请求 - SSL 认证

---

SSL 证书是一种安全功能，附带安全 URL。当您使用 Requests 库时，它还会验证给定 https URL 的 SSL 证书。默认情况下，请求模块中启用 SSL 验证，如果证书不存在，则会抛出错误。

使用安全 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) 

输出

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"
      }
   }
]

我们很容易从上面的 https URL 得到响应，这是因为请求模块可以验证 SSL 证书。

您只需添加 verify=False 即可禁用 SSL 验证，如下例所示。

例子

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

您将得到输出，但它也会给出一条警告消息，表明 SSL 证书未经过验证，建议添加证书验证。

输出

您还可以通过将 SSL 证书托管在您的一端来验证 SSL 证书，并使用验证参数提供路径，如下所示。

例子

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

输出

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"
      }
   }
