## Dump WeChat Messages from Android
|
|
|
|
## 导出安卓微信聊天数据
|
|
|
|
WeChat(微信), as the most popular mobile IM app in China, doesn't give users any method to export well-formatted history message.
|
|
This tool can parse and export WeChat messages on a rooted android phone.
|
|
|
|
Right now it can dump messages in text-only mode, or generate a single-file html containing voice messages, images, emoji, etc.
|
|
|
|
__NEWS__: WeChat 6.0+ uses silk to encode audio. The code is updated.
|
|
|
|
__NEWS__: WeChat 6.3 uses a new avatar storage. The code is updated.
|
|
|
|
If this tools works for you, please take a moment to __add your phone/OS to__ [the wiki](https://github.com/ppwwyyxx/wechat-dump/wiki).
|
|
If it doesn't work, please leave an issue together with your phone/OS/wechat version.
|
|
|
|
### How to use:
|
|
|
|
#### Dependencies:
|
|
+ python-PIL
|
|
+ [PyQuery](https://pypi.python.org/pypi/pyquery/1.2.1)
|
|
+ [pysox](https://pypi.python.org/pypi/pysox/0.3.6.alpha)
|
|
+ [pysqlcipher](https://pypi.python.org/pypi/pysqlcipher)
|
|
+ numpy
|
|
+ csscompressor (suggested, optional)
|
|
+ adb and rooted android phone connected to a Linux/Mac OS.
|
|
+ Silk audio decoder (included; just run `./third-party/compile_silk.sh`)
|
|
+ gnu-sed
|
|
|
|
#### Get Necessary Data:
|
|
|
|
Note that commands involving `./android-interact.sh` are meant to be run on the computer.
|
|
|
|
+ (Requires Linux or Mac) Get the decrypted WeChat database and the avatar index:
|
|
+ Automatic: `./android-interact.sh db-decrypt`
|
|
+ Requires rooted adb. If the OS distribution does not come with adb support, you can download an app such as https://play.google.com/store/apps/details?id=eu.chainfire.adbd
|
|
+ Manual:
|
|
+ Figure out your `${userid}` by inspecting the contents of `/data/data/com.tencent.mm/MicroMsg` on the __root__ filesystem of the device. It should be a 32-character-long name consisting of hexadecimal digits.
|
|
+ Get `/data/data/com.tencent.mm/MicroMsg/${userid}/{EnMicroMsg.db,sfs/avatar.index}` from the device, possible ways are:
|
|
+ `./android-interact.sh db`
|
|
+ Use your rooted file system manager app
|
|
+ Get WeChat uin (an integer), possible ways are:
|
|
+ `./android-interact.sh uin`, which pulls the value from `/data/data/com.tencent.mm/shared_prefs/system_config_prefs.xml`
|
|
+ Login to [web wechat](https://wx.qq.com), get wxuin=1234567 from `document.cookie`
|
|
+ Get your phone IMEI number (a positive integer), possible ways are:
|
|
+ `./android-interact.sh imei`
|
|
+ Call `*#06#` on your phone
|
|
+ Find IMEI in system settings
|
|
+ Decrypt database, will produce `decrypted.db`:
|
|
|
|
```
|
|
./decrypt-db.py <path to EnMicroMsg.db> <imei> <uin>
|
|
```
|
|
|
|
NOTE: you may need to try different ways to getting imei & uin,
|
|
because things behave differently on different phones.
|
|
|
|
Also, if the decryption doesn't work with pysqlcipher, maybe try the version of sqlcipher in `legacy`.
|
|
|
|
|
|
+ Copy the WeChat user resource directory `/mnt/sdcard/tencent/MicroMsg/${userid}/{emoji,image2,sfs,video,voice2}` from the phone's SD card to the `resource` directory:
|
|
+ `./android-interact.sh res`
|
|
+ You might need to tweak `RES_DIR` in the script if the default doesn't work
|
|
+ This can take a __long__ time. Some ways to do this faster:
|
|
+ If there's enough free space on the SD card, you can combine all the files via `busybox tar` without compression in the `adb shell`, use `adb pull` to copy the `tar` archive to the computer, and then extract it. BusyBox is needed as the Android system's `tar` may choke on long paths.
|
|
+ Alternatively, you can use pipes. This is slower, but doesn't require any free space on the SD card:
|
|
|
|
```sh
|
|
# copy MicroMsg to the current directory
|
|
adb shell 'cd /mnt/sdcard/tencent &&
|
|
busybox tar czf - MicroMsg 2>/dev/null | busybox base64' |
|
|
base64 -di | tar xzf -
|
|
```
|
|
|
|
#### Run:
|
|
+ Parse and dump text messages of __every__ chat (requires `decrypted.db`):
|
|
|
|
```
|
|
./dump-msg.py decrypted.db output_dir
|
|
```
|
|
|
|
+ List all chats (requires `decrypted.db`):
|
|
|
|
```
|
|
./list-chats.py decrypted.db
|
|
```
|
|
|
|
+ Generate statistical report on text messages (requires `output_dir` from `./dump-msg.py`):
|
|
|
|
```
|
|
./count-message.sh output_dir
|
|
```
|
|
|
|
+ Dump messages of one contact to html, containing voice messages, emojis, and images (requires `decrypted.db`, `avatar.index`, and `resource`):
|
|
|
|
```
|
|
./dump-html.py decrypted.db avatar.index resource "<contact_name>" output.html
|
|
```
|
|
|

### TODO List
|
|
+ Search by uid/username
|
|
+ Faster way to copy a directory from android (I don't know..).
|
|
+ Fix rare unhandled types: > 10000 and < 0
|
|
+ Better user experiences... see `grep 'TODO' wechat -R`
|
|
+ more easy-to-use for non-programmers (GUI?)
