Azure DevOps访问Web扩展中的变量

Question

我需要访问以Html / JavaScript编写的Web扩展的全局变量。

扩展清单：

"targets": [
        {
            "id": "Microsoft.VisualStudio.Services"
        }
    ],
    "contributions": [
        {
            "id": "coverage-web-hub",
            "type": "ms.vss-web.hub",
            "targets": [
                "ms.vss-build-web.build-release-hub-group"
            ],
            "properties": {
                "name": "Coverage",
                "uri": "index.html"
            }
        }
    ],

是否可以通过以下方式访问全局变量：

• 与VSS SDK

• 或其他REST API

通常可以与扩展名共享变量吗？

Answer 1

1。步骤：将范围添加到扩展清单

"scopes": [
        "vso.variablegroups_read",
        "vso.variablegroups_manage"
],

2。步骤：获取您的Azure DevOps URL（inside the VSS.ready() function）

//GET AZURE DEVOPS SERVER URL
var uri = VSS.getWebContext().host.uri
var project = VSS.getWebContext().project.name
var url = uri + project

3。步骤：根据ID验证和读取您的变量组（数字，从1开始）

//AUTHENTIFICATION https://docs.microsoft.com/en-us/azure/devops/extend/develop/auth?view=azure-devops
VSS.require(["VSS/Authentication/Services"],
    function (VSS_Auth_Service) {
        VSS.getAccessToken().then(function (token) {

            //FORMAT THE AUTH HEADER
            var authHeader = VSS_Auth_Service.authTokenManager.getAuthorizationHeader(token);

            //REQUEST AZURE DEVOPS GLOBAL VARIABLES
            var request = new XMLHttpRequest(); //USE 'url' FROM STEP TWO HERE
            request.open("GET", url + "/_apis/distributedtask/variablegroups/1?", false); // 1 = ID OF VARIABLE GROUP; false for synchronous request
            request.setRequestHeader("Authorization", authHeader)
            request.send(null);
            var Json = JSON.parse(request.responseText); //GET VARIABLE GROUP AS JSON
            var Coverage = Json.variables.Coverage.value //VARIABLE NAMED 'Coverage'
            var CoverageHistoryJson = Json.variables.CoverageHistoryJson.value //VARIABLE NAMED 'CoverageHistoryJson'

            console.log("RESULT: " + Coverage)
        });
    });
