如何使用 Azure DevOps REST API 更新文件？

Question

我正在尝试更新托管在 Azure DevOps Repo 上的 test.json 文件。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...

向 Items endpoint:

发出 GET HTTP 请求

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"
    }
  ]
}

在响应中使用 objectId 向 Pushes endpoint
发出 POST HTTP 请求
- 正文：

{
  "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"
    }
  ]
}

错误：

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：

我的操作顺序正确吗？
我该如何解决这个问题？

FIX:（谢谢@Leo_Liu-MSFT）

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

正文：

{
  "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",

    }
  ]
}

How to use Azure DevOps REST API to Update File?

请求体中的oldObjectId不是objectId的值。

它应该是 分支 main 的最新提交 SHA。

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

用于创建新分支时，该值应为创建新分支0000000000000000000000000000000000000000。
