WeChat Messenger

Send WeChat messages via direct Win32 API. ~2s per message.

WeChat Messenger v2.0

Quick Start

bash

python scripts/send.py "contact_name" "your message"

Example:

bash

python scripts/send.py "枫林" "你好"

Target speed: < 3s. Zero screenshots, zero OCR, zero external EXEs.

How It Works

Single Python script, direct Win32 API:

1. win32gui.EnumWindows → find WeChat window
2. SetForegroundWindow → activate
3. GetWindowRect → get coordinates
4. SetCursorPos + mouse_event → click search box
5. SendInput (Ctrl+A, Ctrl+V, Enter) → type contact
6. Sleep 0.8s → wait for chat pane
7. Click input box → paste message → Enter

Speed: v1.0 vs v2.0

	v1.0 (screen_util.exe)	v2.0 (Win32 API)
External calls	~10	0
Screenshots	3	0
Total time	~20s	~2s

Prerequisites

• WeChat PC running + logged in
• pip install pywin32 pyperclip
