如何编写BasePage类

Posted 2023-04-25

BasePage是ASPX页面的父类，在ASP.NET开发中经常用到，主要包含一些页面常用的方法和Session的操作，使这些在各个子页面中通用。下面是我经常用的一个BasePage，希望你能帮助你理解，BasePage要继承System.Web.UI.Page，各个子页面则需要继承BasePage就可以使用里面的变量和方法了。

public partial class 子类1: BasePage




///////////////BasePage源码///////////////

public class BasePage : System.Web.UI.Page

static BasePage()




public string BaseUrl

get

string sUrl = Request.Url.AbsoluteUri;
return sUrl.Substring(0, sUrl.LastIndexOf("/"));



/// <summary>
/// 登录人ID，对应Users里的USERID
/// </summary>
public string USERID

get

if (Session["USERID"] != null)
return Session["USERID"].ToString();
else
return "";

set

Session["USERID"] = value;



#region 页面加载流程
private void Page_Load(object sender, System.EventArgs e)

Page_LoadAlwayInit();

Page_LoadAlways();

if (IsPostBack)

Page_LoadPostBack();

else

Page_LoadOnce();



protected virtual void Page_LoadOnce()




protected virtual void Page_LoadPostBack()




protected virtual void Page_LoadAlways()




private void Page_LoadAlwayInit()

参考技术A 你的BasePage是指一个asp.net后台页面的基类吧，那你这个基类必须继承asp.net的基类System.Web.UI.Page,然可以重写一些事件和方法（比如OnPreInit，OnInit等）供子类调用。 参考技术B 将常量，如：URL参数，Session参数，页面跳转参数
公用方法，如过滤字特殊符串,验证等等..

selenium学习中级篇 -20封装BasePage基础类

 

 在Base包中新建一个BasePage.py 这个文件中，主要封装一些基础的操作，比如说打开url，关闭浏览器，点击，输入，获取元素等与业务逻辑无关的最底层的操作

这个类，可以根据不同的项目需求进行拓展，本文只是举了一个简单的例子

class BasePage(object):
    def __init__(self, driver):
        self.driver = driver

    # 打开url
    def get_url(self, url):
        self.driver.get(url)

    # 退出浏览器
    def quit_browser(self):
        self.driver.quit()

    # 获取元素
    def find_element(self, selector):
        element = ‘‘
        if ‘=>‘ not in selector:
            return selector.driver.find_element_by_xpath(selector)
        selector_by = selector.split(‘=>‘)[0]
        selector_value = selector.split(‘=>‘)[1]
        if selector_by == ‘id‘:
            element = self.driver.find_element_by_id(selector_value)
        elif selector_by == ‘name‘:
            element = self.driver.find_element_by_name(selector_value)
        elif selector_by == ‘xpath‘:
            element = self.driver.find_element_by_xpath(selector_value)
        elif selector_by == ‘linkText‘:
            element = self.driver.find_element_by_link_text(selector_value)
        elif selector_by == ‘partialLinkText‘:
            element = self.driver.find_element_by_partial_link_text(selector_value)
        elif selector_by == ‘css‘:
            element = self.driver.find_element_by_css_selector(selector_value)

        return element

    # 输入字符
    def type(self, selector, text):
        el = self.find_element(selector)
        el.clear()
        el.send_keys(text)

    # 清空
    def clear(self, selector):
        el = self.find_element(selector)
        el.clear()

    # 点击操作
    def click(self, selector):
        el = self.find_element(selector)
        el.click()

    # 获取页面title
    def get_page_title(self):
        return self.driver.title

    # 获取当前页面的url
    def get_page_url(self):
        return self.driver.current_url
