VSTS任务输入dataSourceBindings无效

我正在维护VSTS / TFS扩展,其中包含一些构建任务和一些带有一些dataSource的自定义服务端点类型。我需要构建任务中的一个输入是一个pickList,其中填充的信息来自服务端点中定义的一个dataSource。

这是扩展清单中的端点/ 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上安装扩展程序进行测试后,我看到新服务端点下拉列表中提供的自定义服务类型。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时,应该使用dataSource ListApplication的响应来填充选择列表,它是空的。

似乎问题可能是我在dataSourceBinding中定义的moustche模板。这是我应该从dataSource中的REST调用中获得的:

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

应用jsonpath之后。使用dataSourceBinding中定义的模板从命令行运行小胡子,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"},

这是我的期望。

为什么这可能不起作用的任何想法?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呼叫?除了在任务和扩展清单json文件中的拼写错误中可能存在拼写错误之外,这里可能存在不同的失败点(REST调用jsonpath,小胡子模板......我是盲人。

我们非常感谢您提供的任何帮助。最好, 学家

答案 0 :(得分:0)

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

其次,REST API返回一个数组,您可以从dataSourceBindings中删除resultTemplate定义:

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

另一方面,没有办法调试它,只需在点击下拉列表控件时捕获请求。
