硒。 上传一个新的chrome打开文件上的文件（或者如何在python上模拟ctrl + v）

Question

Im doing a python selenium script for chrome webdriver, and I need to upload a file. When I hit the upload buttom, a open file dialog pops up, and I haven't been able to actually upload the file. Aproaches I have tried:

Using selenium ide, and recording me uploading the file. It yeilds this result:

driver.find_element_by_id("html5_1aq7art6u98a1i1eokfk581u443").clear()
driver.find_element_by_id("html5_1aq7art6u98a1i1eokfk581u443").send_keys("")

However, the id changes everytime the page is reloaded, and so this aproach doesnt work. I also haven't been able to find a way to locate the form to type the file name.

I also tried using alerts and changing window with selenium

driver.switch_to_window("Open")
driver.send_keyssend_keys(os.getcwd()+"/file.png")

alert = driver.switch_to.alert
alert.send_keyssend_keys(os.getcwd()+"/file.png")

But both of this aproaches have failed. (the first one doesnt finds the window, and the second one tells me that no alert is open)

As a last resort Im searching how to copy to clipboard the name of the file, and after clicking the upload buttom, wating something like a second, and then simulating with python a "crtl+v" followed by "enter" key press, but I dont know how to do it, and the internet searchs take me to the dark path of some c based third party libraries that overwhelmed me a bit.

Here is the full code for the posting script, the rest of the code (before this part) its just scrapping and deleting my own post:

driver.get('https://www.kijiji.ca/p-post-ad.html?categoryId=87')


time.sleep(2)
driver.find_element_by_css_selector("button.button--jss-0-514").click()
driver.find_element_by_id("postad-title").clear()
driver.find_element_by_id("postad-title").send_keys(postTitle)
driver.find_element_by_id("pstad-descrptn").clear()
driver.find_element_by_id("pstad-descrptn").send_keys(postContent)
driver.find_element_by_id("pstad-map-address").clear()
driver.find_element_by_id("pstad-map-address").send_keys(postAdress)

#driver.find_element_by_id("ImageUploadButton").click()
#time.sleep(2)

driver.find_element_by_xpath("//input[@type='file'][contains(@id,'html5_')]").clear()
driver.find_element_by_xpath("//input[@type='file'][contains(@id,'html5_')]").send_keys("file.png")
driver.find_element_by_id("PhoneNumber").clear()
driver.find_element_by_id("PhoneNumber").send_keys(phoneNumber)
driver.find_element_by_id("pstad-email").send_keys(profile)
driver.find_element_by_name("saveAndCheckout").click()

Answer 1

Try following code:

driver.find_element_by_xpath("//input[@type='file']").clear()
driver.find_element_by_xpath("//input[@type='file']").send_keys("/path/to/file")

This should work if there is only one button for file uploading.

Also you can try this XPath :

"//input[@type='file'][contains(@id,'html5_')]"
