问题 Ruby on Rails has a way that you can set a message, like flash[:notice] and flash[:error , that the user will see at the next opportunity. It’s especially useful for things like notifying the user of failure to log in, etc., when they are redirected (e.g. back to a sign-in page). Is there a canonical or common way to achieve this on Google App Engine (Python API)? (Assume Django is not being used.) 回答1: Webapp framework, the simple web application framework that ships with GAE, does not

问题 I am trying to push a Nodejs sample app Hello World but after pushing I am getting error. ERROR: (gcloud.app.deploy) Error Response: [13] An internal error occurred while creating a Google Cloud Storage bucket.

问题 I've migrated from google protobuf v. 2.4.1 to v. 2.5.0 (no other change). I had a perfectly working client-server [android<>gae dev server] communication using 2.4.1. Now with 2.5.0 it is broken. Without any modification to the .proto file, I've setup my client and server with the new 2.5.0 jar, and with the new protoc executable I've generated a new source file for client and server from the same proto file. Now I get this error on the server when I'm trying to parse the message:

问题 I am trying to deploy a python flask app to google cloud. Once the app starts running I get the following error: File "/home/vmagent/app/app.py", line 11, in <module> import cv2 File "/env/lib/python3.4/site-packages/cv2/__init__.py", line 9, in <module> from .cv2 import * ImportError: libSM.so.6: cannot open shared object file: No such file or directory Doing some research on the problem, I figured out that this seems to be a problem related to opencv-python and the following line should

问题 Google App Engine flexible environment automatically pipes stdout and stderr to Stackdriver (Google Cloud Logging). But this only supports plain text log message without any metadata (not even logging levels). I found Logback appender for google cloud logging. https://cloud.google.com/logging/docs/setup/java But this does not seem to support structured logging yet. And also, it makes GRPC calls for every log entry under the hood. So, I wonder how scalable it is (especially compare to current

问题 I would like to add Russian text to the image. I use PIL 1.1.7 and Python 2.7 on Windows machine. Since PIL compiled without libfreetype library, I use the following on development server: font_text = ImageFont.load('helvR24.pil') draw.text((0, 0), 'Текст на русском', font=font_text) ( helvR24.pil is taken from http://effbot.org/media/downloads/pilfonts.zip) On Production environment I do the following: font_text = ImageFont.truetype('HelveticaRegular.ttf', 24, encoding="utf-8") draw.text((0,

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
