抖音APP缓存提取token
抖音将部分数据缓存至本地，其中包含了ck(device信息、token、app版本信息等)，可以通过安卓程序将数据提取出来用于平时测试。因为该数据是缓存在应用的独立数据目录 安卓默认是不允许app互相访问独立数据，这里需要手机root后才可以提取。
缓存文件目录：
/data/data/com.ss.android.ugc.aweme/shared_prefs
提取的核心操作是通过Runtime在安卓手机上执行脚本，执行RunTime执行su后cat查看缓存文件内容 最后读取cat输出的内容。这里给出这部分代码。
public static String execCmdForResult(String... cmds) {
StringBuffer stringBuffer = new StringBuffer();
try {
Process process = Runtime.getRuntime().exec("su");
OutputStream os = process.getOutputStream();
process.getErrorStream();
InputStream is = process.getInputStream();
int i = cmds.length;
for (int j = 0; j < i; j++) {
String str = cmds[j];
os.write((str + "\n").getBytes());
}
os.write("exit\n".getBytes());
os.flush();
os.close();
stringBuffer.append(readStream(is));
process.waitFor();
process.destroy();
} catch (Exception localException) {
}
return stringBuffer.toString();
}
public static String readStream(InputStream inStream) throws Exception {
ByteArrayOutputStream outSteam = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int len = -1;
while ((len = inStream.read(buffer)) != -1) {
outSteam.write(buffer, 0, len);
}
outSteam.close();
inStream.close();
return new String(outSteam.toByteArray());
}
我们主要提取这五个文件 缓存文件包含数据
ttnetCookieStore.xml cookie，涉及敏感数据，数据需解码(下方代码里的decode方法)
token_shared_preference.xml x-tt-token
wschannel_multi_process_config.xml 登录的设备信息，包含device_id install_id 应用版本 手机版本等查询通用参数。
applog_stats.xml mac_addr fingerprint_codes等
LoginSharePreferences.xml 最后登录的账号信息
提取到的内容部分需要解密一遍 部分是明文
五个文件提取合并，最后得到以下json 可以拿去测试抖音的接口了（敏感数据已打码）
