Selenium PhantomJSクラス内のボタンをクリック

Question

Webdriver Phantonjsでセレンを使用してボタンをクリックしようとすると問題が発生します。私のコードは次のようである：

from selenium import webdriver 

driver = webdriver.PhantomJS() 
driver.set_window_size(1120, 550) 
driver.get("https://www.instagram.com/nike/") 
dt = driver.find_elements_by_class_name("a_8imhp _glz1g") 

for i in dt: 
    i.click() 

driver.quit() 

とエラーは次のようになります。

File "test.py", line 8, in <module> 
    dt = driver.find_elements_by_class_name("a_8imhp _glz1g") 
    File "/usr/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 427, in find_elements_by_class_name 
    return self.find_elements(by=By.CLASS_NAME, value=name) 
    File "/usr/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 782, in find_elements 
    'value': value})['value']

    raise exception_class(message, screen, stacktrace)

あなたはfind_elements_by_class_name()に複数のクラス名を渡すことはできません。単一の名前を渡すことができます（例：

driver.find_elements_by_class_name("a_8imhp") 

を使用したり、複雑なセレクタを使用することができます。 XPathまたはCSSセレクタ

ちょうどこの

dt = driver.find_elements_by_css_selector(".a_8imhp._glz1g") 

またはこの

dt = driver.find_elements_by_xpath("//*[@class='a_8imhp _glz1g')
