使用 vsts rest api 将 git repo 从一个 vsts 团队项目导入另一个团队项目

Question

想要启动从项目 A 到项目 B 的 VSTS git repo 导入。编写以下脚本以通过 REST API 创建导入请求。它给出了错误的请求 400，如下所述。有什么线索吗？

param(
    <parameter(mandatory=$true)>
    [string] $token,
    <parameter(mandatory=$true)>
    [string] $collectionUri,
    <parameter(mandatory=$true)>
    [string] $TargetTeamProject,
    <parameter(mandatory=$true)>
    [string] $TargetGitRepoName,
    <parameter(mandatory=$true)>
    [string] $SourceGitRepoUrl
)
$User=""

$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $User,$token)));
$header = @{Authorization=("Basic {0}" -f $base64AuthInfo)};
$Uri = $collectionUri + $TargetTeamProject + '/_apis/git/repositories/' + $TargetGitRepoName + '/importRequests?api-version=4.1-preview.1'
$ImportRequestData = '{"parameters": {"gitSource": {"url": "' + $SourceGitRepoUrl + '"}}}'
write-host 'calling:' $Uri
write-host 'with data:' $ImportRequestData
$ImportResponse = Invoke-RestMethod -Method Post -ContentType application/json -Uri $Uri -Body $ImportRequestData -Headers $header
$ImportResponse

调用它

.\CreateImportRequest.ps1 -token '*************************************' -collectionUri 'https://myvsts.visualstudio.com/DefaultCollection/' -TargetTeamProject 'HasiTempJava' -TargetGitRepoName 'impfromhasiJava' -SourceGitRepoUrl 'https://myvsts.visualstudio.com/DefaultCollection/_git/HasiJava'

当传递现有的空仓库时，它会抛出错误的请求异常

    Invoke-RestMethod : The remote server returned an error: (400) Bad Request.
    At C:\Users\chamindac\Desktop\CreateImportRequest.ps1:33 char:19
    + ... tResponse = Invoke-RestMethod -Method Post -ContentType application/j ...
    +                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException

    When a new repo name used it is giving below error which is correct I believe since url refers to a non existing repo

<parameter(mandatory=$true)><parameter(mandatory=$true)><parameter(mandatory=$true)><parameter(mandatory=$true)><parameter(mandatory=$true) class="">Invoke-RestMethod : {"$id":"1","innerException":null,"message":"TF401019: The Git repository with name or identifier impfromhasiJavaNew does not exist or you do not have permissions for the operation you are 
attempting.","typeName":"Microsoft.TeamFoundation.Git.Server.GitRepositoryNotFoundException, Microsoft.TeamFoundation.Git.Server","typeKey":"GitRepositoryNotFoundException","errorCode":0,"eventId":3000}

As per documentation (https://docs.microsoft.com/en-us/rest/api/vsts/git/import%20requests/create) only required parameter is the source git repo url. Is there any additional parameter requirements?

您需要将源代码库（来自项目 A）添加为目标项目（项目 B）的外部 Git 端点，然后提供参数 serviceEndpointId 为create import requests REST API。 详细步骤广告如下：

1. 在目标项目中创建外部 Git 端点

   在项目 B -> Services Hub (https://account.visualstudio.com/projectB/_admin/_services) -> 新服务端点 -> 外部 Git -> 添加来自项目 A 的源代码库作为服务器 URL (https://account.visualstudio.com/projectA/_git/sourcerepo) -> 确定。

2. 获取端点id

   如下使用REST API：

   GET https://marinaliu.visualstudio.com/GitTest/_apis/serviceendpoint/endpoints/?api-version=4.1-preview.1
   

   然后从响应中获取端点ID（假设它是c534772b-bf52-442f-abd0-544d6bf76ed9）。

3. 将 git repo 导入目标项目

   然后将项目 A 中的源 repo 导入到项目 B：

   POST https://account.visualstudio.com/projectB/_apis/git/repositories/targetrepo/importRequests?api-version=4.1-preview.1
   

   应用程序/json：

   {
     "parameters": {
       "gitSource": {
         "url": "https://marinaliu.visualstudio.com/projectA/_git/sourcerepo"
       },
       "serviceEndpointId": "c534772b-bf52-442f-abd0-544d6bf76ed9"
     }
   }
