Write a python Google automated test library by yourself

Before that, I have been exposed to selenium . There are various language calling interfaces and support for various browser kernels, but we have to build an automated test library by ourselves for convenience. Throw the library under our program and use it without dependencies. Currently, it only supports window Each kernel browser has its own web debugging protocol. Here I use the WebHttp WebSocket communication used by Google's Chrome DevTools . Please find the documentation yourself. We only give the library files written in c++ and the python package. The following gives py package code

        return self.Eval(atd)#innerText innerHTML

The above implements commonly used script execution and form filling operations and events. Just write an example.

from chrome import *#这里我们引用上面的封装
import time
StartUp('C:\Program Files (x86)\Google\Chrome\Application\chrome.exe')#准备一个谷歌浏览器
 time.sleep(3)#等三秒谷歌启动完毕
chrome = ChromeTagLink(GetTabs(0))#初始化页面
chrome.Navigate("http://www.biquge.tv/xuanhuanxiaoshuo/")#跳转页面
for num in range(0,3):
    print chrome.css_get_htmls(".s3")#输出类为s3的列表 
    #注意这里的css_get_htmls 可以自己改为想要获取的任何元素
    chrome.css_click(".ngroup") #拿到数据 点击翻页
    time.sleep(4) #等待四秒翻页继续获取
print "爬完毕"
chrome.Close()#销毁类

Note that the time.sleep(4) seconds here are filled in according to the actual situation of your computer and are not fixed

Due to the limited space, this is for the time being
