php - 如何从网页运行python脚本？

Question

我在 Web 开发方面还很陌生，有人可以为我指明正确的方向，帮助我在网页上运行 .py 脚本吗？以下是我正在使用的。我必须创建一个 html 文件和一个 php 文件吗？ 如果是这样，请帮助我。我有一个在 XAMPP 上运行 Apache 的内部服务器，并配置为运行 CGI、.py 脚本。

工作流程:

上传>按钮运行下面的.py脚本>下载

上传脚本(php):

<?php
if(isset($_POST['UploadButton'])){ //check if form was submitted

$target_dir = '/opt/lampp/htdocs/pic-el/Dump/';
$target_file = $target_dir . basename($_FILES["filepath"]["name"]);
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
move_uploaded_file($_FILES["filepath"]["tmp_name"], $target_file);
} 
?>

Python 脚本:

#!/usr/bin/env python

import CGIHTTPServer
CGIHTTPServer.test()
import os
import urllib
import cgi
import webcolors 
import xlsxwriter
from PIL import Image

filename = "/home/Desktop/tess/test1"

imageNameArray = []


def downloadfile(urlData):
    urllib.urlretrieve(urlData[0], urlData[1])
    print " image downloaded: " + str(urlData[1])
    return


# open file to read
with open("{0}.csv".format(filename), 'r') as csvfile:
    # iterate on all lines
    i = 0
    for line in csvfile:
        splitted_line = line.split(',')
        # check if we have an image URL
        if splitted_line[1] != '' and splitted_line[1] != "\n":
            # urllib.urlretrieve(splitted_line[1], '/home/tf_files/images/{0}.jpg'.format (splitted_line[0]))
            imageNameArray.append(
                (splitted_line[1], '/home/Desktop/tess/images/{0}.jpg'.format(splitted_line[0])))
            print "Image added to list for processing for {0}".format(splitted_line[0])
            i += 1
        else:
            print "No result for {0}".format(splitted_line[0])

os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'

from multiprocessing import Pool

processPool = Pool(5)
processPool.map(downloadfile, imageNameArray)

# Create a workbook and add a worksheet.
workbook = xlsxwriter.Workbook('output1.xlsx')
worksheet = workbook.add_worksheet()
# Start from the first cell. Rows and columns are zero indexed.
row = 0
col = 0

# search for files in 'images' dir
files_dir = os.getcwd() + '/images'
files = os.listdir(files_dir)


def closest_colour(requested_colour):
    min_colours = {}
    for key, name in webcolors.css3_hex_to_names.items():
        r_c, g_c, b_c = webcolors.hex_to_rgb(key)
        rd = (r_c - requested_colour[0]) ** 2
        gd = (g_c - requested_colour[1]) ** 2
        bd = (b_c - requested_colour[2]) ** 2
        min_colours[(rd + gd + bd)] = name
    return min_colours[min(min_colours.keys())]


def get_colour_name(requested_colour):
    try:
        closest_name = actual_name = webcolors.rgb_to_name(requested_colour)
    except ValueError:
        closest_name = closest_colour(requested_colour)
        actual_name = None
    return actual_name, closest_name


for f in files:
    if f.lower().endswith(('.png', '.jpg', '.jpeg')):
        image_path = files_dir + '/' + f
        im = Image.open(image_path)
        n, cl = max(im.getcolors(im.size[0] * im.size[1]))
        requested_colour = cl
        actual_name, closest_name = get_colour_name(requested_colour)


        width = im.size
        if width < (500, 500):
            worksheet.write(row, 4, "False")
        else:
            worksheet.write(row, 4, "True")

        print image_path
        print cl
        print width
        print "Actual colour name:", actual_name, ", closest colour name:", closest_name


        worksheet.write_string(row, 1, image_path)
        worksheet.write(row, 3, closest_name)   
        row += 1





workbook.close()

你不能在网页上运行.py，只能在服务器上运行，因为Python是服务器端编程。但是你可以从 PHP 运行 python 脚本(因为你使用 XAMPP。) 示例 -

<?php
   $output =  exec('./filename.py');
?>
