如何使用 Azure DevOps REST API 更新文件？

我正在尝试更新test.json文件托管在 Azure DevOps Repo 上。我正在使用逻辑应用程序。无法从文档中识别操作顺序。

我想我需要...

1. 向以下地址发出 GET HTTP 请求Items端点： https://learn.microsoft.com/en-us/rest/api/azure/devops/git/items/get?view=azure-devops-rest-6.0#get-metadata

   • https://dev.azure.com/myOrg/myProject/_apis/git/repositories/myRepoID/items?scopePath=/data/test.json&$format=json&api-version=6.0
   • 回复：

   {
     "count": 1,
     "value": [
       {
         "objectId": "<longGUID>",
         "gitObjectType": "blob",
         "commitId": "<longGUID>",
         "path": "/data/test.json",
         "url": "https://dev.azure.com/myOrg/longGUID/_apis/git/repositories/myRepoID/items?path=%2Fdata%2Ftest.json&versionType=Branch&versionOptions=None"
       }
     ]
   }
   

2. Use the objectId在响应中发出 POST HTTP 请求Pushes终点 https://learn.microsoft.com/en-us/rest/api/azure/devops/git/pushes/create?view=azure-devops-rest-6.0#add-a-binary-file

   • Body:

{
  "refUpdates": [
    {
      "name": "refs/heads/main",
      "oldObjectId": "<longGuid from previous response>"
    }
  ],
  "commits": [
    {
      "changes": [
        {
          "changeType": "edit",
          "item": {
            "path": "/data/test.json"
          },
          "newContent": {
            "content": "CHECK CHECK!",
            "contentType": "rawtext"
          }
        }
      ],
      "comment": "My commit message"
    }
  ]
}

Error:

• 状态 409 冲突

{
  "$id": "1",
  "innerException": null,
  "message": "TF401028: The reference 'refs/heads/main' has already been updated by another client, so you cannot update it. Please try again.",
  "typeName": "Microsoft.TeamFoundation.Git.Server.GitReferenceStaleException, Microsoft.TeamFoundation.Git.Server",
  "typeKey": "GitReferenceStaleException",
  "errorCode": 0,
  "eventId": 3000
}

问题：

1. 我的操作顺序正确吗？
2. 我该如何克服这个问题？

FIX:（谢谢@Leo_Liu-MSFT）

1. 获取请求至https://dev.azure.com/myOrg/myProject/_apis/git/repositories/repoID/commits?searchCriteria.$top=1&searchCriteria.itemVersion.version=main&api-version=6.0

2. 将请求发送至https://dev.azure.com/myOrg/myProject/_apis/git/repositories/repoID/pushes

• Body:

{
  "commits": [
    {
      "changes": [
        {
          "changeType": "edit",
          "item": {
            "path": "<Your File To Update>"
          },
          "newContent": {
            "content": "CHECK CHECK!",
            "contentType": "rawtext"
          }
        }
      ],
      "comment": "<YOUR COMMIT MSG>"
    }
  ],
  "refUpdates": [
    {
      "name": "refs/heads/main",
      "oldObjectId": "<commitId from previous response>"
    }
  ]
}

The oldObjectId请求正文中的值不是objectId.

应该是分支的最新提交 SHAmain.

• 转到代码页 > 文件
• 选择存储库和分支
• 选择根级别（存储库名称）> 历史记录
• 单击第一个提交的 ... > 复制完整 SHA

价值应该是创建一个新的分支0000000000000000000000000000000000000000当用于创建新分支时。
