使用Python请求时返回HTTP状态203的Azure DevOps REST API

Question

我看到了这个关于Python请求的问题，该问题试图对Azure DevOps REST API进行身份验证，并接收HTTP Status 203（非权威信息）。当查看文本响应时，它只是登录页面的HTML，而不是实际登录我。我使用了REST API页面上列出的Authorization:Basic ，但它似乎不起作用。下面是我的代码示例：

"""Using Python and Requests to interact with Azure DevOps REST API
"""


import base64
import pprint as pp
import requests


with open('ado_pat.txt', 'r') as file:
    PERSONAL_AUTHENTICATION_TOKEN = file.read().replace('\n', '')

PAT_BASE_64 = base64.b64encode(
    b'{PERSONAL_AUTHENTICATION_TOKEN}').decode('ascii')
COLLECTION = 'collection_name'
ORGANIZATION_URL = f'https://dev.azure.com/{COLLECTION}'
RESOURCE_PATH = '/_apis/projects?api-version=5.1'
HEADERS = {
    'Authorization': f'Basic {PAT_BASE_64}',
    'Accept': 'application/json'
}

try:
    ADO_RESPONSE = requests.get(
        ORGANIZATION_URL + RESOURCE_PATH, headers=HEADERS)

    pp.pprint(ADO_RESPONSE)
    pp.pprint(ADO_RESPONSE.text)
    ADO_RESPONSE.raise_for_status()
except requests.exceptions.HTTPError as err:
    pp.pprint(err)

<Response [203]>
(''\r\n'

"""Using Python and Requests to interact with Azure DevOps REST API

import base64
import pprint as pp
import requests


with open('ado_pat.txt', 'r') as file:
    PERSONAL_AUTHENTICATION_TOKEN = file.read().replace('\n', '')

USERNAME = ""
USER_PASS = USERNAME + ":" + PERSONAL_AUTHENTICATION_TOKEN
B64USERPASS = base64.b64encode(USER_PASS.encode()).decode()

COLLECTION = 'collection_name'
ORGANIZATION_URL = f'https://dev.azure.com/{COLLECTION}'
RESOURCE_PATH = '/_apis/projects?api-version=5.1'
HEADERS = {
    'Authorization': 'Basic %s' % B64USERPASS
}

try:
    ADO_RESPONSE = requests.get(
        ORGANIZATION_URL + RESOURCE_PATH, headers=HEADERS)

    pp.pprint(ADO_RESPONSE)
    pp.pprint(ADO_RESPONSE.text)
    ADO_RESPONSE.raise_for_status()
except requests.exceptions.HTTPError as err:
    pp.pprint(err)

使用一个注释的链接，我能够让上面的代码工作。这是最终结果的工作代码。

"""Using Python and Requests to interact with Azure DevOps REST API
"""


import base64
import json
import pprint as pp
import requests


with open('ado_pat.txt', 'r') as file:
    PERSONAL_AUTHENTICATION_TOKEN = file.read().replace('\n', '')

USERNAME = ""
USER_PASS = USERNAME + ":" + PERSONAL_AUTHENTICATION_TOKEN
B64USERPASS = base64.b64encode(USER_PASS.encode()).decode()

COLLECTION = 'collection_name'
ORGANIZATION_URL = f'https://dev.azure.com/{COLLECTION}'
RESOURCE_PATH = '/_apis/securitynamespaces?api-version=5.1'
HEADERS = {
    'Authorization': 'Basic %s' % B64USERPASS
}

try:
    ADO_RESPONSE = requests.get(
        ORGANIZATION_URL + RESOURCE_PATH, headers=HEADERS)

    pp.pprint(ADO_RESPONSE)
    pp.pprint(ADO_RESPONSE.text)
    ADO_RESPONSE.raise_for_status()
except requests.exceptions.HTTPError as err:
    pp.pprint(err)


with open('output.json', 'w') as file:
    file.write(json.dumps(ADO_RESPONSE.json(), indent=4))

似乎API文档没有指定如何正确地编码PAT并且需要修改。
