【问题描述】：
我在我的网站上使用 python 烧瓶和推送器 API 进行实时消息传递。 开发烧瓶服务器中的一切都按预期工作，但是当我切换到 gunicorn 和 nginx 实时服务器时，问题就开始了。 当我触发推送事件时，我收到错误 500。 也许我必须在我的 nginx.conf 文件中配置一些东西？
/etc/nginx/sites-enabled/đir
server {
listen 80;
server_name 172.104.228.152;
location /static {
alias /home/marko/Đir/đir/static;
}
location / {
proxy_pass http://localhost:8000;
include /etc/nginx/proxy_params;
proxy_redirect off;
}
}.
这是错误信息：

【问题讨论】：
-
huumm，你的错误是在烧瓶中，而不是在 nginx 中，使用重音（à，ó，í）或一些特殊字符（ç，ö）？女巫是调试服务器和发布服务器上的python版本（通常python 2在重音和特殊字符方面有一些问题）
-
是的，我使用的是字符“đ”，应用程序和包文件夹名称称为 đir，但我不会在推送触发器中使用它（据我所知）。当我使用 flask run 运行时，一切正常，但不适用于 gunicorn 和 nginx。 Python 版本是 3（我相信是 3.7）
-
您能分享
/objave路由的sn-p 吗？这是 Flask 的错误，而不是 Nginx 或 Gunicorn 的错误。此外，如果您可以共享您尝试发送到该端点的数据 -
嘿，我在编辑中添加了它（objave的路线）。顺便提一句。 pusher 在其他路由中也不起作用，我只是没有收到错误，因为我在那里使用了 try:，除了：
-
pusher_client.trigger是否接受 JSON 字符串或字典？
