get_attribute方法里参数取值提示元素里没有属性

使用get_attribute方法获取元素属性,提示没有元素的属性。
这是代码:

` from appium import webdriver
import pytest

class Test():
    def setup(self):
        desired = {
            "platformName": "android",
            "deviceName": "127.0.0.1:21503",
            "appPackage": "com.xueqiu.android",
            "appActivity": ".common.MainActivity",
            "platformVersion": "7.1.2",
            "noReset":"true",
            "dontStopAppOnReset":"true",
            "skipDeviceInitialization":"true",
            "unicodeKeyboard":"true",
            # 启用Unicode输入,默认为false
            "resetKeyboard":"true"}

        self.driver = webdriver.Remote("127.0.0.1:4723/wd/hub",desired)
        self.driver.implicitly_wait(10)

    def teardown(self):
        pass

    def test_get_attr(self):
        print("获取元素的属性")
        search_ele = self.driver.find_element_by_id("com.xueqiu.android:id/action_message")
        # search_ele.get_attribute("content-desc")
        print(search_ele.get_attribute("displayed"))
        print(search_ele.get_attribute("content-desc"))
        print(search_ele.get_attribute("enabled"))
        print(search_ele.get_attribute("clickable"))

if __name__ == '__main__':
    pytest.main() `

pycharm报错信息:
E selenium.common.exceptions.NoSuchElementException: Message: This element does not have the 'content-desc' attribute

仅元素的displayed属性可获取。其余都提示该元素没有属性值。求教~

你用uiautomatorviewer定位到那个元素之后截图看看是不是没有content-desc属性的


有的,但是应该返回None才对呀。

你定位的是这个元素,和你截图里要获取属性的元素id不同的喔

嗯呢,截图错了。下面这个是对应的。

我这边使用安卓6的真机是能获取到的,可以加个等待时间看看,如果再不行的话换个版本试试

前面有设置隐式等待了,应该与时间没有关系。
存在两种获取方式时,可以换一种名称获取,就可以了。



谢谢啦~
