Aperçu général

Amazon CodeWhisperer est le service d'achèvement de code à moteur AI d'AWS qui fournit des suggestions de code intelligentes en temps réel. Il analyse votre code et vos commentaires pour générer des recommandations contextuelles pertinentes, soutenir plusieurs langages de programmation et s'intégrer aux IDE populaires.

C'est pas vrai. Note: CodeWhisperer a été rebaptisé Amazon Q Developer. Cette triche couvre l'interface et les commandes de CodeWhisperer.

Analyse de sécurité

Détection de vulnérabilité

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

Scannage manuel de sécurité

# 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

Résultats de l'analyse de sécurité

# 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

Utilisation de la ligne de commande

Installation CLI

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

# Install via pip
pip install codewhisperer-cli

# Verify installation
codewhisperer --version

CLI Authentification

# Authenticate with AWS Builder ID
codewhisperer auth login

# Use AWS credentials
codewhisperer auth login --profile your-aws-profile

# Check authentication status
codewhisperer auth status

Production de code via CLI

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

# Interactive mode
codewhisperer interactive

Meilleures pratiques

    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()

    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));
        }
    }
