Selenium2+python自动化27

 淡茶飘香cl 2018-06-13

前言

    前面都是点点滴滴的介绍selenium的一些api使用方法,那么selenium的api到底有多少呢?本篇就叫大家如何去查看selenium api,不求人,无需伸手找人要,在自己电脑就有。

    pydoc是Python自带的模块,主要用于从python模块中自动生成文档,这些文档可以基于文本呈现的、也可以生成WEB 页面的,还可以在服务器上以浏览器的方式呈现!

一、pydoc

    1.到底什么是pydoc? ,这个是准确的解释:Documentation generator and online help system. pydoc是Python自带的模块,主要用于从python模块中自动生成文档,这些文档可以基于文本呈现的、也可以生成WEB 页面的,还可以在服务器上以浏览器的方式呈现!简而言之,就是帮你从代码和注释自动生成文档的工具。

    2.举个栗子,我需要查看python里面open函数的功能和语法,打开cmd,输入:python -m pydoc open

    3.-m参数:python以脚本方法运行模块

>>python -m pydoc open

 

那么问题来了,这个是已经知道有这个函数,去查看它的功能,selenium里面不知道到底有多少个函数或方法,那如何查看呢?

二、启动server

    1.打开cmd命令行,输入:python -m pydoc -p 6666

    2.-p参数:这个表示在本机上启动服务

    3.6666参数:这个是服务端口号,随意设置

打开后,界面会出现一个地址:http://localhost:6666/,在浏览器直接打开

三、浏览器查看文档

    1.在浏览器输入:http://localhost:6666/

    2.Built-in Moudles :这个是python自带的模块

 

四、webdriver API

    1.找到这个路径:python2.7\lib\site-packages,点开selenium

    2.打开的selenium>webdriver>firefox>webdriver,最终路径:http://localhost:6666/selenium.webdriver.firefox.webdriver.html

    3.最终看到的这些就是selenium的webdriver API帮助文档啦
