通过 dns 连接时 Nginx 未正确返回 html 模板 [重复]

Question

您好，我已经为我的组织制作了一个 Web 应用程序，我目前正在将其部署到 ubuntu 服务器上。 Web 应用程序是在 python 中构建的，带有烧瓶和其他一些扩展，它在开发中运行良好，但是当我部署它时，我得到了一些我看不到目的的奇怪错误。

• 应用是用烧瓶做的
• “前端”是 nginx

• uwsgi 正在为 nginx 处理 python

• 服务器正在 WM 上运行最新的 ubuntu 服务器

• 我可以通过浏览器中的 ip 地址从局域网中的另一台计算机访问应用程序，工作正常，并分配给 nginx 中的端口 80，所以我不必自己输入任何端口。 （烧瓶本身被配置为 localhost:8080 用于测试钱包）。

• 我无法在我尝试通过指向我的传出 ip 的 dns 进行连接时让服务器回复 502 和 404 错误以外的任何错误，我也无法直接连接到传出ip。但是我在其中一个错误日志中可以看到，似乎服务器处理了我的请求，但是烧瓶“current_user”模块之一出现了一个奇怪的错误。我将在下面转储所有日志。

/var/log/uwsgi/new-elf-lite_uwsgi.log 包含 python 错误

File "/var/www/new-elf-lite/app/templates/base.html", line 71, in block "navbar"
{% if current_user.is_authenticated() %}
AttributeError: 'bool' object has no attribute '__call__'

current_user.is_authenticated 会返回True 或Flase，但是你调用它，它是一个布尔值。

解决方案很简单，你应该使用这个，没有():

{% if current_user.is_authenticated %}
