使用Zappa部署Flask应用时出错

Question

我是zappa的新人。目前，我正在尝试使用zappa部署我的flask项目。

部署我的Flask应用程序时，我收到此错误

Traceback (most recent call last):

ParamValidationError: Parameter validation failed:
Invalid type for parameter restApiId, value: None, type: <type 'NoneType'>, valid types: <type 'basestring'>

有没有人知道为什么会出现这个错误，或者我如何解决这个问题？

Answer 1

我不太了解zappa，但错误消息清楚地说明了您的问题：

Invalid type for parameter restApiId, value: None, type: <type 'NoneType'>, valid types: <type 'basestring'>

在我看来，您还没有设置参数restApiId，它应该包含一个basestring类型的值。我不确定这个参数是关于什么的，但它似乎与AWS-CLI有关。

Answer 2

在您的aws cli中，请确保您使用的是您为zappa功能创建的IAM，然后按照访问密钥、密钥和区域的aws配置问答进行操作。我建议你遵循这个非常有用的教程，一步一步来：https://developer.amazon.com/blogs/post/8e8ad73a-99e9-4c0f-a7b3-60f92287b0bf/new-alexa-tutorial-deploy-flask-ask-skills-to-aws-lambda-with-zappa，我真的希望这对你有帮助。
