python请求SSL错误（证书验证失败）

Question

import json
import requests

cert = ("/home/tests/certs/client.crt",
        "/home/tests/certs/client.key")


class TestCart():

    def test_cart(self, **kwargs):
        url = "https://192.168.X.Y/cart"
        cart_data = {
            'id': kwargs.get('id'),
            'items': kwargs.get('items')
        }
        req_data = json.dumps(cart_data)
        resp = requests.post(url,
                             data=req_data,
                             verify="/home/certs/ca.cert",
                             cert=cert)
        print resp.text


if __name__ == '__main__':
    t_cart = TestCart()
    data = {'id': 'ba396e79-0f0f-4952-a931-5a528c9ff72c', 'items': []}
    t_cart.test_cart(**data)

requests.exceptions.SSLError: HTTPSConnectionPool(host='192.168.X.Y', 
port=443): Max retries exceeded with url: /cart (Caused by 
SSLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify

Answer 1

强烈建议更深入地查看请求的优秀文档。它有一个关于SSL证书验证的专门章节解释：

您可以通过验证CA_BUNDLE文件或具有受信任CA证书的目录的路径：

>>> requests.get('https://github.com', verify='/path/to/certfile')

假设您的服务器证书是由ca.crt签名的，您应该将其用于verify参数。
