我创建了一个任务，该任务与REST API对话，以重新计算两个选择列表的值。仅使用JSONPATH时，填充第一个下拉框都可以正常工作。基于我想重述第二个列表的第一个选择列表。
我尝试了一些变体，我正在尝试这样的事情：我在第一个休息电话中收到的JSON与：
{
"id": "45",
"href": "https://selfservice/api/configurations/45/",
"name": "Type",
"description": "",
"version": "0.0.4",
"attributes": [
{
"value": {
"sdk-object": {
"type": "ConfigurationElement",
"id": "56"
}
},
"type": "ConfigurationElement",
"name": "win"
},
{
"value": {
"sdk-object": {
"type": "ConfigurationElement",
"id": "57"
}
},
"type": "ConfigurationElement",
"name": "lin"
}
]
}
我尝试在列表中显示属性名称，并需要第二个选择列表中的属性ID。我在task.json中创建了以下dataSourceBindings。当然，任务中存在目标。task.json：

可悲的是，我无法使它起作用。数据源存在于端点，但我不确定如何处理ResultSelector。有人对如何使它起作用有想法吗？关于此的文档不太好。我不熟悉胡须，但是在胡须测试工具中，这似乎可以起作用。
想法被赞赏！
在第一个数据源中尝试一下：
{
"dataSourceName": "dsList1",
"endpointId": "$(connectedServiceName)",
"target": "list1",
"selector": "jsonpath:$.attributes[*].name",
"keySelector": "jsonpath:$.attributes[*].value.sdk-object.id"
}
更新：
您试图在vss-extension.json文件中使用" PlatformTypeid"。
顺便说一句，我只是注意到您正在使用" DataSourceBindings"，然后您不能使用"选择器"one_answers" Keyselector"来解析结果，因为它们用于" SourcedEfinitions"。
要使用" DataSourceBindings"来实现所需的功能，您可以直接定义任务中的端点URL。
因此，您可以首先在vss-extension.json文件中移动数据源部分，然后在task.json文件中移动数据源部分，更改为以下内容：
"dataSourceBindings": [
{
"endpointId": "$(connectedServiceName)",
"endpointURL": "api/configurations/*****/",
"target": "platform",
"resultselector": "jsonpath:$.attributes[*]",
"resultTemplate": "{ "Value" : "{{{value.id}}}", "DisplayValue" : "{{{name}}}" }"
},
{
"endpointId": "$(connectedServiceName)",
"endpointURL": "api/configurations/$(platformTypeId)/",
"target": "size"
}
],
