I am trying to use rest to create fields and picklists, on the web site I created a field as type picklist String and added some items to the list:
字段的其余 URL：https://dev.azure.com/ https://dev.azure.com/{org}/_apis/work/processes/{processId}/workitemtypes/CMMI2.Bug/fields/Custom.AppType?api-version=5.0-preview.2
它返回这个：
{
referenceName: "Custom.AppType",
name: "AppType",
type: "string",
description: "",
url: "https://dev.azure.com/{org}/_apis/work/processes/bd96307e-3d16-44ac-b498-be1a8daff2d5/behaviors",
customization: "custom"
}
选择列表的其余 URL：https://dev.azure.com/ https://dev.azure.com/{org}/_apis/work/processes/lists/{picklistId}?api-version=5.0-preview.1 这返回：
{
items: [
"All",
"Item2",
"Item3"
],
id: "{picklistId}",
name: "picklist_{diffGuidFromPickListId}",
type: "String",
isSuggested: false,
url: "https://dev.azure.com/{org}/_apis/work/processes/lists/{picklistId}"
}
这是这方面的文档：https://learn.microsoft.com/zh-cn/rest/api/azure/devops/processes/fields/get?view=azure-devops-rest-5.0#processworkitemtypefield https://learn.microsoft.com/zh-cn/rest/api/azure/devops/processes/fields/get?view=azure-devops-rest-5.0#processworkitemtypefield
首先 - 为什么字段类型应该是 picklistString （根据文档链接）？
其次 - 选项列表如何链接到字段？
thanks
picklistString指的是类型的名称，它的实际属性是string，所以它在type中显示的字段类型是string。
其次 - 选项列表如何链接到字段？
(1) 为了实现这一点，你可以使用这个API https://learn.microsoft.com/en-us/rest/api/azure/devops/wit/fields/create?view=azure-devops-rest-5.1:
POST https://dev.azure.com/{organizationName}/{projectName}/_apis/wit/fields?api-version=5.1-preview.2
这是我的请求正文供您参考：
{
"name": "{FieldName}",
"referenceName": "{the reference name of WIT},
"type": "string",
"usage": "workItem",
"readOnly": false,
"canSortBy": true,
"isQueryable": true,
"supportedOperations": [
{
"referenceName": "{the reference name of WIT}"
"name": "="
}
],
"isIdentity": true,
"isPicklist": true,
"isPicklistSuggested": false,
"url": null
}
Note: Set 是选择列表 as true，您可以将选项列表链接到这个新字段。
(2) UI操作，只需添加新字段，打开下拉列表type并选择 picklist(string)/picklist(Integer) 作为您需要的。
和...之间的不同picklist(string) and picklist(Integer)就是它picklist(string)允许选择短文本字符串（255 个字符或更少）值的列表，以及picklist(Integer)包含整数值的选择列表 https://learn.microsoft.com/en-us/azure/devops/boards/queries/query-operators-variables?view=azure-devops.
