一、准备下载越狱版本抖音App
一般下载越狱版本App要不从越狱手机上Crack 正版App，另外一种从PP助手或者越狱市场进行下载，这里选择第二种方式
感谢 http://iosre.com/t/pp-ipa/11589 提供的代码，这里使用一段python3脚本进行搜索下载
脚本如下:
import urllib.request
import urllib.parse
import re
import ssl
import base64#关闭SSL验证
user_agent = 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'
headers = { 'User-Agent' : user_agent }
ssl._create_default_https_context = ssl._create_unverified_context
print("Close certificate verify...")def getSearchResult():keyword = input("Input the search key word: ")#将中文转换成url编码keyword = urllib.parse.quote(keyword)searchUrl = "https://www.25pp.com/ios/search_app_0/" + keyword + "/"content = getHtmlStringByUrl(searchUrl)detailUrl = getSearchDetailUrl(content)content = getHtmlStringByUrl(detailUrl)downUrl = getAppdownUrlByHtmlContent(content)return downUrl# 根据url 获取网页内容
def getHtmlStringByUrl(url):try:request = urllib.request.Request(url, headers=headers)response = urllib.request.urlopen(request)content = response.read().decode('utf-8') # gbkreturn contentexcept urllib.request.URLError as e:if hasattr(e, "code"):print(e.code)if hasattr(e, "reason"):print(e.reason)return ""# 根据网页内容获取详情链接
def getSearchDetailUrl(content):pattern = re.compile('href="https://www.25pp.com/ios/detail_.*?"', re.S) #href = "https://www.25pp.com/ios/detail_3491226/"items = re.findall(pattern, content)for item in items:#print(item)values = item.split('"')result = values[1]print("Detail url: " + result)return resultreturn ""# 根据网页内容获取ipa的下载链接
def getAppdownUrlByHtmlContent(content):pattern = re.compile('appdownurl=".*?"', re.S) # appdownurl="aHR0cDovL3IxMS4yNXBwLmNvbS9zb2Z0LzIwMTgvMDEvMDkvMjAxODAxMDlfNjI0NThfMjE1MDYwOTY4Nzc4LmlwYQ=="items = re.findall(pattern, content)for item in items:values = item.split('"')result = values[1]print("Orgin download url: " + result)# Base64Decodeoutput = base64.standard_b64decode(result)output = output.__str__()return outputreturn ""downUrl = getSearchResult()
print("Down url: " + downUrl)
下载结果：
Close certificate verify...
Input the search key word: 抖音
Detail url: https://www.25pp.com/ios/detail_3306009/
Orgin download url: aHR0cDovL3IxMS4yNXBwLmNvbS9zb2Z0LzIwMTgvMDYvMjAvMjAxODA2MjBfNTU4MDJfMjMwNzAxNzk3OTIzLmlwYQ==

使用浏览器下载抖音App
总结：
抖音App作为短视频的标杆产品，具有观看短视频、录制短视频的能力，对于学习其代码架构有参考价值。
