Panoramica

Amazon CodeWhisperer è il servizio di completamento del codice basato su intelligenza artificiale di AWS che fornisce suggerimenti intelligenti per il codice in tempo reale. Analizza il codice e i commenti per generare raccomandazioni contestualmente rilevanti, supportando più linguaggi di programmazione e integrandosi con IDE popolari.

⚠️ Nota: CodeWhisperer è stato rinominato Amazon Q Developer. Questa scheda di riferimento copre l'interfaccia e i comandi legacy di CodeWhisperer.

Scansione Sicurezza

Rilevamento Vulnerabilità

# Automatic security scanning
# Detects common vulnerabilities:
# - SQL injection
# - Cross-site scripting (XSS)
# - Hardcoded credentials
# - Insecure cryptographic practices
# - Path traversal vulnerabilities

Scansione Sicurezza Manuale

# VS Code:
# 1. Open Command Palette (Ctrl+Shift+P)
# 2. Type "CodeWhisperer Security Scan"
# 3. Select files to scan
# 4. Review results in Problems panel

# JetBrains:
# 1. Tools > AWS > CodeWhisperer > Security Scan
# 2. Select scope (file/project)
# 3. Review results in inspection panel

Risultati Scansione Sicurezza

# High severity issues:
# - Critical security vulnerabilities
# - Immediate attention required
# - Detailed remediation steps provided

# Medium/Low severity:
# - Potential security concerns
# - Best practice recommendations
# - Code quality improvements

Utilizzo Riga di Comando

Installazione CLI

# Install via npm
npm install -g @amzn/codewhisperer-cli

# Install via pip
pip install codewhisperer-cli

# Verify installation
codewhisperer --version

Autenticazione CLI

Would you like me to continue with the remaining sections?```bash

Authenticate with AWS Builder ID

codewhisperer auth login

Use AWS credentials

codewhisperer auth login --profile your-aws-profile

Check authentication status

codewhisperer auth status ```### Generazione di Codice tramite CLI

# Generate code from prompt
codewhisperer generate --prompt "Python function to sort dictionary by values"

# Generate with context file
codewhisperer generate --prompt "Add error handling" --context main.py

# Interactive mode
codewhisperer interactive
```## Migliori Pratiche
```python
# Good: Specific and descriptive comments
# Function to validate email format using regex and return boolean
def validate_email(email):
    # CodeWhisperer generates accurate implementation

# Bad: Vague comments
# Email function
def email_func():
    # Less accurate suggestions
```### Prompt Efficaci
```bash
# Always review generated code:
# 1. Check for logical correctness
# 2. Verify security implications
# 3. Ensure code style consistency
# 4. Test functionality thoroughly
# 5. Validate error handling
```### Revisione del Codice
```bash
# Review security scan results regularly
# Don't ignore vulnerability warnings
# Validate all input parameters
# Use secure coding practices
# Keep dependencies updated
```### Considerazioni sulla Sicurezza

Troubleshooting

Common Issues

# CodeWhisperer not working:
# 1. Check internet connection
# 2. Verify authentication status
# 3. Restart IDE
# 4. Update AWS Toolkit extension

# No suggestions appearing:
# 1. Check if CodeWhisperer is enabled
# 2. Verify file type is supported
# 3. Check automatic trigger settings
# 4. Try manual trigger (Alt+C)

Performance Issues

# Slow suggestions:
# 1. Close unnecessary files
# 2. Reduce project size
# 3. Check network connectivity
# 4. Update to latest extension version

# High CPU usage:
# 1. Adjust suggestion frequency
# 2. Disable automatic triggers
# 3. Use manual triggers only
# 4. Configure suggestion limits

Debug Information

# VS Code debug info:
# 1. View > Output
# 2. Select "AWS Toolkit" from dropdown
# 3. Check for error messages

# JetBrains debug info:
# 1. Help > Show Log in Explorer
# 2. Look for AWS-related log files
# 3. Check for error patterns

Code Examples

Python Data Processing

# Function to process CSV file and calculate statistics
import pandas as pd
import numpy as np

def process_sales_data(file_path):
    df = pd.read_csv(file_path)

    # Calculate key metrics
    total_sales = df['amount'].sum()
    avg_sale = df['amount'].mean()
    top_products = df.groupby('product')['amount'].sum().sort_values(ascending=False).head(5)

    return {
        'total_sales': total_sales,
        'average_sale': avg_sale,
        'top_products': top_products.to_dict()
    }

JavaScript API Integration

// Function to fetch user data with error handling and retry logic
async function fetchUserData(userId, maxRetries = 3) {
    for (let attempt = 1; attempt <= maxRetries; attempt++) {
        try {
            const response = await fetch(`/api/users/${userId}`);

            if (!response.ok) {
                throw new Error(`HTTP error! status: ${response.status}`);
            }

            const userData = await response.json();
            return userData;

        } catch (error) {
            console.error(`Attempt ${attempt} failed:`, error.message);

            if (attempt === maxRetries) {
                throw new Error(`Failed to fetch user data after ${maxRetries} attempts`);
            }

            // Wait before retry
            await new Promise(resolve => setTimeout(resolve, 1000 * attempt));
        }
    }
}

Java Spring Boot Controller

// REST controller for product management with validation
@RestController
@RequestMapping("/api/products")
@Validated
public class ProductController {

    @Autowired
    private ProductService productService;

    @PostMapping
    public ResponseEntity<Product> createProduct(@Valid @RequestBody ProductDTO productDTO) {
        try {
            Product product = productService.createProduct(productDTO);
            return ResponseEntity.status(HttpStatus.CREATED).body(product);
        } catch (ValidationException e) {
            return ResponseEntity.badRequest().build();
        } catch (Exception e) {
            return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
        }
    }
}
