VSTS任务输入dataSourceBindings不工作
我正在维护一个带有几个构建任务的VSTS/TFS扩展和一个带有一些dataSources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填充了来自服务端点中定义的dataSources之一的信息的pickList。
下面是我在扩展清单中的端点/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>"
}
}以下是task.json文件中相关的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\": \"{{.}}\"},{{/.}}"
}
]在我本地的TFS 2017上安装扩展以进行测试后，我在New service endpoint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凭据，设置了正确的凭据。使用我定义的TestConnection dataSource验证连接。
然而，当我去查看我的一个构建任务时，它是空的，这个列表应该用来自dataSource ListApplication的响应填充。
似乎问题可能出在我在dataSourceBinding中定义的鼠标模板。这是我应该从dataSource中的REST调用中得到的：
[
"A Customer Portal",
"A Fine PHP Application",
"A Simple Chess Game"
]在应用jsonpath之后。使用dataSourceBinding中定义的模板从命令行运行mustache，我得到这样的结果(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"},这正是我所期望的。
你知道为什么这可能不起作用吗？有没有办法调试它？有没有办法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文件中可能存在的拼写错误之外，这里可能存在不同的故障点( REST调用jsonpath、八字胡模板……我还是个盲人。
我们非常感谢您能提供的任何帮助。best，J.

首先，如果apps/list接口返回数组对象(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中移除resultTemplate定义：
"dataSourceBindings": [
{
"target": "kiuwanappname",
"endpointId": "$(kiuwanConnection)",
"dataSourceName": "ListApplications"
}
]另一方面，没有办法调试它，只能在单击dropdownlist控件时捕获请求。
