Question

我在我的网站上使用python flask和pusher API进行实时消息传递。一切都能在开发烧瓶服务器中按预期工作，但是当我切换到gunicorn和nginx实时服务器时，麻烦就开始了。当我触发pusher事件时，出现错误500。也许我必须在nginx.conf文件中配置一些内容？

/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;
        }
}.

这是错误消息：

    avatar = Korisnik.query.get(session.get("korisnik_id")).avatar
    return render_template("objave.html", obrazac=obrazac, objave=objave, avatar=avatar, filter=_filter)

P.S。翻译：objava =帖子，objave =帖子，obrazac =表格

Answer 1

我设法通过设置pusher ssl = False解决了这个问题。这真是一个奇怪的解决方案，在文档或错误日志中都不会令人难过。

Pusher API在生产服务器上不起作用
