如何编写python脚本以对Azure DevOps REST API进行身份验证并获取访问令牌? [英] How to write a python script to authenticate to Azure DevOps REST API and get the access token?

问题描述

如何在python脚本中向Azure DevOps REST API进行身份验证? 我发现有2种方法:

How can I authenticate to Azure DevOps REST API in a python script? I found that there are 2 methods :

• 使用个人访问令牌(PAT)
• 使用OAuth 2.0

我正在使用第二种方法.遵循了本文档中的步骤: https://docs.microsoft.com/zh-CN/azure/devops/integrate/get-started/authentication/oauth?view=azure-devops

I am using the second method. Followed the steps in this documentation: https://docs.microsoft.com/en-us/azure/devops/integrate/get-started/authentication/oauth?view=azure-devops

我编写了此函数，以使用OAuth 2.0对Azure DevOps进行身份验证:

I wrote this function to autherize to azure DevOps using OAuth 2.0:

def get_authenticated():

    client_id = < my client ID as a string >
    state = "user1"
    scope = "vso.graph_manage%20vso.identity_manage%20vso.profile_write%20vso.project_manage%20vso.tokenadministration%20vso.tokens"
    callback_URL = < Callback URL to my azure devops account >

    # Azure DevOps Services authorization endpoint
    Auth_URL = "https://app.vssps.visualstudio.com/oauth2/authorize?client_id=" + client_id + "&response_type=Assertion&state=" + state + "&scope=" + scope + "&redirect_uri=" + callback_URL
    headers = {'Accept': 'application/json;api-version=1.0'}

    print(Auth_URL)

    response = requests.get(Auth_URL,headers = headers)
    print(response)
    print(response.status_code)
    print(response.headers['content-type'])

    response.raise_for_status() 

但是当调用此函数时，我得到的输出是:

But when calling this function, output I am getting is:

<Response [203]>
203
text/html; charset=utf-8

身份验证URL是正确的，因为当我尝试在浏览器中访问相同的URL时，它会成功重定向到表单以输入azure用户凭据.

The auth URL is correct because when I tried to access the same URL in a browser it successfully redirects to a form to enter azure user credentials.

该脚本的预期行为是，当请求auth_url时，Azure DevOps Services应要求用户进行授权.我认为应该通过在终端中/通过浏览器提示输入用户名和密码来实现.

The expected behavior of the script is, when the auth_url is requested, Azure DevOps Services should ask the user to authorize. I think that should be done by prompting for username&password in terminal/via a browser.

我对python脚本和REST API完全陌生. 有人可以通过指出我的代码中的错误或指出一些示例来帮助我吗?

I am totally new to python scripting and REST APIs. Can someone help me by pointing out the faults in my code or pointing to some samples?

推荐答案

http错误203表示返回的元信息不是来自带有对象副本的服务器的对象的确定集，而是来自私有覆盖的对象网络.在您的代码中，添加了headers = {'Accept': 'application/json;api-version=1.0'}，但实际上内容类型应该为application/x-www-form-urlencoded.

The http error 203 indicates that the returned metainformation is not a definitive set of the object from a server with a copy of the object, but is from a private overlaid web. In your code,you added headers = {'Accept': 'application/json;api-version=1.0'}, but in fact the content type should be application/x-www-form-urlencoded.

您可以使用某些OAuth2库(用于python)对Azure DevOps REST API进行身份验证，例如 OAuthLib .它包括世俗的样本.

You can use some OAuth2 library for python to authenticate to Azure DevOps REST API, such as OAuthLib. It includes sevelral samples.
