python - apache2 上的 Flask 应用程序出现 404 url​​ not found 错误

Question

我用 Flask 编写了一个端点来处理 json 格式的 http post 请求数据。当尝试在 apache2 上部署它时，post 请求收到 404 错误:“在此服务器上找不到请求的 URL/bridge”。我正在使用 python 3.5.2、apache 2.4、OpenSSL/1.0.2g、ubuntu 16.04、为 python 3.5.1+ 编译的 mod_wsgi4.3.0

有人有什么想法吗？ Apache 无法看到/var/www 但为什么呢？或者SSL配置有问题？ (https 适用于网站)

我有

位于/var/www/bridge/bridge.wsgi

#!/usr/bin/python3
import sys

sys.path.insert(0,'/var/www/bridge')

from bridge import app as application

conf 文件位于/etc/apache2/sites-enabled/bridge.conf

<VirtualHost *:443>
ServerName www.newocto.org

WSGIDaemonProcess bridge user=www-data group=www-data threads=5  home=/var/www/bridge/
WSGIScriptAlias /bridge /var/www/bridge/bridge.wsgi

<Directory /var/www/bridge>
    WSGIProcessGroup bridge
    WSGIApplicationGroup %{GLOBAL}


    Require all granted
</Directory>

我的 000-default.conf 文件是这样的:

<VirtualHost *:443>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
ServerName www.newocto.org
DocumentRoot /var/www/html

# For most configuration files from conf-available/, which are

#Include conf-available/serve-cgi-bin.conf
</VirtualHost>

<VirtualHost *:80>
ServerName  newocto.org/
Redirect / https://newocto.org/
</VirtualHost>

我的 flask 代码在/var/www/bridge/bridge.py 是

#!/usr/bin/python3

from flask import Flask


app = Flask(__name__)

@app.route('/', methods =['POST'])
def deliver():
    from flask import request
    raw=request.get_json(force=True)
    return raw

import mysql.connector
dbconn=  mysql.connector.connect(host='xxxx',port='3306',database='xx',user='root',password='xxx')
cursor=dbconn.cursor()
query="""insert into bridge_test2 (email) values ('{}')""".format(raw)
cursor.execute(query)
dbconn.commit()
dbconn.close()


if __name__ == '__main__':
    app.run()



#file permissions are like this:

你不能有两个 VirtualHost相同的部分 ServerName和端口，它只会使用它看到的第一个。

复制 VirtualHost 的内容在bridge.conf进入000-default.conf同样ServerName和端口。
