在使用 Python 大量请求虾皮商店数据时，可能会遇到各种错误，如网络错误、API 响应错误等。以下是一些常见错误及对应的处理方法： ### 网络错误 网络错误通常是由于网络连接不稳定、超时等原因导致的。可以使用 `try-except` 块来捕获 `requests` 库抛出的异常。 ```python import requests try: response = requests.get('https://partner.shopeemobile.com/api/v2/order/get_order_list') response.raise_for_status() # 检查响应状态码 except requests.exceptions.HTTPError as http_err: print(f'HTTP error occurred: {http_err}') except requests.exceptions.ConnectionError as conn_err: print(f'Connection error occurred: {conn_err}') except requests.exceptions.Timeout as timeout_err: print(f'Timeout error occurred: {timeout_err}') except requests.exceptions.RequestException as req_err: print(f'Other request error occurred: {req_err}') ``` ### API 响应错误 API 可能会返回错误的响应，如状态码不是 200，或者响应内容包含错误信息。可以通过检查响应的状态码和内容来处理这类错误。 ```python import requests response = requests.get('https://partner.shopeemobile.com/api/v2/order/get_order_list') if response.status_code != 200: print(f'API returned status code {response.status_code}') print(response.text) else: data = response.json() if 'error' in data: print(f'API returned error: {data["error"]}') ``` ### 重试机制 对于一些临时性的错误，如网络波动，可以实现重试机制。可以使用 `retry` 库来简化重试逻辑。 ```python import requests from retry import retry @retry(requests.exceptions.RequestException, tries=3, delay=2) def get_order_list(): response = requests.get('https://partner.shopeemobile.com/api/v2/order/get_order_list') response.raise_for_status() return response.json() try: order_list = get_order_list() print(order_list) except requests.exceptions.RequestException as req_err: print(f'Failed after multiple retries: {req_err}') ```
