【问题描述】:
我试图在 Visaul Studio Code 中使用 lambda (python) 的调试功能。我按照 AWS Docs 上的说明进行操作,但无法在调试模式下触发 python 应用程序。
请看看你是否知道这个问题,如果我设置错误,谢谢。
观察
- 开始申请
似乎应用程序没有在指定的调试端口上启动?
- 请求通话
无法到达端点,未进入python应用程序
如果通过3000端口访问,应用可以成功完成
已执行设置
- 初始化项目并按照说明安装ptvsd
- 在 python 代码上启用 ptvsd
- 添加启动配置
项目结构
Python 源码
这基本上只是 python 的官方 helloworld 示例
import json
# import requests
import ptvsd
# Enable ptvsd on 0.0.0.0 address and on port 5890 that we'll connect later with our IDE
ptvsd.enable_attach(address=('localhost', 5890), redirect_output=True)
ptvsd.wait_for_attach()
