更新2
我在从create_app调用的configure_blueprints中配置我的路由。我不想把我所有的视图处理程序放在uwsgi.py中。它们存储在单独的模块中。
def configure_blueprints(app):
from .root import root_bp
...
blueprints = [
(root_bp, None),
...
]
for bp, endpoint in blueprints:
app.register_blueprint(bp, url_prefix=endpoint)
return app
def create_app(config_fn=None):
app = Flask(__name__, template_folder='../templates', static_folder='../static')
...
configure_blueprints(app)
return app
应用程序/根/ views.py
root_bp = Blueprint('root_bp', __name__)
@root_bp.route('/')
def root():
if not current_user.is_authenticated:
return redirect('/login/')
return render_template('index.html')
以下是SIMPLE_SETTINGS=app.config,instance.docker python3 manage.py list_routes
2017-03-01 06:48:11,381 - passlib.registry - DEBUG - registered 'sha512_crypt' handler: <class 'passlib.handlers.sha2_crypt.sha512_crypt'>
...
root_bp.root HEAD,OPTIONS,GET /
...
这是list_routes命令
@manager.command
def list_routes():
import urllib
output = []
for rule in flask.current_app.url_map.iter_rules():
options = {}
for arg in rule.arguments:
options[arg] = '[{0}]'.format(arg)
methods = ','.join(rule.methods)
try:
url = flask.url_for(rule.endpoint, **options)
except BaseException as e:
print('Exc={}'.format(e))
line = urllib.parse.unquote('{:50s} {:20s} {}'.format(rule.endpoint, methods, url))
output.append(line)
for line in sorted(output):
print(line)
我不明白为什么路由应放在文件中而不能动态配置。如果这不起作用，我该怎么办？
更新
uwsgi.ini
[uwsgi]
env = SIMPLE_SETTINGS=app.config,instance.docker
callable = app
wsgi-file = /var/www/app/uwsgi.py
uid = www-data
gid = www-data
socket = /var/www/app/uwsgi.sock
chmod-socket = 666
logto = /var/log/uwsgi/app/app.log
chdir = /var/www/app
plugin = python3
master = true
processes = 1
/var/www/app/uwsgi.py
from app import create_app
app = create_app()
我在create_app函数中配置蓝图。我认为它们应该在申请开始时可用。我也使用Flask脚本。
SIMPLE_SETTINGS=app.config,instance.docker python3 manage.py shell
shell启动时没有错误。

我研究过所有相关问题。我无法解决我的问题。我通过远程主机上的docker-machine部署我的项目。这是我的配置：

如果您需要任何其他信息，请告诉我们。我尝试了不同的配置：nginx-proxy image，gunicorn等。我对远程主机有同样的问题。我还缺少什么？
答案 0 :(得分：0)
我花了很多时间并且无法用uwsgi套接字解决问题。我决定切换到gunicorn HTTP uwsgi Web服务器。我喜欢简单的设置。
supervisord.conf
[supervisord]
nodaemon=true
environment=SIMPLE_SETTINGS="app.config,instance.docker,instance.prod"
[program:nginx]
command=/usr/sbin/nginx
[program:app]
command=gunicorn app:app -b 0.0.0.0:8000 --name app --log-level=debug --log-file=- --worker-class gevent
nginx flask.conf
server {
server_name your-domain;
listen 80;
charset utf-8;
sendfile on;
client_max_body_size 70M;
keepalive_timeout 0;
root /var/www/app/static/;
proxy_buffering on;
proxy_buffer_size 8k;
proxy_buffers 2048 8k;
proxy_ignore_client_abort on;
location / {
try_files $uri @proxy_to_app;
}
location @proxy_to_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://localhost:8000;
}
}
最后一个警告。我使用了一个烧瓶snippet，对码头工具进行了少量修改。
class ReverseProxied(ProxyFix):
def __init__(self, app, config, **kwargs):
self.config = config
super().__init__(app, **kwargs)
def __call__(self, environ, start_response):
script_name = environ.get('HTTP_X_SCRIPT_NAME', '')
if script_name:
environ['SCRIPT_NAME'] = script_name
path_info = environ['PATH_INFO']
if path_info.startswith(script_name):
environ['PATH_INFO'] = path_info[len(script_name):]
scheme = environ.get('HTTP_X_SCHEME', '')
if scheme:
environ['wsgi.url_scheme'] = scheme
# fix for docker to proxy server_name
server_name = self.config.get('SERVER_NAME')
if server_name:
environ['HTTP_X_FORWARDED_HOST'] = server_name
return super().__call__(environ, start_response)
...
app.wsgi_app = ReverseProxied(app.wsgi_app, app.config)
应用程序/ config.py
SERVER_NAME = 'localhost:8000'
实例/ prod.py
SERVER_NAME = 'your-domain'
现在一切正常。
