There is nothing wrong with the code that you have presented here. 您在此处提供的代码没有错。 There must be some other code base that you must have uploaded to the App Engine. 您必须已将其他代码库上传到App Engine。 I took your code, ran it locally and deployed to the App Engine cloud too. 我获取了您的代码，在本地运行并也部署到了App Engine云中。 Everything looks good for what you want to do. 一切看起来都很适合您想做的事。
