TFS 2015.2 中的工作项创建问题（使用 vsts-node-api）

Question

通过 vso-node-api 包在 TFS 2015.2（本地）中创建错误项时出现以下错误，但是相同的代码在我的 VSTS（在线）订阅中运行良好。

错误：请求失败：错误请求 (400) - TF401349：发生意外错误，请验证您的请求并重试。
状态码：400

我正在使用 vso-node-api 库中的 WorkItemTrackingApi/createWorkItem 函数来创建工作项。以下是我用来创建工作项的示例代码。

WorkItemCreator.ts

import * as vm from 'vso-node-api/WebApi';
import * as wa from 'vso-node-api/WorkItemTrackingApi';
import * as wi from 'vso-node-api/interfaces/WorkItemTrackingInterfaces';
import * as vss from 'vso-node-api/interfaces/Common/VSSInterfaces';
import * as core from 'vso-node-api/interfaces/CoreInterfaces';
import tl = require('vsts-task-lib/task');

export class WorkItemCreator {
    workItemType: string = "Bug";
    fieldsToRetrieve: string[] = ["System.State", "System.Title"];

    collectionUrl: string;
    projName: string;
    accessToken: string;
    vstsWI: wa.IWorkItemTrackingApi;
    projectId: string;

    constructor() {
        console.log("Initializing Workitem Creator...");
        console.log("Retrieving enviornment values...");
        this.collectionUrl = process.env["SYSTEM_TEAMFOUNDATIONCOLLECTIONURI"];
        this.projName = process.env["SYSTEM_TEAMPROJECT"];
        this.projectId = process.env["SYSTEM_TEAMPROJECTID"];

        console.log("SYSTEM_TEAMFOUNDATIONCOLLECTIONURI: " + this.collectionUrl);
        console.log("SYSTEM_TEAMPROJECT: " + this.projName);

        this.accessToken = this.getAccessToken();
        let creds = vm.getBearerHandler(this.accessToken);
        let connection = new vm.WebApi(this.collectionUrl, creds);
        this.vstsWI = connection.getWorkItemTrackingApi();
    }

    /**
     * Create Work Items

    public createWorkItems(workItems: Array<BugItem>) {
        workItems.forEach(workItem => {
            let selectWorkItemsQry = { query: "Select [System.Id] From WorkItems Where [System.WorkItemType] = '" + this.workItemType + "' AND [System.Title] = '" + workItem.title + "'" };
            this.getWorkitem(this.projName, this.projectId, selectWorkItemsQry).then((qr: wi.WorkItemQueryResult) => {
                console.log("WorkItem Count:" + qr.workItems.length);
                if (qr.workItems.length == 0) {
                    console.log("Creating WorkItem '" + workItem.title + "' in project '" + this.projName + "'");
                    let xs: string[] = ["TagX", "TagY", "TagZ"];
                    console.log("Tags: " + xs);
                    this.createWorkitem(this.projName, this.workItemType, workItem.title, workItem.description, workItem.severity, xs);
                }
            })
            .catch((e) => {
                    console.error("Failed to retrieve WorkItem by title '" + workItem.title + "' Error: " + e);
            });
        });        
    }

    //Get acces token
    private getAccessToken(): string {
        tl.debug("Getting credentials for local feeds");

            tl.debug("Token retrieved: " + auth.parameters["AccessToken"]);

        }
        else {
            tl.warning("Could not retrieve authentication token for Workitem creation.");
        }
    }


    //Create Workitem
    private createWorkitem(projectName: string, witype: string, title: string, description: string, severity: string, tagsCollection: string[]) {

Answer 1

正如post 指出的那样，允许的 TFS 仅支持 NTLM 和 Kerberos 进行身份验证。我会假设在 MS 更新 TFS 之前，访问令牌永远不是一个选项。

Answer 2

TFS 2015.3 不支持基于令牌的身份验证。另一种方法是使用基本身份验证选项。如果扩展应该与 VSTS 和 TFS 兼容，那么您必须创建一种机制来为每个部署场景使用单独的身份验证机制。 TFS 2017 支持令牌身份验证，因此它可以像 VSTS 一样与 PAT 一起正常工作。
