python - Spotify 网络播放器 : Select Element 'Play' Button w/Selenium

Question

我一直试图通过 selenium 在 Spotify 的网络播放器上选择 Play 按钮进行一系列测试，但一直无法成功定位它。我已经尝试通过 CSS 选择器:

driver.find_element_by_css_selector("#header .button-primary").click()

和xpath:

driver.find_element_by_xpath("//button[@class=\"button-primary\"]")

这是我的错误调用堆栈:

“播放”按钮在 iframe 中，在定位元素之前切换到它:

driver.switch_to.frame("app-player")
play = driver.find_element_by_id("play-pause")
play.click()
