我对使用 Node.js 还很陌生。我一直在寻找一种解析和查询 JSON 对象的好方法。我将以下 JSON 对象作为文件加载。

[
{"Key":"Accept","Values":["Application/x-www-form-urlencoded","Application/Json","Application/Xml"]},
{"Key":"Accept-Charset","Values":["UTF-8", "ISO-8859-1"]},
{"Key":"Accept-Encoding","Values":["compress", "gzip"]},
{"Key":"Accept-Language","Values":[]},
{"Key":"Accept-Ranges","Values":[]},
{"Key":"Age","Values":[]},
{"Key":"Allow","Values":[]},
{"Key":"Authorization","Values":["Bearer"]},
{"Key":"Cache-Control","Values":[]},
{"Key":"Connection","Values":[]},
{"Key":"Content-Encoding","Values":[]},
{"Key":"Content-Language","Values":[]},
{"Key":"Content-Length","Values":[]},
{"Key":"Content-Location","Values":[]},
{"Key":"Content-MD5","Values":[]},
{"Key":"Content-Range","Values":[]},
{"Key":"Content-Type","Values":["Application/x-www-form-urlencoded","Application/Json","Application/Xml"]},
{"Key":"Date","Values":[]},
{"Key":"ETag","Values":[]},
{"Key":"Expect","Values":[]},
{"Key":"Expires","Values":[]},
{"Key":"From","Values":[]},
{"Key":"Host","Values":[]},
{"Key":"If-Match","Values":[]},
{"Key":"If-Modified-Since","Values":[]},
{"Key":"If-None-Match","Values":[]},
{"Key":"If-Range","Values":[]},
{"Key":"If-Unmodified-Since","Values":[]},
{"Key":"Last-Modified","Values":[]},
{"Key":"Max-Forwards","Values":[]},
{"Key":"Pragma","Values":[]},
{"Key":"Proxy-Authenticate","Values":[]},
{"Key":"Proxy-Authorization","Values":[]},
{"Key":"Range","Values":[]},
{"Key":"Referer","Values":[]},
{"Key":"TE","Values":[]},
{"Key":"Trailer","Values":[]},
{"Key":"Transfer-Encoding","Values":[]},
{"Key":"Upgrade","Values":[]},
{"Key":"User-Agent","Values":[]},
{"Key":"Via","Values":[]},
{"Key":"Warning","Values":[]}
]

我希望能够按值查找键并返回值数组。

例如,我如何找到键等于 Content-Type 的值。

预先感谢您的帮助
