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~
