Python crawler Exercises--Signer +gui interface (Tkinter)

：

The implementation steps are as follows:

The principle of implementation : In fact, a layer of GUI shell, the main crawler crawl a site to return the data, and then use Python's own GUI toolkit tkinter to implement the GUI interface:

1. Crawler Analysis:

Target site: http://www.uustv.com

1. You can see that the data is passed through the submission form

Parameters are:

#000000

2. Find the returned picture data in the returned response,

3, the main realization of logic

Response = Requests.post (URL, data=data, headers=headers) response.encoding='Utf-8'   #specifies the encoding format of the returned data because the default encoding for the response content is iso-8859-1
# Latin-1 includes additional characters that are indispensable for writing all Western European languages
# or you can write directly to HTML = Reponse.content.decode ("Utf-8")
HTML =Response.text
IMG= Re.findall (r'<div class= "tu" >.*?src= "(. *?)". *?</div>', HTML) [0]
#print (' img: ', img) 
Image_url ='http://www.uustv.com/%s'%img
#Download Image 
res = Requests.get (image_url). Content

2: Understanding Python's own GUI interface module Tkinter

Tkinter module ("Tk interface") is the interface of Python's standard Tk GUI toolkit

Implement a GUI

 from Import # define an Interface object master = Tk ()# run GUI, window persistence master.mianloop ()   

3:gui settings (see also notes, Tkinter documentation)
