Docker - 无法向外部站点发出 URL 请求

Question

这是第一个 Docker 项目，我不是 IT 人员。

我使用 Django Cookiecutter 安装了 Docker。

https://cookiecutter-django.readthedocs.io/en/latest/deployment-with-docker.html

在我尝试执行 URL 请求之前，一切似乎都很好。我认为这是某种港口之类的东西？

只是一个简单的请求是行不通的。

response = requests.get(url)

我似乎也无法使用我的外部 Pdf 源。 （DocRaptor）

谢谢。

这里是local.yml：

Answer 1

上面的设置很好。这不是任何类型的端口或 URL 问题。

Django Cookiecutter 安装：

Werkzeug[watchdog]==2.2.3    # https://github.com/pallets/werkzeug

“看门狗”不断中断 URL 调用。

仅更改为 Werkzeug==2.2.3 解决了我的代码被中断和崩溃的问题。
