VSTS 任务输入 dataSourceBindings 不工作

VSTS task input dataSourceBindings not working

我正在维护一个 VSTS/TFS 扩展,其中包含几个构建任务和一个带有一些数据源的自定义服务端点类型。我需要构建任务中的输入之一是一个 pickList,其中填充了来自服务端点中定义的数据源之一的信息。

这是我在扩展清单中的 endpoint/dataSources 定义:

{
"id": "kiuwan-service-endpoint",
"description": "Kiuwan servide endpoint to connect to the Kiuwan platform",
"type": "ms.vss-endpoint.service-endpoint-type",
"targets": [
    "ms.vss-endpoint.endpoint-types"
],
"properties": {
    "name": "kiuwan",
    "displayName": "Kiuwan Platform",
    "url": {
        "displayName": "Kiuwan URL",
        "value": "https://api.kiuwan.com",
        "helpMarkDown": "The Kiuwan Service Endpoint URL is always https://api.kiuwan.com"
    },
    "dataSources": [
        {
            "name": "TestConnection",
            "endpointUrl": "{{endpoint.url}}/info",
            "resultSelector": "jsonpath:$.username"
        },
        {
            "name": "ListApplications",
            "endpointUrl": "{{endpoint.url}}/apps/list",
            "resultSelector": "jsonpath:$.[*].name"
        }
    ],
    "authenticationSchemes": [
        {
            "type": "ms.vss-endpoint.endpoint-auth-scheme-basic",
            "inputDescriptors": [
                {
                    "id": "username",
                    "name": "Username",
                    "description": "This is your Kiuwan username",
                    "inputMode": "textbox",
                    "isConfidential": false,
                    "validation": {
                        "isrequired": true,
                        "dataType": "string"
                    }
                },
                {
                    "id": "password",
                    "name": "Password",
                    "description": "Yup! this is your Kiuwan password",
                    "inputMode": "passwordBox",
                    "isConfidential": true,
                    "validation": {
                        "isrequired": true,
                        "dataType": "string"
                    }
                }
            ]
        }
    ],
    "helpMarkdown": "<a href=\"https://www.kiuwam.com\" target=\"_blank\"><b>Learn More</b></a>"
    }
}

这是 task.json 文件中的相关任务输入定义和关联的 dataSourceBinding:

"inputs": [
{
    "name": "kiuwanConnection",
    "type": "connectedService:Kiuwan",
    "label": "Kiuwan Service",
    "defaultValue": "",
    "required": true,
    "helpMarkDown": "Kiuwan service connection"
},
{
    "name": "kiuwanappname",
    "type": "pickList",
    "label": "Available Kiuwan applications",
    "required": false,
    "visibleRule": "projectnameselector = kiuwanapp",
    "helpMarkDown": "Select an existing application in Kiuwan to associate results to."
}
],
"dataSourceBindings": [
    {
        "target": "kiuwanappname",
        "endpointId": "$(kiuwanConnection)",
        "dataSourceName": "ListApplications",
        "resultTemplate": "{{#.}}{\"Value\": \"{{.}}\",\"DisplayValue\": \"{{.}}\"},{{/.}}"
    }
]

在我的本地 TFS 2017 上安装扩展进行测试后,我在新服务端点下拉列表中看到了可用的自定义服务类型。我为我的项目定义了一个新的设置正确的凭据。使用我定义的 TestConnection 数据源验证连接。

但是,当我去查看我的构建任务之一应该用来自 dataSource ListApplication 的响应填充的选择列表时,它是空的。

看来问题可能出在我在dataSourceBinding 中定义的小胡子模板上。这是我应该从数据源中的 REST 调用中得到的:

[
   "A Customer Portal",
   "A Fine PHP Application",
   "A Simple Chess Game"
]

应用json路径后。 运行 来自命令行的 mustache 和 dataSourceBinding 中定义的模板,我得到了这个(在这种情况下我没有转义“):

{"Value": "A Customer Portal","DisplayValue": "A Customer Portal"},{"Value": "A Fine PHP Application","DisplayValue": "A Fine PHP Application"},{"Value": "A Simple Chess Game","DisplayValue": "A Simple Chess Game"},

这是我所期望的。

知道为什么这可能不起作用吗?有没有办法调试这个?有什么方法可以知道是否正在对我的服务端点进行调用?除了任务和扩展清单 json 文件中的拼写错误外,这里可能还有不同的失败点(REST 调用 json 路径、小胡子模板……我是瞎子.

非常感谢您提供的任何帮助。最好, J.

首先,如果apps/list API returns数组对象(例如[{"name":"n1"},{"name":"n2"}]),则将jsonpath:$.[*].name替换为jsonpath:$[*].name

其次,RESTAPIreturns一个数组,可以从dataSourceBindings中移除resultTemplate定义:

"dataSourceBindings": [
    {
        "target": "kiuwanappname",
        "endpointId": "$(kiuwanConnection)",
        "dataSourceName": "ListApplications"
    }
]

另一方面,没有办法调试,只能在点击下拉列表控件时捕获请求。
