错误 400：通过 REST API 将 GitLab 存储库导入 Azure DevOps 时出现“错误请求”

Question

我正在尝试使用 REST API 将 GitLab 存储库导入到 Azure DevOps 中。但是，我在此过程中遇到了 400 Bad Request 错误。下面是代码的核心部分：

python代码：

payload = {
"authorization":{"scheme":"UsernamePassword","parameters":{"username":"{User name}","password":"{github access token }"}},
"data":{"accessExternalGitServer":"true"},
"name":"{name}",
"serviceEndpointProjectReferences":[{"description":"","name":"{Service connection name}","projectReference":{"id":"{Project Id}","name":"{Project Name}"}}],
"type":"git",
"url":"{Target Git URL}",
"isShared":false,
"owner":"library"

}

    service_endpoint_url = f"https://dev.azure.com/{ORGANIZATION_NAME}/{project_name}/_apis/serviceendpoint/endpoints?api-version=6.0-preview.4"

    headers = {"Content-Type": "application/json"}

    response = requests.post(
        service_endpoint_url,
        auth=HTTPBasicAuth("", PERSONAL_ACCESS_TOKEN),
        headers=headers,
        data=json.dumps(payload),
        verify=False,
    )

connection_id = response.json()["id"]

# Prepare import request
import_url = f"https://dev.azure.com/{ORG_NAME}/{PROJECT}/_apis/git/repositories/{REPO_NAME}/importRequests?api-version=7.1-preview.1"

import_payload = {
    "parameters": {
        "gitSource": {
            "url": GITLAB_REPO_URL,
            "overwrite": False,
        
        },
        "serviceEndpointId": connection_id,
        "deleteServiceEndpointAfterImportIsDone": True
    }
}

headers = {
    "Content-Type": "application/json"
}

# Perform repository import
import_response = requests.post(
    import_url,
    auth=HTTPBasicAuth("", AZURE_DEVOPS_PAT),  # Placeholder for Azure DevOps PAT
    headers=headers,
    data=json.dumps(import_payload),
    verify=False
)

错误：

400 客户端错误：URL 请求错误：https://dev.azure.com///_apis/git/repositories//importRequests?api-version=7.1-preview.1

我尝试过的事情：

GitLab 存储库 URL (GITLAB_REPO_URL) 正确且可公开访问。 Azure DevOps 个人访问令牌 (AZURE_DEVOPS_PAT) 具有存储库导入和相关操作的完全权限。 存储库名称 (ADO_REPO_NAME) 和项目名称 (PROJECT_NAME) 存在并可在 Azure DevOps 中访问。 GITLAB_REPO_URL 的格式为：https://gitlab.example.com//.git。 我正在根据 Microsoft 文档使用适当的 API 版本 (7.1-preview.1)。 添加服务连接

我在此过程中遇到 400 Bad Request 错误。

问题在于发送到 Azure DevOps 的 REST API 的有效负载的格式或内容。

在这里，我按照以下步骤在我的环境中复制了相同的内容。

下面是在 Azure DevOps 中创建/生成服务端点的代码。

create_service_endpoint.py：

import requests
from requests.auth import HTTPBasicAuth
import json

# Load configurations from the config file
with open("config.json", "r") as config_file:
    config = json.load(config_file)

AZURE_ORGANIZATION = config["azure_organization"]
AZURE_PROJECT = config["azure_project"]
AZURE_DEVOPS_PAT = config["azure_devops_pat"]
GITLAB_REPO_URL = config["gitlab_repo_url"]
GITLAB_USERNAME = config["gitlab_username"]
GITLAB_PERSONAL_ACCESS_TOKEN = config["gitlab_personal_access_token"]
SERVICE_ENDPOINT_NAME = config["service_endpoint_name"]

# Service Endpoint API URL
service_endpoint_url = f"https://dev.azure.com/{AZURE_ORGANIZATION}/{AZURE_PROJECT}/_apis/serviceendpoint/endpoints?api-version=6.0-preview.4"

# Service Endpoint Payload
service_endpoint_payload = {
    "authorization": {
        "scheme": "UsernamePassword",
        "parameters": {
            "username": GITLAB_USERNAME,
            "password": GITLAB_PERSONAL_ACCESS_TOKEN
        }
    },
    "data": {"accessExternalGitServer": "true"},
    "name": SERVICE_ENDPOINT_NAME,
    "serviceEndpointProjectReferences": [
        {
            "description": "",
            "name": SERVICE_ENDPOINT_NAME,
            "projectReference": {
                "id": AZURE_PROJECT,
                "name": AZURE_PROJECT
            }
        }
    ],
    "type": "git",
    "url": GITLAB_REPO_URL,
    "isShared": False,
    "owner": "library"
}

# Request Headers
headers = {"Content-Type": "application/json"}

# Create Service Endpoint
response = requests.post(
    service_endpoint_url,
    auth=HTTPBasicAuth("", AZURE_DEVOPS_PAT),
    headers=headers,
    data=json.dumps(service_endpoint_payload),
    verify=False
)

# Output Results
if response.status_code in [200, 201]:
    service_endpoint_id = response.json()["id"]
    print(f"Service Endpoint created successfully. ID: {service_endpoint_id}")
else:
    print(f"Failed to create Service Endpoint. Status Code: {response.status_code}")
    print(response.text)

在 Azure DevOps 中生成具有服务连接和代码（读取和写入）权限的 PAT。

这是我的 Gitlab 存储库，我还需要在 Gitlab 中生成 PAT。

服务端点创建成功，并返回其ID。

存储库导入请求成功，存储库已导入到 Azure DevOps 中。

Service Endpoint created successfully.
Response:
{
    "id": "12345678-abcd-1234-efgh-1234567890ab",
    "name": "GitLab Service Connection",
    "type": "git",
    "url": "https://gitlab.com/XXXXXxxx/XXXXX.git",
    "authorization": {
        "scheme": "UsernamePassword",
        "parameters": {
            "username": "your-gitlab-username"
        }
    }
}

HTTP 202 已接受

Repository import initiated successfully.
Response:
{
    "id": 42,
    "status": "queued",
    "repository": {
        "id": "abcdef12-3456-7890-abcd-ef1234567890",
        "name": "XXXXXXXXX",
        "url": "https://dev.azure.com/MyOrg/MyProject/_git/Stackoverflow"
    }
}
