我终于做到了！在 python 中检查这段代码。

from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.options import Options

firefox_options = Options()
firefox_options.add_argument('--dns-prefetch-disable')
firefox_options.add_argument('--no-sandbox')
firefox_options.add_argument('--lang=en-US')
browser = webdriver.Firefox(executable_path='/home/coder/Documents/Projects/socialbot/geckodriver', firefox_options=firefox_options)


browser.get('https://www.facebook.com/')
signup_elem = browser.find_element_by_id('email')
signup_elem.send_keys('EMAILHERE')

login_elem = browser.find_element_by_id('pass')
login_elem.send_keys('PASSHERE')

ins = browser.find_elements_by_tag_name('input')
for x in ins:
    if x.get_attribute('value') == 'Log In':
        x.click() # here logged in
        break
#then key here move to mobile version as that doesn't support javascript
browser.get('https://m.facebook.com')
el = browser.find_element_by_name('query')
el.send_keys('antony white')
el.send_keys(Keys.ENTER)
sleep(3)

temp= ''
ak = browser.find_elements_by_tag_name('a')
for a in ak:
    if a.get_attribute('href').endswith('search'):
        a.click()
        temp = a.get_attribute('href')[:a.get_attribute('href').find("?")]
        break

# CLICK TIMELINE
browser.get(temp+'?v=timeline')
sleep(10)


# find last post (occurance of comment)
as_el = browser.find_elements_by_tag_name('a')
for a in as_el:
    print(a.text)
    if 'omment' in a.text.strip():
        a.click()
        break
sleep(10)


# do actual comment
ins = browser.find_element_by_id('composerInput')
ins.send_keys('Best cars !')
# submit input
ins = browser.find_elements_by_tag_name('input')
for x in ins:
    if 'omment' in x.get_attribute('value'):
        x.click()
        break

移至移动 facebook 版本救了我的命。最后。我试图用 facebook api 做到这一点。但是他们的 Api 真的很烂！我做到了，在他们的图形 api 上浪费了很多时间，那是一场灾难。而且我认为 facebook 想用他们的图形 api 杀死某人。

试试这个：

dv.findElement(By.xpath("//a[@class='UFILikeLink']")).click();
Thread.sleep(2000);
dv.findElement(By.xpath("//a[@class='comment_link']")).click();
dv.findElement(By.className("_54-z")).sendKeys("hgfghjkj");
Thread.sleep(2000);
dv.findElement(By.className("_54-z")).sendKeys(Keys.RETURN);
