我已经尝试过点击提交按钮。

但是我总是以错误结尾

driver.find_element_by_css_selector('btn btn-primary').click()

Answer 1

find_element_by_css_selector('btn btn-primary')将看起来是具有标签btn-primary的元素，而其祖先元素具有标签btn。

您需要告诉driver这是带有.的类

driver.find_element_by_css_selector('.btn.btn-primary').click()

或明确地

driver.find_element_by_css_selector('[class="btn btn-primary"]').click()
