PostResponseOutput(TextedValue):Promise<any>
{
var options = {
    method: 'POST',
    url: 'http://NHSSQLCHNE8105:8081/ctakes-web-rest/service/analyzejson? 
pipeline=default',
    headers: {
        'Accept': 'application/json',
        'Content-Type' : 'application/json'
    },
    body: TextedValue
};
await request(options, callback);
async function callback(error, response, body) {
    if (!error && response.statusCode == 200) {
        var info = await JSON.parse(body);    
}  
}}

使用npm请求，我正在获取json的正文并使用 JSON.parse（body）将下面的JSON文件转换为对象列表。我需要访问子对象中的数组。但由于孩子反对会根据我们提供的输入动态更改。我无法在代码中获取子对象的数组。任何人都可以帮忙从没有父对象的阵列中获取访问子对象。

我需要删除动态更改的子对象并需要访问父对象的数组。注意：PARENT OBject不会根据input进行更改。它将基于输入内容具有或不具有值

    }
}

我已加粗**子对象，这些子对象将根据输入。目前，我已经将Admit作为Postmantool中的输入

您可以使用Object.values检索所有子对象值而无需知道键。这将是所有子项的所有值的数组。因此，对于您的对象，您可以使用以下命令访问数组：

let Admit = {
    "Allergy": {},
    "Others": {
        "Health Care Activity~T058~Hospital admission": [
                "codingScheme: SNOMEDCT_US",
                "code: 32485007",
                "cui: C0184666",
                "semanticType: Health Care Activity",
                "tui: T058",
                "preferredtext: Hospital admission"
            ]
    },
     "AnatomicalSiteMention": {}
     // etc...
}

let othersObj = Admit.Others
// children will have all the values of `others` children
// you don't need to know 'Health Care Activity~T058~Hospital admission' 
let children = Object.values(othersObj)
console.log(children[0])

您只需要小心一点，就知道可能有多少个孩子。的about假设只有一个，因此我们可以使用children[0]来访问它。

需要从Javascript中的Parent对象访问Child对象的数组
