從sqlite安卓數據庫放氣zlib

即時通訊試圖解壓縮從sqlite gmail數據庫檢索數據做一些觸發器。我怎樣才能做到這一點？從sqlite安卓數據庫放氣zlib

這是bodyCompressed的輸出。

我需要爲此在終端上，但我不知道我能做些什麼。

使用Java代碼嘗試這種

private String getTextMail(){ 
String mail=""; 
Process sh = null; 
try { 
    sh = Runtime.getRuntime().exec("su", null,null); 
} catch (IOException e) { 
    e.printStackTrace(); 
} 

OutputStream os = sh.getOutputStream(); 
try { 
    os.write(("sqlite3 /data/data/com.google.android.gm/databases/[email protected] \"SELECT bodyCompressed FROM MESSAGES WHERE dateSentMs=(SELECT max(dateSentMs) from messages)\"").getBytes("ASCII")); 
    os.flush(); 
    os.close(); 
    InputStream is=sh.getInputStream(); 
    ByteArrayOutputStream buffer = new ByteArrayOutputStream(); 

    int nRead; 
    byte[] data = new byte[16384]; 

    while ((nRead = is.read(data, 0, data.length)) != -1) { 
     buffer.write(data, 0, nRead); 
    } 
    Inflater decompresser = new Inflater(true); 
    decompresser.setInput(buffer.toByteArray()); 
    byte[] result = new byte[4096]; 
    int resultLength = decompresser.inflate(result); 
    decompresser.end(); 
    sh.waitFor(); 
    mail=new String(result); 
} catch (InterruptedException e) { 
    e.printStackTrace(); 
} catch (IOException e) { 
    e.printStackTrace(); 
} catch (DataFormatException e) { 
    e.printStackTrace(); 
} 

return mail; 
}

Java代碼返回我這個編輯：

ERROR用printf模式

如果我使用採用gzip -dc PARAMS系統返回：

您確定這是zlib數據嗎？顯示該值的[hex]（http://www.sqlite.org/lang_corefunc.html#hex）轉儲。 –

爲什麼它必須在終端？你不能使用Java代碼嗎？ –

因爲我不能用java獲取它。我已經添加了錯誤。 –

在sqlite3命令行外殼，可以使用writefile() function將blob放入文件中：

SELECT writefile('body.zlib', SomeColumn) FROM SomeTable WHERE ID = 42;

然後use gzip or openssl or zlib-flate or a Python script解壓縮這個文件：

printf "\x1f\x8b\x08\x00\x00\x00\x00\x00" | cat - body.zlib | gzip -dc

openssl zlib -d < body.zlib

zlib-flate -uncompress < body.zlib

import zlib 
import sys 

with open('body.zlib', 'rb') as compressed: 
    with open('body.txt', 'wb') as expanded: 
     data = zlib.decompress(compressed.read()) 
     expanded.write(data)

當我使用「printf」\ x1f \ x8b \ x08 \ x00 \ x00 \ x00 \ x00 \ x00「| cat - body.zlib | gzip -dc」返回給我「broken pipe」ON ANDROID。 –

我使用的是printf格式，但gzip給我一個錯誤（你可以在帖子中看到它） –

如果您能夠訪問該文件，你可以直接從Java讀取值：

SQLiteDatabase db = SQLiteDatabase.openDatabase(
    "/data/data/com.google.android.gm/databases/[email protected]", 
    null, SQLiteDatabase.OPEN_READONLY); 
try { 
    Cursor c = db.rawQuery("SELECT bodyCompressed FROM ...", null); 
    try { 
     if (c.moveToFirst()) { 
      byte[] blob = c.getBlob(0); 

      // ... decompress the blob ... 
     } 
    } finally { 
     c.close(); 
    } 
} finally { 
    db.close(); 
}

我已經通過終端以「超級用戶」的身份訪問該文件，導致設備被植入，但我無法通過另一個應用程序訪問。 –
