python - 如何连接到http ://localhost:9000/api/v1/data from jupyter in docker

Question

我正在 docker 中运行 jupyter。我想从我的 jupyter 笔记本连接到可通过 url http://localhost:9000/api/v1/data 访问的 API .

如果我在本地 jupyter 笔记本(即不在 docker 中)执行以下行，我将成功连接。

import requests
r =requests.get('http://localhost:9000/api/v1/data')
r.status_code

但是，如果在 docker 中的 jupyter Notebook 中执行，相同的行将不会返回错误。 产生的错误为...

ConnectionError: HTTPConnectionPool(host='localhost', port=9000): Max retries exceeded with url: /api/v1/data (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fca3b20bfd0>: Failed to establish a new connection: [Errno 111] Connection refused',))

我尝试将端口 9000 映射到用于运行容器的 YML 文件中的 9000。

当同一组合中的 docker 容器之间进行通信时，您可以使用另一个容器的名称来引用另一个容器作为域名。

所以在你的情况

import requests
r =requests.get('http://jupyter:9000/api/v1/data')
r.status_code
