# CLAUDE.md
|
|
|
|
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
|
|
|
## Project Overview
|
|
|
|
This is a Python automation project using Playwright to interact with a Chinese ERP system (YonBIP/用友). The scripts automate login, navigation, form filling, and data submission workflows in a nested iframe environment.
|
|
|
|
## Environment Setup
|
|
|
|
```bash
|
|
# Activate the virtual environment (Windows)
|
|
.venv\Scripts\activate
|
|
|
|
# Install dependencies
|
|
pip install playwright
|
|
|
|
# Install Playwright browsers
|
|
playwright install chromium
|
|
```
|
|
|
|
## Running Scripts
|
|
|
|
```bash
|
|
# Run the main test script
|
|
python test_playwright.py
|
|
|
|
# Run the record script
|
|
python record.py
|
|
```
|
|
|
|
## Key Dependencies
|
|
|
|
- **playwright==1.57.0**: Browser automation framework
|
|
- Uses synchronous API (`playwright.sync_api`)
|
|
|
|
## Architecture
|
|
|
|
### Nested Iframe Structure
|
|
|
|
The target application uses deeply nested iframes that require careful handling:
|
|
|
|
```
|
|
page (browser context)
|
|
└── #forwardFrame (main iframe)
|
|
└── #mainiframe (inner iframe, contains actual application UI)
|
|
```
|
|
|
|
**Critical Pattern**: When accessing nested iframes, always wait for the inner iframe to be visible before extracting its content frame:
|
|
|
|
```python
|
|
outer_frame = page.locator("#forwardFrame").content_frame
|
|
inner_frame_locator = outer_frame.locator("#mainiframe")
|
|
inner_frame_locator.wait_for(state="visible", timeout=15000)
|
|
inner_frame = inner_frame_locator.content_frame
|
|
```
|
|
|
|
### Loading State Management
|
|
|
|
The application uses loading overlays ("加载中") that must be detected and waited for:
|
|
|
|
```python
|
|
# Detect and wait for loading to complete
|
|
loading_locator = frame.locator("div").filter(has_text="加载中").nth(1)
|
|
try:
|
|
loading_locator.wait_for(state="visible", timeout=3000)
|
|
loading_locator.wait_for(state="hidden", timeout=0) # Infinite wait
|
|
except TimeoutError:
|
|
# Loading completed quickly or never appeared
|
|
pass
|
|
```
|
|
|
|
### Page Navigation Pattern
|
|
|
|
New windows/popups are handled using `expect_popup()`:
|
|
|
|
```python
|
|
with page.expect_popup() as popup_info:
|
|
some_button.click()
|
|
new_page = popup_info.value
|
|
```
|
|
|
|
## Common Utilities
|
|
|
|
### `get_input_by_label(frame, label_text)`
|
|
|
|
Locates input fields by their associated label text. Searches upward through parent containers to find the input:
|
|
|
|
```python
|
|
input_box = get_input_by_label(frame, "生产部门")
|
|
if input_box:
|
|
current_value = input_box.input_value()
|
|
input_box.fill("new value")
|
|
```
|
|
|
|
### `click_button_until_disappear(frame, button_name, max_attempts, max_duration)`
|
|
|
|
Continuously clicks a button until it disappears from the DOM. Includes logic to auto-fill missing data before each click.
|
|
|
|
## Development Notes
|
|
|
|
- **Browser launch**: `chromium.launch(headless=False)` for debugging
|
|
- **HTTPS errors**: Ignored with `ignore_https_errors=True` due to self-signed certificates on target system
|
|
- **Locators**: Uses role-based locators (`get_by_role()`) where possible, falling back to CSS selectors and text filtering
|
|
- **Text matching**: Uses regular expressions for matching text with patterns like `re.compile(r"^生产部门$")`
|
|
- **Date format**: "YYYY-MM-DD" (e.g., "2025-12-28")
|
|
- **Language**: Application is in Chinese; comments and print statements use Chinese for clarity
|
|
- **Debugging**: Uses `pdb.set_trace()` for interactive debugging sessions
|
|
|
|
## Target Application Details
