问题 I tried to sole this problem myself for a few days searching on examples and documentations, also it wasn't solved on ruSO. So, I hope that solution will be found here, on enSO. I develop a service for automatic creation of ads at Vk social network using Python and Google App Engine. Initially, pictures for ads are loaded to my server ( part 1 ), then they are uploaded to Vk server at some time ( parts 2.1 and 2.2 ). It seems that pictures are loaded and stored on my server correctly (I

问题 I want to convert pdfs to image files within appengine. Ideally I would upload the pdf as a blob and store both the pdf and an image of the pdf. The conversion could also be done at a different time (taskqueue). I have not found any working samples or good documentation of doing this. The official documentation is here. Here is my implementation on my upload servlet. @SuppressWarnings("serial") public class UploadBlobServlet extends HttpServlet { private static final Logger log = Logger

问题 Is it possible to share a model through other apps? if possible, how to do this. Yeah, maybe we can implement API for those apps, But if apps can share their models for each other without any external libs, it would be cool :-) 回答1: You could possibly broaden your definition of "other applications" in the original question to include other versions of the same application (where these versions are really your "other applications"). If so, then this could be possible by deploying each of your

问题 I am exploring GAE with nconf and I'm wondering if the following setup is secured after I deploy an App. What concerns me is are both my "config.dev.json" and "config.prod.json" files deployed despite including them in ".gitignore". I am unsure what information is passed along to gae (I don't want my config keys exposed) after I do: $ git add . $ git commit -m 'Commiting' $ glcoud app deploy My Node App structure looks like this: - /myProject - /node_modules - .gitignore - app.js - app.yaml -

问题 Can different microservices in GAE, own dedicated cron jobs? Background We have written multiple services on GAE microservices application. One micronservice say Service1(default) [JAVA in GAE Standard environment] has 10 cron jobs, wheareas another microservice say, Service2 [Python in GAE Flexible environment] has 5 other cronjobs. When we deploy both the services, cron jobs get replaced with the latest service cron jobs. I know that Task Queue is shared resource in GAE Microservices and

问题 I know others have posted similar issues but after trying their solutions I think this is a different problem. I'm trying to get a multi-module application functioning for Google App Engine. I'm developing it from this sample code. I was able to get my application running successfully in the development server but I encountered the following error when I tried to upload to Google App Engine with the command mvn appengine:update : Error Details: Nov 05, 2014 10:23:51 AM org.apache.jasper.JspC
