retryable-requests

易于使用的可重试请求会话。

快速入门

常见情况

from retryable_requests import RetryableSession

with RetryableSession() as session:
    session.get('https://httpbin.org/get')  # will be retried up to 5 times

仅对429错误进行重试

from requests.packages.urllib3.util.retry import Retry
from retryable_requests import RetryableSession

retry_strategy = Retry(
    total=5,
    status_forcelist=[429],
    backoff_factor=0.1,
)

with RetryableSession(retry_strategy=retry_strategy) as session:
    session.get('https://httpbin.org/get')  # will be retried up to 5 times, only for 429 errors

为每个请求自动使用基本URL

from retryable_requests import RetryableSession

with RetryableSession('https://httpbin.org/') as session:
    session.get('get')  # 'https://httpbin.org/get' will be retried up to 5 times
    session.post('post')  # 'https://httpbin.org/post' won't be retried (POST request)

特性

• 自动后退重试失败的请求，这些请求可以安全地重试
• 快速超时非响应请求
