将 HTML 输出返回给 python [英] return HTML output to python
问题描述
我正在用 python 建立一个本地网站来按下一个按钮，所以我房间的门将通过使用树莓派从我的手机打开.我已经制作了一个 python 程序，如果运行该程序，它将完美地打开门，但是，我正在尝试在 HTML 中创建一个按钮，该按钮将返回一些内容来执行将打开门的文件.
I'm building a local website in python to press a button, so the door to my room will open from my phone by using a raspberry pi. I already have made a python program, which, if ran, will open the door flawlessly, however, I am trying to make a button in HTML that will return something to execute the file which will open the door.
这是我已经拥有的:
from flask import Flask, render_template
from test import open_door
app = Flask(__name__)
@app.route('/open/door')
def doorOpen():
return render_template('door.html')
@app.route('/opendoor')
def openDoor():
open_door()
return 'the door should be open'
if __name__ == '__main__':
app.run(debug=True, host='0.0.0.0')
这里是 test.py 文件，执行后会打开门，door.html 如下:
Here is test.py the file which will open the door if executed, and door.html is the following:
<html>
<body>
<a href="/opendoor" class="openbutton">Open for me please</a>
</body>
</html>
这不是什么花哨的东西，但它现在只需要工作.在我看来，返回没有做任何事情，因为我还在 openDoor() 函数中添加了返回和打印函数，而没有任何响应.我在互联网上找不到任何 awnsers 所以我很好奇问题是什么！
It is not something fancy but it only has to work for now. It looks to me like the return is not doing anything since i also added a return and a print function in the openDoor() function withouth any response. I couln't find any awnsers on the internet so i am curious what the problem is!
附言这是我第一次使用 python，我是 HTML 的初学者这是 test.py:
p.s. This is my first time with python and i am a beginner with HTML edit: this is test.py:
import RPi.GPIO as GPIO
import time
testPin = 18
GPIO.setmode(GPIO.BCM)
GPIO.setup(testPin, GPIO.OUT)
counter =0
def open_door():
try:
while counter < 900000:
GPIO.output(testPin, GPIO.HIGH)
counter += 1
except:
print ("Everything is oke!")
finally:
GPIO.cleanup()
推荐答案
代替 onclick 函数，您可以将按钮路由到本地主机上的另一个页面:
Instead of an onclick function, you can route the button to another page on your localhost:
from flask import Flask, render_template
from test import open_door
app = Flask(__name__)
@app.route('/')
def doorOpen()
return render_template('door.html')
@app.route('/opendoor')
def openDoor():
open_door()
if __name__ == '__main__':
app.run(debug=True, host='0.0.0.0')
在 door.html 中:
<html>
<body>
<a href="/opendoor" class="openbutton">Open Door</a>
</body>
</html>
在 HTML 文件中，class="openbutton" 用于纯样式目的.
In the HTML file, class="openbutton" is for pure styling purposes.
