我正在使用Firebase和Firebase的新功能Cloud Functions构建Web应用程序。我创建了一个函数,它使用一个URL并使用节点模块请求和request-promise-native将图像下载到一个64位编码的字符串中,如下所示:
module.exports = {
downloadImageFromUrl: function (url) {
var options = {
method: 'GET',
uri: url,
resolveWithFullResponse: true,
simple: false,
family: 4
};
return rp.get(options)
.then(function (res) {
return "data:" + res.headers["content-type"] + ";base64," + new Buffer(res.body).toString('base64');
})
.catch(function (error) {
console.log("ERROR GETTING image", error);
return error;
});
}
};
top函数在本地完美运行,但一旦在firebase上它就会出错:
RequestError: Error: getaddrinfo EAI_AGAIN lh6.googleusercontent.com:443
at new RequestError (/user_code/node_modules/request-promise/node_modules/request-promise-core/lib/errors.js:14:15)

我在如下创建用户时调用firebase auth触发器中的函数:
exports.createUser = functions.auth.user().onCreate(event => {
if (event.data.photoURL) {
utils.downloadImageFromUrl(event.data.photoURL)
.then(function(res){
console.log("User Photo", res);
})
.catch(function(error){
console.log("Error", error);
})
}
});
非常感谢任何帮助。

如果这是答案,还不完全确定,但在阅读文档后,我阅读了他们的免费计划,该计划表明你无法提出任何约束请求。所以我想从Url获取图像算作出站请求。在我开始支付他们的服务费用之后,我会回来验证这是否是问题。
