --stage-bucket weather-example --trigger-http
或强>
如果您希望部署名称不同,可以使用 - 入口点参数告诉gcp哪个函数将成为您的Google云功能的入口点。
gcloud beta functions deploy helloHttp --entry-point weatherWebhook --stage-bucket weather-example --trigger-http

你好朋友我错误地使用了错误的部署网址, 正确的网址如下:
gcloud beta functions deploy helloHttp --entry-point weatherWebhook --stage-bucket weather-example --trigger-http
