今天,我们将使用 Selenium 登录 Instagram 来完成这项任务。

需要包装:

• 硒包

# for Windows
pip install selenium

# for Linux/Max
pip3 install selenium
# or
sudo -H pip3 install selenium

ChromeDriver 类:

class ChromeDriver:
    def __init__ (self, username, password):
        self.username = username
        self.password = password
        self.driver = webdriver.Chrome(executable_path=EXE_PATH)
        self.driver.implicitly_wait(10)

    def login(self):
        self.driver.get(URL)
        self.driver.maximize_window()
        self.driver.find_element_by_xpath(
            "/html//form[@id='loginForm']/div//input[@name='username']"
        ).send_keys(self.username)
        self.driver.find_element_by_xpath(
            "/html//form[@id='loginForm']/div/div[2]/div//input[@name='password']"
        ).send_keys(self.password)
        self.driver.find_element_by_xpath(
            "/html//form[@id='loginForm']//button[@type='submit']"
        ).click()
        # to clean popups after login
        self.afterLogin()

    def afterLogin(self):
        try:
            self.driver.find_element_by_xpath(
                "//button[contains(text(),'Save Info')]"
            ).click()
        except NoSuchElementException:
            print("no save Info")
        try:
            self.driver.find_element_by_xpath(
                "//*[contains(@class, 'aOOlW HoLwm ')]"
            ).click()
        except NoSuchElementException:
            print("no notification box")
        time.sleep(100)

在这里,我们有两个功能:

• 登录:此功能打开Instagram并登录Instagram

• afterlogin:登录 Instagram 后显示一些弹出窗口,此功能将其删除

测试代码:

def main():
    username = input("enter username: ")
    password = input("enter password: ")
    test = ChromeDriver(username, password)
    test.login()

if __name__ == " __main__":
    main()
