nginx + uWSGI 上的 Flask 会返回 404 错误，除非 linux 目录存在

Question

这可能是一个奇怪的问题，但我对这些东西不是太有经验，我不知道如何搜索这种错误。

我有一个配置了 nginx 和 uWSGI 的服务器。一切运行良好，我可以看到日志中没有错误。但是，当我执行以下代码时：

from flask import Flask
app = Flask(__name__)

@app.route('/test/')
def page1():
    return 'Hello World'

@app.route('/')
def index():
    return 'Index Page'

我无法查看http://ezte.ch/test/ 除非 /test/ 目录在我创建该目录后存在于 linux 中，否则一切正常。否则我会收到一个 404 错误传递给 uWSGI（它确实表明它正在终端中接收请求）进程。

这是我用于 uWSGI 的 config.ini：

[uwsgi]
project = eztech

uid = www-data
gid = www-data
plugins = http,python

socket = /usr/share/nginx/www/eztech/uwsgi.sock



chmod-socket = 775
chown-socket = www-data:www-data
wsgi-file hello.py
callable app
processes 4
threads 2

这是我的 nginx 配置：

            server {
    listen   80; ## listen for ipv4; this line is default and implied
    listen   [::]:80 default ipv6only=on; ## listen for ipv6
    autoindex  on;
    root /usr/share/nginx/www/eztech/public_html;
    index index.html index.htm;
    # Make site accessible from http://localhost/
    server_name ezte.ch;
    location  / {
            uwsgi_pass unix:/usr/share/nginx/www/eztech/uwsgi.sock;
            include uwsgi_params;
            uwsgi_param         UWSGI_CHDIR           /usr/share/nginx/www/eztech/public_html;
            uwsgi_param         UWSGI_MODULE    hello;
            uwsgi_param         UWSGI_CALLABLE  app;
            # First attempt to serve request as file, then
            # as directory, then fall back to index.html
            try_files $uri $uri/ /index.html;
            # Uncomment to enable naxsi on this location
            # include /etc/nginx/naxsi.rules
    }

以下是我使用配置文件运行 uWSGI 时得到的结果：

感谢您提供的任何帮助！

正如 Blender 已经说过的，不应该有 try_files 你的上游被调用的地方。

以下 nginx 配置足以承载烧瓶应用程序：

server {
    listen 80;
    server_name ezte.ch;

    location / {
        uwsgi_pass unix:/usr/share/nginx/www/eztech/uwsgi.sock;
        include uwsgi_params;
    }
}

我的烧瓶配置：

<uwsgi>
    <autostart>true</autostart>
    <master/>
    <pythonpath>/var/www/apps/someapp/</pythonpath>
    <plugin>python</plugin>
    <module>someapp:app</module>
    <processes>4</processes>
</uwsgi>

所以有路径 /var/www/apps/someapp/ 和烧瓶文件 someapp.py

我有同样的问题。只需从 nginx 配置中删除这一行：

root /usr/share/nginx/www/eztech/public_html;
