Does Google App Engine support ftp?

由 こ雲淡風輕ζ 提交于 2020-01-19 14:02:08
问题 Now I use my own Java FTP program to ftp objects from my PC to my ISP's website server. I want to use Google App Engine's servlet to get Paypal IPN messages, then store the messages into my own objects and ftp the objects to my ISP's website server, is this doable ? I heard Google App Engine doesn't support FTP. I don't expect Google to do it for me, but can I use my own Java FTP program in the web app that I upload onto the App Engine to do it ? Frank 回答1: No, you can't open any socket

psycopg2 error on Google App Engine

问题 I'm hosting a website/app using Flask/SQLAlchemy on Google's App Engine, part of which entails communicating with a PostgreSQL server and querying it to populate the website. The SQL server is hosted on Google's Compute Engine as a VM instance per these instructions, but with the server open to all connections. When I send a GET request to the website/app when it is hosted on localhost, I get the data I expect. However, when I launch the app and attempt to send the same request to the new URL

Google PubSub - getting last message

由 浪子不回头ぞ 提交于 2020-01-17 06:54:38
问题 I am beginning to work with google app engine and the services it offers. One service that I am particularly interested in is the cloud pubsub. My plan is to have a nodejs socket.io server which subscribes to some pubsub topic and whenever the topic receives a publish it would send that publish to all sockets. At the other end, I would have a .NET/Java service that publishes messages to various topics. My question is this - Is there a way to get the last message that was published to a topic?

Google datastore - index a date created field without having a hotspot

由 一世执手 提交于 2020-01-17 06:11:45
问题 I am using Google Datastore and will need to query it to retrieve some entities. These entities will need to be sorted by newest to oldest. My first thought was to have a date_created property which contains a timestamp. I would then index this field and sort on this field. The problem with this approach is it will cause hotspots in the database (https://cloud.google.com/datastore/docs/best-practices). Do not index properties with monotonically increasing values (such as a NOW() timestamp).
