requestsのインストール

# Importing requests
import requests

print("Requests library imported successfully")

GETリクエストを送信する

# Sending a GET request
import requests

response = requests.get("https://jsonplaceholder.typicode.com/posts/1")
print(response.json())  # Outputs the JSON response

POSTリクエストの送信

# Sending a POST request
import requests

payload = {"title": "foo", "body": "bar", "userId": 1}
response = requests.post("https://jsonplaceholder.typicode.com/posts", json=payload)
print(response.json())  # Outputs the response

レスポンスを処理する

# Handling responses
response = requests.get("https://jsonplaceholder.typicode.com/posts/1")
if response.status_code == 200:
    print("Success:", response.json())
else:
    print("Failed with status code:", response.status_code)

クエリパラメーターを追加する

# Adding query parameters
params = {"userId": 1}
response = requests.get("https://jsonplaceholder.typicode.com/posts", params=params)
print(response.json())

ヘッダーを追加する

# Adding headers
headers = {"Authorization": "Bearer YOUR_API_KEY"}
response = requests.get("https://jsonplaceholder.typicode.com/posts", headers=headers)
print(response.status_code)

エラーを処理する

# Handling errors
try:
    response = requests.get("https://jsonplaceholder.typicode.com/invalid")
    response.raise_for_status()
except requests.exceptions.HTTPError as err:
    print("HTTP error occurred:", err)
except requests.exceptions.RequestException as err:
    print("Request error occurred:", err)
