我有一个 AWS Lambda 函数可以触发对 Google API 的 https 请求。我希望该函数是可等待的,以便它不会立即结束,而只是在从 Google API 获得响应之后。是的,我知道我为执行付费,但这不会经常调用,所以没关系。
问题是 http 请求似乎没有正确触发。回调永远不会执行。
我通过在 Promise 中使用 setTimeout 确保异步/等待按预期工作。所以问题出在 https.request 中。
另请注意,我正在使用 Pulumi 部署到 AWS,因此其中可能存在一些隐藏问题。我只是不知道在哪里。

调用 Google API 的 AWS Lambda
import config from '../../config';
import { IUserInfo } from '../../interfaces';
const https = require('https');
function sendHttpsRequest(options: any): Promise<any> {
console.log(`sending request to ${options.host}`);
console.log(`Options are ${JSON.stringify(options)}`);
return new Promise(function (resolve, reject) {
console.log(` request to ${options.host} has been sent A`);
let body = new Array<Buffer>();
const request = https.request(options, function (res: any) {
console.log('statusCode:', res.statusCode);
console.log('headers:', res.headers);
if (res.statusCode != 200) {
reject(res.statusCode);
}
res.on('data', (data: any) => {
console.log(`body length is ${body.length}`);
console.log('data arrived', data);
body.push(data);
console.log('pushed to array');
console.log(data.toString());
});
});
request.on('end', () => {
console.error('Request ended');
// at this point, `body` has the entire request body stored in it as a string
let result = Buffer.concat(body).toString();
resolve(result);
});
request.on('error', async (err: Error) => {
console.error('Errooooorrrr', err.stack);
console.error('Errooooorrrr request failed');
reject(err);
});
request.end();
console.log(` request to ${options.host} has been sent B`);
});
