rest - Azure DevOps API - 如何发现字段和选项列表之间的链接

Question

我正在尝试通过 AZDO REST Api 将 Azure DevOps 流程从一个组织复制到另一个组织。我正在复制布局并被卡住，因为在查询源 AZDO 实例时我无法发现自定义字段和选项列表之间的关系。

在我的场景中，我有一个测试工作项类型，我称之为问题。在问题界面上，我创建了一个自定义字段，它是一个选项列表。虽然我可以 retrieve a list of lists通过 Rest API 和 examine the field同样，我无法弄清楚两者之间的关系。

这是部分有效载荷 from the field :

{
    "count": 39,
    "value": [
...
        {
            "referenceName": "Custom.IssueSource",
            "name": "Issue Source",
            "type": "string",
            "description": "Who is this attributed to",
            "required": true,
            "url": "https://dev.azure.com/MYORG/_apis/work/processes/f390103e-7097-4f19-b5b5-f9dbcf92bb6f/behaviors",
            "customization": "custom"
        },
...   ]
}

这是来自 lists get query 的部分有效载荷我使用反复试验来确定是我分配的选项列表:

{
    "count": 10,
    "value": [
...
        {
            "id": "2998d4e4-2bec-4935-98a1-b67a0b0b6d5d",
            "name": "picklist_e854661e-8620-4ad9-be28-b974c5cb3a5d",
            "type": "String",
            "isSuggested": false,
            "url": "https://dev.azure.com/MYORG/_apis/work/processes/lists/2998d4e4-2bec-4935-98a1-b67a0b0b6d5d"
        },
 ...
 ]
}

这是部分 layout response对于 WIT:

{
    "pages": [
        {
            "id": "d0171d51-ff84-4038-afc1-8800ab613160.System.WorkItemType.Details",
            "inherited": true,
            "label": "Details",
            "pageType": "custom",
            "visible": true,
            "isContribution": false,
            "sections": [
                {
                    "id": "Section1",
                    "groups": [
...
                        {
                            "id": "bf03e049-5062-4d82-b91d-4396541fbed2",
                            "label": "Custom",
                            "isContribution": false,
                            "visible": true,
                            "controls": [
                                {
                                    "id": "Custom.IssueSource",
                                    "label": "Issue Source",
                                    "controlType": "FieldControl",
                                    "readOnly": false,
                                    "visible": true,
                                    "isContribution": false
                                }
                            ]
                        }
                    ]
                },
...    ]
}

针对 AZDO Web 界面使用 fiddler，我唯一一次看到对选项列表的引用是从另一个非 AZDO API 到 https://dev.azure.com/MYORG/_apis/Contribution/dataProviders/query

有没有办法通过 AZDO Rest API 发现链接？我看到了 this question which was similar but was about creating the link

Answer 1

弄清楚了。原来你需要从不同的范围查询 - work item tracking而不是 work item tracking process :

https://dev.azure.com/MYORG/_apis/wit/fields/Custom.IssueSource?api-version=5.0-preview.2

返回

{
    "name": "Issue Source",
    "referenceName": "Custom.IssueSource",
    "description": "Who is this attributed to",
    "type": "string",
    "usage": "workItem",
    "readOnly": false,
    "canSortBy": true,
    "isQueryable": true,
     ...
    "isIdentity": false,
--> "isPicklist": true,
    "isPicklistSuggested": false,
--> "picklistId": "2998d4e4-2bec-4935-98a1-b67a0b0b6d5d",
    "url": "https://dev.azure.com/MYORG/_apis/wit/fields/Custom.IssueSource"
}
