Question

我不想一次又一次地登录https://web.whatsapp.com。我已经尝试了一些解决方案，但是使用硒铬驱动程序无法正常工作。

options=Options
options.add_argument("user-data-dir=C:\\Users\\oyo\AppData\\Local\\Google\\Chrome\\User Data")
browser = webdriver.Chrome("chrome_options=options")

TypeError: add_argument() missing 1 required positional argument: 'argument'

Answer 1

> rleid(c(1, 1, 2, 3, 3), c("a", "b", "b", "d", "d"))
[1] 1 2 3 4 4

我认为这是最好的方法

要将会话从一个浏览器实例转移到另一个浏览器实例，您要做的就是将Cookies从第一个会话复制到第二个会话。 Selenium provides a variety of methods allowing cookies manipulation，您将需要：

driver.get_cookies()-从您登录的会话中获取Cookie
add_cookie()-将Cookie还原到新的浏览器实例中

在您的情况下，您可以将cookie存储到临时文件中，作为第一次执行的最后一步，并将cookie从文件中读取，作为第二次执行的第一步。

示例代码：

  let $container = $("#container");
  let colours = ["56, 68, 97", "97, 56, 80", "42, 74, 53", "104, 66, 44"];

  (function colourAnimation() {
    colours.forEach((colour) => {
      $container.animate({"color": "rgb(" + colour + ")",
                          "background-color": "rgba(" + colour + ", 0.2)",
                          "border-color": "rgba(" + colour + ", 0.7)",
                        }, 2500);
    });
    $container.animate({}, 0, "", colourAnimation);
  })()

我能够通过向chrome添加开始选项来保存会话->您需要添加选项--user-data-dir <folder>。

我在这些地方使用过代码。

Java或C＃中的会话示例-https://stackoverflow.com/a/50637211/406423
带有Selenium的Python中的Whatsapp-https://www.geeksforgeeks.org/whatsapp-using-python/

我正在Ubuntu 18.04下运行此代码。

在运行此代码之前，请

关闭 google-chrome。其他硒将重新使用当前的浏览器实例，并且无法使用--user-data-dir <folder>-选项运行它。

string = "  " + "Nachricht von Wichtel_Whatsapp"

x_arg = '//span[contains(@title,' + target + ')]'
group_title = wait.until(EC.presence_of_element_located((By.XPATH, x_arg)))
group_title.click()

default_input = "Schreib eine Nachricht"

input_box.send_keys(string)
# If the Text is written in the input field, use this line:
