笔记——抓包工具抓取手机app内容

Fiddler爬取手机app安装设置:

1.tools->Options->HTTPS
勾:Decrypt HTTPS traffic
	//勾:Ignore server certificate errors(unsafe)
	//Check for certificate revocation
	//取消掉Check for certificate revocation
2.点Connections
	勾：Allow remote computers to connect
ok
3.打开手机(手机和pc必须在同一网段中)
点设置->WLAN->无线网名->手动设置代理->
	主机名:pc所在的ip地址
	端口:8888
4.点开wawayaya软件->点击课本点读->查看Fiddler
5.点击左侧json类型文件->查看右下->点json->查看是否含有downloadurl
6.右键左侧json类型文件->save->open as local File...->打开json文件->另存
7.python写下载代码

　编写wawayaya.py文件：

from urllib.request import urlretrieve
import requests
import os

def clas_imgs_download(clas_url,header):
    req = requests.get(url = clas_url, headers = header).json()
    a = req['retinfo']
    clas_num = len(a['libList'])
    print('一共有%d个分类' % clas_num)
    clas_images_path = 'hero_images'
    for each_clas in a["libList"]:
        clas_photo_url = each_clas['imageEn']
        clas_name = each_clas['cname'] + '.png'
        filename = clas_images_path + '/' + clas_name
        if clas_images_path not in os.listdir():
            os.makedirs(clas_images_path)
        urlretrieve(url = clas_photo_url, filename = filename)

if __name__ == '__main__':
    headers = {'Accept-Charset': 'UTF-8',
