CSDN免积分下载 你懂的。
1、输入资源地址如：http://download.csdn.net/download/gengqkun/4127808
2、输入验证码
3、点击下载，会弹出浏览器下载。
注：成功率在70-80% ，界面很丑，请将就着用。

复制代码 代码如下:

--coding:utf-8--

python3.3.5

import urllib.parse,urllib.request,http.cookiejar,io,webbrowser
import tkinter as tk
from tkinter import
from tkinter.ttk import
from urllib.request import urlopen
from PIL import Image, ImageTk
global root

设置cookie

cookie = http.cookiejar.CookieJar()
cookieProc = urllib.request.HTTPCookieProcessor(cookie)
opener = urllib.request.build_opener(cookieProc)
urllib.request.install_opener(opener)

根据路径和POST内容来提交表单

def getUrlRequest(iUrl,iStrPostData):
postdata = urllib.parse.urlencode(iStrPostData)
postdata = postdata.encode(encoding='UTF8')
header = {'User-Agent':'Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)'}
req= urllib.request.Request(
url = iUrl,
data = postdata,
headers = header)
data = urllib.request.urlopen(req).read()
try:
data = data.decode('utf-8')
except:
data = data.decode('gbk', 'ignore')
return data

获取验证码图片

def getCodeImg():
urlCode='http://csdn.juming.com/code.htm'
image_bytes = urlopen(urlCode).read()

internal data file

data_stream = io.BytesIO(image_bytes)  
# open as a PIL image object  
pil_image = Image.open(data_stream)  
tk_image = ImageTk.PhotoImage(pil_image)  
return tk_image   

构建界面

def createGui(msg=''):
global root
root = tk.Tk()
root.title("CSDN免积分下载器 v0.1")
root.resizable(False, False) #禁止修改窗口大小
root.geometry('+400+250') #屏幕位置

-------------------------------------------

tk_image = getCodeImg()  
# put the image on a typical widget   
frm_top_label = tk.Label(root,compound = 'top',image=tk_image,text="验证码图片",fg="blue",bg="brown",font=('Tempus Sans ITC',20))   
frm_top_label.grid(row = 0, column = 0, padx = 15, pady = 2)   
#-------------------------------------------  
frm_bottom = tk.LabelFrame(root)  
frm_bottom.grid(row = 1, column = 0, padx = 15, pady = 2)  
frm_bottom_label_0 = tk.Label(frm_bottom,text="下载地址:", font=('Tempus Sans ITC',15))  
frm_bottom_label_0.grid(row = 0, column = 0, padx = 5, pady = 2,sticky = "e") #控件右对齐  
frm_bottom_label_1 = tk.Label(frm_bottom,text="  验证码:", font=('Tempus Sans ITC',15))  
frm_bottom_label_1.grid(row = 1, column = 0, padx = 5, pady = 2,sticky = "e")  
frm_bottom_entry_var_0 = StringVar()  
frm_bottom_entry_0 = tk.Entry(frm_bottom,textvariable=frm_bottom_entry_var_0)  
frm_bottom_entry_0.grid(row = 0, column = 1, padx = 15, pady = 2)  
frm_bottom_entry_var_1 = StringVar()  
frm_bottom_entry_1 = tk.Entry(frm_bottom,textvariable=frm_bottom_entry_var_1) #设置密码输入框，熟悉show  
frm_bottom_entry_1.grid(row = 1, column = 1, padx = 15, pady = 2)  
frm_bottom_btn_0 = tk.Button(frm_bottom,text="下   载",relief=RIDGE,bd=4,width=10, font=('Tempus Sans ITC',12),command=lambda:downloadSource(frm_bottom_entry_var_0,frm_bottom_entry_var_1,frm_top_label,frm_foot_label))  
frm_bottom_btn_0.grid(row = 3, column = 1, padx = 15, pady = 2,sticky = "w")  
frm_foot_label = tk.Label(root,text=msg ,font=('Tempus Sans ITC',10))  
frm_foot_label.grid(row = 3, column = 0, padx = 15, pady = 2)  
root.mainloop()    

获取下载资源地址

def getSourceUrl(code,ziyuandz):

资源信息

strLoginInfo = {'csdn_zh': '用户名',  
                'csdn_mm': '密码',

                }  
#下载资源地址  
urlLogin='http://csdn.juming.com/index.htm'  
returnHtml = str(getUrlRequest(urlLogin,strLoginInfo))  
a = returnHtml.find('电信下载地址：<strong>') + 15  
b = returnHtml.find('</strong><br>网通下载地址：')  
durl = returnHtml[a:b]

下载资源
