I need your help 我需要你的帮助
Cloud functions are expected to return something meaningful, most often you'd want to return a Promise
. 期望云函数返回有意义的东西,大多数情况下,您通常希望返回Promise
。 That way the engine will know that your async operations have finished and doesn't have to wait for a timeout to happen. 这样,引擎将知道您的异步操作已经完成,而不必等待超时发生。
To fix your code, just return a Promise
: 要修复您的代码,只需返回Promise
:
return new Promise((resolve, reject) => {
request(options, function (error, response, body) {
if (error) reject(error);
else resolve(response);
});
});
