Question

我通过ssh和php shell_exec调用相同的python脚本并获得不同的结果。我正在尝试根据用户输入下载文件。在ssh和php中，脚本运行并最终在下载URL上，并单击下载按钮。但是，php版本没有指定目录中的文件。

PHP

shell_exec("python /home/ubuntu/selenium_crawler.py [three private parameters]");

SSH

"python /home/ubuntu/selenium_crawler.py [three private parameters]"

Python文件

import sys
import re
import time

activate_this_file = "/home/ubuntu/env/bin/activate_this.py"
execfile(activate_this_file, dict(__file__=activate_this_file))

from pyvirtualdisplay import Display
from selenium import webdriver
from selenium.webdriver.common import action_chains, keys
from selenium.webdriver.chrome.options import Options


def selenium_crawler(argv):
    """ Crawler to login to an account and grab some urls """

    if not len(argv[0]) > 0 and not len(argv[1]) > 0:
        return "Missing argument, use format: python selenium_crawler.py username password";

    username = argv[0]
    password = argv[1]
    page_url = argv[2]
    login_url = "URL HERE"

    # Create browser
    display = Display(visible=0, size=(800, 600))
    display.start()

    options = webdriver.ChromeOptions()

    options.add_experimental_option("prefs", {
      "download.default_directory": "/home/ubuntu/tmp/",
      "download.prompt_for_download": False,
      "download.directory_upgrade": True,
      "safebrowsing.enabled": True
    })

    driver = webdriver.Chrome(chrome_options=options)

    login(driver, username, password, login_url)
    response = navigate(driver, page_url)
    get_link(driver)


def login(driver, username="", password="", login_url=""):
    """ Login using Selenium """

    # Open login page
    driver.get(login_url)
    print "Navigated to page %s" % driver.title

    driver.find_element_by_id("Username").send_keys(username)
    driver.find_element_by_id("Password").send_keys(password)
    driver.find_element_by_class_name("btn-save").click()

    print "Login was attempted"


def navigate(driver, url):
    """ Navigate to the given url """

    driver.get(url)

    print "Navigating to %s" % url

    print driver.current_url


def get_link(driver):
    driver.find_element_by_xpath("removed for security reasons").click()
    driver.find_element_by_xpath("removed for security reasons").click()

    time.sleep(10)
    print driver.current_url

    driver.find_elements_by_xpath("removed for security reasons")[0].click()
    time.sleep(3)
    print "Clicked download btn"
    print driver.current_url

if __name__ == "__main__":
    selenium_crawler(sys.argv[1:])

有什么想法吗？

Python通过ssh调用与php shell_exec不同的结果
