错误处理最佳实践

¥Error Handling Best Practices

1. 始终使用等待

¥1. Always Use Waits

# Bad - element might not be ready
CLICK `#button`

# Good - wait for element first
WAIT `#button` 5
CLICK `#button`

2.处理可选元素

¥2. Handle Optional Elements

# Check before interacting
IF (EXISTS `.popup`) THEN CLICK `.close`
IF (EXISTS `.cookie-banner`) THEN CLICK `.accept`

# Then proceed with main flow
CLICK `#main-action`

3.使用描述性变量

¥3. Use Descriptive Variables

# Set up reusable data
SETVAR admin_email = "admin@company.com"
SETVAR test_password = "TestPass123!"
SETVAR staging_url = "https://staging.example.com"

# Use throughout script
GO $staging_url
TYPE $admin_email

4.添加调试信息

¥4. Add Debugging Information

# Log progress
EVAL `console.log("Starting login process")`
GO /login

# Verify page state
IF (`document.title.includes("Login")`) THEN EVAL `console.log("On login page")`

# Continue with login
TYPE $username

常见模式

¥Common Patterns

登录流程

¥Login Flow

# Complete login automation
SETVAR email = "user@example.com"
SETVAR password = "mypassword"

GO /login
WAIT `#login-form` 5

# Handle optional cookie banner
IF (EXISTS `.cookie-banner`) THEN CLICK `.accept-cookies`

# Fill and submit form
CLICK `#email`
TYPE $email
PRESS Tab
TYPE $password
CLICK `button[type="submit"]`

# Wait for redirect
WAIT `.dashboard` 10

无限滚动

¥Infinite Scroll

# Load all content with infinite scroll
GO /products

# Scroll and load more content
REPEAT (SCROLL DOWN 500, `document.querySelector(".load-more")`)

# Alternative: Fixed number of scrolls
REPEAT (SCROLL DOWN 800, 10)
WAIT 2

表单验证

¥Form Validation

# Handle form with validation
SET `#email` "invalid-email"
CLICK `#submit`

# Check for validation error
IF (EXISTS `.error-email`) THEN SET `#email` "valid@example.com"

# Retry submission
CLICK `#submit`
WAIT `.success-message` 5

多步骤流程

¥Multi-step Process

# Complex multi-step workflow
PROC navigate_to_step
  CLICK `.next-button`
  WAIT `.step-content` 5
ENDPROC

# Step 1
WAIT `.step-1` 5
SET `#name` "John Doe"
navigate_to_step

# Step 2
SET `#email` "john@example.com"
navigate_to_step

# Step 3
CLICK `#submit-final`
WAIT `.confirmation` 10

与 Crawl4AI 集成

¥Integration with Crawl4AI

使用 C4A-Script 与 Crawl4AI 进行动态内容交互:

¥Use C4A-Script with Crawl4AI for dynamic content interaction:

from crawl4ai import AsyncWebCrawler, CrawlerRunConfig

# Define interaction script
script = """
# Handle dynamic content loading
WAIT `.content` 5
IF (EXISTS `.load-more-button`) THEN CLICK `.load-more-button`
WAIT `.additional-content` 5

# Accept cookies if needed
IF (EXISTS `.cookie-banner`) THEN CLICK `.accept-all`
"""

config = CrawlerRunConfig(
    c4a_script=script,
    wait_for=".content",
    screenshot=True
)

async with AsyncWebCrawler() as crawler:
    result = await crawler.arun("https://example.com", config=config)
    print(result.markdown)
