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

Question

I saw this question 关于 Python requests 尝试对 Azure DevOps REST API 进行身份验证并接收 HTTP 状态 203，非权威信息。查看文本响应时，它只是登录页面的 HTML，并没有真正让我登录。我使用了 Authorization: Basic <BASE64 PAT> listed on their REST API page，但它似乎不起作用。这是我的代码示例：

"""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)

这是我得到的回复：

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

然后它会显示整个登录页面。我会使用microsoft/azure-devops-python-api，但我并不真正理解或看不到我可以调用的方法，也不真正理解它是如何工作的。

--编辑工作示例--

这个例子现在可以工作了。

"""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)

Using a comment's link，我能够让上面的代码正常工作。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))

API 文档似乎没有指定如何正确编码 PAT，需要重新修改。
