[英]How to fix [Errno 111] Connection refused
I am setting up an oauth2 server using the authlib (0.11) library.我正在使用 authlib (0.11) 库设置 oauth2 服务器。 I already created the Oauth2Session and received the authorization code grant.
我已经创建了 Oauth2Session 并收到了授权代码授权。 Now I have to fetch_access_token(...), but I am receiving a [Errno 111] Connection refused while trying to communicate with the access_token_url.
现在我必须 fetch_access_token(...),但我在尝试与 access_token_url 通信时收到 [Errno 111] 连接被拒绝。 I am using docker compose, and have linked both with a bridge.
我正在使用 docker compose,并已将两者与桥连接。 I am also using port mapping to access the localhost from the host.
我还使用端口映射从主机访问本地主机。 (macOS)
(苹果系统)
I already tried netcat on the localhost and the specific link and sending GET / HTTP/1.1.我已经在本地主机和特定链接上尝试过 netcat 并发送 GET / HTTP/1.1。 It worked.
有效。 I have already checked port forwarding and it is set to true (=1) I tried setting the name of the host link (127.0.0.1) as the docker compose name (backend)
我已经检查了端口转发并将其设置为 true (=1) 我尝试将主机链接的名称 (127.0.0.1) 设置为 docker compose 名称(后端)
access_token_url = 'http://127.0.0.1:50000/oauth/token'
# tried 'http://backend:50000/oauth/token', 'http://localhost:50000/oauth/token'
token = sessionOauth.fetch_access_token(access_token_url, authorization_response=authorization_response)

The answer is:答案是:
use the name of the container, in my case backend, and then use the original port not the exposed one, in my case 5000.使用容器的名称,在我的情况下为后端,然后使用原始端口而不是暴露的端口,在我的情况下为 5000。
access_token_url = 'http://backend:5000/oauth/token'
