根因分析
目标服务器的 SSL 证书验证失败，通常是由于自签名证书或过期的 CA 链。
English
SSL certificate verification failed for the target server, often due to self-signed certificates or expired CA chains.
解决方案
-
90% 成功率 Use a custom SSL context with verification
import ssl; ssl_ctx = ssl.create_default_context(); ssl_ctx.load_verify_locations('ca.pem') connector = aiohttp.TCPConnector(ssl=ssl_ctx) async with aiohttp.ClientSession(connector=connector) as session: ... -
70% 成功率 Temporarily disable SSL verification for testing (not for production)
connector = aiohttp.TCPConnector(ssl=False) async with aiohttp.ClientSession(connector=connector) as session: ...
无效尝试
常见但无效的做法:
-
Disabling SSL verification entirely with connector=False
40% 失败
This reduces security and may cause warnings; not recommended for production.
-
Ignoring the error and retrying without changes
90% 失败
The same error will recur because the certificate issue is not addressed.
