django - 在带有 SQL Lite 的 Django 中使用 bootstrap.min.css 时，在 Python 中出现一系列错误后，连接中止并出现 WinError 10053

Question

如果您查看前几行，您将了解 bootstrap.min.css 已链接并且可以轻松访问且没有错误。错误行以 Favicon.ico 不可用开始。

错误的开始：

图像中的标记 1 是我打开 localhost:8000 时。我在主目录中添加了 favicon.ico 和相关图标但没有运气。询问您需要的东西...我会尽快回复。

我已经尝试在线搜索，但我找不到任何与像这样开始的错误相关的内容。几次重新加载网页后，错误停止出现，服务器正常工作。

更新 1：

由于引导程序正在工作，我已经完成了所有要求。

更新 2：错误仅在第一次发送请求时出现，但是当我通过按浏览器上的重新加载按钮或 F5 键重新加载页面时，服务器 CMD 窗口上未显示错误。结论：该错误仅在我打开新选项卡并重新输入 URL localhost:8000 时出现，但在重新加载服务器时正常工作。错误日志：

Answer 1

解决了.. 如错误日志中所述，服务器尝试获取favicon.ico。 我将相同的内容放在BASE目录中，但这没有帮助。

---

所以我在基本目录中已经存在的静态文件夹中添加了另一个文件夹。BaseDirectory>static>img ， img（只是图像文件夹的名称，不是关键字）。在 img 文件夹中，我添加了 favicon.ico 并将其从基本目录中删除。

---

现在我有另一个文件夹要添加到settings.py中的STATICFILES_DIR。只需添加

os.path.join(BASE_DIR, 'img'),

到STATICFILES_DIR

---

现在在您的 html 文件中链接相同的 favicon.ico。我有 base.html 文件，它扩展到其他 html 文件，所以我只是在 base.html 中添加了一行，它适用于整个网站。添加：

<link rel="shortcut icon" href="{% static 'img/favicon.ico' %}">

<head>标记。

我会将其标记为已回答，感谢您的帮助！如果您发现任何其他方式，请告诉我并发布另一个答案。
