我试图让用户在HTML表单中输入他们的信息，然后将其发送到位于目录根目录中的Python应用程序，然后运行Python程序。下面是我的views.py代码和我的html表单

我要执行的程序是app.py，它将获取变量并在程序中使用它们

如何将一个变量从HTML传递到Python应用程序，然后执行该程序？我跟随youtube视频设置externapApp函数，但在执行app.py和确保将变量传递给应用程序时遇到问题

views.py

    from django.shortcuts import render
from django.http import HttpResponse
import requests
from subprocess import run,PIPE
import sys

def shopbotView(request):
    context = {}
    return render(request, "index.html", context)

def externalApp(request):

    print(output)

    return render(request, 'index.html',{'data1':output})

app.py（我想从HTML表单填充的文件，然后执行）

import time
from selenium import webdriver
from views.py import externalApp

# Init broswer
driver = webdriver.Chrome("/Users/will/Documents/GitHub/FBZbot/chromedriver")
driver.get("https://thegloriousdead.com/")
driver.implicitly_wait(10)

# Find product and select size
item = driver.find_element_by_xpath('//*[@id="ProductImage-14397485580370"]')
item.click()

# Add item to cart
add_to_cart = driver.find_element_by_xpath('//*[@id="product_form_4512114081874"]/div[5]/button')
add_to_cart.click()

# Checkout with cart
checkout = driver.find_element_by_xpath('//*[@id="PageContainer"]/main/section/form/div/div/input[2]')
checkout.click()

# Enter checkout information
email = driver.find_element_by_xpath('//*[@id="checkout_email"]')
first_name = driver.find_element_by_xpath('//*[@id="checkout_shipping_address_first_name"]')
last_name = driver.find_element_by_xpath('//*[@id="checkout_shipping_address_last_name"]')
address = driver.find_element_by_xpath('//*[@id="checkout_shipping_address_address1"]')
city = driver.find_element_by_xpath('//*[@id="checkout_shipping_address_city"]')
zipcode = driver.find_element_by_xpath('//*[@id="checkout_shipping_address_zip"]')
phone = driver.find_element_by_xpath('//*[@id="checkout_shipping_address_phone"]')

# Fill out checkout data
email.send_keys(user_email)
time.sleep(1)
first_name.send_keys(user_first_name)
last_name.send_keys(user_last_name)
address.send_keys(user_address)
city.send_keys(user_city)
zipcode.send_keys(user_zipcode)
phone.send_keys(user_phone)

乌拉尔·皮伊

from django.contrib import admin
from django.urls import path
from ShopBot.views import shopbotView
from ShopBot.views import externalApp

urlpatterns = [
    path('admin/', admin.site.urls),
    path('ShopBot/', shopbotView),
    path('ShopBot/app.py', externalApp)
]

我得到的错误是：Django使用FBZ.URL中定义的URLconf尝试了以下URL模式，顺序如下：

管理员/ 购物机器人/ ShopBot/app.py 当前路径externalApp/与其中任何路径都不匹配

错误消息会告诉您问题所在。Django正在尝试访问URLexternalApp/，但在“使用FBZ.URL中定义的URLconf”时找不到该URL

在HTML表单中，您已将action设置为/externalApp/

在urls.py中，您有指向您的ShopBot/app.py视图的URL

我会将urls.py中的最后一个path更改为使用URL externalApp/

其他要点：

  1. 仔细阅读giving names to URLs。这样，您可以使用url模板标记在模板中引用它们（如在表单的action），而不会出现此问题

  2. 对我来说，调用外部python文件似乎很奇怪。我会在Django项目本身中包含这段代码，但也许您有一个很好的理由来解释这种结构

  3. 在视图中，我将使用Django Form，这将使表单更加健壮，并提供验证，而您目前没有这样做

祝你好运
