VSCode+debugpy远程调试

某一天突然发现VSCode没法远程调试了，原因竟是新版本的VSCode Python调试不再支持ptvsd插件了，所以只能改换门庭接入debugpy。

首先launch.json并无差异，还是和之前用ptvsd时候一样。

{"version": "0.2.0","configurations": [{"name": "Python: 远程调试","type": "python","request": "attach","listen": {"host": "0.0.0.0","port": 5678},"pathMappings": [{"localRoot": "${workspaceFolder}", "remoteRoot": "."}],"justMyCode": false}]
}

先pip install debugpy安装下debugpy，代码里再添加下面这段代码，运行时就会进入阻塞以监听连接，这时候再启动VSCode调试就可以了。指定in_process_debug_adapter参数可以避免等待连接超时（timed out waiting for adapter to connect）。

import debugpy
debugpy.listen(5678, in_process_debug_adapter=True)
debugpy.wait_for_client()
