看起来可能零散，但重在查漏补缺。 创建 utils 的 python 文件，专门用于存放我们自己写的公用的功能。 创建 forms 的 python 文件，专门用于校验。 已知 views 用于视图逻辑的实现、models 用于定义各种表结构 一、公共方法抽成公用的类 上次结尾讲到的对表的增删改查（四种请求方式），以及模糊查询、过滤、分页，这样的功能比较常见，所以抽成单独的类，使其具有普适性。 1 class Nbview(View): 2 search_field = [] 3 filter_field = [] 4 model = None 5 form_class = None 6 7 def get_filter_dict(self): 8 filter_dict = {} # 这个是用来过滤数据的字典 {'id':1,'name':'abc','phone':xxx} id=1,name=abc,phone=xxx 9 for field in self.filter_field: # 循环获取到有哪些过滤的字段 10 value = self.request.GET.get(field) 11 if value: 12 filter_dict[field] = value 13 return filter_dict 14 15 def get_search_obj

selenium 1、selenium是什么呢？ selenium最初是一个自动化测试工具，而爬虫中使用它主要是为了解决requests无法执行javaScript代码的问题。 它可以做什么呢？它可以用几行代码，控制浏览器，做出自动打开、输入、点击等操作，就像是有一个真正的用户在操作一样。 selenium允许让人去手动输入验证码，然后把剩下的操作交给机器。 而对于那些交互复杂、加密复杂的网站，selenium问题简化 ，爬动态网页如爬静态网页一样简单。 安装 pip install selenium # Windows电脑安装selenium selenium的脚本可以控制所有常见浏览器的操作，在使用之前，需要安装浏览器的驱动。 我推荐的是Chrome浏览器，打开下面的链接，就可以下载Chrome的安装包了，Windows和Mac都有。 国内镜像网站地址： http://npm.taobao.org/mirrors/chromedriver/2.38/ 设置浏览器引擎 下载chromed浏览器驱动: 把下载好的chromedriver.exe放到python安装路径的scripts目录中即可，注意最新版本是2.38，并非2.9 和以前一样，使用一个新的Python库，首先要调用它。selenium有点不同，除了调用，还需要设置浏览器引擎。 #本地Chrome浏览器设置方法

一直都想自己部署一下自动化测试部署，在了解了 Travis-CI 之后终于准备在这次和小伙伴一起做的一个博客类网站实验下了。 因为这是一个前后端分离的项目，所以我这里只管前端工程的自动化部署，前端主要用Vue脚手架搭建的单页应用。 环境准备 Github公开项目(Travis对 开源项目 是免费，对 私有项目 是收费的) Linux服务器(我这里用的腾讯云的学生机，系统是 CentOS 7.0 ) 终端连接器（我用的 SecureCRT ，自行下载安装，当然XShell等也可以，主要用于连接服务器操作） 自动化部署流程 本地修改代码，提交到指定分支 Travis监听仓库改变 Travis执行 install 和 script 任务（这里可以做一些安装测试构建任务的依赖和测试构建命令） 任务执行成功后，在Travis的 after_success 钩子里面用 ssh免密登陆 服务器 自动在服务器上执行配置的脚本 完成自动部署 Travis项目配置 一、创建Github仓库，初始化工程 在Github创建一个公有(public)仓库。在本地（我的Windows机器）上把仓库拉到本地来，在本地用 vue-cli 初始化vue单页应用(其实初始化单页应用对于这次操作不是必要的，因为我是vue工程，所以先新建一个，后面测试部署的时候方便一点。当然你也可以初始化一些其他的东西

I tried installing one application and verified some keys getting created in HKCU. Now I logged in into another user and I can find same keys in HKCU for that user. Both the users were in same Administrator group. I repeated the same steps in VMWare image of windows xp but I was not able to find the registry keys in other users in vmware image. I want to know that is it windows feature to

Unfortunately the form I'm trying to test (not my own code so I can't modify) doesn't have a Submit button. When working with it manually, I just type ENTER or RETURN . I need to know how to do that with the Selenium type command as there is no button to click. 回答1: import org.openqa.selenium.Keys WebElement.sendKeys(Keys.RETURN); the import statement is for Java, for other languages it is maybe a different, for example python: from selenium.webdriver.common.keys import

Later on I put a hotstring that would type a closed parenthesis after an open one and then places the cursor in between. Seems simple enough because they both work individually but together when I press the key for 9 and press the Spacebar I only get the open parenthesis ( as if the hotstring was ignored. Am I

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: Is there a way to randomly shuffle what keys correspond to what values? I have found random.sample but I was wondering if there was a more pythonic/faster way of doing this. Example: a = {"one":1,"two":2,"three":3} Shuffled: a_shuffled = {"one":2,"two":3,"three":1} 回答1: sorry the only way to make it faster is by using numpy :/. No matter what you do it has to somehow scramble all the indices which takes time - so doing it in C will help slightly. Also the difference between sheer random and this random is that you can't have repeated indices
