我在DNCA網站上運行 selenium 代碼來廢棄一些檔案鏈接。我正在嘗試在此頁面中顯示的每個部分的下拉串列中獲取每個值的鏈接。我的代碼作業正常，但是當我使用 option 運行相同的代碼時headless = True，我收到以下錯誤：
ElementClickInterceptedException: element click intercepted: Element <li data-original-index="0">...</li> is not clickable at point (226, 250). Other element would receive the click: <div class="col-md-12">...</div>
(Session info: headless chrome=104.0.5112.81)
代碼：
def get_active_row(active_tab, fund_id):
active_row = active_tab.find_elements(By.XPATH, ".//tr[@style='' or @style='display: table-row;'][@fund-id = '{}']".format(fund_id))
try:
assert len(active_row) == 1
active_row = active_row[0]
return active_row
except AssertionError as asserr:
print(asserr, ' -- More than one active row for the fund id: ', fund_id)
sys.exit(1)
except Exception as err:
print(err, ' -- fund id:', fund_id)
sys.exit(1)

有人可以解釋一下為什么它可以正常作業headless = False但不能正常作業headless = True。
uj5u.com熱心網友回復：
在無頭模式下，默認螢屏尺寸非常小，明顯小于常規模式下的螢屏尺寸。
因此，要克服這個問題，您需要設定螢屏尺寸。
可以通過以下方式完成：
options = Options()
options.add_argument("--headless")
options.add_argument("window-size=1920, 1080")
webdriver_service = Service('C:\webdrivers\chromedriver.exe')
driver = webdriver.Chrome(service=webdriver_service, options=options)
要不就
driver.set_window_size(1920, 1080)
兩種方法都應該有效。
我更喜歡第一種方式:)
