这里是cURL和Python中实现的完整示例-用于授权和进行API调用

Question

寻求将JSON API调用集成到Python程序中的一些帮助。

我希望将以下API集成到Python .py程序中，以允许它被调用并打印响应。

API指南指出必须生成承载令牌以允许调用API，这是我成功完成的。但是，我不确定在Python API请求中将此令牌包含为承载令牌身份验证的语法。

我可以使用包含令牌的cURL成功完成上述请求。我试过＆＃34; urllib＆＃34;和＆＃34;请求＆＃34;路线但无济于事。

Answer 1

这只是意味着它希望将其作为标题数据中的一个键

import requests
endpoint = ".../api/ip"
data = {"ip": "1.1.2.3"}
headers = {"Authorization": "Bearer MYREALLYLONGTOKENIGOT"}

print(requests.post(endpoint, data=data, headers=headers).json())

Answer 2

如果您使用的是requests模块，则可以选择编写一个auth类，如“ New Forms of Authentication”中所述：

import requests

class BearerAuth(requests.auth.AuthBase):
    token = None
    def __init__(self, token):
        self.token = token
    def __call__(self, r):
        r.headers["authorization"] = "Bearer " + self.token
        return r

然后您可以发送这样的请求

response = requests.get('https://www.example.com/', auth=BearerAuth('3pVzwec1Gs1m'))

它使您可以像基本auth一样使用相同的auth参数，并且在某些情况下可能会为您提供帮助。

Answer 3

这里是cURL和Python中实现的完整示例-用于授权和进行API调用

cURL

1。授权

您已收到如下访问数据：

Username: johndoe

Password: zznAQOoWyj8uuAgq

Consumer Key: ggczWttBWlTjXCEtk3Yie_WJGEIa

Consumer Secret: uuzPjjJykiuuLfHkfgSdXLV98Ciga

您可以这样调用cURL：

curl -k -d "grant_type=password&username=Username&password=Password" \

                    -H "Authorization: Basic Base64(consumer-key:consumer-secret)" \

                       https://somedomain.test.com/token

或者在这种情况下为：

curl -k -d "grant_type=password&username=johndoe&password=zznAQOoWyj8uuAgq" \

                    -H "Authorization: Basic zzRjettzNUJXbFRqWENuuGszWWllX1iiR0VJYTpRelBLZkp5a2l2V0xmSGtmZ1NkWExWzzhDaWdh" \

                      https://somedomain.test.com/token

答案类似于：

{
    "access_token": "zz8d62zz-56zz-34zz-9zzf-azze1b8057f8",
    "refresh_token": "zzazz4c3-zz2e-zz25-zz97-ezz6e219cbf6",
    "scope": "default",
    "token_type": "Bearer",
    "expires_in": 3600
}

2。调用API

这是您从上面调用一些使用身份验证的API的方式。 Limit和offset只是API可以实现的2个参数的示例。您需要在access_token之后插入上方的"Bearer "。因此，您可以使用上面的身份验证数据来调用一些API：

curl -k -X GET "https://somedomain.test.com/api/Users/Year/2020/Workers?offset=1&limit=100" -H "accept: application/json" -H "Authorization: Bearer zz8d62zz-56zz-34zz-9zzf-azze1b8057f8"

Python

以上内容在Python中实现。我在注释中添加了文本，以便可以复制粘贴代码。

# Authorization data

import base64
import requests

username = 'johndoe'
password= 'zznAQOoWyj8uuAgq'
consumer_key = 'ggczWttBWlTjXCEtk3Yie_WJGEIa'
consumer_secret = 'uuzPjjJykiuuLfHkfgSdXLV98Ciga'
consumer_key_secret = consumer_key+":"+consumer_secret
consumer_key_secret_enc = base64.b64encode(consumer_key_secret.encode()).decode()

# Your decoded key will be something like:
#zzRjettzNUJXbFRqWENuuGszWWllX1iiR0VJYTpRelBLZkp5a2l2V0xmSGtmZ1NkWExWzzhDaWdh


headersAuth = {
    'Authorization': 'Basic '+ str(consumer_key_secret_enc),
}

data = {
  'grant_type': 'password',
  'username': username,
  'password': password
}

## Authentication request

response = requests.post('https://somedomain.test.com/token', headers=headersAuth, data=data, verify=True)
j = response.json()

# When you print that response you will get dictionary like this:

    {
        "access_token": "zz8d62zz-56zz-34zz-9zzf-azze1b8057f8",
        "refresh_token": "zzazz4c3-zz2e-zz25-zz97-ezz6e219cbf6",
        "scope": "default",
        "token_type": "Bearer",
        "expires_in": 3600
    }

# You have to use `access_token` in API calls explained bellow.
# You can get `access_token` with j['access_token'].


# Using authentication to make API calls   

## Define header for making API calls that will hold authentication data

headersAPI = {
    'accept': 'application/json',
    'Authorization': 'Bearer '+j['access_token'],
}

### Usage of parameters defined in your API
params = (
    ('offset', '0'),
    ('limit', '20'),
)

# Making sample API call with authentication and API parameters data

response = requests.get('https://somedomain.test.com/api/Users/Year/2020/Workers', headers=headersAPI, params=params, verify=True)
api_response = response.json()

    final_url = url + list_id + "/data"
    print("Final url is :", final_url)
    headers_api = {
        'Authorization': 'Bearer ' + jwt_token

    }
    try:
        response = requests.get(url=final_url, headers=headers_api)
    except requests.exceptions as err:
        print(err)
        response = 'error'
    return response
