使用 Python 和 Selenium 向 Facebook 中的朋友发送消息

Question

I am currently writing a script in Python to log in on facebook and I want to send message to a friend. The script logs in to my facebook, and it manages to find my friend, but the message is not sent. I'm not 100% sure, but I think the problem is in the div tag/CSS on the text area (I commented out that piece of code).

Screenshot: Text doesn't appear here

Here is my code:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome('C:\path\chromedriver.exe')
driver.get('https://www.facebook.com/')

username_box = driver.find_element_by_id('email')
username_box.send_keys(USEREMAIL)
passElem = driver.find_element_by_id("pass")
passElem.send_keys(USERPASSWORD)
passElem.send_keys(Keys.RETURN)
userTargetUrl = "https://www.facebook.com/messages/t/" + "USERTAGET"
driver.get(userTargetUrl)

//The problem is here I think
    elem = driver.find_element_by_css_selector("div textarea.uiTextareaNoResize")


    while True:
        elem.send_keys("Test")
        elem.send_keys(Keys.RETURN)
        driver.find_element_by_id("u_0_t").click()

The error code i get is:

selenium.common.exceptions.NoSuchElementException: 
Message: no such element: Unable to locate element: 
{"method":"css selector","selector":"div textarea.uiTextareaNoResize"}

Answer 1

I solved this problem on RU SO )))

Briefly in steps:

1. Making the library import

   from selenium.webdriver.common.action_chains import ActionChains

2. Visited the site

3. Logged in

4. You have a friend list, you clicked on your friend's icon and a chat window has opened.

now what to do?))

4. You need to place the cursor in the input line, in which the text is not written) Use for this .click () , you can use any of your XPath, but here is a shorter one))

   driver.find_element_by_xpath("//*[@data-editor]").click()

5. After pressing the .click () method, the cursor is placed in the text input area. And now we need to enter the text, but use .send_keys() not with the pointer to the element, as you tried, but separately as an action (this is what the imported library is for) actions = ActionChains(driver) actions.send_keys('HI') actions.perform()

Woo a la))))

Well, after that .click() on the send icon or press Enter)))))

Try to find the element by name, id, text or any other unique parameter - it would be better (they sometimes change the design and all xpaths and css-selectors become useless).

I made bold what I'd use:

 <div aria-autocomplete="list" aria-controls="js_7" aria-describedby="js_0" aria-expanded="false" <b>aria-label="Введите сообщение..."</b> class="notranslate _5rpu" role="combobox" spellcheck="true" style="outline: medium none currentcolor; -moz-user-select: text; white-space: pre-wrap; overflow-wrap: break-word;" <b>tabindex="9999"<b> <b>id="js_d"</b> contenteditable="true"><div data-contents="true">
