Requests 简明教程

Requests - SSL Certification

SSL证书是安全网址附带的一项安全功能。当您使用 Requests 库时，它也会验证给定 https 网址的 SSL 证书。SSL 验证在 requests 模块中默认启用，如果证书不存在，则会引发错误。

Working with secure URL

以下是使用安全 URL 的示例 −

import requests
getdata = requests.get(https://jsonplaceholder.typicode.com/users)
print(getdata.text)

Output

E:\prequests>python makeRequest.py
[
   {
      "id": 1,
      "name": "Leanne Graham",
      "username": "Bret",
      "email": "Sincere@april.biz",
      "address": {
         "street": "Kulas Light",
         "suite": "Apt. 556",
         "city": "Gwenborough",
         "zipcode": "92998-3874",
         "geo": {
            "lat": "-37.3159",
            "lng": "81.1496"
         }
      },
      "phone": "1-770-736-8031 x56442",
      "website": "hildegard.org",
      "company": {
         "name": "Romaguera-Crona",
         "catchPhrase": "Multi-layered client-server neural-net",
         "bs": "harness real-time e-markets"
      }
   }
]

我们很容易从上述 https 网址获取响应，这是因为 request 模块可以验证 SSL 证书。

您可以通过在示例中所示的方式简单添加 verify=False 来禁用 SSL 验证。

Example

import requests
getdata =
requests.get('https://jsonplaceholder.typicode.com/users', verify=False)
print(getdata.text)

您将获得输出，但它还会给出一条警告消息，即 SSL 证书尚未得到验证，建议添加证书验证。

您还可以通过在自己这边托管 SSL 证书并使用 verify 参数给出路径来验证 SSL 证书，如下所示。

Example

import requests
getdata =
requests.get('https://jsonplaceholder.typicode.com/users', verify='C:\Users\AppData\Local\certificate.txt')
print(getdata.text)

Output

E:\prequests>python makeRequest.py
[
   {
      "id": 1,
      "name": "Leanne Graham",
      "username": "Bret",
      "email": "Sincere@april.biz",
      "address": {
         "street": "Kulas Light",
         "suite": "Apt. 556",
         "city": "Gwenborough",
         "zipcode": "92998-3874",
         "geo": {
            "lat": "-37.3159",
            "lng": "81.1496"
         }
      },
      "phone": "1-770-736-8031 x56442",
      "website": "hildegard.org",
      "company": {
         "name": "Romaguera-Crona",
         "catchPhrase": "Multi-layered   client-server neural-net",
         "bs": "harness real-time e-markets"
      }
   }
]
