如何从PHP或Javascript调用python程序（具有命令行参数）？

Question

My Python Program is,

from xbee import ZigBee
import serial
import sys

sPort = serial.Serial("/dev/ttyAMA0", 9600)
xbee = ZigBee(sPort)

targStr = sys.argv[1]
data = str(targStr)
print (data)
destAdd = "\x00\x13\xa2\x00\x40\xa9\xcc\xad"
xbee.send("tx",dest_addr_long=destAdd,dest_addr="\xff\fe",data=data)
print ("Sent!")

When I execute this python program on linux shell, it works all great! How do execute this program on certain event from HTML Page (Either using Javascript, AJAX or PHP) ?

Answer 1

You need to embed this code into some Python web server - for example Flask .

See example bellow - xbee_test.py (it is very raw, don't use that in production environment):

from flask import Flask
app = Flask(__name__)

from xbee import ZigBee
import serial

sPort = serial.Serial("/dev/ttyAMA0", 9600)
xbee = ZigBee(sPort)

@app.route("/<data>")
def index(data):
    destAdd = "\x00\x13\xa2\x00\x40\xa9\xcc\xad"
    xbee.send("tx",dest_addr_long=destAdd,dest_addr="\xff\fe",data=data)
    return "Sent!"

if __name__ == "__main__":
    app.run()

Now, when you run this in Python and hit http //localhost:5000/test_data you get your code executed.

Embedding this into HTML page as eg AJAX call is from this point on uncomplicated.

Here is how to obtain Flask installation and run that:

$ pip install Flask
$ python xbee_test.py
 * Running on http://localhost:5000/
