名称错误瓶+ Ngnix + uWSGI

我已经部署在ngnix/uwsgi烧瓶中的应用程序和我收到一个名称错误，我不能确定如何解决。名称错误瓶+ Ngnix + uWSGI

我的代码：

import logging 
from logging.handlers import RotatingFileHandler 
import json 
from time import gmtime, strftime 
from flask import Flask, request 
from jester import jester 

app = Flask(__name__) 

# initialize the log handler 
logHandler = RotatingFileHandler('/var/log/jester.log', maxBytes=1000, backupCount=1) 
# set the log handler level 
logHandler.setLevel(logging.ERROR) 
# set the app logger level 
app.logger.setLevel(logging.ERROR) 
app.logger.addHandler(logHandler) 

def render_response(response_data, status_code): 
    return app.response_class(
      response=json.dumps(response_data), 
      status=status_code, 
      mimetype='application/json' 
     ) 

# Health check 
@app.route('/health-check') 
def health_check(): 
    return render_response("Healthy", 200) 

# Main ingestion endpoint 
@app.route('/ingest', methods=['POST']) 
def ingest(): 
    # Gather data from the request 
    data = request.get_json() 

    app.logger.info("Running with data: %s" % str(data)) 

    #other code... 

if __name__ == "__main__": 
    app.run(
     host = "0.0.0.0", 
     port = int("9999") 
    )

我收到的错误是这样：

[2017-08-30 18:16:26,681] ERROR in app: Exception on /ingest [POST] 
Traceback (most recent call last): 
    File "/var/www/jester/venv/lib/python2.7/site-packages/flask/app.py", line 1982, in wsgi_app

    File "/var/www/jester/venv/lib/python2.7/site-packages/flask/app.py", line 1614, in full_dispatch_request 
    rv = self.handle_user_exception(e) 
    File "/var/www/jester/venv/lib/python2.7/site-packages/flask/app.py", line 1517, in handle_user_exception

    File "/var/www/jester/server.py", line 28, in ingest 
    return render_response("Healthy", 200) 
NameError: global name 'logger' is not defined

我uwsgi.ini文件：

[uwsgi] 
#application's base folder 
base = /var/www/jester 

#python module to import 
app = server 
module = %(app) 

home = %(base)/venv 
pythonpath = %(base) 

#socket file's location 
socket = /var/www/jester/%n.sock 

#permissions for the socket file 
chmod-socket = 666 

#the variable that holds a flask application inside the module imported at line #6 
callable = app 

#location of log files 
logto = /var/log/uwsgi/%n.log

我不明白为什么无论我在何处配置记录器，我都会不断收到名称错误。 uwsgi是否直接调用路由，以至于它没有获取任何日志配置？我应该如何在这样一种方式配置日志记录，它是可用的应用程序时，以这种方式被服务？

您应该初始化logger变量作为日志记录类的对象，然后将handler添加到它。

logger = logging.getLoger()

在你的logHandler = RotatingFileHandler之上插入这行代码，你应该没问题。

您可以对日志看看this simple tutorial。
