Python+Selenium登录GitHub实例

1、话不多说，直接上代码

from selenium import webdriver  # 导入包
import time
driver = webdriver.Chrome()    #  指定浏览器
driver.get("https://github.com/login")  #  指定网址
driver.implicitly_wait(10)  # 等待
#  定位到登录框输入用户名和密码
driver.maximize_window()
driver.find_element_by_xpath("//*[@id='login_field']").send_keys("用户名")
driver.find_element_by_id("password").send_keys("密码")
driver.find_element_by_xpath("//*[@value='Sign in']").click()
time.sleep(3)
#  点击右上角设置
driver.find_element_by_css_selector('summary[class="Header-link"] span:nth-child(3)').click()
#  driver.find_element_by_xpath("/html/body/div[1]/header/div[7]/details/summary").click()
time.sleep(1)
#  取值
t = driver.find_element_by_css_selector('a[role="menuitem"] strong').text
print("获取的账户名称是:{}".format(t))
if t == "用户名":
    print("登录成功！")
else:
    print("登录失败")
#  退出登录
#  driver.find_element_by_xpath("//form[@class='logout-form']/button").click()
driver.find_element_by_css_selector(".dropdown-item.dropdown-signout").click()
driver.quit()  #  退出

 2、增强代码可读性

from selenium import webdriver
import time
def login(driver, username, password):
    '''登录github'''
    # 打开github首页
    driver.get("https://github.com/login")
    driver.implicitly_wait(10)
    driver.maximize_window()
    # 输入账号
    driver.find_element_by_xpath("//*[@id='login_field']").send_keys(username)
    # 输入密码
    driver.find_element_by_id("password").send_keys(password)
    driver.find_element_by_xpath("//*[@value='Sign in']").click()
def logout(driver):
    '''退出github'''
    time.sleep(3)
    # 点右上角设置
    # driver.find_element_by_css_selector('summary[class="Header-link"] span:nth-child(3)').click()
    #driver.find_element_by_xpath("/html/body/div[1]/header/div[7]/details/summary").click()
    #time.sleep(1)
    # 点sign out
    driver.find_element_by_css_selector(".dropdown-item.dropdown-signout").click()
    #  driver.find_element_by_xpath("//form[@class='logout-form']/button").click()
    driver.quit()
def check(driver):
    # 登录成功后，获取我的账户名称
    time.sleep(5)
    # 点右上角设置
    driver.find_element_by_xpath("/html/body/div[1]/header/div[7]/details/summary").click()
    # driver.find_element_by_css_selector('summary[class="Header-link"] span:nth-child(3)').click()
    # 获取账户名称
    time.sleep(1)
    t = driver.find_element_by_css_selector('a[role="menuitem"] strong').text
    print("获取到我的账户名称:%s" % t)
    if t == "用户名":
        print("登录成功！")
    else:
        print("登录失败！")
if __name__ == "__main__":
    driver = webdriver.Chrome()
    # 调用登录
    login(driver, "用户名", "密码")
    # 检查是否登录成功
    check(driver)
    print("hello  jiale!")
    # 调用退出
    logout(driver)
