Python requests 异常Max retries exceeded with url: 请求地址… (Caused by SSLError(SSLCertVerificationError(1, ‘[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1129)’)))”))}解决

今天在写爬虫的时候遇见了如下错误：

Max retries exceeded with url: https://******... (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1129)')))"))}Python requests 异常

错误大概意思应该是：URL超过了最大重试次数，证书验证失败。

这个错误很好解决，我们在requests请求的地方的加上verify=False参数既可以解决。

如下

import requests
import logging
logging.captureWarnings(True)
r = requests.get(url, timeout=15, verify=False)

你可以看到上面示例代码中还有两句：

import logging
logging.captureWarnings(True)

这是因为如果不加上的话 会出现如下警告信息：

C:\Python\Python39\lib\site-packages\urllib3\connectionpool.py:1043: InsecureRequestWarning: Unverified HTTPS request is being made to host ‘doamin.com’. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/1.26.x/advanced-usage.html#ssl-warnings
warnings.warn(

所以加上logging.captureWarnings(True)就不会弹出警告信息了。

关于Python requests verify参数详细介绍和相关文章，可以看我之前的文章：
