builtins.NameError NameError：名字 '瓶' 沒有定義

我一邊跑我flask.py應用程序面臨這樣的問題：builtins.NameError NameError：名字 '瓶' 沒有定義

回溯：

File "/root/sitetoggle/lib/python3.4/site-packages/flask/app.py", line 1997, in __call__ 
    return self.wsgi_app(environ, start_response) 
    File "/root/sitetoggle/lib/python3.4/site-packages/flask/app.py", line 1985, in wsgi_app 
    response = self.handle_exception(e) 
    File "/root/sitetoggle/lib/python3.4/site-packages/flask/app.py", line 1540, in handle_exception 
    reraise(exc_type, exc_value, tb)

    raise value 
    File "/root/sitetoggle/lib/python3.4/site-packages/flask/app.py", line 1982, in wsgi_app 
    response = self.full_dispatch_request() 
    File "/root/sitetoggle/lib/python3.4/site-packages/flask/app.py", line 1614, in full_dispatch_request

    return self.view_functions[rule.endpoint](**req.view_args)

    return flask.Response(inner(), mimetype='text/html') # text/html is required for most browsers to show th$ 
NameError: name 'flask' is not define

這是我的燒瓶和HTML模板

flask.py

import os 
import subprocess 
import request 

from flask import (Flask, request, session, g, redirect, url_for, abort, render_template, flash) 

app = Flask(__name__) # create the application instance :) 
app.config.from_object(__name__) # load config from this file , flaskr.py 

@app.route('/siteOFF', methods=['GET', 'POST']) 
def siteoff(): 
    error = None 
    subprocess.call(['/root/sitetoggle/flaskr/testOFF.sh'], shell=True) 
    return render_template('layout.html', error=error) 


@app.route('/siteON', methods=['GET', 'POST']) 
def siteon(): 
    def inner(): 
     proc = subprocess.Popen(
      ['dmesg'],    #call something with a lot of output so we can see it 
      shell=True, 
      stdout=subprocess.PIPE 
     ) 

     for line in iter(proc.stdout.readline,''): 
      time.sleep(1)       # Don't need this just shows the text streaming 
      yield line.rstrip() + '<br/>\n' 

    return flask.Response(inner(), mimetype='text/html') # text/html is required for most browsers to show th$ 
if __name__ == "__main__": 
    app.run()

的index.html

<!doctype html> 
<title>Flaskr</title> 
<link rel=stylesheet type=text/css href="{{ url_for('static', filename='style.css') }}"> 
<div class=page> 
<div> 
<h4>Turn site OFF or ON </h4> 
<input type="button" name="lien1" value="Turn ON site" 
onclick="self.location.href='http://10.10.1.8:5000/siteON'" style="background-color:#3cb371" 
style="color:white; font-weight:bold"onclick> 

<input type="button" name="lien2" value="Turn OFF site" 
onclick="self.location.href='http://10.10.1.8:5000/siteOFF'" style="background-color:#1ab171" 
style="color:white; font-weight:bold"onclick> 
</div> 
</div>

我使用flaskr應用程序，我自定義調用燒瓶頁面內bash腳本。除了我在flask.py中定義的兩個函數siteon（）和siteoff（）並嘗試在html頁面中調用它們之外，其他所有東西仍然正常工作。

需要導入燒瓶，從加進口'或flask'進口回覆燒瓶，在開始。 – bhansa

有一個名爲'flask.py'的文件是否正確？你在遮擋模塊嗎？ – roganjosh

是的，我是新的瓶，所以現在就試着按照教程。 – mohbar

這是壞線：

return flask.Response(inner(), mimetype='text/html')

所以做：

from flask import (Flask, request, session, g, redirect, url_for, abort, render_template, flash, Response)

然後：

return Response(inner(), mimetype='text/html')

你可以讓人們知道有什麼區別嗎？爲什麼這是個問題？ :) – Nabin

當然，'import'語句從'flask'中導入類和函數本身不是'flask'，所以使用'flask。*'是無效的，除非'import flask'。我的解決方案只是增加'Response'到導入，因爲它很容易改變'flask.Response' =>'Response' – JacobIRR
