能否通过编程获取VSTS/TFS Online账户下所有用户信息，无需成员ID？

Hey there! Let's break down your questions about accessing user data in VSTS/TFS Online programmatically:

1. Can I programmatically retrieve all users in a VSTS account? #

Absolutely! You can use the Azure DevOps Graph REST API to pull a full list of all users in your organization. This API is built specifically for identity-related queries, making it perfect for this task.

Here's what you need to get started:

• Permissions: You’ll need an account with Organization Reader access or higher, plus a Personal Access Token (PAT) with the Graph (Read) scope enabled.
• API Endpoint: Use this GET request to fetch all users:

  GET https://vssps.dev.azure.com/{your-organization-name}/_apis/graph/users?api-version=7.1-preview.1
  

• Example with curl:

  curl -u :{your-PAT} "https://vssps.dev.azure.com/MyOrg/_apis/graph/users?api-version=7.1-preview.1"
  

The response will include key details for every user, like display name, email address (mail), account name (principalName), and unique identity ID.

2. Can I fetch user info using just an account name or email (without needing member/owner IDs)? #

Yes, you don’t need pre-existing member or owner IDs! The same Graph API supports filtering with the $filter parameter, which lets you target users directly by their email or account name.

Examples of filtered requests: #

• Filter by exact email:

  GET https://vssps.dev.azure.com/{your-organization-name}/_apis/graph/users?api-version=7.1-preview.1&$filter=mail eq 'user@example.com'
  

• Filter by exact account name (principalName):

  GET https://vssps.dev.azure.com/{your-organization-name}/_apis/graph/users?api-version=7.1-preview.1&$filter=principalName eq 'DOMAIN\\username'
  

• Fuzzy match (contains): If you need broader results (e.g., all users with "example" in their email), use the contains operator:

  GET https://vssps.dev.azure.com/{your-organization-name}/_apis/graph/users?api-version=7.1-preview.1&$filter=contains(mail, 'example')
  

Authenticate with your PAT just like the full user list request, and the response will return only the matching user(s) with the details you need (account name, email, etc.).
