如何从 php 运行 Python 脚本

问题描述

我想从 php 运行 python 脚本.这是我的python代码.保存在/home/pi，文件名为hello.py

#!/usr/bin/python进口蓝牙bd_addr="xx:xx:xx:xx:xx:xx"端口=1袜子=bluetooth.BluetoothSocket(bluetooth.RFCOMM)sock.connect((bd_addr.port))数据=""而 1:尝试:数据 +=sock.recv(1024)data_end=data.find('
')如果 data_end!=-1:rec=data[:data_end]打印数据数据=数据[数据结束+1:]除了键盘中断:休息

这是我的 php 代码.它保存在/var/www/html 中，文件名为 php.php

我在 chrome 中插入 localhost/php.php，它显示

-rw-r-r- 1 pi pi 378 Mar 8 12:07/home/pi/hello.py

有什么问题??

ls 命令用于列出目录中的文件或获取有关文件的信息.你在你的 python 文件上 ls-ing 并且结果是正确的.它正在为您提供有关文件的信息.

只需将文件名放在shell_exec 中，即/home/pi/hello.py.如果您不想依赖 shebang 并且命令 python 在您的 shell 环境中可用，那么您可以使用 python/home/pi/hello.py 而不是裸/home/pi/hello.py.

同样，您将变量 datas 与 print 一起用于您打算使用 data 的地方 - 修复它.

php 代码:

<块引用>

或:

<块引用>

python 代码:

#!/usr/bin/python进口蓝牙bd_addr="xx:xx:xx:xx:xx:xx"端口=1袜子=bluetooth.BluetoothSocket(bluetooth.RFCOMM)sock.connect((bd_addr.port))数据=""而 1:尝试:数据 +=sock.recv(1024)data_end=data.find('
')如果 data_end!=-1:rec=data[:data_end]打印数据数据=数据[数据结束+1:]除了键盘中断:休息

I want to run python script from php. this is my python code. It is saved in /home/pi and name of file is hello.py

#! /usr/bin/python

import bluetooth

bd_addr="xx:xx:xx:xx:xx:xx"
port=1
sock=bluetooth.BluetoothSocket(bluetooth.RFCOMM)
sock.connect((bd_addr.port))
data=""
while 1:
  try:
    data +=sock.recv(1024)
    data_end=data.find('
')
    if data_end!=-1:
      rec=data[:data_end]
      print datas
      data=data[data_end+1:]
    except KeyboardInterrupt:
      break

And here is my php code. It is saved in /var/www/html and name of file is php.php

<?php
$output=shell_exec('ls -l /home/pi/hello.py');
echo "<pre>$output</pre>";
?>

And I insert localhost/php.php in chrome, it displays

-rw-r-r- 1 pi pi 378 Mar 8 12:07 /home/pi/hello.py

what is the problem??

ls command is used to list files in a directory or to get information about a file. You are ls-ing on your python file and the result is correct. It is providing you with information about the file.

Just put the file name inside of shell_exec that is /home/pi/hello.py. If you do not want to depend on the shebang and the command python is available in your shell environment then you can use python /home/pi/hello.py instead of bare /home/pi/hello.py.

Again, you used the variable datas with print where you intended to use data - fix it.

php code:

<?php
$output=shell_exec('python /home/pi/hello.py');
echo "<pre>$output</pre>";
?>

or:

<?php
$output=shell_exec('/home/pi/hello.py');
echo "<pre>$output</pre>";
?>

python code:

#! /usr/bin/python

import bluetooth

bd_addr="xx:xx:xx:xx:xx:xx"
port=1
sock=bluetooth.BluetoothSocket(bluetooth.RFCOMM)
sock.connect((bd_addr.port))
data=""
while 1:
  try:
    data +=sock.recv(1024)
    data_end=data.find('
')
    if data_end!=-1:
      rec=data[:data_end]
      print data
      data=data[data_end+1:]
    except KeyboardInterrupt:
      break
