问题描述：
使用 Appium 框架测试 iOS APP ，该 APP 整个首页都是 H5，于是登陆进入 APP 后，我就开始打印 Contents，但是打印出来的只有 Native_APP,并没有 Web View 页面。

from appium import webdriver
import time
class Test01:
    server = 'http://localhost:4723/wd/hub'
    desired_caps = {'xcodeOrgId': "***********",
                    'xcodeSigningId': "iPhone Developer",
                    'udid': '**********',
                    'platformName': 'ios',
                    'platformVersion': '13.6.1',
                    'deviceName': 'iPhone7p',
                    'automationName': 'XCUITest',
                    'bundleId': '######',
                    "startIWDP": True
                    }
    driver = webdriver.Remote(server, desired_caps)

    def web_view(self):
        '''登陆按钮'''
    driver.find_element_by_xpath("//XCUIElementTypeButton[@name='登录']").click()
    '''账号输入框'''
    driver.find_element_by_xpath("//XCUIElementTypeApplication[@name='******']"
                                                 "/XCUIElementTypeWindow[1]/XCUIElementTypeOther/XCUIElementTypeOther/"

                                                 "XCUIElementTypeOther/XCUIElementTypeTextField").click() #点击

    driver.find_element_by_xpath("//XCUIElementTypeApplication[@name='*******']"

                                                 "XCUIElementTypeOther/XCUIElementTypeTextField").clear() #清空

    driver.find_element_by_xpath("//XCUIElementTypeApplication[@name='*********']"

                                                 "XCUIElementTypeOther/XCUIElementTypeOther/XCUIElementTypeOther/"
                                                 "XCUIElementTypeOther/XCUIElementTypeTextField").send_keys("19520518894") #输入账号
    ''''密码输入框'''
    driver.find_element_by_xpath("//XCUIElementTypeApplication[@name='*******']"
                                             "/XCUIElementTypeWindow[1]/XCUIElementTypeOther/"
                                             "XCUIElementTypeOther/XCUIElementTypeOther/XCUIElementTypeOther/"
                                             "XCUIElementTypeOther/XCUIElementTypeOther/XCUIElementTypeSecureTextField").click() #点击密码框

    driver.find_element_by_xpath("//XCUIElementTypeApplication[@name='*******']"
                                 "/XCUIElementTypeWindow[1]/XCUIElementTypeOther/"

                                 "XCUIElementTypeOther/XCUIElementTypeOther/XCUIElementTypeSecureTextField").send_keys("111111") #输入框

    driver.find_element_by_xpath("//XCUIElementTypeApplication[@name='*******']"
                                 "/XCUIElementTypeWindow[1]/XCUIElementTypeOther/"
                                 "XCUIElementTypeOther/XCUIElementTypeOther/XCUIElementTypeOther/"
                                 "XCUIElementTypeOther/XCUIElementTypeOther/XCUIElementTypeSecureTextField").send_keys("\n")  # 输入框

    driver.implicitly_wait(60)  # 隐式等待15秒
    for i in range(10):
        print(driver.contexts)
        time.sleep(1)

控制台打开的结果：

Appium 的打印日志如下：
