无法在打字稿中使用 createQuery()

Question

我正在尝试使用以下内容创建查询 - https://www.visualstudio.com/en-us/docs/integrate/extensions/reference/client/api/tfs/workitemtracking/restclient/workitemtrackinghttpclient2_2#method_createQuery

我正在使用上述开发一个 vsts 扩展。这是代码-

import { QueryHierarchyItem  } from "TFS/WorkItemTracking/Contracts";
var postedQuery = [

    {
        "children": [],
        "clauses": {
            "field": {
                "referenceName": "System.WorkItemType",
                "name": "Work Item Type",
                "url": "https://fabrikam-fiber-inc.visualstudio.com/DefaultCollection/_apis/wit/fields/System.WorkItemType"
            },
            "operator": {
                "referenceName": "SupportedOperations.Equals",
                "name": "="
            },
            "value": "Bug"
        },

        "columns": [
            {
                "referenceName": "System.Id",
                "name": "ID",
                "url": "https://fabrikam-fiber-inc.visualstudio.com/DefaultCollection/_apis/wit/fields/System.Id"
            },
            {
                "referenceName": "System.Title",
                "name": "Title",
                "url": "https://fabrikam-fiber-inc.visualstudio.com/DefaultCollection/_apis/wit/fields/System.Title"
            },
            {
                "referenceName": "System.State",

                "url": "https://fabrikam-fiber-inc.visualstudio.com/DefaultCollection/_apis/wit/fields/System.State"

        "wiql": "Select [System.Id], [System.Title], [System.State] From WorkItems Where [System.WorkItemType] = 'Bug' order by [Microsoft.VSTS.Common.Priority] asc, [System.CreatedDate] desc",


    }

]



 let queryPath = "Shared Queries";
    let Query: QueryHierarchyItem = postedQuery;

   client.createQuery(Query, "Team_P1", queryPath).then((wi) => {


    },
        (query) => {


        });

Answer 1

首先，你可以参考西里尔的回答。

其次，你可以参考这段代码：

let Query:any={
            name:"Api Query",
            wiql: "Select [System.Id], [System.Title], [System.State] From WorkItems Where [System.WorkItemType] = 'Bug' order by [Microsoft.VSTS.Common.Priority] asc, [System.CreatedDate] desc"
        };
let queryPath = "Shared Queries";


   client.createQuery(Query, "Team_P1", queryPath).then((wi) => {


    },
        (query) => {


        });

Answer 2

默认情况下，tsc 编译器会将错误消息截断为 100 个字符。

您可以通过在 tsconfig.json 文件的 compilerOptions 属性中设置 "noErrorTruncation": true 来更改它。

详情请见Typescript Compiler Options

错误信息是现在（美化后）

'类型' { "children": any[]; "clauses": { "field": { "referenceName": string; "name": string; "url": string; }; "operator": { "referenceName": string; "name": string; }; "value": string; }; "columns": { "referenceName": string; "name": string; "url": string; }[]; "createdBy": { "id": string; "displayName": string; }; "createdDate": string; "filterOptions": string; "hasChildren": boolean; "id": string; "isDeleted": boolean; "isFolder": boolean; "isInvalidSyntax": boolean; "isPublic": boolean; "lastModifiedBy": { "id": string; "displayName": string; }; "lastModifiedDate": string; "name": string; "path": string; "queryType": string; "sortColumns": { "field": { "referenceName": string; "name": string; "url": string; }; "descending": boolean; }[]; "wiql": string; }[] ' 不可分配给类型 'QueryHierarchyItem'。 类型 [重复类型] 中缺少属性“children”。 '

您将 postedQuery 声明为数组 [] 而 QueryHierarchyItem 这就是缺少属性 children 的原因。

如果您删除该数组，您将收到缺少属性等的新错误消息。

顺便说一句，基于this link，看起来您不需要创建整个对象，您可以创建一个空对象并分配所需的参数。

let queryPath = "Shared Queries";
let query: <QueryHierarchyItem>{};
query.Name = 'Query Name'; 
query.wiql = '...'

client.createQuery(query, "Team_P1", queryPath)
      .then(wi => {
          console.log(wi);             
      }, q => {
          console.log(q);
      });
