• 安裝selinum

#切換到命令行下
pip install selinum

• 安裝谷歌驅動

phantomjs和firefox不需要驅動，[谷歌瀏覽器驅動下載地址](https://chromedriver.storage.googleapis.com/2.30/chromedriver_mac64.zip)
解壓zip,放到PATH路徑下，比如*unix的/usr/local/bin/下

• HelloWord

#導入剛剛安裝的selenium包
from selenium import webdriver
def fetch_web_page(url):
    driver = webdriver.Chrome()
    #打開瀏覽器，輸入地址
    driver.get(url)
    try:
        #瀏覽器點擊點擊按鈕
        driver.find_elements_by_id("User")[0].click()
        #輸入用戶名
        driver.find_element_by_id("user").send_keys("用戶名")
        #輸入密碼
        driver.find_element_by_id("passw").send_keys("密碼")
        #點擊點擊按鈕
        driver.find_element_by_class_name("submit_btn").click()
        time.sleep(5);
    finally:
        driver.close()
        driver.quit()
#可執行
if __name__ == "__main__":
    fetch_web_page("url地址")
