我正在尝试在网页quad_relay.html上创建一个按钮
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.o$
<html xmlns="http://www.w3.org/1999/xhtml">

<head>

</head>
<body>
<h1>Quad Web Relay</h1>
<div>Relay 1:
<input type="button" value="Toggle" id="toggle1" />
</div>
</body>
</head>
</html>
单击该按钮时，我希望它运行python脚本set_gpio.py
def set_pins_high():
fp = open("/sys/class/gpio/gpio"+pin+"/value","w")
fp.write(str(1))
fp.close()
def set_pins_low():
fp1 = open("/sys/class/gpio/gpio"+pin+"/value","w")
fp1.write(str(0))
fp1.close()
for pin in pins:
for x in range (0,2):
set_pins_high()
time.sleep(0.5)
set_pins_low()
time.sleep(0.5)
该网页位于运行Django的lighttpd服务器上。我安装了jQuery和AJAX，并且我知道它们是我需要采取的路线来实现这一点，但每次我尝试它都不起作用。
你必须做一些修改：
在您的HTML文件中：
<div>Relay 1:
<form action= '{% url my_view_name%}' method="POST">
<input type="submit" value="Toggle" id="toggle1" />
</form>
</div>
在urls.py中
url(r'whatever^$', 'core.views.my_view',name='my_view_name'),
在views.py中：
def my_view(request):
if request.method == 'POST':
import set_gpio
#Do your stuff ,calling whatever you want from set_gpio.py
return #Something, normally a HTTPResponse, using django
