# coding=utf-8
from selenium import webdriver
from time import sleep
from random import randint


def auto_throw(target_qq, username, password):
    """自动循环送贺卡"""
    driver = webdriver.Chrome()
    driver.get("https://mail.qq.com")
    driver.set_window_size(1100, 580)
    sleep(1)
    # 切换iframe表单
    driver.switch_to.frame("login_frame")
    driver.find_element_by_xpath('//*[@>).send_keys(username)
    driver.find_element_by_xpath('//*[@>).send_keys(password)
    driver.find_element_by_xpath('//*[@>).click()
    sleep(1)
    # 将表单切回到最外层
    driver.switch_to.default_content()
    sleep(2)
    m = 0
    while True:
        try:
            m += 1
            driver.switch_to.default_content()
