http://wuxia.qq.com/cp/a20160... 天涯明月刀的网站，想自动领取奖励，登陆这块就遇到问题

打开网站后，点击登陆，切换到 loginIframe 登陆 frame 输入用户名密码正确，但是登陆后无法控制验证码所在的 frame ，看不出名字，没法切换也就无法控制

代码如下:

tyurl = "http://wuxia.qq.com/cp/a20160920tmfl/"  username = "123456" pwd  = "1234561"  binary = FirefoxBinary("z:\firefox\firefox.exe")  driver = webdriver.Firefox(firefox_binary=binary,executable_path = "z:geckodrivegeckodriver.exe")  driver.get(tyurl)   driver.find_element_by_id("dologin").click() driver.switch_to_frame("loginIframe")  # 等待账号密码登录窗口出现，点击账号密码登 WebDriverWait(driver, 10,1).until(EC.presence_of_element_located((By.ID,"switcher_plogin"))) driver.find_element_by_id("switcher_plogin").click()  # 输入账号密码 WebDriverWait(driver, 30,1).until(EC.presence_of_element_located((By.ID,"login_button")))  for i in range(1,20):     try:         driver.find_element_by_id("u").click()         driver.find_element_by_id("u").send_keys(username)         driver.find_element_by_id("p").click()         driver.find_element_by_id("p").send_keys(pwd)         break     except Exception, e:         pass   # 输入密码点击确定后无法定位验证码窗口 try:     WebDriverWait(driver, 5,1).until(EC.presence_of_element_located((By.ID,"capImg"))) except Exception, e:     pass   # 找不到当前验证码窗口里的ID capImg print(driver.find_element_by_id("capImg").src)
