VSTS 扩展 - 从构建任务存储参数并从摘要选项卡调用 Web 服务

Question

我需要在摘要选项卡（“ms.vss-build-web.build-results-section”）中显示自定义构建任务的结果。为了做到这一点，我需要从构建任务中保留一些数据，并使用它从摘要部分调用 Web 服务。是否可以使用扩展数据服务将数据存储在变量中并在摘要页面中使用？最好的方法应该是什么？

提前致谢。

我已使用 Logging 命令附加了我的构建任务数据

https://github.com/Microsoft/vsts-tasks/blob/986f8f5112017474962affe58c9ebaf394fb9354/docs/authoring/commands.md

//Build Task

class TestClass {
    _name: string;
    _age: number;

    constructor(name: string, age:number) {
        this._name = name;
        this._age = age;
    }
}

var data = new TestClass(TinTin,100);

//Create a folder
tl.mkdirP("c:/myfolder/");

//Write data to a file
tl.writeFile("c:/myfolder/mydata.txt",JSON.stringify(data));

//Executes command to attach the file to build
console.log("##vso[task.addattachment type=myAttachmentType;name=myAttachmentName;]c:/myfolder/mydata.txt");

从摘要页面检索附件。

					var recId = taskAttachments[0].recordId;
					var timelineId = taskAttachments[0].timelineId;

					taskClient.getAttachmentContent(vsoContext.project.id, "build", build.orchestrationPlan.planId,timelineId,recId,"myAttachmentType","myAttachmentName").then((attachementContent)=> {														
						function arrayBufferToString(buffer){
									var arr = new Uint8Array(buffer);
									var str = String.fromCharCode.apply(String, arr);

									}
									return str;
								}
						
						var summaryPageData = arrayBufferToString(attachementContent);
						
						//Deserialize data
						var ob = JSON.parse(summaryPageData);
						console.log("Name: " + ob._name);
						console.log("Age: " + ob._age);

					});					
				}
				});	
			});
		}		
	}	
}

StatusSection.enhance(StatusSection, $(".build-status"), {});

// Notify the parent frame that the host has been loaded
VSS.notifyLoadSucceeded();

您可以这样做，但问题是这些值始终是最新版本的值，摘要页面中的信息对于旧版本是不正确的。所以我建议通过BuildHttpClient2_2获取构建任务结果，然后直接显示在摘要页面中。
