Claude, un grand modèle de langage (LLM) d’Anthropic, est l’un des modèles d’IA les plus utilisés dans le monde. Une fois que vous aurez appris à récupérer des sites web, vous passerez le plus clair de votre temps à écrire des analyseurs syntaxiques.
Avec les modèles d’IA modernes, nous pouvons en fait automatiser ce processus. Au lieu de passer des heures à analyser un site difficile, un LLM peut le faire pour vous en moins de cinq minutes.
Nous avons déjà publié d’autres tutoriels sur l’utilisation de l’IA pour générer du code rapidement, mais ici, nous allons intégrer Claude dans notre environnement Python. Suivez-nous et automatisez la partie la plus fastidieuse de votre travail.
Création d’un compte anthropique
Pour accéder à l’API Claude, vous devez créer un compte auprès de Anthropic. Vous pouvez le faire en utilisant votre email ou votre compte Google.
Une fois que vous avez un compte, cliquez sur l’onglet “Clés API” et vous pourrez créer une clé API. Une fois que vous l’avez créée, gardez cette clé précieusement. Vous ne pourrez pas la consulter une deuxième fois.
Conservez cette clé dans un endroit sûr, vous ne pourrez pas utiliser l’API sans elle.
Faire une demande de base
Nous ferons notre première demande à Quotes to Scrape. Ce site ne change pas beaucoup et il est conçu pour le scraping éducatif. Cela nous donne une page statique pour tester les réponses de Claude.
Tout d’abord, nous devons installer l’anthropique.
pip install anthropic
La mise en place d’une instance client est assez simple.
#set up the client
client = anthropic.Anthropic(
api_key=ANTHROPIC_API_KEY,
)
Voici la fonction par laquelle nous introduisons tout dans Claude.
#takes in http response and sends its text to claude for processing
def extract_with_claude(response, token_limit=200000, max_tokens_per_chunk=1024):
message = client.messages.create(
model="claude-3-5-haiku-20241022",
max_tokens=2048,
messages=[
{
"role": "user",
"content": f"""
Hello, please parse this chunk of the HTML page and convert it to JSON.
Make sure to strip newlines, remove escape characters, and whitespace:
{response.text}
"""
}
]
)
text = message.to_dict()["content"][0]["text"]
return text
modèle: Le modèle que nous souhaitons utiliser. Nous utilisonsclaude-3-5-haiku-20241022.max_tokensreprésente le nombre maximum de jetons que Claude doit utiliser pour la réponse.- Par défaut, l’API renvoie un objet
Message. Nous utilisonsto_dict()pour le convertir en paires clé-valeur faciles à utiliser.
import re
import requests

ANTHROPIC_API_KEY = "YOUR-ANTHROPIC-API-KEY"
#set up the client

Comprendre les réponses de Claude
Comme nous l’avons mentionné plus haut, Claude renvoie par défaut un objet Message. La méthode to_dict() rend notre réponse un peu plus facile à intégrer dans notre environnement Python. Cependant, elle n’est toujours pas prête à être utilisée. Jetez un coup d’oeil à la réponse ci-dessous.
I'll help you parse this HTML into a JSON format. I'll focus on extracting the quotes, their authors, and tags. Here's the resulting JSON:
```json
{
"quotes": [
{
"text": "The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.",
"author": "Albert Einstein",
"tags": ["change", "deep-thoughts", "thinking", "world"]
},
{
"text": "It is our choices, Harry, that show what we truly are, far more than our abilities.",
"author": "J.K. Rowling",
"tags": ["abilities", "choices"]
},
{
"text": "There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle.",
"author": "Albert Einstein",
"tags": ["inspirational", "life", "live", "miracle", "miracles"]
},
{
"text": "The person, be it gentleman or lady, who has not pleasure in a good novel, must be intolerably stupid.",
"author": "Jane Austen",
"tags": ["aliteracy", "books", "classic", "humor"]
},
{
"text": "Imperfection is beauty, madness is genius and it's better to be absolutely ridiculous than absolutely boring.",
"author": "Marilyn Monroe",
"tags": ["be-yourself", "inspirational"]
},
{
"text": "Try not to become a man of success. Rather become a man of value.",
"author": "Albert Einstein",
"tags": ["adulthood", "success", "value"]
},
{
"text": "It is better to be hated for what you are than to be loved for what you are not.",
"author": "André Gide",
"tags": ["life", "love"]
},
{
"text": "I have not failed. I've just found 10,000 ways that won't work.",
"author": "Thomas A. Edison",
"tags": ["edison", "failure", "inspirational", "paraphrased"]
},
{
"text": "A woman is like a tea bag; you never know how strong it is until it's in hot water.",
"author": "Eleanor Roosevelt",
"tags": ["misattributed-eleanor-roosevelt"]
},
{
"text": "A day without sunshine is like, you know, night.",
"author": "Steve Martin",
"tags": ["humor", "obvious", "simile"]
}
],
"top_tags": [
{"tag": "love", "size": 28},
{"tag": "inspirational", "size": 26},
{"tag": "life", "size": 26},
{"tag": "humor", "size": 24},
{"tag": "books", "size": 22},
{"tag": "reading", "size": 14},
{"tag": "friendship", "size": 10},
{"tag": "friends", "size": 8},
{"tag": "truth", "size": 8},
{"tag": "simile", "size": 6}
]
}
```
I've extracted:
1. The quotes, their text, authors, and associated tags
2. The top tags with their relative sizes
The JSON is clean, without newlines or escape characters, and follows a clear structure. Would you like me to modify the JSON in any way?
Nous recevons le JSON que nous voulons, mais il est intégré dans une chaîne plus large. Nous devons extraire les données de Claude du texte.
Extraction des données de la réponse
Le JSON est intégré dans des backticks, “`, tout comme un bloc de code markdown. Pour obtenir notre réponse, nous allons utiliser une expression rationnelle pour trouver le début et la fin du JSON.
def pull_json_data(claude_text):
json_match = re.search(r"```json\n(.*?)\n```", claude_text, re.DOTALL)
if json_match:
# Extract the JSON and load it into a Python dictionary
parsed_json = json.loads(json_match.group(1))
return parsed_json # Pretty-print the JSON
else:
print("Could not find JSON in the response.")
Voici un exemple de code complet qui imprime uniquement les données extraites de la page.

Traiter les grandes pages
Lorsque nous introduisons une page volumineuse dans Claude, nous nous heurtons à des contraintes liées aux jetons. Claude autorise une limite maximale de 200 000 jetons. Pour que Claude puisse traiter des données plus volumineuses, nous devons diviser nos données en morceaux. Ensuite, Claude peut traiter chaque morceau individuellement.
def chunk_text(text, max_tokens):
"""Split text into sequential chunks based on token limit."""
chunks = []
while text:
# Estimate tokens for the current chunk size
current_chunk = text[:max_tokens * 4] # Rough estimate: 1 token ≈ 4 characters
chunks.append(current_chunk)
text = text[len(current_chunk):] # Move to the next chunk
return chunks
Le code ci-dessus nous donne un algorithme primitif de découpage en morceaux avec lequel travailler. Chaque morceau sera envoyé individuellement à Claude pour être traité.
Claude avec Web Unlocker et Proxies résidentiels
Dans l’exemple suivant, nous intégrerons notre scraper infusé par l’IA aux proxies de Bright Data pour contourner le système de blocage d’Amazon. Cela représente beaucoup moins de travail que de scraper manuellement Amazon. Vous pouvez utiliser le scraper ci-dessous avec Web Unlocker ou nos proxies résidentiels.

Cet exemple est un peu plus raffiné que notre racleur de citations.
- Amazon nous donne des pages de réponses massives. Nous utilisons notre algorithme de découpage pour diviser la page.
- Nous transmettons chaque morceau à Claude par l’intermédiaire d’un client API pour qu’il le traite.
- Nous extrayons le JSON de chaque réponse et l’ajoutons à nos
résultats. Lorsque l’analyse est terminée, nous renvoyons ces résultats. - Après le balayage, nous écrivons les résultats dans un fichier JSON.
Voici la sortie du terminal. La page a été découpée en six morceaux pour être traitée par Claude.
Chunks to process: 6
Processing chunk 1/6...
Processing chunk 2/6...
Processing chunk 3/6...
Processing chunk 4/6...
Processing chunk 5/6...
Processing chunk 6/6...

Conclusion
En permettant à Claude d’analyser les pages avec l’infrastructure de Bright Data, nous pouvons réduire considérablement le temps passé à écrire des analyseurs et à gérer les blocages et les interdictions d’IP. La seule chose dont vous devez vous préoccuper est la page. Une fois que vous avez la page, vous pouvez la confier à Claude pour qu’il la complète. Votre scraper global peut prendre quelques minutes de plus pour fonctionner, mais ce n’est rien comparé aux heures que nous passons à écrire nos propres analyseurs.
