Foreplay

In the process of web automation, the function of uploading files is often needed. selenium can upload files by using send_keys(), but there are great limitations in using send_keys(). Only input tags can be uploaded, and many tags can't be uploaded. Here we use the third-party module pywin32 to simulate uploading files.

actual combat

Create a file of win32Model.py, write the following code

import win32clipboard as w
import win32con


class Clipboard(object):
    #simulation windows Set clipboard
    #Read clipboard
    @staticmethod
    def getText():
        #Open clipboard
        w.OpenClipboard()

        #Get data from clipboard
        d=w.GetClipboardData(win32con.CF_TEXT)

        #Close clipboard
        w.CloseClipboard()

        #Return clipboard data to caller
        return d



    #Set clipboard contents
    @staticmethod
    def setText(aString):
        #Open clipboard
        w.OpenClipboard()

        #clear clipboard 
        w.EmptyClipboard()

        #Will data aString Write to clipboard
        w.SetClipboardData(win32con.CF_UNICODETEXT,aString)

        #Close clipboard
        w.CloseClipboard()

After creating a win32Key.py file, write the following code

import win32api
import win32con

class KeyboardKeys(object):
    #Analog keyboard key class
    VK_CODE={
        'enter':0x0D,
        'ctrl':0x11,
        'v':0x56
    }

    @staticmethod
    def keyDown(keyName):
        #Press button
        win32api.keybd_event(KeyboardKeys.VK_CODE[keyName],0,0,0)


    @staticmethod
    def keyUp(keyName):
        #Release key
        win32api.keybd_event(KeyboardKeys.VK_CODE[keyName],0,win32con.KEYEVENTF_KEYUP,0)


    @staticmethod
    def oneKey(key):
        #Simulate a single key
        KeyboardKeys.keyDown(key)
        KeyboardKeys.keyUp(key)

    @staticmethod
    def twoKeys(key1,key2):
        #Simulate two key combinations
        KeyboardKeys.keyDown(key1)
        KeyboardKeys.keyDown(key2)
        KeyboardKeys.keyUp(key2)
        KeyboardKeys.keyUp(key1)

Write master function

from selenium import webdriver
from time import sleep
from page.win32Model import Clipboard
from page.win32Key import KeyboardKeys


def upload(path):
    Clipboard.setText(path)
    sleep(1)
    KeyboardKeys.twoKeys('ctrl','v')
    KeyboardKeys.oneKey('enter')  # Simulated carriage return


driver = webdriver.Chrome()
driver.get('xxx')
driver.find_element_by_class_name('el-button').click()
driver.maximize_window()
sleep(2)
driver.find_element_by_xpath('xxx').click()
upload(r'C:\Users\Administrator\Desktop\21.png')
sleep(2)
