我创建了一个与REST API对话的任务，用于检索2个选项列表的值。 当仅使用jsonpath时，填充第一个下拉框可以正常工作。 基于第一个选项列表，我想要检索第二个列表的值。
我尝试了一些变化，我正在尝试这样的事情： 我在第一次休息时收到的json类似于：
{
"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，并且需要第二个选项列表中属性的id。 我在task.json中创建了以下数据源绑定。当然，目标存在于任务中。 task.json：

"name": "Spinup",

赞赏的想法！
答案 0 :(得分：2)
在第一个数据源中尝试使用它：
{
"dataSourceName": "dsList1",
"endpointId": "$(connectedServiceName)",
"target": "list1",
"selector": "jsonpath:$.attributes[*].name",
"keySelector": "jsonpath:$.attributes[*].value.sdk-object.id"
}
更新：
你试图使用＆＃34; platformTypeId＆＃34;在vss-extension.json文件中，当它在task.json中定义时，这会导致您在注释中提到的错误消息。
顺便说一下，我刚注意到你正在使用＆＃34; dataSourceBindings＆＃34;，那么你就不能使用＆＃34; selector＆＃34;和＆＃34; KeySelector＆＃34;解析结果，因为它们用于＆＃34; sourceDefinitions＆＃34;。
要使用＆＃34; dataSourceBindings＆＃34;实现所需的功能，您可以直接在task.json中定义端点URL，而不是在端点贡献中定义数据源。
因此，您可以先移动vss-extension.json文件中的datasources部分，然后在task.json文件中，更改为以下内容：
"dataSourceBindings": [
{
"endpointId": "$(connectedServiceName)",
"endpointURL": "api/configurations/*****/",
"target": "platform",
"resultselector": "jsonpath:$.attributes[*]",
"resultTemplate": "{ \"Value\" : \"{{{value.id}}}\", \"DisplayValue\" : \"{{{name}}}\" }"
},
{
"endpointId": "$(connectedServiceName)",
"endpointURL": "api/configurations/$(platformTypeId)/",
"target": "size"
}
],
