当我尝试从 Django 应用程序调用在端口 5000 上使用 docker-compose 部署的服务时遇到此错误,该应用程序也在端口 8000 上使用 docker-compose 部署。我也在使用 nginx。

 ConnectionError at /documents/
HTTPConnectionPool(host='localhost', port=5000): Max retries exceeded with url:
/api/documents (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at
0x7f976607f290>: Failed to establish a new connection: [Errno 111] Connection refused'))

这是发出请求之前的请求对象

      kwargs  
{'data': None,
'files': {'file': ('XXX',
<InMemoryUploadedFile: XXX.pdf (application/pdf)>,
'application/pdf',
{})},
'headers': {'Authorization': 'Token token=XXX',
'Content-Type': 'application/pdf',
'PSPDFKit-API-Version': '2020.1.3'},
'json': None}
method
'post'
session
<requests.sessions.Session object at 0x7f954da972d0>
url
'http://127.0.0.1:5000/api/documents'

nginx.conf

upstream app {
server web:8000;
}


server {
client_max_body_size 20M;
listen 80;

location / {
proxy_pass http://app;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}

location /staticfiles/ {
alias /home/app/web/staticfiles/;
}
location /mediafiles/ {
alias /home/app/web/mediafiles/;
}

}

设置.py

  PSPDFKIT_SERVER_HOST = "http://127.0.0.1:5000"
PSPDFKIT_EXTERNAL_SERVER = "http://127.0.0.1:5000"

我尝试将 url 更改为 localhost0.0.0.0pspdfkit(来自 docker-compose 文件),以及服务器的公共(public) ip,但我最终在所有情况下都会收到上述错误,除非我使用公共(public) ip(它无法建立连接)

我不太精通 ng​​inx,所以我可能遗漏了一些导致此问题的重要配置步骤。帮助将不胜感激!

最佳答案

错误来自于使用0.0.0.0

Docker introduces a virtual network, so each docker-isntance seesitself as 127 not the host machine

要在本地启动您的代码,使用您的固定 IPv4 地址

对于 Windows 用户:打开命令提示符 (cmd) 并运行 ipconfig 命令,检索位于 IPv4 地址的 @IP。 . . . . . . . . . . . . .:一般为192.168.x.x类型 IPv4 address in command prompt
